[Psychiatric and neurological problems of the older age (author's transl)]

Pyschical crisis and pathological change do not differ at people in the older age. The two terms do not characterize the normal development of the old age, but extreme spheres are circumscribed. The cerebrovascular insufficience is a difficult diagnostic and therapeutic area, but it is accissible. The psychopathological symptoms to be caused by this disturbance are reversible in many cases. The problems of a comprehensive diagnostic and therapy of sleeping-disturbances at aged people are described.
