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.
Schizophrenia is a group of severe brain disorders in which people interpret reality abnormally. Schizophrenia may result in some combination of hallucinations, delusions, and disordered thinking and behaviour.
Contrary to some popular belief, schizophrenia is not split personality or multiple personality. The word “schizophrenia” does mean “split mind,” but it refers to a disruption of the usual balance of emotions and thinking (Mayo, 2013).
Schizophrenia is a chronic condition, requiring lifelong treatment.
hii guys this is my ongoing presentation from my speciality class i hope u guys lije that please so i hope it is been useful for u in ur specialities by getting little help with that

The word delirium means “out of one’s furrow” which refers to the dramatic behavior changes that the person may experience. Some have called delirium "brain failure” because it may represent a variety of caused such as heart failure does in cardiac health.
Delirium is an outcome of a general medical condition, head injury and drug intoxication or withdrawal.
The world’s population is ageing rapidly, and with it is coming to a significant increase in the number of
older people with dementia. This increase presents major challenges for the provision of healthcare
generally and for dementia care in particular, for as more people have dementia, there will be more
people exhibiting behavioural and psychological symptoms of dementia (BPSD).
BPSD exact a high price from both the patient and the caregiver in terms of the distress and disability
they cause if left untreated. BPSD is recognisable, understandable and treatable. The recognition and
appropriate management of BPSD are important factors in improving our care of dementia patients
and their caregivers,

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

3. HISTORY:
The oldest detailed account of epilepsy is on a
Babylonian tablet dating as far back as at least
2000 BC. It emphasizes the supernatural nature of
epilepsy, with each seizure type associated with
the name of a spirit or god - usually evil.
Greek concept (5th century BC) describes it as
"The Sacred Disease"
4. HISTORY:
The word "epilepsy" is derived from the Greek
"epilepsia" which means "to take hold of" or "to
seize.”
Hippocrates viewed epilepsy as a brain disorder,
but his view did not begin to take root until the
18th and 19th centuries.
5. HISTORY:
People with epilepsy were viewed with fear,
suspicion and misunderstanding, and were
subjected to enormous social stigma. They were
treated as outcasts and punished.
However, some of them succeeded and, in fact,
became famous the world over. Among them were
Julius Caesar, Czar Peter the Great of Russia, Pope
Pius IX, the poet Lord Byron and others.
6. HISTORY:
The foundation of our modern understanding was
laid in the 19th century with the proposal by
Hughlings Jackson (1873), a London neurologist,
that seizures were the result of sudden brief
electro-chemical discharges of energy in the brain
- the character of the seizures depending on the
location and function of the seat of the discharges.
In 1920s, Hans Berger, a psychiatrist, developed
the human electroencephalograph (EEG )
7. HISTORY:
Emil Kraepelin emphasized that epileptic patients
possessed personality changes & a predisposition
to psychosis
Psychiatric disorders were thought to result from
psychosocial difficulties in epilepsy
Defining temporal lobe epilepsy opened up
research into disturbances in limbic or emotional
brain
8. DEFINITIONS:
Seizure is "a transient occurrence of signs and/or
symptoms due to an abnormal, excessive or
synchronous neuronal activity in the brain"
However, a(single) seizure can occur in an
otherwise healthy individual. Such individuals are
generally not considered to have epilepsy.
Epilepsy is a neurological condition characterised
by a tendency to unprovoked and recurrent
seizures
9. DEFINITIONS:
Epileptogenesis: Epileptogenesis is the process
by which the previously normal brain is
functionally altered and biased towards the
generation of the abnormal electrical activity that
subserves chronic seizures.
The concept of a ‘mechanism of epilepsy’ refers to
any biological feature of the brain that drives or
supports recurrent, unprovoked seizures.
10. Examples of these biological features include
molecular, anatomical or circuit level alterations,
such as cell death or dysregulation of an ion
channel or neurotransmitter receptor.
11. DEFINITIONS:
Aura: Simple partial seizures, which may or may
not progress into another seizure type.
They are often mistakenly considered as a
prodrome for a seizure.
Fit: The physical manifestation of a seizure.
12. DEFINITIONS:
Prodrome: A pre-ictal phenomenon characterised
by subjective or objective awareness of a clinical
change that heralds the onset of a seizure, but that
does not form part of it.
13. CLASSIFICATION OF EPILEPSY
Generalised seizures (bilaterally symmetrical
and without local onset)
Tonic, clonic or tonic–clonic ( grand mal)
Absence ( petit mal):
with loss of consciousness only
complex – with brief tonic, clonic or automatic
movements
14. CLASSIFICATION OF EPILEPSY
Generalised seizures contd…
Lennox–Gastaut syndrome
Juvenile myoclonic epilepsy
Infantile spasms (West syndrome)
Atonic (astatic, akinetic) seizures (sometimes with
myoclonic jerks)
15. CLASSIFICATION OF EPILEPSY
Partial or focal seizures (seizures that begin
locally)
Simple (without loss of consciousness or alteration
in psychic function):
motor
somatosensory
autonomic
pure psychic
Complex (with impaired consciousness)
16. CLASSIFICATION OF EPILEPSY
Special epileptic syndromes
Myoclonus and myoclonic seizures
Reflex epilepsy
Acquired aphasia with convulsive disorder
(Landau Kleffner Syndrome)
Febrile and other seizures of infancy and
childhood
Functional non-epileptic attacks
17. CLASSIFICATION OF SEIZURES
The International League Against Epilepsy
(ILAE) 2017 describes seizures according to these
criteria
i. where seizures begin
ii. awareness in focal seizures
iii. motor and other symptoms in focal seizures
18. Classification of seizures

20. EPIDEMIOLOGY:
Seizure disorders are common and usually have an
early onset.
Epilepsy affects 20 to 40 million people worldwide
and has a prevalence of at least 0.63 percent and an
annual incidence of approximately 0.05 percent.
The overall incidence is high in the first year, drops
to a minimum in the third and fourth decades of
life, then increases again in later life.
21. EPIDEMIOLOGY:
More than 75 percent of patients have their first
seizure before 18 years of age, and 12 to 20 percent
have a familial incidence of seizures.
Among adults, the most common seizures are
complex partial and generalized tonic-clonic
seizures.
22. EPIDEMIOLOGY:
It is estimated that there are more than 10 million
persons with epilepsy in India.
Its prevalence is about 1% in our population.
The prevalence is higher in the rural (1.9%)
compared to urban population (0.6%)
NMHS (2015-2016): Prevalence of epilepsy (GTCS
only) is 0.3%
23. EPIDEMIOLOGY:
Psychiatric comorbidity occurs in 20-40% of
people with epilepsy.
More psychopathology in people with epilepsy
than in other chronic neurological conditions.
24. Psychopathology in epilepsy
Epilepsy patients are prone to psychosis,
depression, personality disorders, hypo-sexuality,
& other behavioural disorders
Psychiatric disturbances are common in patients
with complex partial seizures than GTCS

ii. Lennox - Gastaut syndrome
iii. Progressive myoclonic epilepsies
iv. Epilepsy with continuous spike-and-wave during
slow-wave sleep

iii. Personality disorder
iv. Dementia
v. Dissociative seizures
28. PRE-ICTAL DISORDERS
PRODROME
Subjective symptoms occurring in the hours or
even days leading up to a seizure seen in 7-20%
patients
Gradual onset; prolonged duration; affective
symptoms
Ill-defined, non-specific feelings – malaise,
headache, tiredness, irritability, dysphoria
29. ICTAL DISORDERS
EPILEPTIC AURA
In simple partial seizure, ictal psychiatric
phenomena may be the only manifestation of
seizure
In complex partial seizures aura precedes
clouding of consciousness & loss of awareness
30. Ictal aura is brief, paroxysmal & highly
stereotyped
Hallucinations, forced thinking or crowding of
thoughts can mimic psychosis
Ictal anxiety can mimic panic disorder
Clouding of consciousness with amnesia for the
episode can be present
31. EPILEPTIC AUTOMATISMS
More or less coordinated, repetitive motor
activity usually occurring when cognition is
impaired & for which subject is usually amnesic
afterwards
Automatic fumbling behaviour, such as lip-
smacking, hand-rubbing, picking at objects,
walking in circles, repeating meaningless
phrases, or undressing may be seen
32. Terms describing automatisms
Oro-alimentary: Lip-smacking, lip-pursing,
chewing, licking, tooth grinding or swallowing
Mimetic: Facial expression suggesting an
emotional state, often fear
Manual or pedal: Indicates principally distal
components, bilateral or unilateral Fumbling,
tapping, manipulating movements
33. Terms describing automatisms
Gestural (often unilateral): Fumbling or
exploratory movements with the hand, directed
toward self or environment.
Hyperkinetic: Involves predominantly proximal
limb and axial muscles. Increase in rate of ongoing
movements or inappropriately rapid performance
of a movement.
Hypokinetic: Decrease in amplitude and/or rate
or arrest of ongoing motor activity
34. Terms describing automatisms
Dysphasic: Impairment of language without
dysfunction of relevant primary motor or sensory
pathways, manifested as impaired comprehension,
anomia, paraphasic errors or a combination of
these.
Gelastic: Bursts of laughter or giggling, usually
without an appropriate affective tone
Dyscrastic: Bursts of crying
35. Terms describing automatisms
Vocal: Single or repetitive utterances consisting of
sounds such as grunts or shrieks
Verbal: Single or repetitive utterances consisting
of words, phrases or brief sentences
Spontaneous: Stereotyped, involve only self,
virtually independent of environmental influences
Interactive: Not stereotyped, involve more than
self, environmentally influenced
36. NON-CONVULSIVE STATUS EPILEPTICUS
Prolonged electrographic seizure activity results
in non-convulsive seizure symptoms
Most common forms are complex partial status
& absence status
Mental state abnormalities & behavioural
disturbance that results may be mistaken as
psychiatric disorder
37. Partial non-convulsive status epilepticus
Complex partial status is the most common form
of non-convulsive status
Classical picture is one of fluctuating delirium
with motor automatisms
Psychomotor agitation or retardation, affective
disturbances, hallucinations, paranoid ideation,
or catatonic picture may be seen
38. Simple partial status commonly involves focal
motor seizures
Subjective experiential phenomena in absence of
impaired consciousness (aura continua) are the
most likely to be confused with psychiatric
disorder
Absence status: prolonged state of impaired
consciousness associated with continuous 3-Hz
spike-wave EEG abnormality
39. POST – ICTAL DISORDERS
DELIRIUM
Epileptic seizures begin abruptly but recovery
occurs gradually
Typically, patients are alert and responsive within
15 minutes
On occasions, full recovery of consciousness may
take much longer, especially in the elderly or in
patients with learning difficulties
40. POST-ICTAL PSYCHOSIS
Brief self-limiting episodes of psychosis that are of
abrupt onset and follow seizures
Accounts for about 25% of epileptic psychoses
Prevalence is around 6%
Epilepsy has usually been present for over 10 years
before the first episode
41. Risk factors for development of post-ictal
psychosis include:
i. bilateral seizure foci
ii. processes associated with bilateral limbic
lesions (e.g. encephalitis, head injury)
iii.relative increase in seizure frequency preceding
the psychotic symptoms
42. Precipitating event can be an exacerbation of
seizures followed by a lucid interval lasting 2 -
72 hrs (mean-1 day) where patient appears
normal
Onset of psychotic symptoms is sudden &
dramatic accompanied by marked agitation &
behavioural disturbance
Affective symptoms with grandiose & religious
delusions & simple auditory hallucinations are
common
43. Duration of postictal psychosis is generally short
(Mean – 3.5 days) with a range from 16 hours to
18 days
EEG may show diffuse background slowing or
an increase in inter-ictal epileptiform
abnormalities
Episodes are self-limiting hence treatment with
antipsychotics is usually not indicated
44. Severe agitation warrants hospitalisation and
treatment with benzodiazepines or low dose
antipsychotics
14 - 20% of patients with recurrent postictal
psychosis will develop chronic inter-ictal
psychoses after several years
There is no prophylactic role for antipsychotics
to prevent chronic psychosis
45. Psychotic symptoms often worsen with increasing
seizure activity
Rarely, psychotic symptoms alternate with
seizures & when patients are seizure free they
manifest mainly paranoid psychotic symptoms
EEG normalizes during a psychotic episode is
called forced or paradoxical normalization
Alternating psychosis or forced
normalization
46. INTER – ICTAL DISORDERS
DEPRESSION
Depression and anxiety are the most frequently
encountered inter-ictal psychiatric disorders in
epilepsy
Estimated prevalence is 20-70%
47. The clinical picture is one of chronic dysthymia
which is interrupted at frequent intervals by
brief periods of normal mood
Other symptoms include atypical pain, phases
of euphoric/dysphoric affect, anxiety and phobic
symptoms
Antiepileptic drugs can lower serum folate levels
and manifest with depressive symptoms
48. Escitalopram & Sertraline are preferred first-
line medications
MAO inhibitors have lower effect on seizure
threshold and TCA have higher effect
Antidepressant dose should be increased
slowly in small increments
49. ANXIETY
The most frequent diagnoses are agoraphobia,
generalised anxiety disorder & social phobia
Fears (phobic anxiety), often relate to the
perceived risk of personal injury & brain
damage, & having seizures in unfamiliar
situations
50. INTER-ICTAL PSYCHOSIS
Prevalence is between 3 & 7%
Psychotic symptoms not temporally related to
seizure activity & mental state characterised by
delusions & hallucinations in clear consciousness
Bizarre or disorganised behaviour, thought
disorder, personality change, negative symptoms
of schizophrenia or affective changes are not
commonly seen
51. Mean age of onset is 30; after a mean duration of
epilepsy of 10-15 years
Risk factors include:
i. early age of onset of seizures
ii. poorly controlled partial complex seizures
(usually with secondary generalization)
iii. Temporal lobe or left sided lesions
52. TEMPORAL LOBE EPILEPSY
Temporal lobe epilepsy (TLE) is the most common
of the anatomically defined syndromes,
accounting for around 60% of all patients with
localisation-related epilepsy.
Temporal lobe seizures produce the most varied
and complex auras of all.
The most frequent cause of TLE is hippocampal
sclerosis, also known as mesial temporal sclerosis
53. Other causes of TLE include dysembryoplastic
neuroepithelial tumours, cavernous angiomas,
gliomas, cortical dysplasia and gliosis secondary to
encephalitis or meningitis.
Temporal lobe seizures may take the form of
simple and complex partial seizures, with both
occurring in some 70% of patients.
A variety of autonomic features and visceral
sensations figure prominently in temporal lobe
auras.
54. The epigastric aura is the most common, being
reported by up to 50% of patients.
Other autonomic effects include changes in skin
colour, blood pressure, heart rate, perspiration,
salivation and piloerection. Subjective dizziness is
common.
Affective experiences are a feature of
approximately 25% of temporal lobe auras. The
most common is anxiety, which is often intense
(ictal fear)
55. Vocalisation is seen in approximately 50% of
temporal lobe seizures.
The essential quality of recognition may change,
with strong feelings of familiarity or unfamiliarity
leading to déjà vu and jamais vu.
Altered perceptual experiences include both
distortions of real perceptions (illusions) and
spontaneous hallucinations.
56. Hallucinations of taste (gustatory) and smell
(olfactory) derive from medial temporal lobe
structures, particularly the amygdala, and are of
considerable significance for the diagnosis of TLE.
The most frequent automatisms are oro-
alimentary (lip smacking, chewing, swallowing)
and gestural (fumbling, picking, rubbing
movements)
57. FRONTAL LOBE EPILEPSY
20–30% of localization-related epilepsy
Post-traumatic aetiology is common, although
tumours and cortical dysplasia are also frequent.
Frontal lobe seizures tend to begin and end
abruptly, are brief (usually less than 1 minute),
often frequent, and show a tendency to occur at
night and in clusters.
58. Motor phenomena, which may include complex
posturing and behavioural automatisms, are
usually present.
Focal motor seizures may occur as a special form of
status epilepticus (Epilepsia partialis continua)
Speech arrest is a feature of dominant hemisphere
frontal seizures but speech automatisms
accompanying hypermotor seizures arising from
the non-dominant hemisphere may also be
dramatic, with screaming and swearing.
59. PARIETAL LOBE EPILEPSY
Rare, less than 5% of localisation-related epilepsy
Tumors are the most common aetiology.
Somatosensory auras are reported by some 80% of
patients, with elementary paraesthesia by far the
most common feature like tingling, numbness,
prickling, crawling or electrical sensations
60. OCCIPITAL LOBE EPILEPSY
5–7% of localisation- related epilepsy but is probably
under-recognised.
Childhood syndrome are frequently misdiagnosed as
migraine and in adults occipital lobe seizures
notoriously mimic other partial seizures because of
rapid propagation to temporal and frontal lobes.
Elementary visual hallucinations are the
hallmark of occipital seizures but are not seen in all
cases
61. The hallucinations consist mainly of bright, coloured
spots, circles, balls or blobs. They typically appear in
the contralateral hemifield and move, flash or twinkle.
Negative phenomena, such as scotoma, ‘black or white
outs’, and ictal amaurosis are less common.
Complex visual illusions and hallucinations are
associated with temporal lobe seizures but may be
seen with occipito-temporal foci.
Common causes of occipital lobe epilepsy include
tumours, trauma and developmental malformations.
62. EPILEPSY AND SUICIDE
Risk of suicide is 2.4 times higher in patients with
epilepsy
11–12 times higher in those with epilepsy and
anxiety or psychosis
32 times higher in those with epilepsy and
depression
63. Death by suicide occurs in 3 to 7 percent of
epilepsy patients
Higher risk of suicide is associated with early age
at onset of epilepsy, particularly during
adolescence
Contributors to successful suicides include
paranoid hallucinations, agitated guilt to kill
themselves, & occasional ictal command
hallucinations to commit suicide
64. Personality changes associated
with epilepsy
Extent of personality disorders in association
with epilepsy is 0.7–2.0% (most commonly
borderline)
In partial epilepsy (particularly TLE), rates of
personality disorder range from 13 to 35%
Treatment-refractory epilepsy commonly
associated with dependent & avoidant
personality disorders
65. Organic personality disorder: some people with
epilepsy (complex partial seizures; particularly TLE)
develop behavioural changes like:
Viscosity – a tendency for prolonged interpersonal
contact, with pedantry & lack of socially
appropriate ending of conversations
Hyposexuality – decreased libido & impotence
66. Religiosity – very strong preoccupation with
religion and philosophy
Hypergraphia – compulsive writing
Aggression – increased incidence of inter-ictal
violence & hostility
Combination of these traits is sometimes
referred to as Gastaut–Geschwind syndrome
67. FUNCTIONAL NON-EPILEPTIC ATTACKS
These are a diverse group of disorders in which
paroxysmal events may be mistaken for epilepsy,
but are not caused by epilepsy
Origin: physiological (10–20%)
psychogenic (80–90%)
68. 5–20% of patients in epilepsy clinics have only
non-epileptic fits
About 80% of patients with psychogenic non-
epileptic seizures are women & are aged between
15 - 35 years
Non-epileptic seizures may occur in people with
epilepsy (about 33%)
69. Common clinical presentation of non-
epileptic fits:
Panic attack – may resemble an epileptic
seizure and loss of consciousness may occur
Avoidance attack – typically this occurs when
the individual is unable to cope with a stressful
situation; the person may fall to the floor and
remain inert, with reduced muscle tone
70. Abreactive attack – occurs as a delayed
response to highly stressful experiences, and
often happens towards the end of the day;
hyperventilation may precede increased body
tone and thrashing of the limbs
Simulated attack – conscious or unconscious
simulation of an epileptic seizure, usually
involving some kind of gain
72. Comparative semiology of dissociative and epileptic
seizures

EPILEPTIC
SEIZURES
Duration > 2 min Common Rare
Motor features
• Gradual onset Common Rare
• Fluctuating course Common Very rare
• Eyes closed Common Rare
• Thrashing, violent movements Common Rare
• Side-to-side head movements Common Rare
• Asynchronous clonic movements Common Very rare
• Pelvic thrusting Occasional Rare
• Opisthotonous Occasional Very rare
• Automatisms Rare Common
73. Comparative semiology of dissociative and epileptic
seizures
DISSOCIATIVE
SEIZURES
EPILEPTIC
SEIZURES
Weeping Occasional Very rare
Recall for period of
unresponsiveness
Common Very rare
74. Observational features suggestive of non-
epileptic fits:
Undulating motor activity
Convulsion lasting >2 minutes
Resisted lid opening
Rapid postictal re-orientation
Asynchronous limb movements
Lack of cyanosis
Retained awareness of surroundings in apparent
generalised fits
75. Common investigations in functional non-
epileptic attacks:
EEG: single inter-ictal EEG may not be helpful in
diagnosis
Provocation procedures: commonly used are
hyperventilation, photic stimulation or sleep
deprivation
Serum prolactin: may not be very helpful due to
low sensitivity & specificity
Home videos can be a very helpful
Gold standard is video-EEG telemetry
76. Paroxysmal neurological disorders that
may be mistaken for Epilepsy:
Transient ischaemic attacks
Migraine
Vertigo
Hyperekplexia
Paroxysmal movement disorders
Sleep disorders
Narcolepsy
Non-REM disorders
REM sleep behaviour disorder
77. AGGRESSION IN EPILEPSY
Most aggression among epilepsy patients is not
related to epileptiform activity
It is usually associated with psychosis or with
intermittent explosive disorder & correlates with
subnormal intelligence, lower socioeconomic
status, childhood behaviour problems, prior head
injuries, & possible orbital frontal damage
78. Simple violent automatisms, such as spitting or
flailing the arms, can occur at the onset of
complex partial seizures
Non-directed violent movements, aimless
destructive behaviour, or angry verbal outbursts
occur during postictal delirium
79. EPILEPSY AND SEXUAL DYSFUNCTION
Men with epilepsy report less sexual interest. A
history of erectile dysfunction is found in up to
57%
In women, hyposexuality is common with
abnormalities of arousal and orgasmic dysfunction
Can be explained by biological factors (low
testosterone), medication related, or psychosocial
factors
80. COGNITIVE FUNCTION IN EPILEPSY
Cognitive deficits are present at the time epilepsy
is first diagnosed & may even precede the onset of
seizures
10–20% children with epilepsy have impaired
intellectual development manifest as persistent or
progressive cognitive deficit
Progressive decline of memory seen in 50 %
patients with uncontrolled TLE
81. Antiepileptic drugs are an important cause of
cognitive problems & is likely in patients taking
two or more antiepileptic drugs
Cognitive deficits are possible cumulative effects
of neuronal damage incurred through repeated
seizures, brain injury secondary to trauma or
status epilepticus & psychosocial impact of
disorder
82. TREATMENT OF EPILEPSY
Anti-epileptic medications
Epilepsy surgery
Vagal nerve stimulation

84. Neuropsychiatric aspects of
epilepsy surgery
Patients with epilepsy who have not responded
to two or more anti-epileptic drugs could be
considered for epilepsy surgery
Surgery involves removal of epileptogenic focus
Most common surgery done is anterior temporal
lobectomy. Others are hippocampectomy,
lesionectomy & multiple subpial transection
85. Seizure-free or near seizure-free rates as high as
80–90% have been achieved using surgery
About a third of patients can present with
anxiety & depression 6–12 weeks after the surgery
irrespective of surgery outcome
De novo psychosis is rarely seen post-epilepsy
surgery (0.5–1%)
86. Vagal nerve stimulation
The procedure involves intermittent electrical
stimulation of the vagus nerve via a stimulator
inserted surgically over the anterior chest wall.
The mechanism of action is unknown.
VNS is usually considered for patients who prove
unsuitable for epilepsy surgery.
87. Overall, a 50% reduction in seizure frequency is
seen in approximately 30% of patients.
VNS is generally well tolerated: the main side
effects are intermittent hoarseness of the voice and
throat discomfort during stimulation but patients
usually habituate to this.

Since 1981, Classification was difficult if onset unknown, and some important types were not included
Lack of knowledge about the onset makes a seizure unclassifiable with the 1981 system
Side effects – low folate
DD for panic disorder: no situational triggers; nature of emotion; no impending doom or cognitive manifestations
ECT HAS been used in refractory cases
Also called schizophreniform or schizophrenia-like psychosis of epilepsy
Also called hystero-epilepsy, hysterical seizures, pseudoseizures, pseudo-epileptic seizures, non-epileptic pseudoseizures, hysterical epilepsy
Incontinence, injury, nocturnal episodes frequent in both groups
Low serum testosterone levels implicated
Localisation related especially right temporal focus affecting limbic regions affect sexual function
