Seasonal Affective Disorder (SAD)
Seasonal Affective Disorder (SAD) is characterized by periods of depression that coincide with seasonal changes during the year. It is most often noted in late fall and winter, alternating with periods of normal or high mood the rest of the year. Seasonal Affective Disorder is also called Seasonal Depression, and it is more than just a case of the winter blues or the cabin fever that can occur when a person stays indoors in the winter for long periods because of cold or accumulated snow. A rare form of SAD known as ‘Summer Depression’ begins in late spring or early summer and ends in the fall. Most SAD patients are adult women, although adult men, children and adolescents also report symptoms of this disorder. It is believed that SAD is caused by a biochemical imbalance in the hypothalamus that occurs as a result of shorter periods of daylight in winter. However, it is clear that more research is required to determine the cause(s) of SAD. A family history of depressive disorders and a high coincidence of other disorders in SAD patients may indicate more complex causal relationships. For example, atypical depressive symptoms of hypersomnia, hyperphagia, and weight gain occur more often in SAD patients as compared to patients that do not suffer from seasonal disorders.
Whatever the cause(s), SAD can be a disabling illness, preventing normal function in patients. It can result in debilitating depression, weight gain, increased sleep, decreased activity and a loss of interest in sex. In patients who suffer from the ‘winter blues’, symptoms are much less debilitating and typically do not require treatment. SAD patients seem to generate a biological signal of seasonal change that is absent in people who do not have SAD. The signal is similar to the one used to regulate changes in mammalian seasonal behavior. These patients also exhibit an increased release of Melatonin during the course of this seasonal disorder. Melatonin is a naturally occurring hormone secreted by the pineal gland in the brain, and it regulates the internal body clock.
What are the symptoms?
The average annual onset of SAD symptoms begins in October or November and subsides in March or April, though some patients may begin to feel the effects as early as August, and some do not exhibit symptoms until January. Some patients begin to slump as early as August, while others remain well until January.
How is it diagnosed and treated?
Doctors will perform a full medical and mental evaluation to rule out other disease or illness and the coincidence of other disorders that may also require treatment. SAD is often misdiagnosed as hypothyroidism, hypoglycemia, infectious mononucleosis, and other viral infections.
Diagnostic criteria can include the following:

The Warning Signs Of An Impending Bipolar Disorder Manic Episode
Bipolar disorder - as the name implies - involves two distinct set of symptoms. One set throws the individual down into the depths of a massive depression. The other places the individual who suffers with bipolar disorder at the top of a peak manic episode.
Most everyone can eventually recognize the warning signs of an impending depressive episode related to bipolar disorder. More likely than not, individuals with bipolar disorder try very hard to avoid it.
However, for many individuals with bipolar disorder, it's more difficult to recognize the signs of an impending manic episode. After all, a manic episode of bipolar disorder can be mistaken in some cases - especially in the very early formation -- for the lifting of the corresponding mood swing of the depression.
