How to Apply for SSDI After Traumatic Brain Injury
TL;DR: TBI qualifies under SSA Listing 11.18 (Traumatic brain injury). You need documentation of disorganization of motor function in two extremities, or marked limitation in physical functioning plus a Paragraph B mental limitation, persisting 3+ months after injury. Brain imaging, neuropsychological testing, and rehab records are essential.
Traumatic brain injury claims require documenting the full scope of deficits, which often span physical, cognitive, behavioral, and emotional domains. The SSA evaluates TBI under Listing 11.18, with a 3-month waiting period after injury to allow for initial recovery before determining persistent deficits.
SSA evaluates disability claims using the Blue Book, which lists qualifying conditions and the specific criteria each must meet. If your condition matches a Blue Book listing, approval is more straightforward. Even if your condition does not match a Blue Book listing exactly, you can still qualify through a medical-vocational allowance. This considers your age, education, work experience, and functional limitations together. Consistent treatment records are critical. SSA looks for ongoing documentation showing your condition limits your ability to work, not just a single diagnosis.
SSA Listing 11.18 (Traumatic brain injury)
The SSA evaluates this condition under Listing 11.18 (Traumatic brain injury). To meet or equal the listing, you need documented medical evidence showing severity that meets or exceeds the listing criteria. Even if you do not meet the exact listing, the SSA will evaluate your Residual Functional Capacity to determine what work, if any, you can still perform.

Essential Evidence
- Brain CT or MRI showing injury
- Neuropsychological testing battery
- Neurologist evaluation documenting persistent deficits
- Rehabilitation records (physical, occupational, speech therapy)
- Cognitive rehabilitation records
- Behavioral health records for personality/mood changes
- Pre-injury vs. post-injury functional comparisons
Request your medical records directly from each provider rather than relying on SSA to gather them. SSA requests can take months, and records sometimes get lost in the process. Include records from every provider you have seen for your disabling conditions, even if a visit seemed minor. Gaps in treatment history are one of the most common reasons for denial. Medical records from the past 12 months carry the most weight, but older records help establish the onset date. A treatment history spanning several years shows the condition is persistent, not temporary.
Describing Your Condition on the Application
Neuropsych testing shows severe deficits in processing speed, working memory, and executive function compared to pre-injury baseline. I cannot remember conversations from 30 minutes ago. I lose my temper over minor frustrations, which is new since the injury. I have persistent headaches rated 5-7/10 daily. I cannot read more than a paragraph without losing comprehension. I get lost driving to familiar places. I require supervision for safety because I forget to turn off the stove and leave doors unlocked.

Building a Stronger Claim
- See specialists regularly (not just primary care) for condition-specific documentation
- Document failed treatments to show your condition is resistant to intervention
- Track symptoms daily in a log or diary
- Ask your doctor for a functional capacity assessment or RFC opinion letter
- Report medication side effects as additional limitations
- List all co-occurring conditions on your application
