Description
Ashouri tests whether a very strong MRI scanner finds more tiny brain bleeds in people with memory problems. The bleeds, called cerebral microbleeds, mark small vessels damaged by amyloid, a process tied to Alzheimer's disease. Standard scans miss some of them. A 7-tesla scanner, far stronger than clinic norms, sharpens the magnetic clues these bleeds leave.
Twelve older adults were scanned: four with mild impairment, two with Alzheimer's, and six healthy. Nearly all bleeds in the patient group sat in the brain's outer lobes, and their count tracked with amyloid levels on PET scans. Healthy participants showed only three bleeds. The author says the stronger scans could matter for trials of amyloid drugs, where bleed counts guide safety calls.
