PET scans and lumbar punctures are solely at the moment out there to round 2% of individuals recognized with Alzheimer’s, he mentioned.
He mentioned figuring out Alzheimer’s illness early and precisely “will turn out to be much more vital as a brand new era of remedies emerges that may decelerate the decline of reminiscence and considering”.
