[Therapy of Alzheimer dementia. Current status and prospects].

In recent years, considerable progress has been made both in the diagnosis and treatment of dementia. Drugs have been developed which enhance cognitive performance in a large percentage of those afflicted, delay impairment of the ability to cope with the tasks of daily life, and avoid premature admission to a nursing home. In the practical medical care setting, however, these advantages are being utilized to only a limited extent, and this despite the fact that numerous therapeutic options are now available for the treatment of AD. New therapeutic approaches are aimed at inhibiting the pathological cleavage and extracellular and intracellular deposition of amyloid, preventing the toxic effects of amyloid accumulation around the neurons, and re-establishing intracellular transport deranged by the aggregation of neurofibrils. A further approach is the use of combinations of available substances with differing, possibly synergic, effects. Over and beyond this, treatment of AD in the "presymptomatic stage", or in the stage of only mild cognitive disturbance, is currently the subject of clinical trials.
