  1. Dynamic light scattering spectroscopy predicts cerebral amyloid in humans (100% sensitivity, 83% specificity).

    “DLS testing correctly identified all 10/16 (100%) of the patients that were positive for amyloid, and 5/6 (83%) patients that were negative for amyloid.”

Sleep's link to brain damage varies with other vessel injuries

In an observational study of 735 people, other brain vessel injuries strengthened links between shorter sleep and brain lesions in some diagnostic groups.In an observational study of 735 people, other brain vessel injuries strengthened links between shorter sleep and brain lesions in some diagnostic groups.

Severely enlarged brain vessel spaces predicted bleeding lesions

Over a median 5.1 years, bleeding-related lesions appeared in 33.7% of participants with severe enlargement versus 13.6% without severe enlargement.Over a median 5.1 years, bleeding-related lesions appeared in 33.7% of participants with severe enlargement versus 13.6% without severe enlargement.
