Brain structure may play key role in psychosis: study

PanARMENIAN.Net - New research finds that having a larger choroid plexus, which is a vital brain structure, could be involved in psychosis, Medical News Today reports.

Variations in the structure of the choroid plexus, which produces cerebrospinal fluid (CSF), could play a key role in psychosis.

A team that Dr. Paulo Lizano — of the Beth Israel Deaconess Medical Center in Boston, MA — led has now investigated this vital structure.

In doing so, they found that there could be a link between its size and the development of psychosis.

The choroid plexus and its product, CSF, are crucial parts of the neurological system. CSF helps cushion the brain within the skull, and the choroid plexus forms a barrier between the brain and the CFS, which helps filter out toxins and keeps blood components from entering the brain.

It also allows some molecules to pass through, including those involved with the immune system.

This study — which now appears in the American Journal of Psychiatry — involved three groups of people: participants with a diagnosis of psychosis, one of their first degree relatives, and people with no history of psychosis (the controls).
