Temporal lobe epilepsy is one of the most common forms of epilepsy. It can be caused by hippocampal sclerosis or lesions in the temporal lobe. Hippocampal sclerosis involves neuronal loss and gliosis in the hippocampus and is the most common pathological finding in temporal lobe epilepsy patients. Interictal EEG findings like temporal intermittent rhythmic delta activity and temporal sharp waves help lateralize the seizure focus. Video EEG monitoring helps capture seizures and interictal discharges. Treatment involves antiepileptic drugs and potentially resective surgery for drug-resistant cases.
Unilateral lesions of the occipital lobe can cause contralateral homonymous hemianopia and elementary visual hallucinations. Left occipital lesions additionally cause visual object agnosia, while right lesions cause topographic disorientation. Bilateral lesions can induce cortical blindness, visual anosognosia, achromatopsia, prosopagnosia, Balint's syndrome, or simultanagnosia depending on the specific areas involved. Visual agnosia is classified as apperceptive, with inability to integrate object features, or associative, with intact perception but impaired meaning assignment.
The document summarizes Kurt Schneider's concept of first-rank symptoms (FRS) of schizophrenia. Schneider was a German psychiatrist who studied schizophrenia in the early 20th century. He identified 11 symptoms that he believed were pathognomonic of schizophrenia, including auditory hallucinations, thought broadcasting, and somatic passivity. The document outlines each of Schneider's 11 proposed FRS and provides examples. It discusses the evolution of concepts of schizophrenia from Kraepelin to Bleuler. Overall, the summary focuses on Schneider's influential work defining first-rank symptoms to aid in the diagnosis of schizophrenia.
The document summarizes a presentation on thought and thought disorders. It defines thought, describes different types of thinking (fantasy, imaginative, rational), and characteristics of healthy thinking. It then discusses thought disorders, formal thought disorders, and specific disorders like flight of ideas, poverty of speech, circumstantiality, and loose associations. Research on thought disorders in schizophrenia is mentioned, focusing on structural brain abnormalities and biomarkers.
This document discusses disorders of thought and delusions. It defines thought and describes different types of thinking. It then discusses disorders of thought content, specifically delusions. It defines delusions and differentiates them from overvalued ideas. It describes different types of primary and secondary delusions, including delusions of persecution, jealousy, love, grandiosity, and health. It discusses theories about the origins of delusions and how their content is influenced by social and cultural factors.

This document provides an overview of the history, definitions, classification, epidemiology and psychiatric disorders associated with epilepsy. It discusses how epilepsy was viewed in ancient times as a supernatural condition and outlines key developments in understanding including Hippocrates' view of it as a brain disorder. It defines terms like seizure, aura and epilepsy and classifies seizure types. Statistics on prevalence and risk factors for psychopathology in epilepsy are presented. Specific psychiatric conditions like depression, anxiety and inter-ictal psychosis are also examined.
This document discusses disorders of self-experience and awareness. It defines self as how a person views themselves and their identity. There are four main aspects of self-awareness: awareness of existence, self-unity, continuity of identity, and boundaries. Disorders are discussed under each of these categories. For example, depersonalization is a disturbance in awareness of one's own activity where a person feels detached from themselves. Schizophrenia can involve feelings that one's thoughts are being controlled or stolen, disturbing boundaries. The document examines various conditions that can impact self-experience like depression, anxiety, substance use, and neurological disorders.
Treatment resistant schizophrenia & Treatment resistant depressionEnoch R G
This document discusses treatment resistant schizophrenia and provides guidelines for its management. It defines treatment resistance and outlines criteria from Kane and others. Factors associated with poor outcomes are biological, symptomatic, environmental, illness-related and pharmacological. The neurobiology of treatment resistant schizophrenia involves dopamine, glutamate, genetics and neuroanatomy. Management guidelines are provided from NICE and involve trials of clozapine as the gold standard treatment. Clozapine details include pharmacology, dosage, side effects, monitoring and predictors of response. Studies demonstrate clozapine's superior efficacy over other antipsychotics for treatment resistant schizophrenia.
This document summarizes various motor disorders seen in psychiatry, including both subjective and objective motor disorders. Subjective motor disorders include obsessions/compulsions and delusions of passivity. Objective motor disorders include disorders of adaptive movements like expressive movements, reactive movements, and goal-directed movements. It also discusses various non-adaptive movements like tics, tremors, chorea, athetosis, and stereotypies. Other topics covered are motor speech disturbances, disorders of posture, and movement disorders associated with antipsychotic medication.
Disorders of consciousness can affect perception, attention, thinking, and orientation. There are three main types: dream-like changes where consciousness is lowered and hallucinations may occur; depressed consciousness where awareness is reduced; and restricted consciousness where awareness is narrowed to a few ideas. Specific disorders include delirium, characterized by cognitive impairment and fluctuating consciousness; confusion involving disorientation; and twilight states where consciousness is briefly interrupted. Qualitative changes in consciousness are important to understand for clinical and legal purposes.
Myoclonus is characterized by brief, involuntary muscle contractions or inhibitions. It can be classified anatomically based on its physiological origin in the cortex, subcortex, or periphery. Clinically, myoclonus is classified as physiological, essential, epileptic, or secondary. Treatment involves addressing the underlying cause, with anti-seizure medications often used for cortical or cortical-subcortical myoclonus, and benzodiazepines or botulinum toxin injections for other types.
EEG is a non-invasive method to measure electrical activity in the brain. It can help in psychiatry by ruling out physical causes for psychiatric symptoms, aiding in differential diagnosis and treatment selection, and predicting prognosis. EEG findings can provide clues to underlying conditions in disorders like schizophrenia, mood disorders, OCD, panic attacks, dementia, delirium, and substance abuse. However, EEG findings in psychiatry are often nonspecific and EEG has limitations due to only recording cortical activity from the scalp. It currently has no definitive role in diagnosing Axis I or II psychiatric disorders.
This document provides an overview of the neuropsychiatric aspects of epilepsy. It defines key terms like seizure and epilepsy and discusses classifications of seizures and epilepsies. It covers the prevalence, etiology, investigations, and various neuropsychiatric aspects of epilepsy like disorders related to seizure occurrence such as preictal, ictal, peri-ictal, and postictal. It also discusses management approaches aimed at adequate seizure control and patient safety.
Psychogenic nonepileptic seizures (PNES) are not caused by neurological dysfunction but are psychologically determined. Common psychiatric conditions associated with PNES include depression, anxiety, somatoform disorder, PTSD, dissociative disorder, and various personality disorders. A history of sexual or physical abuse is reported in one-third to half of PNES patients. PNES episodes typically last longer than 2 minutes, involve eyes being closed and variable motor movements rather than stereotyped behaviors seen in epilepsy. Diagnosis involves distinguishing PNES from epileptic seizures based on clinical features during and after episodes.
This document defines and classifies hallucinations, which are false sensory perceptions that occur without external stimuli. Hallucinations are categorized by sensory modality (auditory, visual, etc.), complexity, organization, and reality value. Neuroimaging research has found that auditory hallucinations are associated with reduced grey matter in language processing areas of the brain and altered connectivity between these areas and regions involved in control. Current models propose that hallucinations result from overactivity in sensory processing regions combined with weakened top-down control.
Neuroleptic malignant syndrome (NMS) is a life-threatening condition caused by the use of neuroleptic drugs characterized by mental status changes, rigidity, fever, and dysautonomia. Diagnosis requires exposure to neuroleptics and two of the four cardinal symptoms. Treatment involves stopping the causative agents, supportive care, and specific treatments like dantrolene or bromocriptine. Prognosis depends on severity and medical complications, with reported mortality rates of 5-20%.
This document discusses motor disorders and their classification. It covers disorders of adaptive movements including expressive, reactive, and goal directed movements. Disorders of non-adaptive movements like stereotypies, parakinesia, tics, tremors, chorea, athetosis, and spasmodic torticollis are described. Motor speech disturbances, disorders of posture, abnormal complex patterns of behavior like stupor and excitement, and drug-induced movement disorders are also summarized.
The temporal lobe is involved in processing sensory input, memory formation, language comprehension, and emotional processing. It contains structures like the hippocampus and amygdala that are important for memory and emotional associations. Disorders of the temporal lobe can cause problems like epilepsy, memory deficits, language issues like aphasia, and behavioral changes. Temporal lobe epilepsy is a common type of seizure originating in structures of the anteromedial temporal lobe. Bilateral damage to the amygdala and inferior temporal cortex can cause Klüver-Bucy syndrome characterized by changes in behavior and cognition. The temporal lobe also plays a key role in conditions like Alzheimer's disease, frontotemporal dementia, and traumatic brain injury.
This document discusses various neuroimaging techniques used in psychiatry. It begins with a brief history of neuroimaging, including early techniques like ventriculography and CT scans, as well as key developments in MRI, PET, SPECT, and other modalities. The document then explains several common neuroimaging techniques in more detail, such as CT, MRI sequences (T1WI, T2WI, FLAIR, DWI), and MRS. It provides information on the principles, applications, and appearance of structures on different sequences. In summary, neuroimaging allows measurement of brain structure, function and chemistry, and has provided useful insights into psychiatric pathophysiology that could aid diagnosis and treatment development.
This document discusses normal emotions and the assessment of mood and affect in clinical interviews. It defines key terms like feeling, emotion, mood and affect. It describes the basic emotions and normal physiology of emotions, including the role of the autonomic nervous system and brain structures. Assessment of mood involves evaluating qualities like intensity, duration and fluctuations. Assessment of affect involves monitoring body language and facial expressions.
The document discusses various types of memory disorders and distortions, including amnesias, confabulations, déjà vu experiences, and misidentifications. It covers psychogenic and organic causes of amnesia, different types of amnesia like retrograde and anterograde, and syndromes involving memory distortions like Korsakoff's syndrome, Capgras syndrome, and confabulation.
SISCOM may help differentiate PNES from epileptic seizures by showing changes in brain perfusion during seizures in epileptic seizures but not PNES. However, its diagnostic accuracy is limited and normal findings do not rule out epileptic seizures. Overall, EEG monitoring remains the gold standard for differentiating the two.
This presentation gives detailed description of symptoms of catatonia with its etiologies and differential diagnoses. It should help to differentiate catatonia in neurological and psychiatric disorders.
Schizophrenia Spectrum and Other Psychotic DisordersMingMing Davis
Emilio is a 40-year-old man who has been hospitalized 12 times for schizophrenia. He has stopped taking his medication and exhibits disorganized speech, incoherent thoughts, and bizarre behavior such as saying he has been "eating wires and lighting fires." He has a long history of being unable to work or live independently due to his schizophrenia symptoms. Schizophrenia is characterized by disorganized thinking and behavior, and can include positive symptoms like delusions and hallucinations as well as negative symptoms such as lack of motivation. It has unclear causes but likely involves genetic and environmental factors.
This document outlines a presentation on hallucinations. It defines hallucinations and provides details on the different types of hallucinations. It discusses conditions in which hallucinations may occur, phases of hallucinations, and theories on the etiology and assessment of hallucinations. The presentation also addresses nursing diagnoses and a patient's attitude toward hallucinations. It proposes a training program to improve coping methods for auditory hallucinations in psychiatric patients.

This document outlines a presentation on hallucinations. It defines hallucinations and provides details on the different types of hallucinations. It discusses conditions in which hallucinations may occur, phases of hallucinations, and theories on the etiology and assessment of hallucinations. The presentation also addresses nursing diagnoses and a patient's attitude toward hallucinations. It proposes a training program to improve coping methods for auditory hallucinations in psychiatric patients.
The document discusses the definitions and types of hallucinations. It defines hallucinations as perceptions without external stimuli that patients experience as real. It describes the main types as auditory, visual, olfactory, gustatory, and somatic hallucinations. It further categorizes hallucinations based on their triggers, content, and association with different medical and psychiatric conditions.
Schizophrenia is a complex mental disorder that causes distorted thoughts, perceptions, emotions and behavior. It is diagnosed in late adolescence or early adulthood and symptoms include positive symptoms like delusions and hallucinations as well as negative symptoms like lack of emotion and social withdrawal. There are several types of schizophrenia including paranoid, disorganized and catatonic types which are diagnosed based on the predominant symptoms. Treatment involves antipsychotic medication as well as psychosocial therapies and nursing interventions are aimed at building trust, emphasizing reality, and preventing injury during periods of agitation or excitement.
Schizophrenia is a serious mental illness that affects how a person thinks, feels, and behaves. It is difficult for those with schizophrenia to distinguish between real and imagined experiences. Schizophrenia affects approximately 1% of the world's population. While the exact causes are unknown, research on schizophrenia helps further our understanding of the brain and potential treatments.
This document provides information about antipsychotic drugs. It discusses that antipsychotics are mainly used to treat mental illnesses such as schizophrenia and bipolar disorder. There are two main types of antipsychotics: newer atypical antipsychotics and older typical antipsychotics. Antipsychotics are thought to work by altering chemicals in the brain like dopamine and serotonin. The document also summarizes schizophrenia, bipolar disorder, and different types of antipsychotic drugs.
This document discusses disorders of perception including sensory distortions and sensory deceptions. It describes various types of sensory distortions that can occur such as changes in intensity, quality, spatial form, and time perception. It also discusses sensory deceptions like illusions and hallucinations that can occur in different sensory modalities such as visual, auditory, olfactory, gustatory, and tactile. Various neurological and psychiatric conditions that are associated with these perceptual disturbances are provided along with references for further reading.
The document discusses various types of perceptual disturbances and disorders. It describes sensory distortions like constant distortions of real objects. It also discusses sensory deceptions like new perceptions that may or may not be in response to external stimuli. It outlines various changes in intensity of sensations seen in conditions like anxiety, depression, and migraine. It also describes increased or decreased sensitivity to noise. The document outlines various visual perceptual disturbances caused by toxic drugs. It discusses changes in perceived shape, size, and distance of objects seen in various neurological and psychiatric conditions. It also discusses illusions, hallucinations, and other false perceptions seen across organic, neurological, and psychiatric conditions.
This document provides information on forensic psychiatry and common psychiatric terms and symptoms. It discusses topics such as psychiatry, forensic psychiatry, neurosis, psychosis, delusions, hallucinations, and other key concepts. The key points are:
- Psychiatry is the branch of medicine dealing with the study, diagnosis, and treatment of mental illnesses and behavioral disorders. Forensic psychiatry applies psychiatry within the legal system.
- Neurosis involves emotional or intellectual disorders where reality testing is preserved, while psychosis involves a loss of contact with reality.
- Delusions are false beliefs that persist despite evidence. Hallucinations are false sensory perceptions without an external stimulus. Common types of delusions
Hypnosis is an induced altered state of consciousness characterized by heightened focus and suggestibility. It can be self-induced through activities like daydreaming or meditation, or induced by a hypnotist through relaxation and focused attention techniques. While some myths exist around hypnosis involving mind control, research shows subjects maintain voluntary control and hypnosis simply involves using imagination and suggestion to influence perceptions, sensations, and behaviors. Hypnosis has various therapeutic and medical applications and any willing person of average intelligence can experience it, though some are more suggestible than others. Risks are small but safeguards like pre-hypnosis screening are recommended.
This document provides information about schizophrenia from the Department of Psychiatry at Charles University in Prague. It defines schizophrenia, describes its prevalence and typical age of onset. It discusses the work of key researchers in the field like Kraepelin, Bleuler, and Schneider. It outlines the diagnostic criteria according to ICD-10, describes positive and negative symptoms, and lists different subtypes of schizophrenia including paranoid, hebephrenic, and catatonic schizophrenia.
Schizophrenia is a mental disorder characterized by abnormalities in perceiving reality such as auditory hallucinations, disorganized speech and thinking, and significant social dysfunction. It has been recognized for centuries in ancient cultures and was classified as a distinct disorder in 1887. Symptoms are divided into positive symptoms which distort normal functions like delusions and hallucinations, and negative symptoms which diminish normal functions such as reduced emotional expression. Causes include both genetic and environmental factors. Types of schizophrenia include paranoid, catatonic, residual, and schizoaffective disorder. Treatment involves medications which can have side effects as well as developing social skills and avoiding drug use and social isolation to help prevent the disorder.

This document summarizes a mental health consultation for a 78-year-old female patient who is experiencing auditory hallucinations of voices making critical comments about her. The consultation examines whether the hallucinations could be due to schizophrenia, a mood disorder, an organic brain condition, or substance withdrawal. While some factors point to schizophrenia, the late onset of symptoms makes the diagnosis difficult. The consultation recommends increasing the patient's medication and engaging her in distracting activities to help diminish the hallucinations.
The document provides information about schizophrenia and other psychotic disorders:
1. Schizophrenia is characterized by disturbed thoughts, speech, behavior, social withdrawal, poor grooming, abnormal affect, and must include symptoms for 6 months including at least one period of actual psychosis.
2. Other psychotic disorders discussed include brief psychotic disorder, schizophreniform disorder, schizoaffective disorder, delusional disorder, and shared psychotic disorder.
3. Treatment involves antipsychotic medication, psychotherapy, and long-term support, with prognosis varying between disorders but generally chronic in nature.
This document discusses nonorganic sleep disorders, specifically insomnia and hypersomnia. It defines insomnia as a condition of unsatisfactory quantity and/or quality of sleep that persists for a considerable period of time. Hypersomnia is defined as excessive daytime sleepiness and sleep attacks not accounted for by inadequate sleep, or prolonged transition upon awakening. The document provides diagnostic guidelines and differential diagnoses for insomnia and hypersomnia. It also presents two case studies, one of a woman with insomnia and one of a man with hypersomnia.
Dr. Zahiruddin Othman discusses concepts and definitions related to psychosis. Psychosis has been conceptualized in various ways throughout history such as shamanism, demonic possession, lunacy, and witchcraft. Definitions of psychosis focus on symptoms such as delusions and hallucinations. Psychotic symptoms include hallucinations, delusions, disorganized speech, and disorganized or catatonic behavior. Schizophrenia, schizophreniform disorder, brief psychotic disorder, and other psychiatric disorders can involve psychotic symptoms.
The document discusses various types of perceptual abnormalities including sensory distortions, deceptions, and illusions. It describes abnormalities in different senses such as vision, hearing, touch, and others. Sensory distortions can involve changes in intensity, color, shape, size, motion, or location of perceived objects. Illusions can be completion, affective, or pareidolic in nature. Hallucinations are false perceptions without an external stimulus and can occur in any sensory modality. Organic causes as well as psychiatric conditions can produce different perceptual abnormalities. The document provides examples and details of many specific perceptual disorders.
Hypnosis is a special psychological state resembling sleep that allows increased suggestibility. In a hypnotic state, subjects perceive and respond to suggestions even if contradictory to reality. Effects can extend after hypnosis ends. Hypnosis has been used historically for sorcery, medicine, and was studied scientifically starting in the 18th century. Willing subjects are relaxed and focused to enter a trance state where they are responsive to suggestions for altered sensations, memories, behaviors, and can be impervious to pain. Hypnosis degree varies but subjects respond literally and simply like children. A wide range of responses can be induced.

The cost of acquiring information by natural selectionCarl Bergstrom
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.
3. FUNCTIONAL
a rare phenomenon, where in hallucinations are triggered by a
stimulus in the same modality, and co-occur with it.
The hallucination requires the presence of another real sensation
Patient can distinguish between both features from each other
and crucially,the hallucination does not occur without the
stimulus
4. examples
A patient with schizophrenia first heard the voice of God as her clock ticked
Later, she heard voices coming from a running tap and from chirping of the
birds(auditory)
One patient described that she saw the mouths of her collection of dolls
moving. the perception of dolls was necessary to produce the hallucination
but the movements of their mouths was distinct and separate and did not
represent a transformation of that perception ,thus making it a functional
hallucination and not illusion (visual)
A patient told –”jaise jaise bike chalti hai ,usme se bike ki bhi awaz aati hai
and bhagwan ki bhi awaz aati hai” (auditory)
5. A case report from Functional Hallucinations in Schizophrenia Responding to Adjunctive Sodium Valproate research paper :
A single man, aged 30, employed in a factory, presented to our Outpatient Department, in 2007,
with two years’ continuous illness, characterized by persistent auditory hallucinations, secondary
delusions of reference, social withdrawal, and impaired occupational functioning. He also reported
obsessive doubts about routine activities, such as closing doors or taps, and a compulsion to check
whether he had done these properly, despite knowing that this was unnecessary. There were no
mood disturbances or history of substance use. Physical examination and routine laboratory
investigations were unremarkable. He was diagnosed to have paranoid schizophrenia and
obsessive-compulsive disorder, and was treated with risperidone (titrated up to 8 mg/day) and
fluoxetine (titrated up to 80 mg/day). On the above-mentioned medications, he improved
significantly, and was able to return to his job.
However, he was still troubled by a single symptom. His job involved frequent contact with
machinery and motors. Whenever he heard these machines running, he would hear several
unknown male voices abusing or criticizing him. He found these distressing, and this led him to
frequently avoid his work or leave it incomplete. He did not hear these voices at any other time, and
did not report any recurrence of his other symptoms. There was no evidence of other
hallucinations, delusions or obsessional phenomena on interview.
6. REFLEX
Experience of a stimulus in one sense
modality producing a sensory experience
in another k/as SYNAESTHESIA.
Reflex hallucination are morbid form of
synaesthesia
Sometimes occurs under the influence of
hallucinogenic drugs
7.
8. Examples
Feeling of cold in one’s spine on hearing a fingernail
scratch on blackboard
One patient described hearing his own reflection and said
that when attempting to carry out some action he could
hear himself doing so
Patient felt a pain in her head(somatic hallucination) when
she heard other people sneeze(stimulus) and was
convinced that sneezing caused the pain

10. A 41 year old Iranian woman with 3 sisters and 5 brothers is the 7th child of the
family. She has got married 18 years ago and now has 2 daughters. At the first year
of marriage, her family relation with her husband was very good, but a little after
that, problems developed. Although she had a great reliance on her husband, but
always felt lack of affection by her husband and it bothered her. One year ago, she
involved in conditions of depression including: extreme physical exhaustion, crying,
fear of taking responsibility for daily living such as cooking and …, disinterested and
disenjoyment. She always thought suicide by cutting a vessel, but because of
religious beliefs, she never did this.
She visited a psychiatrist and used drugs about 9-10 months. She remained on
nortriptyline . By using drugs, her condition became better, but stopped taking
them, because she did not have a good belief on psychiatric drugs. Some symptoms
emerged 3 months after stopping using medicine. She says: One day, I was sitting
near our garden. I saw a bird sitting on a tree’s leaves and it’s beak was open
because of the hot weather. Suddenly, I sensed bird’s feathers on my body and it’s
feeling because of the heat. Another one, when a child was taking milk from
mother’s breast, I exactly felt flavor of milk, touching breast tissue and even
differences of it between young mother and older one. When my daughter’s finger
cut, I felt the sense of irritation and weakness she had at that time. When our house
hold “Love bird” was cleaning it’s feathers with its back, I felt as if something was
touching my body.

12. AUTOSCOPY/PHANTOM MIRROR IMAGE
Experience of seeing oneself and knowing that it is oneself
It is not just visual hallucination because kinesthetic and somatic
sensation must also be present to give the subject the impression
that the hallucinations is oneself (he-autoscopy)
Can occur in healthy subjects when they are emotionally upset or
when exhausted
In these cases there is some change in the consciousness state
13. AN UNUSUAL CASE OF AUTOSCOPIC HALLUCINATION:
A CASE REPORT AND REVIEW OF LITERATURE
A 27-year young single female belongs to urban nuclear family from upper socio-economic status presented with
insidious onset of symptoms since last five years characterised by auditory hallucination; voices were
discussing and threatening type. In addition to hearing voices, the delusion of persecution, delusion of reference,
poor self-care, and poor social interaction were also present. Gradually her condition deteriorated, stopped going
out of the home, and would remain fearful, not participating in household chores. For these symptoms, was taken
to various faith healers and local quake but had no relief. Since the last two and half years, she started crying on
and off the pattern for about 5-10 minutes about 3-4 times in a day. While crying, she would point out her figures
toward the wall. Later on, she revealed that “she would see herself, i.e. almost the photocopy of her, i.e. “double”
in front of her about 2-3 feet away from her body. She would describe her double with the similar facial features,
colour and style of hair, complexion in fact “it was another me”. She would say that her double would appear
naked to her; it was like her “mirror image” or “self”. She would say that a man would come and would rape with
the “self”. She would have guilt that she could not save the “self” being raped by someone. As her “self” would ask
for help in a loud volume and would cry. She denied having any sensation to hers’ original body. It would occur at
any point in time. She visited various psychiatrists, started on antipsychotic but had not much relief. Compliance
was not so good, citing the reason of no improvement with the drug

15. Occasionally ,autoscopy is a hysterical symptom
Schizophrenic patients have them ,but more common in
acute and sub acute delirious states
Generally associated with lesions of parieto-occipital
region and toxic infective states whose effect is greatest
in basal region
16. A few patients suffering from
organic states look in mirror
and see no image k/as
negative
autoscopy/heautoscopy
Some subjects see their own
internal organs ,psychiatrists
calling it internal
autoscopy/heautoscopy
17. Patient has hallucination that is outside the limits of the sensory field
Jasper called it the phenomenon of "vivid physical awareness" (leibhaftige
Bewusstheit), i.e. an awareness of an external object independent from any
feeling that it related to a sensory perception ("There are patients who have a
certain feeling-in the mental sense-or awareness that someone is close by,
behind them or above them, someone that they can in no way perceive with
the external senses, yet whose actual/concrete presence is directly/clearly
experienced"
18. Patient sees somebody standing
behind them when they are looking
straight ahead
Hears voices talking in kanpur when
they are in gwalior
[can occur in healthy people as
hypnagogic hallucinations]
19. HYPNOGOGIC/HYPNPOMPIC
• Hallucinations occur when the subject is falling asleep or waking
up,respectively
• Hypnogogic occurs just as person is entering Stage 1 sleep
• Hypnopompic occur during REM sleep state
• It has been suggested that hypnopompic hallucinations are often
hypnagogic experiences that occur in morning when the subject is
waking and dosing off again, so that they actually happen when the
subject is falling asleep
20. • Term “hypnopompic” should be reserved
for those hallucinatory experiences that
persist from sleep when the eyes are open
• Hypnagogic hallucinations occur during
drowsiness ,are discontinuous ,appear to
force themselves on the subject and do not
form part of an experience in which the
subject participates as they do in a dream.
They are 3 times more common than
hypnopompic hallucinations
21. • Hypnopompic hallucinations are better
indicator of narcolepsy
• The subject believes that the hallucinations has
woken them up(for eg,hearing the telephone
ring even though it has not).
• Subjects describing hypnogogic hallucinations
often assert that they are fully awake. But, EEG
records show that there is low alpha rhythm at
the time of hallucinations
22. examples
Hypnagogic visual hallucinations can be geometrical
designs ,abstract shapes,faces etc
One of the most common is that of hearing one’s name
called
Voice saying a sentence or phrase that has no discoverable
meaning
23. Can occur in any sense modality
and occur in variety of neurological
and psychiatric conditions
Occur in eye disorders ,CNS
,lesions of optic tract
Complex scenic hallucinations
occur in temporal lobe lesions
24. Charles bonnet syndrome
consists of VHs in absence of
any other psychopathology,
although impaired vision is
present
All dementias , deliriums
,substance abuse are
associated with VHs
25. Phantom limb is most common organic
somatic hallucination (patient believes
he has a limb from which he is not
receiving any sensation either because it
has been amputated or sensory
pathways have been destroyed
In rare cases with thalamo-parietal
lesions the pt. describes a 3rd limb .
Usually occurs after lesions of peripheral
nerve or medulla or spinal cord
26.
27. PSEUDOHALLUCINATIONS
Patients with pseudohallucinations (typically of auditory or
visual nature) usually present to emergency departments or
psychiatric clinics and their symptoms are often associated
with emotional distress and dissociative behavioural
disturbance.
Usually experienced by grieving people , BPD ,people who
have live psychological trauma
28. Pseudohallucinations are often qualitatively
distinguishable from hallucinations caused by brain
disorders such as schizophrenia, Parkinson's disease,
and acute delirium in that they are internally
inconsistent, usually contexual and symbolic, convey
messages that reflect the patient's psychological
distress, and are more likely than hallucinations to be
perceived as internal.
29. INDUCED HALLUCINATIONS
• Happens in case of induced psychotic disorders where the
influence of a patient with psychosis is such that the
relatives and the associates sharing secluded life with the
patient become convinced of patient’s beliefs.
• As patient they may taste peculiar flavour of water
suspecting poisoning or smell the gas from the window
they have been made to inhale
