Aetiology
Depression in old age is the result of a large number of factors. These include biological, psychological, social, spiritual, and personality factors:
- loneliness, for example following bereavement, or because of less social contact. This scenario also adds to the development of metabolic syndrome, leading to increased cortisol and hypothalamic-pituitary-adrenal dysregulation, another major reason for the development of depression. (1)
- poor physical health, particularly where this is disabling or leads to a loss of independence. Common examples include visual or auditory impairment, osteoarthritis.
- precipitation by life events - note that after a bereavement up to 20% are clinically depressed for a year
- depression is more common amongst elderly women than men
- may occur as a side-effect of certain drugs
