Frontotemporal dementia versus vascular dementia: differential features on mental status examination.
After Alzheimer's disease, vascular dementia (VaD) and frontotemporal dementia (FTD) are among the most common dementing illnesses. FTD may have a neuropsychological profile similar to that of VaD, and patients with these dementias may be difficult to distinguish on clinical examination. The purpose of this study was to elucidate distinct cognitive profiles of a large group of FTD and VaD patients on a brief, clinical mental status examination. ⋯ These results suggest that cognitive differences between FTD and VaD groups reflect greater frontal pathology in contrast to relative sparing of posterior cortex and subcortical white matter in FTD. These cognitive differences as measured by a mental status examination may help distinguish between these two dementia syndromes.
