Dementia of frontal type and simple schizophrenia: Two sides of the same coin?

Dementia of frontal type and simple schizophrenia have many overlapping features; both present with insidious onset of functional, social and occupational decline and have features of affective blunting, poor motivation and lack of insight in common. Neuropsychological assessment and neuroimaging may not always separate these two conditions in their early stages. We present an illustrative case and discuss pitfalls in the diagnosis and suggest areas for future research.
