- Bio Treatments
- All antipsychotic drugs block out neurotransmitters
- Conventional anti psy
- primarily used to combat the positive symptoms- products of overactive dop system
- drugs reduce dop so reduce SZ. They bind to dop receptors to stop stimulation = block action
- By reducing dop = elimination hallucinations etc...

- Revolutionised treatment for psychotic patients, 65% benefit from medication
- Davis et al reviewed 29 studies compared placebo relapse rates 55% compared to 19%
- Take several weeks to work
- Not so effective in treating neg symptoms
- diff causes ie. large ventricles and loss brain cells
- If start drug should remain because body adapted
- Multiple side effects ie tardive dyskinesia (writhering) no longer 1st option
- primarily used to combat the positive symptoms- products of overactive dop system
- Atypical drugs ie. clozapine
- also act on dop patjhway temp occupy d2 dop receptors and then rapidly dissociate to allow normal dop transmission
- characteristic that is thought to have lower side effects than conventional ones
- 1990 effective 85%
- Better at treating neg symptoms
- fewer side effects
- still risk side effects ie 1/2% develop fatal whit blood cell condition
- Leucht meta analysis atypical + typical only 'slightly' more effective
- also act on dop patjhway temp occupy d2 dop receptors and then rapidly dissociate to allow normal dop transmission
- Appropriateness of anti psychotics
- 30% taking conventional anti develop TD irreversibly 75% of cases
- Few side effects of atypical = more stay on drugs
- Ross + Read prescribed med reinforces 'something is wrong with them' which reduces look at other sources ie life stress
- 3rd generation
- 76 drugs in development each one targets specific set of receptors ie. d1 d2
- every ind diff abnormality and we can't see what that abnormaility is
- Overall Eval Drug treatment
- good
- more effective any other treatment = strong bio cause
- works quicker psy therapies
- allows patient live normal lives
- best along other reduces relapse
- bad
- Ethical. should drugs be taken without consent?
- Researcher bias funded by drug companies
- good
- ECT
- restricted certain forms of SZ ie. catatonic/ haven't responded other treatments
- Catatonic respond ECT = rapid alleviation of symptoms
- Thyryan + Adams review 26 studies 800 patients. 'Placebo condition'. More people improved real ECT no indication LT benefit
- When ECT is compared with antipsy drug = improvement mental state
- Risk: death, memory loss rarely used
