Can You Get SSDI for Conversion Disorder?

TL;DR: Yes. Conversion disorder, now called functional neurological symptom disorder (FND), causes real neurological symptoms like paralysis, seizures, blindness, or inability to speak that are not explained by a neurological disease. The SSA evaluates FND under Listing 12.07 (somatic symptom and related disorders) or under the neurological listings if the symptoms match specific criteria. The key challenge is proving the symptoms are genuine and persistent, since the condition carries a stigma of being "psychological" rather than "real."

Conversion disorder produces symptoms that look exactly like neurological disease. Non-epileptic seizures, limb weakness, tremor, difficulty walking, speech problems, and vision loss are all common presentations. These symptoms are involuntary and the person is not faking them. The brain is generating real neurological dysfunction even though there is no structural damage visible on MRI or other tests.

SSA Listings for Conversion Disorder

SSA ListingConditionKey Requirements
12.07Somatic symptom and related disordersNeurological symptoms not explained by medical condition, plus marked limitation in 2 Paragraph B areas
11.02Epilepsy (convulsive)If non-epileptic seizures meet frequency criteria
11.14Peripheral neuropathyIf functional weakness meets motor dysfunction criteria

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.

Medical Evidence the SSA Needs

  • Neurologist diagnosis with positive clinical signs of FND (Hoover sign, tremor entrainment, etc.)
  • EEG during seizure-like episodes confirming non-epileptic events
  • Normal MRI and other neurological tests ruling out structural disease
  • Psychiatric or psychological evaluation
  • Video of functional seizures or movement abnormalities if available
  • Documentation of functional limitations from the neurological symptoms
  • Treatment records: physical therapy, CBT, medication trials

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.

Common Denial Reasons

  • Viewed as "not real." Despite being a recognized medical condition, some SSA reviewers still dismiss FND. Having a neurologist confirm the diagnosis with positive clinical signs helps.
  • Normal neurological tests cited. Normal MRI and EEG are expected in FND. Your records should explain that these are consistent with the diagnosis, not evidence against it.
  • Symptoms fluctuate. FND symptoms can vary day to day. Document the overall pattern and average level of limitation.

A denial does not mean your case is over. About 2 out of 3 initial SSDI applications are denied, and many of those denials are overturned on appeal. Read your denial letter carefully. It tells you exactly why SSA denied your claim. The most common reasons are insufficient medical evidence and SSA determining you can still perform some type of work. You have 60 days from the date on your denial letter to file an appeal. Missing this deadline means starting over from scratch, so mark it on your calendar immediately.

Compassionate Allowance

Conversion disorder does not qualify for Compassionate Allowance.

Function Report Tips

  • Describe your neurological symptoms in detail: what happens during a seizure, how weakness affects you
  • Explain that these are involuntary symptoms you cannot control
  • Detail how episodes affect your safety and ability to be in a workplace
  • Describe the unpredictability of symptoms and how it prevents reliable attendance
  • Note any injuries from falls during episodes

FND claims need careful framing. ClaimPath generates SSA-compliant disability documents for $79, saving you the 25% attorney contingency.

Report any changes within 10 days of the change occurring. This includes starting or stopping work, changes in your medical condition, moving to a new address, or receiving other benefits. You can report changes online through your my Social Security account, by calling SSA at 1-800-772-1213, or by visiting your local SSA office. Keep a record of what you reported and when. Failing to report changes can result in overpayments. SSA will recover overpayments by withholding future benefits, and in some cases, overpayments can reach thousands of dollars.

What to Do Next

  • Check the date on your denial letter and mark your 60-day appeal deadline on a calendar. Missing this window means restarting the entire process.
  • Request a complete copy of your SSA file (called the 'exhibit file') so you can see exactly what evidence the reviewer had, and identify any gaps you need to fill.
  • Get an updated RFC form from your treating doctor that addresses the specific reasons listed in your denial. If SSA said you can do sedentary work, your doctor needs to explain why you cannot.
  • Contact a disability attorney for a free case evaluation. Most work on contingency, so you pay nothing unless you win.
