Chronoscopic reading in whole body reaction times in detecting cognitive dysfunction in metabolic syndrome: a case control study.

Background: The metabolic syndrome, a clustering of several commonly occurring disorders that include abdominal obesity, hypertriglyceridemia, low high-density lipoprotein level, hypertension, and hyperglycemia, has been specifically investigated as a risk factor for cognitive decline in elderly individuals. The metabolic syndrome may be a risk factor for cognitive decline because it summarizes the joint effects of these risk factors. It is known that difference between simple and choice reaction time (RT) implies time required for cognition.
