Scientists reveal cellular changes unique to early Alzheimer’s disease

Most Alzheimer’s disease research on human brain tissue has studied postmortem samples, making it difficult for scientists to discern the earliest events in the brain that might have triggered the buildup of plaques and the death of neurons. Knowing the molecular changes in neurons, glia, and other brain cells around plaques during the early phases of the disease could help scientists design treatments that work best when given early.
