A 49-year-old man with neuropsychiatric symptoms followed by progressive cognitive decline.

摘要

A 44-year-old man with a 4-year history of progressive neuropsychiatric symptoms, including irritability, apathy and hyposex-uality, was admitted to another hospital because of increasing impairment of executive functions, delusions, paranoid ideation and mild cognitive decline. Physical and laboratory examinations were normal. An electroencephalogram (EEG) study showed focal theta activity over the right frontal areas, whereas a brain magnetic resonance image (MRI) revealed mild cortical atrophy of the right hemisphere.
