Having depression for a long period of time is not a normal part of growing older. Most older adults feel satisfied with their lives, despite having more illnesses or physical problems. But depression in older
adults may be difficult to recognize because they may show different, less obvious symptoms.
Sometimes older people who are depressed appear to feel tired, have trouble sleeping, or seem grumpy and irritable. Confusion or attention problems caused by depression can sometimes look like Alzheimer’s
disease or other brain disorders.
Older adults also may have more medical conditions such as heart disease, stroke, or cancer, which may cause depressive symptoms. Or they may be taking medications with side effects that contribute to depression.
Some older adults may experience what doctors call vascular depression, also called arteriosclerotic depression or subcortical ischemic depression. Vascular depression may result when blood vessels become less flexible and harden over time, becoming constricted.
The hardening of vessels prevents normal blood flow to the body’s organs, including the brain. Those with vascular depression may have or be at risk for heart disease or stroke.
Sometimes it can be difficult to distinguish grief from major depression. Grief after loss of a loved one is a normal reaction and generally does not require professional mental health treatment. However, grief that is complicated and lasts for a very long time following a loss may require treatment.
Older adults who had depression when they were younger are more at risk for developing depression in late life than those who did not have the illness earlier in life.
