An increasing number of older adults with dementia are being prescribed antipsychotic drugs to regulate their behaviour; something that has been linked with Parkinson's-like symptoms, stroke and diabetes. Researchers from the University of Toronto studied 13,817 people with diabetes who started treatment with antipsychotics between 2002 and 2006. 11% were hospitalized for hyperglycaemia (high blood sugar) over the course of the study. Those who were currently taking antipsychotics had a higher risk of hospitalization and the risk was highest among those who were just starting antipsychotic treatment. Some previous studies have suggested that the neurotransmitter dopamine has a role in regulating blood sugar so it could be the antipsychotic's effects on dopamine within the body that leads to the increased risk.
