A recent study has found that genetics could be used to predict a patient's response to antipsychotic drug treatment for schizophrenia. According to the ANI report the findings of The Feinstein Institute for Medical Research were published in the American Journal of Psychiatry. Schizophrenia is characterised by delusions hallucinations and disorganised thoughts and behaviour. The condition is currently treated with antipsychotic drugs but this therapy is given without guidance from lab tests to show effectiveness as is common in other areas of medicine. Doctors often use trial-and-error when choosing a treatment for schizophrenia without knowing if patients will respond well.
