Thyroid dysfunction can be a direct cause of depression.
Depression may be associated with the development of heart disease, stroke, diabetes, hypertension, hyperlipidemia, obesity, and autoimmune diseases such as multiple sclerosis or lupus. It also causes poor outcomes from these conditions.
Depression may increase the likelihood of smoking, drug or alcohol use, lack of physical activity, and lack of social contact with others.
Yes, women are two times more likely to experience depression than men, despite the country or culture that they live in. Reasons for this difference are thought to involve hormonal differences, the effects of childbirth, different psychosocial stressors for women and for men, and, for some women, behavioral models of learned helplessness.
No, there is no association between an increase in depression and a person’s age. The average age of onset for major depressive disorder is about 40 years, with 50 percent of all patients experiencing a major depressive disorder between the ages of 20 and 50. Recent data suggest that major depressive disorder may also be increasing among people younger than 20 years of age. This may be related to the increased use of alcohol and drugs in this age group.
The major depressive disorder occurs most often in individuals who have divorced or separated or those without close interpersonal relationships.
