BACKGROUND AND PURPOSE Recent reports suggest that vascular factors play a crucial role in the development and progression of Alzheimer's disease. We aimed to assess vasomotor reactivity in patients with Alzheimer's disease and vascular dementia due to microangiopathy using transcranial Doppler sonography and near-infrared spectroscopy during a CO(2) exposition task. METHODS The normalized CO...

Cognitive decline after stroke is more common than stroke recurrence. Stroke doubles the risk of dementia and is a major contributor to vascular cognitive impairment and vascular dementia. Neuropathological studies in most cases of dementia in the elderly reveal a large load of vascular ischemic brain lesions mixed with a lesser contribution of neurodegenerative lesions of Alzheimer disease. No...

Objective To test the hypothesis that low density lipoprotein (LDL) cholesterol due to genetic variation in the genes responsible for LDL cholesterol metabolism and biosynthesis(PCSK9 and 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR), respectively) is associated with a high risk of Alzheimer's disease, vascular dementia, any dementia, and Parkinson's disease in the general population.Design ...

Despite advances in elucidating the genetic epidemiology of Alzheimer's disease and frontotemporal dementia, the aetiology for most patients with dementia remains unclear. We examined the genetic epidemiology of dementia in a recent genetically isolated Dutch population founded around 1750. The series of 191 patients ascertained comprised 122 probable Alzheimer's disease patients with late onse...

To explore the pathological substrates of mixed dementia, we performed a detailed analysis of lacunar and microvascular pathology in 156 autopsied, elderly individuals with various degrees of Alzheimer's disease (AD) pathology. Cognitive status was assessed prospectively using the Clinical Dementia Rating (CDR) scale; neuropathological evaluation included Braak neurofibrillary tangle (NFT) and ...

Abstract Background Dementia risk and benefit of lipid lowering in individuals with severe hypercholesterolemia has not been well studied. The aim this study was to evaluate the dementia effect population using nationwide cohort. Methods This performed National Health Insurance Service database Korea. Among who took health check-up were followed-up, 1,584,401 enrolled analyzed. Study categorize...

There is little doubt that dementia is a very common cause of disability and dependency in our society. Since dementia of whatever type is usually more common with increasing age, then as population demographics change, so will the prevalence of dementia. Dementia is a generic term and the objective for clinicians, once dementia is suspected, is to attempt to define the cause. Alzheimer’s disea...

Subcortical arteriosclerotic encephalopathy is a chronic vascular dementia with hydrocephalus characterized clinically by: (i) subacute focal neurological deficit; (ii) acute strokes; (iii) dementia; (iv) motor signs and pseudobulbar palsy; (v) hydrocephalus; (vi) persistent hypertension and systemic vascular disease; and (vii) a lengthy course. The pathogenesis is most probably ischaemic chang...

Demographic changes and improvements in health care are projected to result in dramatic increases in the prevalence of dementia. Alzheimer's disease is widely considered to be the primary cause of dementia - a disease for which there is currently no cure nor effective treatment, and for which it is thought that little can be done to mitigate risk. However, an increasing understanding of the rol...
