Depression in the Elderly

We all have our down days.  We may have accepted that it is healthy to express our feelings and to take medication for depression if necessary.  People in their 70's and 80's may not be as open about sharing their feelings or taking more pills than they already do.
The elderly manifest symptoms of depression differently than younger people.  They often get a lethargic ("I'm not worthy of anything") type of depression.  There may be some somatic complaints, withdrawal and apathy. The inability to concentrate and loss of self-esteem are prominent.  Many elderly and their family members just accept these feelings as part of aging. 
Biochemical changes may contribute to depression, the production of dopamine and serotonin may be decreased.  This is why antidepressants can work so well in the elderly, by adding more of neurotransmitters.
So what can you do to help?  Encourage outings and social functions.  A friend can make a huge difference in how someone views their life.  If possible, get them outside to exercise, walking even for a short time can help.  If you feel this person is clinically depressed, maybe it's time to encourage a visit to their GP or a mental health professional.  They also might need to be screened for symptoms of dementia.  A kind doctor who has experience with the elderly can be very helpful in taking away the stigma of mental illness.
