Wealth of evidence to support the use of drugs in treatment - Davis et al (1980) analysed results from 29 studies and found relapse occurs in 55% of patients whose medication was replaced with placebo but was significantly less in those who remained on drug
Ross & Read (2004) - these results show 45% of those given placebo had no relapse and did well without drugs, suggesting they weren't needed - also argued that being given drugs reinforced that there is "something wrong with you" - prevents individuals looking for causes that can be fixed and thinking medication is only option
Also, despite some people seeing bigger benefits using atypical antipsychotics compared to conventional, a meta-analysis of studies revealed that the superiority of the drugs was only moderate - however atypical drugs still have less risk of side effects
Conventional anrtipsychotics - uncontrollable movements in 30% of ases, 75% are irreversable according to Hill (1986) - effects are lower in atypical
Jeste et al (1999) found movements happen in 30% taking conventional drugs and just 5% taking atypical - fewer side effects means patients more likely to take medication and help schizophrenia
