Imaging Suggests Wide Window for Alzheimer's Tx

February 28, 2013

The biological path to Alzheimer's disease might continue for more than a decade, suggesting a broad window of opportunity for intervention, according to a study of amyloid plaque accumulation.

Longitudinal measurement by PET imaging showed that plaque buildup reached a plateau at 2.7 times baseline values, a process that required about 15 years.
