Abstract

Hypereosinophilic syndrome is a rare disease, characterized by hypereosinophilia of the blood and by the presence of varying internal symptoms and neurological signs. We report a 70-year-old woman who was admitted with rapidly progressive cognitive dysfunction, which had begun 10 months earlier. On admission, she had hypereosinophilia with elevated IgE. Following steroid therapy, there was rapid improvement of dementia. Considering the possibility of irreversibility at delayed intervention, the early diagnosis and treatment of dementia due to hypereosinophilic syndrome cannot be overemphasized.
