[Pharmacological treatment in severe dementia]

Abstract

Medical treatment of severe dementia is now available. Decrease of psychobehavioral disturbances, autonomy loss or care-giver burden appear as the main objective rather than reduction of cognitive deficits. Acetylcholinesterase inhibitors (AChE-I) should be maintained in patients with severe dementia when initiated in mild or moderate dementia. Memantine is the specific treatment for patients with severe dementia, even if they received AChE-I. To treat the psychobehavioral disturbancies, serotoninergic agents and thymoregulators are the first line drugs. Medical treatment should only be co-prescribed with a global care of all co-morbidities, autonomy loss and patient's and care-giver's burden, and associated with psychological and organisational support.
