title: [Kleine-Levin syndrome].
abstract: A case of a 15 years old boy with a Kleine-Levin syndrome is presented. Neurological examination and X-ray studies, including pneumoencephalography, were normal. Laboratory findings were also normal except for a flattened response to glucose load. The EEG was mildly abnormal, showing bifrontal discharges at 3 c/s, a finding already presented in other cases of Kleine-Levin syndrome. The differential diagnoses among the group of periodic hypersomnias is discussed.
