Despite growing evidence of side effects antipsychotic drugs (originally developed to deal with the symptoms of schizophrenia, psychois and bipolar disorder) are still prescribed to older people without these conditions. The American company Prescription Solutions studied 78,450 elderly people. None of them had schizophrenia, bipolar disorder or diabetes at the start of the study. The participants were followed for a five-year period over which time 13,075 developed diabetes. The study showed that the participants who had received at least one prescription for an antipsychotic drug had a 32% greater chance of developing diabetes.
