Beyond Plaques and Tangles 1

In this first of two excerpts from a recent Expert Roundtable on Alzheimer’s Caregiving, Dr. Steven E. Arnold, Harvard Medical School, and Dr. Stephen M. Strittmatter, Yale School of Medicine, give us an overview of what we know about Alzheimer’s disease and other forms of dementia. They explain how fundamental cell biology processes come into play in neurodegeneration and, in particular, the role of synapse malfunction and degeneration in the final common pathway to memory loss and cognition decline.
