Depression - Warning Signs

There are two popularly held explanations for the feelings of sad­ness, withdrawal, or lethargy characteristic of depression. Both explanations have to do with the levels of neurotransmitters or chemical messengers in the brain. One theory attributes depression to a low level of one such messenger, called serotonin, and the other to a low level of another, called norepinephrine. Almost all the drugs psychi­atrists use to treat depression increase the levels of one or both of these chemicals.

Deficiencies of vitamins B1, B6 , C, and A, folic acid, niacin, copper, magnesium, and iron can all cause depression by affecting Sheraton and norepinephrine metabolism. Brain levels of norepinephrine can be raised by taking supplements of tyrosine and phenylalanine, since they are converted into norepinephrine in the brain. The same is true of tryptophan, which makes serotonin and so can raise its brain levels when you get enough of it into your body. Both tyrosine and tryp­tophan have been shown to be useful in the treatment of unipolar depression, a condition that causes the patient to swing from a nor­mal, well-adjusted mood to a period of withdrawal, sadness, and lethargy. However, these substances are of no value in treating bipolar depression, in which mood swings range from irrational elation to total depression.
