Why We Walk: On behalf of the nearly 7 million American's living with Alzheimer's disease, thank you for rallying around a cause that affects 1 in 3 people in the communities where you work and live. As a Walk to End Alzheimer's® Team, Biogen will be forming teams and raising funds for Walks across the country. The funds raised will help fight Alzheimer's disease through vital research, advocacy efforts and essential support programs and services in your communities. Your team donations will play an important role in improving the lives of people living with Alzheimer's, their families and caregivers.
