Complex Partial Seizure as a Manifestation of Non-Ketotic Hyperglycemia: The Needle Recovered From Haystack?

We present a case of a 75-year-old gentleman with undiagnosed type 2 diabetes mellitus presenting with acute onset expressive dysphasia and right hemi-paresis with no prior history of seizure. He developed clusters of stereotypical complex partial seizures which were refractory to anti-epileptic agents. He was not known to have diabetes and his brain MRI was normal. His random blood sugar measurement on admission to hospital was 30 mmol/L with HbA1c measurement of 14.8%. His seizures terminated completely when his hyperglycemia was corrected with insulin and rehydration therapy.
