      <Desc>Membership: Even in the face of a second year of the calamitous pandemic and widespread economic uncertainty, the AAN continued to prove its value to neurology by logging yet another record for membership recruitment and retention. Neurologists and neuroscience professionals from around the world now make up more than 38,000 AAN members. This success is due to the AAN's ongoing commitment to grow the available resources for neurologists and members of a neurology care team no matter their practice setting, career stage, or geographic location.</Desc>

        <Desc>Training/Tools/Resources: Our accomplishments in 2021 were vital to the members of the Academy. We successfully lobbied Congress to continue to support key telehealth initiatives that allowed patients to access their neurologists safely and in a timely manner. We also were successful in convincing Congress to avert the "Medicare Cliff" that would have caused a nearly 10-percent reduction to Medicare reimbursement on January 1, 2022. And our advocacy efforts led Congress to increase critical research funding. We continued to push to improve access to neurologic care by expanding the professional pipeline of students into the neurology specialty; engaged advanced practice providers (APPs) as key members of the neurology patient care team and increased their numbers to a new record level of members; and kept members informed of the latest health care changes, particularly about the COVID-19 pandemic.</Desc>

        <Desc>Publications: The publication of scientific, scholarly, and practice-related content is a vital part of the AAN's activities, and essential to the careers of our members. The AAN's publications provide this content and resources to Academy members, and also provide an opportunity to generate revenue that helps keep membership dues low.</Desc>
