New drugs for Alzheimer's disease and other dementias.

Background Alzheimer's disease management involves symptomatic drug treatments passed by the National Institute for Clinical Excellence. Disease modification is now the goal. Aims To review current and developmental drugs for Alzheimer's disease, their usage, and the clinical context of known facts and proposed specific models. Method A brief evidence- based review was made, using literature where available, or evidence from consensus groups where it was absent. Results There is good evidence to support the use of cholinesterase inhibitors, and perhaps vitamin E. Oestrogen and anti -inflammatory agents show possibility, but there is not enough evidence to support routine use. Conclusions Symptomatic treatments exist for Alzheimer's disease. Observational studies and increasing knowledge of brain biology are leading towards further treatment options. Old age psychiatrists have valuable treatments they now have to learn to use. Declaration of interest R.B. has worked on clinical trials in dementia for all the major pharmaceutical companies.
