Lecture 12 Flashcards
Schizophrenia
association between socioeconomic status and schizophrenia
low SES induces stress –> vulnerability to physiology
low SES are discriminated –> vulnerability to labeling (highly stigmatizing)
downward drift –> DOs dysfunctions cause SES to drop (loss of status, job, etc.)
core negative, positive, and psychomotor symptoms of schizophrenia
negative:
blunt emotions
alogia
loss of volition/motivation
withdrawal from social environment
positive:
distorted thoughts and speech
heightened perceptions
delusions and hallucinations
inappropriate affect
psychomotor:
catatonia
motor retardation
schizophrenia vs schizoaffective DO
schizophrenia: major mood disorder, severe dysfunction
schizoaffective: severe dysfunction not required
dopamine hypothesis of schizophrenia
excess amount of dopamine in the brain
treatment for parkinson’s increased positive symptoms of schizophrenia
antipsychotic meds reduce dopamine
brain structure abnormalities associated with schizophrenia
enlarged ventricles: brain cavities filled with csf, poor development, and damage in the brain
small temporal and frontal lobes: decreased amounts of gray matter and abnormal blood flow in the brain
common side effects of typical antipsychotics
affect extra pyramidal areas of brain
parkinsonian symptoms:
muscle tremor and rigidity
bizzare movements of face, neck, tongue, and back
great restlessness, agitation, and discomfort in the limbs
neuroleptic malignant syndrome:
improper functioning of autonomic nervous system
can be fatal
tardive dyskinesia:
writhing or tic-like involuntary movements
main advantages of atypical antipsychotics
more effective, esp for negative symptoms
fewer movement effects
