Alzheimer’s disease protein structure may vary among patients

Two people with different symptoms had amyloid-beta fibers with different shapes

Alzheimer’s disease proteins may contort differently in every patient.

In the brains of people with Alzheimer’s disease, a protein called amyloid-beta, or A-beta, forms fibers that congregate into plaques. A study now suggests that each person may have a distinct version of the fibers, which could affect how the disease develops.
