Today’s headlines are packed with reports of a Jet Blue pilot who “flipped out” and went “berserk.” If he had had a heart attack during the flight, I’m sure he would have gotten some sympathy. Instead, reporters are talking about charges that may be filed against the pilot.
In a study just published on PLoS One entitled “Lithium Impacts on the Amplitude and Period of the Molecular Circadian Clockwork,” researchers at the University of Manchester (Jian Li, Wei-Qun Lu, Stephen Beesley, Andrew S. I. Loudon, and Qing-Jun Meng) have discovered that lithium works as a pacemaker for the circadian clock, which may help to explain lithium’s mechanism of action – how it works.
Research has long shown an association between low folate levels and depression, particularly depression that’s more severe and less responsive to medical treatment. (Folate is a water-soluble B vitamin in its natural form. Folic acid is the synthetic version found in supplements.)
Folate is critical in the development of the human nervous system, so pregnant women must take folic acid supplements. People who abuse alcohol, people with certain illnesses, and those who take a number of different medications are at risk for folate deficiencies, which can present with a variety of cognitive, emotional, and behavioral symptoms. Doctors may check folate levels as part of an initial workup of depression.
