Introducing ‘Brainsplain’

189
I'm excited to be doing a new video project, called Brainsplain, in collaboration with MIA. In these videos, end-users of mental health resources critique the latest psychiatry research. I summarize new mental health investigations, and patients evaluate the significance. They share their hopes for future therapies and for changes to culture, and assess ethical issues raised by the research.

Different Forms of Childhood Adversity Related to Specific Psychosis Symptoms

In this month’s issue of Psychological Medicine, researchers from King’s College London found evidence for associations between different types of childhood adversity and specific symptoms associated with psychosis.

In a review article for this month’s American Journal of Psychiatry, Daniel Weinberger and Eugenia Radulescu from John Hopkins University push back against the overreliance on MRI scans in recent psychiatric studies.

Researchers from the City College of New York and Columbia University published a study this month testing the hypothesis that people diagnosed with schizophrenia treated long-term with antipsychotic drugs have worse outcomes than patients with no exposure to these drugs. They concluded that there is not a sufficient evidence base for the standard practice of long-term use of antipsychotic medications.

A massive number of meta-analyses of antidepressant clinical trials have financial conflicts of interest and are unduly influenced by pharmaceutical companies, according to a review to be published in an upcoming issue of the Journal of Clinical Epidemiology. Researchers also found that meta-analyses with industry ties almost never report any negative findings in their abstracts.
