Social Security disability benefits (SSDI) may be available to applicants with severe TBI-related long-term physical and mental impairments. Traumatic brain injury was added as a new disability category (listing 11.18) under neurological disorders by Social Security in late 2016. To be eligible for benefits under the listing, your health records must show that you: Are unable to control the movement of at least two of your extremities for at least three months after the injury (either an arm and a leg, two arms, or two legs). Due to this, standing up from a seated position, walking, or using your arms to balance must be extremely difficult. or A “marked” limitation (for at least three months following the injury) in any one of the following areas, in addition to “marked” physical issues: 1. Thinking (trouble understanding, recollecting, or following instructions or other information) 2. Finishing tasks (problems with focus, perseverance, or speed) 3. Regulating emotions and behavior (difficulties with responding to demands, adjusting to changes, or being aware of common dangers) and interacting with others are all examples of poor emotion regulation and behavior control (problems with socially appropriate behavior)
