Focal epileptic seizures can be the first manifestation of a diabetic disorder. Metabolic disturbances, including hyperglycemia, mild hyperosmolality, hyponatremia, and lack of ketoacidosis contribute to the development of partial focal seizures. A review of the medical literature for partial focal seizures is presented, followed by a case study of a patient who developed clonic seizures of the right foot secondary to hyperglycemia, hyponatremia, and hyperosmolality.
