Summary
This study identifies a specific epilepsy syndrome in adults with a history of childhood absence seizures. These patients experience persistent absence seizures upon waking, impacting daily function.
Area of Science:
- Neurology
- Epileptology
- Clinical Neurophysiology
Background:
- Epilepsy is a chronic neurological disorder characterized by recurrent seizures.
- Absence seizures, a type of generalized epilepsy, often begin in childhood.
- Understanding seizure evolution and adult manifestations is crucial for effective management.
Observation:
- Four adult patients (40-60 years) with poorly controlled epilepsy were studied.
- All patients had a history of childhood absence seizures (onset 4-7 years) and adolescent generalized tonic-clonic seizures.
- Adults exhibited persistent typical absence seizures upon awakening, presenting as 'clumsiness'.
Findings:
- Electroencephalogram (EEG) polygraphs revealed generalized polyspike/wave during non-REM sleep.
- EEG also showed generalized spike/wave with loss of consciousness and intermittent slow polyspike/wave with bradypsychia upon waking.
- These EEG findings confirm specific seizure patterns associated with the observed clinical presentation.
Implications:
- This case series highlights a distinct epilepsy phenotype with specific diagnostic EEG characteristics.
- Valproic acid, alone or with ethosuximide, shows potential utility in managing this adult epilepsy syndrome.
- Further research is warranted to validate these findings and optimize treatment strategies.
