Some posit that gradually progressive vascular dementia, as with small vessel disease, is simply vascular disease plus AD. Because AD presents a characteristic pattern on fluorodeoxyglucose positron emission tomography, we sought to determine whether the fluorodeoxyglucose pattern o...

Methods: We investigated whether executive function in conjunction with prefrontal cortex atrophy discriminates bvFTD and Alzheimer’s disease (AD) patients efficiently at presentation. Results: AD and bvFTD patients were distinguishable by 89.5% on their performance of 3 execu...

Comparing Cerebral White Matter Lesion Burdens between Parkinson’s Disease with and without Dementia

Cerebral white matter lesions (CWMLs) have been suggested to be associated with an increased risk of dementia, disability, and death. CWMLs are more common in individuals with Alzheimer's disease (AD) than in normal elderly individuals of comparable age. Only a few studies have been done to determine whether CWMLs may influence cognitive decline in Parkinson's disease (PD). Fully developed PD w...
