1
Q

describe pharmacological treatment of schizophrenia

A
  • antipsychotics are the mainstay treatment (aka neuroleptics, major tranquilizers)
  • all are dopamine D2 receptor antagonists but some:
    • block DA2 receptors more potently
    • block additional types of DA receptors
2
Q

name examples of traditional antipsychotics

A
  • chlorpromazine and haloperidol
    • mechanism of action: DA2 antagonist
    • effect: improves positive symptoms
    • side effects: extrapyramidal syndrome (EPS) due to nigrostriatal DA2 blockade
3
Q

describe extrapyramidal syndrome (EPS)

A
  • dystonia: sustained muscle contractions (head, neck) often developing within the first week
  • parkinsonism: parkinsonian symptoms (tremor, shuffling) often developing in the first few months
  • akathisia: excessive movements due to “inner restlessness” often developing in the first few months
  • tardive dyskinesia: repetitive, involuntary, purposeless movements, often of the face and extremities, developing as a long-term (years) side effect
4
Q

describe neuroleptic malignant syndrome (NMS)

A
  • characterized by tachycardia, hypertension, rapid respiration, fever, extreme rigidity, delirium, death
    • usually occurs within first 2 weeks of starting medication or increasing dosage
    • likely due to a precipitous drop in DA affecting hypothalamic functioning
5
Q

describe atypical antipsychotics

A
  • examples:
    • clozaril (Clozapine): (1-2% agranulocytosis risk, decreased WBCs)
    • risperidone (Risperdal)
    • olanzapine (Zyprexa)
  • MoA: antagonists of DA2,3,4 and 5-HT receptors
  • effect: improves positive and negative symptoms
  • side effects: decreased risk of EPS
6
Q

describe supportive interventions to treat schizophrenia

A
  • vocational rehabilitation
  • individual psychotherapy
  • family education
7
Q

describe ECT augmentation in treating schizophrenia

A
  • ECT augmentation: used for medication-refractory schizophrenia (esp. catatonic type)
8
Q

describe schizophreniform disorder

A
  • at least 1 month of active-phase symptoms
  • signs of the disturbance last less than 6 months
9
Q

describe diagnostic criteria for brief psychotic disorder

A
  • at least 1 core psychotic domain symptom
    • delusions
    • hallucinations
    • disorganized speech
  • episodes last < 1 month
  • person returns to full premorbid functioning
  • specify “with marked stressor” or “without marked stressor” (based on trigger of episode)
10
Q
A
11
Q

describe diagnostic criteria for delusional disorder

A
  • the presence of a delusion
  • symptom must last ≥ 1 month
  • no other psychotic domain symptoms
  • no functional impairment aside from the direct impact of the delusion
12
Q

describe subtypes of delusional disorder

A
  • persecutory type: belief of malevolent treatment
  • grandiose type: belief of having some great (but unrecognized) talent or insight or important discovery
  • erotomanic type: belief of somebody being in love with the individual
  • jealous type: belief of infedility by partner
13
Q

describe the somatic type subtype of delusional disoder

A
  • somatic type (belief involving bodily functions/sensations):
    • parasitosis, malodorous, organ dysfunction
    • if delusion is appearance-related, then:
      • BDD with absent insight (delusional belief)
14
Q

contrast bizarre vs. non-bizarre delusion disorder

A
  • non-bizarre delusion: a belief that involves something that could occur in real life. the belief is physically possible
  • bizarre delusion: a belief that is clearly implausible and not derived from ordinary life experiences
15
Q

a delusion may develop in the context of a close relationship with a _____ indiudal

A
  • a delusion may develop in the context of a close relationship with a psychotic indiudal
  • the person believes the same delusion as the psychotic individual
  • treatment: antipsychotics, trial separation from partner, increasing sources of reality testing
16
Q

describe diagnostic criteria for schizoaffective disorder

A
  • active phase of schizophrenia occurs concurrently with a major mood episode (MDE or manic episode)
  • active phase lasts ≥ 2 weeks without mood symptoms
  • mood symptoms are present for “the majority of the total duration” of symptomatic periods of the illness
17
Q

describe the graph explaining schizoaffective disorder
