What you have to prove
ALS established by clinical and laboratory findings in accordance with generally accepted medical standards.
Medical evidence SSA expects
Neurologist's diagnosis (ideally from a specialist or ALS center), EMG/NCS, and documentation of upper and lower motor neuron signs.
Common misconceptions
ALS is a Compassionate Allowance — approvals typically within weeks of application. The 5-month SSDI waiting period was eliminated for ALS in 2021.
Didn't meet the listing? You can still qualify via a Medical-Vocational
Allowance — SSA's determination that your residual functional capacity, combined with
your age, education, and work history, leaves no jobs you can do. See our
appeals guide for what to do after an initial denial.
