MINNEAPOLIS (WCCO) — Thousands of people turned downtown Minneapolis purple this morning, walking to end a brain disease.

Some 10,000 people took part in this year’s Walk to End Alzheimer’s at Target Field. Teams raised more than $1 million, the most of the 600 walks held across the country.

WCCO has been documenting the story of Paul Quinn. A retired doctor and navy admiral, he’s in the beginning stages of Alzheimer’s.

All of the money raised goes to Alzheimer care, support and research. You can still donate here.
