치매로 의심되어 내원한 74세 여자환자

초록

The knowledge about nutritional, toxic, and metabolic causes of dementia is particularly important, because they may be reversible. Central pontine myelinolysis(CPM) is one of these causes. CPM is a well known but rare metabolic disease of unknown etiology linked to overly aggressive correction of hyponatremia. We report a 74-year-old woman who developed disorientation, memory disturbance, and behavioral problem following intensive care unit management for pneumonia. Mini-mental status examination-Korean version(MMSE-K) study revealed severe cognitive dysfunction. Brain magnetic resonance imaging showed changes consistent with CPM and extrapontine myelinolysis. After supportive care, patient's clinical status was significantly improved. We suggest that a metabolic problem such as CPM should be considered in the diagnosis of acute or subacute cognitive deterioration in elderly patients.
