Depression

Factors Predisposing towards Depression : Genetic make-up, or heredity is an important risk factor for major depression and other depressive disorders. Age is also a risk factor. For instance, women are particularly at risk during young adulthood, while for men the risk is highest in early middle age. Similarly gender also plays a great role in this differential risk addition. For example, women in comparison to men are more likely to report a depressive disorder. Other risk factors are experiencing negative life events and lack of social support.
