Four distinct variants of Alzheimer’s identified in brain imaging study
A new international study has found four distinct patterns of toxic protein spread in the brains of patients with Alzheimer’s disease. The findings indicate these patterns correspond with particular symptoms, and the researchers hypothesize these four variants could respond to different treatments.
The research focused the accumulation and spread of a toxic protein in the brain called tau. Alongside amyloid beta, another protein known to be implicated in neurodegeneration, the spread of tau has been associated with cognitive decline seen in Alzheimer’s.
