Neuronal ceroid lipofuscinosis (NCL) is a rare disease with onset typically during childhood; however, that developing during adulthood can lead to early-onset dementia. We report a 54-year-old man whose onset coincided with speech impairment, amnesia and dyscalculia. On brain MRI, marked diffuse leukoencephalopathy with periventricular predominance was observed. On a skin biopsy, characteristic fingerprint images were noted, and the patient was diagnosed with NCL. The differential diagnosis of cognitive impairment with leukoencephalopathy is wide ranging; however, when marked symmetrical periventricular-predominant leukoencephalopathy is prevalent and no peripheral neuropathy or gait disorders are evident, a diagnosis of NCL should be suspected and a skin biopsy should be performed.
