✦ Synopsis
Objective. Our hypothesis was that patients with vascular dementia and a dominating frontal lobe syndrome have a symptomatology that re¯ects a more widespread lesion compared with patients with frontotemporal dementia.
Design. Patients with vascular dementia and a dominating frontal lobe syndrome (VAD-F; N 11) were compared with regard to clinical symptoms and imaging features on CT scans of the brain with patients with frontotemporal dementia (FTD; N 21).
Setting. A neuropsychiatric diagnostic ward.
Patients. Thirty-two inpatients, aged 48±78 years, with frontotemporal dementia or vascular dementia.
Measures. Relatives were questioned about the initial symptoms. At the clinical investigation, mental and neurological symptoms and signs were recorded using the STEP method (stepwise comparative status analysis). CT scan features of the brain were evaluated by a trained neuroradiologist. The GBS-i (Gottfries±BraÊ ne±Steen, intellectual variables) scale was used to measure the degree of dementia.
Results. At the onset of dementia, loss of memory (p0X001), sudden onset ( p 0X001), confusion ( p 0X05) and unspeci®ed neurological signs ( p 0X05) had been signi®cantly more frequent in the VAD-F group. At the time of the clinical investigation, lack of social awareness and presence of primitive re¯exes were more frequent in the FTD group ( p 0X01 and p 0X05, respectively) and visuospatial de®cits more frequent in the VAD-F group ( p 0X05). CT of the brain showed that, apart from brain infarcts (present only in the VAD-F group), paraventricular leukoaraiosis was signi®cantly more pronounced in the VAD-F group ( p 0X05). The groups did not dier with respect to age, age at onset or level of dementia.
Conclusion. The ®ndings support our hypothesis.
