What you have to prove
Show one of: (A) disorganization of motor function in two extremities with extreme limitation persisting at least 3 months post-injury; OR (B) marked limitation in physical functioning AND marked limitation in one area of mental functioning, both persisting at least 3 months post-injury.
Medical evidence SSA expects
Initial imaging (CT/MRI) and post-injury follow-up imaging, neuropsychological testing, rehabilitation records, and functional assessments.
Common misconceptions
TBI recovery continues for 6-12+ months post-injury. SSA will usually not fully evaluate until at least 3 months and often waits longer to allow for recovery.
