About Epilepsy and Other Seizure Disorders
Epilepsy is a neurological disorder that affects the central nervous system and causes recurring seizures due to abnormal electrical activity in the brain. A seizure disorder is a broad term commonly used to describe conditions involving repeated seizures, including epilepsy.
Not all seizures are caused by epilepsy. Some seizures occur because of other medical conditions or temporary triggers and may not result in an epilepsy diagnosis.
Epileptic vs. Non-Epileptic Seizures
Epileptic Seizures
Epileptic seizures typically occur without a clear external cause and tend to recur over time. Individuals who experience repeated unexplained seizures are often diagnosed with epilepsy.
Non-Epileptic Seizures
Non-epileptic seizures occur due to a direct and identifiable cause, such as fever, injury, illness, or another medical condition affecting brain activity. Individuals experiencing seizures with a known cause are not always diagnosed with epilepsy.
Types of Seizures
Seizures can vary greatly in severity, duration, symptoms, and the areas of the brain affected.
Partial (Focal) Seizures
Partial seizures, also called focal seizures, originate in a single area of the brain.
Generalized Seizures
Generalized seizures involve abnormal electrical activity affecting both sides of the brain.
Absence Seizures (Petit Mal Seizures)
Absence seizures involve brief staring episodes, reduced awareness, and little or no movement. These seizures may resemble daydreaming.
Tonic Seizures
Tonic seizures cause sudden stiffening of the muscles.
Atonic Seizures (Drop Seizures)
Atonic seizures involve a sudden loss of muscle control, often causing the individual to collapse or fall unexpectedly.
Clonic Seizures
Clonic seizures cause repeated jerking or twitching movements, commonly affecting the arms, legs, neck, or face.
Myoclonic Seizures
Myoclonic seizures involve quick, sudden jerking movements of the arms or legs.
Tonic-Clonic Seizures (Grand Mal Seizures)
Tonic-clonic seizures are often considered the most severe seizure type. Symptoms may include:
Loss of consciousness
Muscle stiffening and jerking
Loss of bladder control
Tongue biting
Convulsions lasting longer than many other seizure types
Qualifying for Social Security Disability with Epilepsy
The Social Security Administration (SSA) evaluates epilepsy and seizure disorders under the neurological listings in the Blue Book.
Epilepsy claims are generally evaluated under:
Listing 11.02 – Convulsive Epilepsy
Listing 11.03 – Non-Convulsive Epilepsy
The SSA requires detailed medical documentation describing the frequency, severity, duration, and effects of seizures despite prescribed treatment.
Listing 11.02 – Convulsive Epilepsy
Listing 11.02 generally applies to grand mal or psychomotor seizures.
To qualify, the applicant must have:
A detailed description of a typical seizure pattern
Seizures occurring at least twice per month
Symptoms continuing despite at least three months of prescribed treatment
The applicant must also satisfy one of the following requirements.
Requirement A – Daytime Seizures
The applicant experiences daytime seizures involving:
Loss of consciousness
Convulsive seizures
Requirement B – Nocturnal Seizures
The applicant experiences nighttime seizures that leave residual effects significantly interfering with daytime functioning and activities.
Listing 11.03 – Non-Convulsive Epilepsy
Listing 11.03 generally applies to petit mal, focal, or psychomotor seizures.
To qualify, the applicant must have:
A detailed description of a typical seizure pattern
Seizures occurring more frequently than once per week
Symptoms continuing despite at least three months of prescribed treatment
Qualifying with Other Seizure Disorders
Other seizure disorders are generally evaluated under the same listings used for epilepsy.
The SSA considers:
The type of seizure
Frequency of seizures
Response to treatment
Impact on daily functioning
Safety concerns
Residual symptoms after seizures
The SSA also reviews whether seizures continue to occur despite following prescribed medical treatment.
Medical Evidence for an Epilepsy or Seizure Disorder Claim
Strong medical evidence is critical in seizure-related disability claims. Helpful documentation may include:
Neurology treatment records
EEG testing results
MRI or CT scans
Hospitalization records
Witness statements describing seizure activity
Medication history and treatment compliance
Physician observations regarding seizure frequency and severity
The SSA evaluates how seizures affect an individual’s ability to work, maintain safety, concentrate, drive, perform daily activities, and function consistently in a work environment.
