Abnormal Hair Samples From Patients With Alzheimer Disease

Arch Dermatol. 1998;134(10):1300. doi:

We studied 40 hair samples: 20 from patients with Alzheimer disease (mean [± SEM] age, 77 ± 85 years; 4 women and 1 man) and 20 from patients without dementia (mean age, 83.3 ± 7 years; 4 women and 1 man).
