Possible Link Discovered for Indicating Risks for Depression
Research headed by Columbia University College of Physicians and Surgeons has led to findings that suggest that thinning of the brain's cortex, in the right hemisphere of the brain, may be linked to hereditary or a " .... familial form of depression." The cortex is the outermost layer of the brain.
Individuals ages 6 through 54 years were followed for 25 years, with the study subjects being from families with and without a history of depression.
A 28% thinner cortex in subjects with family histories of depression was compared with those without the family history.
Mirror Resonance Imaging (MRI) images revealed structural differences between the brains of the offspring of depressed individuals that were not found in the offspring in families without mental illness.
