title: Frontal lobe dementia presenting as personality disorder.
abstract: The early differential diagnosis of frontal lobe dementia is particularly difficult because changes of personality or behaviour overwhelm intellectual and cognitive impairments. We report the case of a patient presenting with paranoid personality disorder who refused to collaborate in neuropsychological testing. Initial functional imaging showed frontal hypometabolism that served as an early marker of frontal lobe dysfunction.
