Late onset absence seizures in multiple sclerosis: a case report

Area of Science:

• Neurology
• Neuroimmunology
• Epileptology

Background:

• Late-onset seizures can be a presenting symptom of neurological disorders.
• Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system.
• Epilepsy is a recognized, though uncommon, manifestation of MS.

Observation:

• A 38-year-old woman presented with new-onset generalized tonic-clonic attacks and absence seizures.
• Electroencephalography (EEG) demonstrated generalized spike-wave discharges correlating with impaired consciousness.
• Magnetic resonance (MR) imaging identified multiple demyelinating lesions, notably in the mesial frontal region.

Findings:

• The patient was diagnosed with multiple sclerosis.
• The mesial frontal demyelinating lesion was hypothesized as the cause of absence seizures.
• The study discusses the pathophysiology and differential diagnosis of seizures in MS.

Implications:

• This case highlights the importance of considering MS in adults with new-onset seizures, particularly those with specific EEG and MRI findings.
• Understanding the link between demyelination and epilepsy in MS is crucial for accurate diagnosis and management.
• Further research into the mechanisms underlying MS-related epilepsy may lead to improved treatment strategies.
