A 25-year-old man with rapidly progressive amyotrophic lateral sclerosis (ALS) developed focal seizures, including seizures that spread to both sides of the body. Testing found a disease-causing FUS gene variant, and levetiracetam partly controlled the seizures while his motor function continued to worsen. The report identifies focal epilepsy as a possible feature of FUS-associated ALS.
Why this matters
This may be relevant to clinicians evaluating young people with ALS and seizures, because the authors suggest considering FUS genetic testing in that situation. It is based on one patient and does not show that FUS testing or levetiracetam improves ALS or changes treatment outcomes.
Limitations and context
This is a single-patient case report, not a clinical trial or population study. It cannot establish how often seizures occur in FUS-associated ALS, whether the association applies broadly, or whether the finding changes treatment. The reported seizure control was partial, and the patient's motor function continued to deteriorate.
