• Idea that thoughts are being controlled or broadcast
• Persecutory delusions
Catatonic behaviour (stupor):
• Social withdrawal
• Blunted emotions
What makes prescribing difficult with paranoid schizophrenic patients?
Lack of insight (knowledge or understanding that a disease is present)
How is dose decided with treatment for paranoid schizophrenics?
Start with minimum effective dose for 4-6 weeks then titrate up.
Use a single antipsychotic
What is monitored during antipsychotic treatment?
• Extrapyrimidal side effects (EPSEs)
• Weight, pulse, BP
• Glucose and lipid levels
When are glucose and lipid levels tested for patients undergoing antipsychotic treatment?
at 12 weeks and then annually
Which antipsychotic has the most evidence for effective use against schizophrenia?
What are the extrapyrimidal side effects?
Tremor at rest
What are the non-extrapyrimidal (normal) side effects of antipsychotics?
Weight gain & diabetes
Cardiovascular (Prolonging QT interval)
What are the causes of non response to antipsychotics?
Need to switch antipsychotic
What is depot medication and why is it used?
Injectable forms of slow release medication (that is usually also available as a tablet).
The idea is that in an injectable form, it only needs to be administered fortnightly (due to the slow release), so it can be used for antipsychotics to combat noncompliance long enough for the patient to gain insight into their condition.

If there is improvement continue treatment for another 4 weeks
How long must antipsychotic treatment be continued for and what is the risk if this isn't met?
2 years otherwise there is a risk of relapse
How long must antidepressant treatment be continued for?
