Alzheimer's breakthrough hailed as 'turning point'
The discovery of the first chemical to prevent the death of brain tissue in a neurodegenerative disease has been hailed as the "turning point" in the fight against Alzheimer's disease. More work is needed to develop a drug that could be taken by patients. But scientists say a resulting medicine could treat Alzheimer's, Parkinson's, Huntington's and other diseases. In tests on mice, the Medical Research Council showed all brain cell death from prion disease could be prevented.
