Worldwide, over 50 million people live with Alzheimer's Disease or some other form of dementia. This number is growing at an alarming rate, with nearly 10 million new cases each year. Dementia has far-reaching and devastating impact, not only on those diagnosed, but also on their caregivers, families, and society at large.​ After hearing his grandfather had been diagnosed with Alzheimer's, then fifteen-year-old Bill Zhang, like many others, wanted to take action.

​

That summer, he began volunteering at a local senior nursing home playing music, serving food, and interacting with the facility's residents. But after noticing the loneliness, lack of volunteers, and sometimes unsuitable living conditions, Bill decided to do whatever he could to combat these issues.

​

With the help of his two friends Anjay Ambegaonkar and Sachin Naraparaju, the three began by gradually enlisting the help of more student volunteers from nearby schools.

​

What started out as just a small group of students, soon turned into a movement. After several viral articles, business, nonprofits, and volunteers of all ages internationally began reaching out to express their desire to help. In response, DementiAid was created.
