Thought content (3 possible components)
Hallucinations: whispering, conversing, commanding Delusions: paranoid, religious, grandiose, ideas of reference, thought broadcasting/insertion Suicidal & Homicidal ideation: document plan & intent, if pt denies SI/HI but has command hallucination to harm self/others, document & address it!
26
Another component of MSE
Insight & Judgment
27
Schizophrenia: factors indicating more positive prognosis
- Female - Later onset - Acute onset w/precipitating factor - Brief duration, early intervention, tx compliance - Positive symptoms - mood disturbance, family hx of mood do - high SES, married, good support system - good premorbid functioning
28
Schizophreniform Disorder
- Essential features identical to Schizophrenia (delusions, hallucinations, disorganization, neg sxs) - SHORTER duration: 1-6 months - social/occupational fxn may/may not be impaired
29

4 types of delusions which can be one of which 2 things
-paranoid or persecutory -grandiose -reference -somatic BIZARRE vs. NON-BIZARRE
37
Delusional disorder: prevalence, demographics
* prevalence=0.03%, males=females, but variation among subtypes * variable age at onset (teen-late adulthood) * variable course (may remit & relapse) * possible familial relationship to Schizophrenia
38
Non-bizzare delusions

54
Acute stabilization of psychotic d/os: medication
start antipsychotic at low dose & titrate as needed, avoid using 2 antipsychotics
55
Acute stabilization of psychotic d/o: priority, sxs
``` priority=safety, ↓ DTO/DTS may need hospitalization agitation improves fast(min-hrs) hallucinations improve in days negative sxs, delusions, cognitive deficits take much longer, if they improve ```
56
Indications for hospitalization in psychotic d/os (4)

57
Maintenance of psychotic d/os goal
symptom control and relapse prevention
58
Maintenance of psychotic d/os
compliance is an issue - simplify med regimen (daily vs BID/TID dosing) - minimize SEs * day/partial hospitalization or intensive outpatient programs * assertive community tx, case management * involve social network
59
