Losing sleep, losing brain?
Date:1/27/2010

Philadelphia, PA, 27 January 2010 - Chronic and severely stressful situations, like those connected to depression and posttraumatic stress disorder, have been associated with smaller volumes in "stress sensitive" brain regions, such as the cingulate region of the cerebral cortex and the hippocampus, a brain region involved in memory formation. A new study, published by Elsevier in Biological Psychiatry, suggests that chronic insomnia may be another condition associated with reduced cortical volume.

Using a specialized technique called voxel-based morphometry, Ellemarije Altena and Ysbrand van der Werf from the research group of Eus van Someren evaluated the brain volumes of persons with chronic insomnia who were otherwise psychiatrically healthy, and compared them to healthy persons without sleep problems. They found that insomnia patients had a smaller volume of gray matter in the left orbitofrontal cortex, which was strongly correlated with their subjective severity of insomnia.

"We show, for the first time, that insomnia patients have lower grey matter density in brain regions involved in the evaluation of the pleasantness of stimuli, as well as in regions related to the brain's 'resting state'. The more severe the sleeping problems of insomniacs, the less grey matter density they have in the region involved in pleasantness evaluation, which may also be important for the recognition of optimal comfort to fall asleep," explained Altena. She added, "Our group previously showed that insomniacs have difficulties with recognizing optimal comfort. These findings urge further investigation into the definition of subtypes of insomnia and their causal factors, for which we have now initiated the Netherlands Sleep Registry."

Dr. John Krystal, Editor of Biological Psychiatry, commented, that "insomnia is a common feature of nearly every psychiatric condition associated with reduced cortical volume; in fact, it is a common symptom of psyc
