Researchers at the University of California have found that brain scans can foretell if a person will suffer from Alzheimer's. They have proven that sticky amyloid plaques and tau protein tangles which are characteristic of the disease can be spotted and the moment they can trigger Alzheimer's.
Scientists for long now have been trying to find a way to diagnose Alzheimer's disease early and have finally come up with a way to do it. Researchers at the University of California have found that brain scans can foretell if a person will suffer from Alzheimer’s. They have proven that sticky amyloid plaques and tau protein tangles which are characteristic of the disease can be spotted and the moment they can trigger Alzheimer’s. The scientists were also successful in tracking stages of Alzheimer’s in adults who showed no symptoms. The findings suggest that people at risk like those who carry the APOE variant gene should be regularly screened and can also reassure people who have memory problems that they do not suffer from Alzheimer’s.
The study is a breakthrough especially because currently the only way to diagnose Alzheimer’s is to look at brain scans once the patient in dead and for patients who are alive doctors only monitor cognitive and memory skills. This study will enable doctors to use as a diagnostic and staging tool.
The new technology was tested on 53 adults, five of whom were young adults, 33 who were pensioners without any neurodegeneration and 15 who had suspected Alzheimer’s disease. The scientists were able to prove definitively which were clear, at risk and those who had the condition. The findings also shed new light on how tau protein and amyloid plaques build up as the brain ages. For many years, the accumulation of amyloid plaques was considered the main culprit in Alzheimer’s. But now the scientists believe that both tau and amyloid work together to cause the disease.The research was published in the journal Neuron.
