Changes in nerve cells may contribute to the development of mental illness
Reduced production of myelin, a type of protective nerve fiber that is lost in diseases like multiple sclerosis, may also play a role in the development of mental illness, according to researchers at the Graduate School of Biomedical Sciences at Mount Sinai School of Medicine. The study is published in the journal Nature Neuroscience.
Myelin is an insulating material that wraps around the axon, the threadlike part of a nerve cell through which the cell sends impulses to other nerve cells. New myelin is produced by nerve cells called oligodendrocytes both during development and in adulthood to repair damage in the brain of people with diseases such as multiple sclerosis (MS).
A new study led by Patrizia Casaccia, MD, PhD, Professor of Neuroscience, Genetics and Genomics; and Neurology at Mount Sinai, determined that depriving mice of social contact reduced myelin production, demonstrating that the formation of new oligodendrocytes is affected by environmental changes. This research provides further support to earlier evidence of abnormal myelin in a wide range of psychiatric disorders, including autism, anxiety, schizophrenia and depression....
