Paranoid = Preoccupation with one or more delusions (generally grandeur), Frequent auditory hallucinations, older onset,

Disorganized = Disorganized speech, behavior, flat/inappropriate affect, active, little contact with reality, doesn't meet criteria for Catatonic Type

Undifferentiated = Delusions, Hallucinations, Disorganization, Negative Symptoms, Doesn't meet criteria for paranoid, disorganized, catatonic

Residual = Absence of prominent delusions, hallucinations, disorganization, continuing evidence of disturbances: negative symptoms or presence of anove in attenuated form.

Front 11

What are the GOOD prognostic Predictors for Schizophrenia?

Back 11

Acute onset, brief duration of symptoms, later age at onset, no structural brain abnormalities, precipitating events, mood symptoms present, good premorbid functioning,

Front 12

What are the POOR Prognostic Predictors for Schizophrenia?

Back 12

Insideous onset, long duration of symptoms, younger age at onset, structural brain abnormalities present, Assaultiveness, mood symptoms absent, poor premorbid function, positive psychiatric history, Positive family Hx

Front 13

How is Schizophreniform different from Schizophrenia?

Back 13

Schizophreniform = same features are identical to Schizophrenia except:

Total duration of illness is at least 1 month but less than 6 months

Impaired social or occupational functioning is not required

Front 14

Define Schizoaffective Disorder

Back 14

Uninterrupted period of illness during which at some point there is Major Depressive Episode, Manic Episode or Mixed Episode concurrent with symptoms that meet Criteria A for Schizophrenia

During the same period of illness there have been delusions or hallucinations for at least 2 weeks in the absence of prominent mood symptoms

Front 15

Define Delusional Disorder

Back 15

Front 19

Define Shared Psychotic Disorder

Back 19

Delusion develops in an individual in the context of a close relationship with another person who has an already-established delusion

Front 20

Back 20

Yep

Front 21

Criteria for mood disorder due to general medical condition

Back 21

Prominent hallucinations or Delusions

Evidence that disturbance is the direct physiological consequence of a GMC (not better-accounted for and doesn't occur exclusively during a delirium)

Front 22

Define Substance-induced Psychotic Disorder

Back 22

Prominent Hallucinations or Delusions

Evidence that they develop during or within a month of Substance Intoxication or Withdrawal - Med use is etiologically related to the disturbance (not better accounted for by a psychotic disorder that is not substance-induced)

Doesn't occur exclusively during a delirium

Front 23

Define Psychotic disorder NOS

Back 23

Psychotic Symptomology for which there is inadequate info to make specific Dx or about which there is contradictory info, or disorders with psychotic symptoms that do not meet the criteria for any specific Psychotic disorders

Front 24

Examples of Psychotic Disorder NOS - Just read

Back 24

Post-partum psychosis that doesn't meet criteria for others

Psychotic symptoms lasting less than 1 month

Persistent auditory Hallucinations in the absence of any other features

Persistent non-bizarre delusions with periods of over-lapping mood episodes that have been present for a substantial portion of the delusional disturbance

Situations in which clinician has concluded that a psychotic disorder is present but is unable to determine whether its primary, due to GMC, or Substance-induced

These flashcards contain too much info to be useful but oh well :)
