[3] In their lifetime, 20% to 25% of women and 7% to 12% of men will have a major depressive episode. [35] The peak period of development is between the ages of 25 ...
Vitamin D deficiency: Usually asymptomatic, causes reduce bone density (osteomalacia), rickets, myopathy, and is associated with the development of schizophrenia. It is typically diagnosed by measuring the concentration of the 25-hydroxyvitamin D (25(OH)D) in plasma, which is the most accurate measure of stores of vitamin D in the body ...
Winter depression is a common slump in the mood of some inhabitants of most of the Nordic countries. Iceland, however, seems to be an exception.
