Washington, Jun 11 (Prensa Latina) A neurochemical deficiency may be linked to primary insomnia (PI) in adults it was reported today.

According to researchers of the Harvard Medical School gamma-amino-butiric (GABA) acid, the main inhibitor neuro transmissor in the brain is reduced 30 percent in persons who suffer primary insomnia for more than six months.

Recognizing that primary insomnia is associated to a specific neuro chemical deficiency aids a better understanding of sleep disorder, explained the main author of the study, John Winkelman.
