  • Biological Treatments for Schizophrenia (Sz) AO3
    • Effectiveness of drug treatment - from the different annotations highlight using the correct colours the PEEEEL
      • There is a collection of supportive research evidence for both typical and atypical drugs in the treatment of Sz
      • As both drugs are regarded as having a moderate effect in tackling the symptoms of SZ
      • A review of research, sample total of 1121, showed that Pps who received Chlorpromazine compared to a placebo. Showed better overall function and reduced severity of their symptoms. As well as Clozapine was seen to be 30-50% effective where typical antipsychotic drugs have failed.
      • The reviews both indicate that by using these drugs have a positive effect from reducing the symptoms or working when other drugs have failed.
      • Their is further research evidence data from 3 trials showed that relapse rates were reduced when Chlorpromazine was taken
      • This clearly shows that both typical and atypical drugs are generally effective in treating Sz.
    • A key problem with using drug therapy in the treatment of Sz is side effects.
      • What side effects are associated to Typical antipsychotics?
        • What can long term use cause and explain how this affects a person's behaviour.
        • What is the most serious side effect? Explain how this is caused.
      • Explain why Atypical Antipsychotics were developed.
        • What are the side effect from typing this type of drug?
    • There is clearly evidence to support the effectiveness of Antipsychotic drugs in the treatment of Sz; however there are problems with evidence used, explain.
    • The dopamine hypothesis plays a role in the use of antipsychotic drugs, explain what role it plays and why.
