Dementia Matters

About the Host

doctor nathaniel chin

Dr. Nathaniel Chin is host of Dementia Matters. He is a geriatrician, memory clinic doctor, and medical director for the Wisconsin Alzheimer's Disease Research Center. His father's diagnosis with early onset Alzheimer’s disease inspired him to pursue a career as a geriatrician and scientist focused on dementia prevention, especially in regard to Alzheimer's disease.

Dementia Matters is a podcast about Alzheimer’s disease and other causes of dementia. Host Dr. Nathaniel Chin interviews leading scientists and caregiving experts to bring listeners the latest in Alzheimer's disease news, research and caregiver resources.
