[Subacute hypoglycemic encephalopathy: a case report].
A 63-year-old woman with long lasting diabetes, irregularly nourished and treated with oral antidiabetic drugs, developed hyperkinetic movements in the upper and lower extremities and facial muscles, as well as some disturbances of consciousness. The EEG showed generalized slowing of bioelectrical activity, serum glucose level was 69 mg%. Nevertheless after the antidiabetic drugs were withdrawn and the meals regulated, a normalization of the clinical picture and the EEG was observed. Therefore it seems that the patient was very sensitive to even minor hypoglycemia and the diagnosis of subacute hypoglycemic encephalopathy was made.
