This is a single center, 22-month observational study of nusinersen treatment in adult patients with SMA. There will be a total of five visits. All subjects will be evaluated at a screening visit no more than four weeks before starting their standard of care nusinersen treatment to determine their eligibility for participation. Eligible patients will complete their standard induction intrathecal nusinersen treatment on day 1, 15, 29 and 60 followed by maintenance doses every four months. Subjects will be reevaluated after completing the loading doses at 2 months followed by every four-month evaluations for the total duration of the treatment of 22 months.~Currently, there is no data published on patients receiving this treatment over the age of 18.

This study hopes to collect data, in order to make this treatment option easier for patients with SMA to access and in general learn how well nusinersen is working in adult patients with SMA overtime.
