Tau-protein better predicts brain atrophy in Alzheimer's patients than amyloid plaques

Brain imaging of pathological tau-protein "tangles" reliably predicts the location of future brain atrophy in Alzheimer's patients a year or more in advance, according to a new study by scientists at the UC San Francisco Memory and Aging Center. In contrast, the location of amyloid "plaques," which have been the focus of Alzheimer's research and drug development for decades, was found to be of little utility in predicting how damage would unfold as the disease progressed.

Obj-SCD predicts future amyloid accumulation and neurodegeneration

Writing in the December 30, 2019 online issue of Neurology, researchers at University of California San Diego School of Medicine and Veterans Affairs San Diego Healthcare System report that accumulating amyloid -- an abnormal protein linked to neurodegenerative conditions such as Alzheimer's disease -- occurred faster among persons deemed to have "objectively-defined subtle cognitive difficulties" (Obj-SCD) than among persons considered to be "cognitively normal."

MIT engineers generate first laser ultrasound images in humans

For most people, getting an ultrasound is a relatively easy procedure: As a technician gently presses a probe against a patient's skin, sound waves generated by the probe travel through the skin, bouncing off muscle, fat, and other soft tissues before reflecting back to the probe, which detects and translates the waves into an image of what lies beneath.

McGill study finds new role of apolipoprotein E4 gene in Alzheimer’s disease

For years, physicians have been aware that patients carrying the apolipoprotein E4 (APOEε4) gene are at a greater risk of developing Alzheimer's disease. New research from McGill University has now found the gene plays an even greater role in dementia.
