* atypic;

antipsychotics

* inhibitory effect

typical antipsyhtocis

* first generation
* chlorpromazine is favoured
* calming and sedative

atypical antipsychotics

* adds to the first gen
* alleviate side effects of first genetic
* they also target other receptors,
* clozapine serotonin

strength of clozapine

* improve cog fucntioning
* mood

list ao3

* based on dopa hypothesis
* side effects
* studies suffer from validity

based on dopamine hypothesis

* antipyshtoics help reduce dopa
* make sense
* but revised theory, low leevls
* sp reduction in dopamine makes symptoms worse

\

side effects

* short term-agitation and weight gain
* long term- involuntary muscle contraction
* neuroleptic malignant syndrome
* cost benefit anayaliss whether it benefits truly

studies suffer from validity

* Chlorpromazine powerful sedative effects
* supressing symptoms doesn’t control them
* studies not actually measuring the effects of antipsychotics
* don’t focus on long term risks
* withdrawal symptoms
