Research on the causes of Alzheimer's disease has been extraordinary. Alongside this research there have been many promising drugs developed. These drugs work well in the labs, at a cellular level, and they seem to work in trials on animals. But again and again when these drugs are tested on people the medical trials fail because they do not show the progress promised. Professor Simon Lovestone, from Oxford University explains how he believes this is because the trials are being done on people who already show established signs of dementia, and by then the damage is too far advanced for the drugs to be effective.
