Sleeping too little or too much, abnormal breathing during sleep, and excessive daytime sleepiness all were significantly associated with cognitive impairment — years later in some cases.

In a cross-sectional study of more than 1,200 cognitively normal individuals older than 65, omega-3 fatty acid intake was significantly predictive of plasma levels of the 40- and 42-residue forms of beta-amyloid protein (AB40 and AB42, respectively), according to Nikolaos Scarmeas, MD, of Columbia University in New York City, and colleagues.
