The diagnostic assessment and treatment and treatment planning in psychiatry is a dynamic process that integrates the biological, psychological, social, and behavioral paradigms to develop a plan of action that provides a rational for the types of interventions employed to sustain the therapeutic alliance and relieve suffering.
This is a presentation done on 4/6/11 for the Grand Rounds at Wayne State university by Pallav Pareek M.D.
This presentation talks about the concept of prdrome as it is(if?) applicable to schizophrenia, and if schizophrenia is becoming more of a preventable illness as science progresses. If so what are the various ways and means in which we can accomplish this prevention.
Amidst so much controversy on the issue , whether there is a prodrome for this illness or not, here I have tried to present the recent advances in this field and the recent scientific literature in this regard.
Morbid expressions of emotion from Fish’s Clinical Psychopathology including parathymia, flattening, stiffening, incongruity and lability of affect, smiling depression and affective incontinence.

Somatoform disorders
A disorder in which people have physical illnesses or complaints that cannot be fully explained by actual medical conditions
Dissociative disorders
A personality disorder marked by a disturbance in the integration of identity, memory, or consciousness.
Historically, both somatoform and dissociative disorders used to be categorized as hysterical neurosis
in psychoanalytic theory neurotic disorders result from underlying unconscious conflicts, anxiety that resulted from those conflicts and ego defense mechanisms
"schizophrenia" "split mind" but it refers to a disruption of the usual balance of emotions and thinking.
Schizophrenia is chronic and a severe brain disorder in which people interpret reality abnormally. Schizophrenia may result in some combination of hallucinations, delusions, and extremely disordered thinking and behavior .

Diagnostic overview
Schizophrenia is the most debilitating form of mental illness . This disorder which can come on quite suddenly distorts a person thoughts , perceptions and mood, and leaves them unable to meet the ordinary demands of life .
There is no single test to determine who suffers from schizophrenia. Instead the diagnoses is made when a person expresses a collection set of symptoms. The symptoms can be divided into three categories. One positive symptoms two negative symptoms and three social dysfunction.
One positive sentence
Positive symptoms include overt behaviors that are unusual and that interferes with the persons ability to interact in a daily life. The Two most common types of positive symptoms include delusional and hallucinations. It is essential to understand the difference between these two.
A delusion is a firmly held beliefs that is not grounded in real life. There are many types of delusions for example when a person vastly overestimate his or her importance we would ...

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Schizophrenia: Theories and Treatments
1.
2. Paranoid
› Preoccupation with one or more delusions or
frequent auditory hallucinations. None of the
following are prominent; disorganised speech,
disorganised or catatonic behaviour, the flat or
inappropriate effect
Catatonic
› At least two of the following is present; immobility
including waxy flexibility, stupor, excessive motor
activity, extreme negativism, mutism, posturing,
prominent mannerisms, echolalia
3. Disorganised
› Disorganised behaviour, disorganised speech
and the flat effect are all present
Undifferentiated
› A mixture of other symptoms from other subtypes
of the disorder
Residual
› An absence of prominent delusions or
hallucinations, disorganised speech and
catatonic behaviour. There are negative
symptoms or 2 or more symptoms in criteria A in
a less intense form
4. Positive symptoms – additional to reality
› Auditory hallucinations
› Delusions
› Experiences of control
› Disordered thinking
Negative symptoms- things the person is
lacking
› Flat effect
› Alogia – poverty of speech
› Avolition – lack of motivation
5. It was first thought that schizophrenia was
caused by an increase in dopaminergic
activity in the brain – neurons fire too easily
and too often
Inconsistent evidence for the
aforementioned theory led to the theory
that it was heightened sensitivity of
dopamine receptors was to blame for
schizophrenia.
This led to an abundance of dopamine in
the synaptic cleft.
6. Drugs that increase dopaminergic activity,
when taken by health individuals cause
schizophrenic like symptoms
These drugs were also found to exacerbate
psychotic symptoms in those with
schizophrenia
Neuroleptic drugs the block dopaminergic
activity reduce psychotic symptoms
The theory was first amended was difficult
to support due to inconsistent post mortem
evidence
7. Ivernsen (1979) Post mortems of
schizophrenia suffers show high levels of
dopamine
Pearlson et al (1993) PET scans have
reported a substantial increase of D2
receptors in those with schizophrenia
Seeman et al (1993) found a 6 times
greater density of D4 receptors in the
brains of those with schizophrenia
8. Differences in structure and function
Nasrallah et al (1986) found that the
gender difference in the thickening of
the corpus callosum is the opposite in
those with schizophrenia
Jernigan et al (1991) found significant
cell loss in the limbic system – more
specifically the amygdala and
hippocampus
9. Andreason (1990) found significantly
larger ventricles in patients with the
disorder
Liberman (2001) found the same results
Weyandt (2006) linked them to negative
symptoms
Liddle (1996) found that t rest, people
with schizophrenia show underactivity in
temporo frontal areas. Particularly in
chronic patients
10. Gottesman (1991) suggested that
schizophrenia is inherited through genes.
Found concordance rates of 40% for MZ
twins and 17% for DZ twins
Gottesman also found that is both
parents suffer from schizophrenia then
you have a 46% chance of being
diagnosed also compared to a1%
chance in someone selected at random
11. Joseph et al (1991) found concordance
rates of 40% for MZ twins and 7.4% for DZ
twins
Cardno (2002) found concordance rates
of 26.5% for MZ twins and 0% for DZ twins
Higher concordance rates for MZ twins
could be due to greater environmental
similarities
Genetics are only a risk factor and not a
causal factor
12. Tienari (1990) studied 155 adopted
children whose biological mothers had
schizophrenia. Concordance rate of 10%
to 1% in the general public.
Heston (1966) study of 47 mothers with
schizophrenia whose children were
adopted within days by families without
schizophrenia found the incidence of
schizophrenia in those children to be 16%
13. Bentall (1990) stated that hallucinations
occur when people mistake their own
internal, mental or private thoughts for
external, publically observable events
Slade and Bentall (1988) suggested that
hallucinations decrease anxiety
Close and Garety (1998) suggested that
hallucinations actually increased
anxiety
14. Model suggests that sensory information
from the environment triggers hallucinations
People only hallucinate what they believe
already exists e.g. religious experiences
Slade and Bentall
(1988) Five Factor
Model for the onset
of hallucinations
Stress induced arousal
causes info to be
processes incorrectly
meaning they cannot
decide what is real.
15. Two main theories:
› delusions are the result of abnormal
cognitions in reasoning, attention and
memory
› Delusions are the result of abnormal
perceptions
16. Bentall (1991) suggested that paranoid and
persecutory delusions are a defence
mechanism against depression and low self
esteem
Defences are maintained through attention
and memory biases
Mainly external biases where negative
outcomes are attributed to an external cause
e.g. the person is fired, it is not their fault the
management just hate them
Bentall argues that we attempt to explain
discrepancies between our actual self and
ideal self in order to maintain self esteem
17. Delusions are a adaptive and rational
response to abnormal internal events like
hallucinations
Zimbardo (1981) stated that delusions
happen to make sense of a situation
Maher (1974) proposed a model of how
delusions occur. Some cognitions lead to
normal and delusional beliefs, these act as
mini theories that provide order. These
theories are needed when events are not
predictable. Delusional explanations for
unpredictable events bring relief.
18. Manschreck (1979) Delusions occur in a
wide range of disorders where no cognitive
impairment is evident;
Zimbardo (1981) Normal people that
undergo abnormal experiences can also
experience delusions
Theories point to the importance of
attribution and reasoning biases that may
contribute to the maintenance of delusions
but do not provide an explanation for how
schizophrenia is developed
19. Scheff (1966) suggested that Schizophrenia is a
learned social role that is learnt through
labelling
Szasz (1962) once a person has been given a
label they then begin to act accordingly and
become a self-fulfilling prophecy. He also
argued that labelling is a way to control those
that break one or more residual rules
Rosenhan (1973) demonstrates how easy it is to
receive a label. The label stuck with the
participants forever. Their behaviour was a
result of their label once given
20. Bateson et al (1956) stated that sometimes a
child received conflicting messages from their
parents e.g. asked for a hug and then being
pushed away. This is referred to as a ‘double
bind’
They learn that they cannot trust the messages
that they receive from others, their own
emotions and their perceptions.
This may cause them to withdraw socially and
cause the flat effect in those diagnosed.
They may also grow to not trust any
communications , this is shown in those with
paranoid schizophrenia
21. Family Socialisation Theory – families do not always
provide supportive or appropriate environments for
their children
Schismatic families – conflict and division between
the parents where one is competing for the love
and affection of the family members
Skewed families – the balance of power is biased
towards one dominant parent where the children
are encourages to follow their direction
In both families the parent fail to act role-
appropriate. This causes anxiety. Schizophrenia
may be a way to handle conflict
22. The over expression of hostility, critical
comments (both verbal and tone of
voice)and emotion (both positive and
negative)
Brown et al (1958) found that those
released into the care of a family fares
worse than those that lived alone
Butzlaff and Hooley(1998) 70% chance of
relapse within one year in a high EE
environment compared to 30% in low EE
families
23. Conventional Antipsychotics (Neuroleptics)
› Only work on positive symptoms
› They block dopamine receptors
› Have to be taken continuously or
› Have terrible side effects
› Cole et al (1964) – groups taking Chlorpromazine
showed significant improvement over placebo
groups. 76% compared to 25%.
› Some patients fail to respond to treatment
Loeble et al (1992) 16% failed to respond within a
12 month period
24. Atypical Antipsychotics
› Treat both positive and negative symptoms
› Focus less on reducing dopamine and more
on changing the level of serotonin back to a
normal level
› Tend to be affective I those patients that did
not respond to conventional drugs
› Have bad side effects like weight gain,
nausea, irregular heartbeat, excessive
salivating
25. Negatives of drug
treatment
Drugs have to be
taken continuously
Have undesired side
effects
Really expensive to
keep taking
People may stop
taking them and their
symptoms reappear
Positives of drug
treatment
Addresses the patients
symptoms
Gives them their lives
back
26. Focuses on the idea that people can be
helped to understand their symptoms
It requires the individual to be able to
think rationally and logically. This may not
be possible with the presence of positive
symptoms
Talking about their symptoms may cause
them to relapse
27. Looks at changes in communication
patterns in the families of schizophrenics,
particularly with high EE
Main objectives are to :
› Get families to be more tolerant and less critical
› Help the family members feel less guilt
Tends to work well when conjoined with
other treatment
Therapy needs to be ongoing or there is a
chance of relapse
28. Aims to give the person continuous support
without having them go into hospital.
Emphasises case management – it tailors
the treatment for each individual so that
they are being cared for in the way in
which they need to be
The person is assigned a key worker –
usually a community psychiatric nurses
whose job it is to asses and co-ordinate
appropriate care
29. Hospitals can be seen as very stressful and can
exacerbate some symptoms
Hospitalisation does not equip the patients with
the skills that they need to function and live in
society
Community care gives the person their
independence back
Some people may slip through they cracks in
community care
Institutionalisation means that the person is in a
stable environment
Mental health care is very expensive
30. Requires thoughts and associated beliefs
to be challenged
It was though that attempting to modify
beliefs may strengthen them
Two important principals underpinning
the present approach are:
› Must start with the least important belief
› Work with the evidence for the belief and
not the belief itself
31. Usually involves verbal challenges i.e.
questioning the delusional interpretation
and puts forward a more reasonable one
By challenging evidence it leads to a
decrease in conviction. Also the person
become aware of the link between events,
beliefs, effect and behaviour
Reality testing involves planning and
performing activities that invalidates a
belief.
32. Chadwick et al (1996) – presented the
case of Nigel that claimed to be able to
tell what people were going to says
before the said it. The challenge this
belief video recorders were paused and
Nigel had to say what they were going
to say next. Out of 50 attempts Nigel
didn’t get one correct and concluded
that he did not have the power at all.
33. Kupiers et al (1997) found a 40%
reduction is the severity of psychotic
symptoms found through research trials
using cognitive therapy for delusions
Druary et al (1997) during a period of
acute psychosis, CBT led to a faster
response to treatment in a group of
patients compared to drugs.
