[Geriatric psychiatry--relevance for the general practitioner]

The older population, the group of the very old in particular, is increasing and thus the risk group for the two most important psychiatric disorders, dementia and depression. Many individuals become mentally ill for the first time late in life, mainly because of losses, loneliness and somatic diseases. Therefore, beside physical examination, screening for depression and cognitive testing are very important for the general practitioner. Relatives and caregivers often play a keyrole. They have to be involved in evaluation and therapy and their needs for support and advice should be considered.
