Having taken Seroquel (quetiapine) myself it was concerning to see the headlines "Antipsychotic drug 'stroke risk'" and "Antipsychotic drugs double stroke risk: study" on the BBC and Reuters web sites. British researchers are reporting (published in British Medical Journal) that you are nearly twice as likely to have a stroke taking antipsychotic medication compared to those not taking it and the chances of a stroke increase to 3.5 times for patients with dementia.
This study is concerning and hopefully the finding will lead to more research in this area. For most of us, I guess things are so bad when prescribed antipsychotics that the risks associated with not taking the medication are greater but it is good that this type of study is available for us so that we are better informed of the risks.
