In a first-of-its-kind study using advanced brain imaging techniques, a commonly used antipsychotic medication was associated with potentially adverse changes in brain structure. This study was the first in humans to evaluate the effects of this type of medication on the brain using a gold-standard design: a double-blind, randomized, placebo-controlled trial.
The study, conducted across several North American centers, and just published in the journal JAMA Psychiatry, could have an immediate impact on clinical practice according to lead author Dr. Aristotle Voineskos, Chief of the Schizophrenia Division, and Head of the Kimel Family Translational Imaging-Genetics Laboratory at the Centre for Addiction and Mental Health (CAMH) in Toronto, Canada.
Until the 1990s, antipsychotic medications were primarily administered to people with schizophrenia. But since then their use has expanded to major depression and a range of pediatric, adult and geriatric disorders, including anxiety, insomnia and autism, for which one in five patients are prescribed anti-psychotics.
