What you have to prove
Qualify via: (1) generalized tonic-clonic seizures at least once a month for 3 consecutive months despite treatment, OR (2) dyscognitive seizures at least once a week for 3 consecutive months, OR (3) generalized tonic-clonic seizures at least once every 2 months for 4 months WITH a marked limitation in physical functioning, understanding/applying information, interacting with others, concentrating/persisting, or adapting.
Medical evidence SSA expects
Neurologist records, EEG results, medication list with blood levels confirming compliance, seizure diary, MRI/CT of brain, and witness statements from family.
Common misconceptions
Missing medication doses will often disqualify you — SSA wants documented adherence via blood levels. Also, seizures must be witnessed or documented; self-reported seizures without corroboration are weighted less.
