Alzforum—Loss of synapses in the brain is associated with progression of Alzheimer’s disease (AD). However, a new study shows that in mice, a mutation associated with increased risk of AD results in an excess of synapses. In conjunction with recent work from a few other groups, this suggests that removal of synapses may actually play a protective role against AD, at least early in the disease process.
Shown here is the study’s first author, Melanie Das (left), and Lennart Mucke (right).
