| IRS990/Desc | 0 | Grants and Awards The Foundation receives donations from the American Academy of Neurology (AAN), AAN members, industry, and the public to help fund 20 clinical training research fellowships. These fellowships are designed to support some of the brightest young neuroscientists in the country with two- or three-year awards. The Foundation also collaborates with other organizations, including the AAN, and individuals to support awards that recognize the accomplishments of veteran researchers, medical students, and minority students interested in careers in neurology. The Foundation provides scholarships to minorities and to students to attend the Annual Meeting based on their financial need, so that they may experience this great event and learn from leading neurology professionals. |
