Seizures and non-ketotic hyperglycemia
- In patients older than 50 years, a first seizure can reveal non-ketotic hyperglycemia, regardless of any previous history of diabetes mellitus.
- Partial motor seizures are observed in most cases, sometimes with epilepsia partialis continua.
- Plasma glucose levels are usually above 20 mmol/L, and serum osmolarity is normal or slightly elevated.
- The absence of ketoacidosis may promote the occurrence of seizures.
- EEG and neuroimaging between seizures are usually normal.
- Treatment involves correction of the hyperglycemia with insulin treatment and rehydration.
