Summary
Epilepsia partialis continua (EPC) can occur with diabetic ketoacidosis, a rare presentation. This case highlights the link between ketotic hyperglycemia and continuous partial seizures, suggesting a potential impact on seizure thresholds.
Area of Science:
- Neurology
- Endocrinology
- Metabolic Disorders
Background:
- Epilepsia partialis continua (EPC) is a rare focal epilepsy characterized by continuous focal motor seizures.
- While EPC is known to occur with nonketotic hyperglycemia, its association with diabetic ketoacidosis (DKA) has not been previously documented.
Observation:
- The authors present a case of a patient experiencing EPC in the context of ketotic hyperglycemia, a form of DKA.
- Brain magnetic resonance imaging (MRI) revealed abnormalities in the left precentral gyrus and right cerebellar hemisphere.
Findings:
- This case establishes a novel association between ketotic hyperglycemia and the occurrence of Epilepsia partialis continua.
- The findings suggest that severe hyperglycemia, even in the presence of ketoacidosis, can precipitate or exacerbate epileptic activity.
Implications:
- Hyperglycemia, through mechanisms potentially involving altered gamma-aminobutyric acid (GABA) metabolism, may lower the seizure threshold.
- This case expands the understanding of metabolic encephalopathies and their potential to trigger specific seizure types like EPC.
- Clinicians should consider hyperglycemia, including DKA, as a potential precipitant for EPC in patients with diabetes.
