Currently, there are no drugs which reverse or cure the brain damage caused by Alzheimer's disease or other forms of dementia. Most of the drugs prescribed and used in dementia management are usually done so in an effort to control or minimise the behavioural symptoms of the disease. But ALL drugs have side effects which often cause a worsening of the behaviours which they are trying to control. Therefore, drug use for behavioural management is hazardous and mostly ineffective, and should only be considered as a last resort approach.
