Article and photos from hienalouca.com Alzheimer’s ‘is not one disease’ and can be grouped into six distinct categories, researchers have claimed. Scientists reviewed five existing medical studies which analysed more than 4,000 patients battling the memory-robbing disorder. They discovered Alzheimer’s could be split into six different groups – depending on how badly patients were affected. And they all had genetic differences. The 18-strong research team, from a host of prestigious universities, hope the findings will bring them one step closer towards an Alzheimer’s cure. And they also claim the results could explain why the trials treating all patients with the same drugs often prove unsuccessful.
