Depression Related Diseases
There are varying types and degrees of depression. Mild depression is known as dysthymia. Unlike clinical or major depression, mild depression is not necessarily disabling, but it does keep a person from functioning normally and interferes with their social interactions and enjoyment of life. Dysthymia is diagnosed when the patient has been depressed for most of the time for at least two years (one year for children or adolescents) and has at least three of the following symptoms: low self-esteem or lack of self-confidence, anxiety, variable moods, fits of crying for no apparent reason, pessimism, hopelessness or despair, lack of interest in ordinary pleasures and activities, withdrawal from social activities, fatigue or lethargy, guilt or ruminating about the past, irritability or excessive anger, lessened productivity, and difficulty concentrating or making decisions.
Another type of depression is called seasonal affective disorder. Seasonal affective disorder occurs when a person becomes more depressed during the winter months and suffers a loss of energy, anxiety attacks, weight gain, excessive sleep, and a reduced sex drive. This disease is more common in women than in men.
The most severe and the most rare type of depression (affecting only about eight per 1,000 people) is called manic depression. This form of depression is equally common among men and women and can consist of depression and/or mania.
Depression can also lead into other diseases and disorders. For example, depression is often a first or early manifestation of thyroid disease. Stress can cause the adrenal glands to malfunction, elevating cortisol levels and decreasing DHEA levels in the glands. These abnormal cortisol levels can cause depression, mania, nervousness, insomnia and sometimes even schizophrenia.
