Insomnia and depression may arise from common genes

Sleepless nights may be genetically linked to depression, according to new research from the University of Pennsylvania and Virginia Commonwealth University. In a study of twins, researchers found that genetically identical twins who suffered from insomnia were significantly more likely than nonidentical twins to also suffer from depression. The two disorders have been linked before, but the role of genetics has not been clear. The new study indicates that insomnia and depression have overlapping genes, and the next step is to pinpoint those genes through DNA analysis. Possible contenders are the genes related to the neurotransmitters serotonin and norepinephrine, which are involved in both the sleep-wake cycle and mood regulation.

About Me

In its broadest sense, science (from the Latin scientia, meaning "knowledge") refers to any systematic knowledge or practice. In its more usual restricted sense, science refers to a system of acquiring knowledge based on scientific method, as well as to the organized body of knowledge gained through such research.

Fields of science are commonly classified along two major lines: natural sciences, which study natural phenomena (including biological life), and social sciences, which study human behavior and societies. These groupings are empirical sciences, which means the knowledge must be based on observable phenomena and capable of being experimented for its validity by other researchers working under the same conditions.
