[Psychotic Disorders]
1. Delusions and types
2. Illusions vs hallucinations and types

1. Delusions - fixed, false beliefs against cultural norms and despite evidence to the contrary
- persecutory - most common
- ideas of reference - external stimuli perceived as personal (Eg actor on TV winking at you)
- delusions of control -- thought broadcasting, thought insertion
- delusions of grandeur - special powers
- delusions of guilt
- somatic delusions - disease or illness

2. Illusions vs hallucinations
A. Illusions - misinterpretation of existing stimulus
B. Hallucinations- sensory perception without existing stimulus
- auditory - schizo
- visual - delirium, drugs, alcohol withdrawal
- olfactory - epilepsy
- tactile - drug use, alcohol withdrawal


[Psychotic Disorders]
1. Types of symptoms
2. Criteria for diagnosis

1. Types of symptoms
A. Positive
- delusions
- hallucinations
- disorganized speech e.g. looseness of association, clanging, flight of idea, neologisms
- disorganized behavior e.g. catatonia

B. Negative *most impairment to QOL, most difficult to treat
- apathy / avolition
- anhedonia
- affect (flat)
- alogia
- attention - decreased

C. Cognitive - decreased executive function and working memory
- decreased size of hippocampus and amygdala

2. Criteria for diagnosis - 2+ symptoms (1 must be either delusions, hallucinations, or disorganized speech) for >1 months
- total duration >6 months
- course includes prodromal (decreased functioning), psychotic, and residual (more neg sx)


[Psychotic Disorders]
3. Pathophysiology via tracts (mesolimbic, mesocotical, nigrostriatal, tubuloinfundibular) and neurotransmitters
4. CT scans

3. Pathophysiology
- ↑ dopamine in mesolimbic tract --> psychotic sx
- ↓ dopamine in mesocortical tract (frontal cortex) --> negative sx, poor cognition
- nigrostriatal tract - blocked by antipsychotics --> EPS
- tubuloinfundibular tract - blocked by antipsychotics esp typicals and risperidone --> hyperprolactinemia --> gynecomastia, galactorrhea, sexual dysfunction, menstrual irregularities

- also ↑ serotonin (atypicals also antagonize 5HT)
- ↑ norepi (long-term antipsychotic use decreases norepi levels)
- ↓ GABA (which has regulatory effect on dopamine) in hippocampus
- ↓ glutamate - fewer NMDA receptors *why ketamine (NMDA antagonist) causes psych sx

4. CT shows enlarged ventricles, cortical atrophy, and decreased brain volume


[Psychotic Disorders]
5. Compare contrast with schizophreniform disorder, brief psychotic disorder

Schizophreniform - symptoms between 1 and 6 months
- 1/3 recover, 2/3 progress to schizophrenia or schizoaffective
tx - 6 months course of antipsychotics, supportive psychotherapy

Brief psychotic disorder - symptoms between 1 day and 1 month, eventual full return to level of functioning
- positive symptoms only (delusions, hallucinations, disorganized speech/ behavior)
- tx - antipsychotics, benzos, supportive psychotherapy

*borderline personality may have transient, stress-related psychotic symptoms but this is not brief psychotic disorder, it's attributed to their underlying personality disorder


[Psychotic Disorders]

2. Types
3. Treatment

Delusional disorder - more common after age 40

- grandiose
- somatic
- persecutory *most common
- jealous
- mixed
- unspecified

3. Treatment - difficult to treat given lack of insight and impairment
- antipsychotics
- supportive therapy but NO groups

1. Koro
2. Amok
3. Brain fag

2. Amok - sudden, unprovoked outbursts violence followed by suicide - in malaysia

3. Brain fag - headache, eye pain, fatigue, cognitive difficulties in male students - in Africa


[Psychotic Disorders]
Differentiate mood disorder with psychotic features from schizoaffective disorder

Schizoaffective - meet criteria for either major depressive or manic episode during which psychotic symptoms are also present
- but also - delusions or hallucinations for 2 weeks in absence of mood disorder symptoms
- mood sx present for majority of psychotic illness

Mood disorder with psychotic features -- better prognosis, hallucinations and/or delusions present ONLY during depressive or manic episodes
- usually mood congruent e.g. depression --> paranoia, mania --> grandiosity, invincibility
- treat MDD w psychosis --> antidepressant and antipsychotic or ECT
*remember that bipolar I may have psychotic features that occur during depressive OR manic episodes


[Mood Disorders]
1. Depressive episode criteria
2. Manic criteria
3. Hypomanic criteria
4. Mixed features

- anhedonia (loss of interest) + 4 add'l SIGECAPS
SIGECAPS: sleep, interest, guilt/worthlessness, energy/fatigue, concentration, appetite, psychomotor activity (restlessness or slowness), SI

2. Manic criteria - at least 3 symptoms for 1+ week or until hospitalized
- abnormally elevated or irritable mood (if irritable, need 4 symptoms)
DIGFAST - distractibility, insomnia/impulsive behavior, grandiosity, flight of ideas/racing thoughts, activity/agitation, speech (pressured), thoughtlessness
*50% have psychotic features

3. Hypomanic criteria - no marked impairment in functioning *only psych disorder where this is true*
- no psychotic features
- at least 3 symptoms for 4+ days (4 sx if mood is irritable)

4. Mixed features - meet criteria for manic or hypomanic episode and 3+ symptoms of major depressive episode are present for 1+ week
- predominant mood state is irritability
* poorer response to lithium --> give valproic acid

4. Tardive dyskinesia - (months to years of prolonged therapy, can also appear following dose discontinuation or reduction)
- due to D2 receptor upregulation and supersensitivity following chronic blockade
- irreversible, no definitive treatment, but switch to clozapine may help (least likely to cause EPS), along with Vitamin E or botox
