Alzheimer's disease causes incresing neurodegeneration of the brain, leading to accelerated memory loss. The incorrect folding of proteins leads to the formation of amyloid plaques. Current research aims to determine if such plaques are the result of, or the cause of, Alzheimer's disease.
Treatment
There is currently no cure for Alzheimer's disease. Currently available medications offer relatively small symptomatic benefit for some patients but do not slow disease progression. The American Association for Geriatric Psychiatry published a consensus statement on Alzheimer's treatment in 2006.[1]
Atypical antipsychotics
A systematic review found that the atypical antipsychotics risperidone and olanzapine showed the most benefit of all drugs; however they may increased the risk of stroke.[2]
Acetylcholinesterase inhibitors
Randomized controlled trials showed either small or absent benefit from acetylcholinesterase inhibitors[3] such as donepezil.[4][5]
N-methyl d-aspartate (NMDA) antagonists
The N-methyl-d-aspartate receptor antagonist memantine has shown effectiveness.[6]
