title: [Phototherapy of behavioral disorders as a sequela of disordered circadian rhythm in dementia in the elderly--difficulties in practical clinical applications].
abstract: The behavioral disturbances of 16 nursing home patients with a history of sundowning behaviour and dementia were treated with light therapy instead of psychopharmacological medication. After the withdrawal of the before established medication a very individual, heterogenous deterioration of the symptoms was noted. A significant improvement of the behaviour was not found by light therapy in any patient. The problems in practical handling and possible consequences of further investigation are discussed.
