Depression is not a normal response to the aging process (It is a disease). It is very common problem in elderly with 25% of patients at primary care report depressive symptoms.
Effects of depression
Depression is associated with poorer self-care and slower recovery after acute medical illnesses.
It can accelerate cognitive and physical decline and leads to an increased use and cost of health care services.
Less effective rehabilitation
Lower quality of life, higher level of chronic pain, and increased disability (is the fourth leading cause of disability in the United States).
The mortality rate coincided with the level of depression even when controlling for other factors.
Types of depression
Primary depression is not triggered by any other psychological or medical cause. Rather, this type of depression is triggered by psychological instability, genetic predisposition.
Secondary depression is caused by one or more negative life events such as illness, this kind of depression is triggered by a medical condition as thyroid gland disorder and by a psychiatric illness as schizophrenia.
Symptoms of depression and how old age can modify its presentation?
1. Depressed mood and/or lack of interest or pleasure in usual activities
The older adults may be more likely to express a loss of pleasure than to specifically complain of depression
2. Feelings of worthlessness or inappropriate guilt
Less common in older adults than in younger adults
3. Diminished ability to concentrate or make decisions
Often manifested as a complaint of memory problems—adults of all ages with moderate-to-severe depression complain of problems with concentration and memory, but depressed elders, in contrast to younger adults, exhibit impairment on psychological testing even when they do not have a comorbid dementing disorder
4. Fatigue Common regardless of age
5. Psychomotor agitation or retardation
Older persons may exhibit either of these symptoms
6. Insomnia or hypersomnia
Older persons rarely, if ever, exhibit hypersomnia—a symptom that is much more common in adolescence and young adults
7. Significant decrease or increase in weight or appetite
Older adults rarely gain weight or experience an increase in appetite during a depressive episode
8. Recurrent thoughts of death or suicidal ideation
Although thoughts of death are not uncommon in older adults, suicidal ideation among depressed elders is less frequent than among the depressed who are younger but more risky.
9. More likely to express somatic complaints
65% have hypochondriacal symptoms
