According to the American Geriatrics Society 40% of nursing home residents are affected by depression, yet depression often goes undiagnosed or un-treated in elders living in long term care facilities.
Depression is the No. 1 under-treated illness in the geriatric population. Unlike the profile of other diseases that cluster with aging, depression does not show up on lab tests, or EKGs. It is often masked by other chronic illnesses and can mimic dementia. These and many other reasons make depression in the elderly a difficult challenge.
