However, currently no precise knowledge exists regarding the extent to which these factors cause, contribute or only coincide with the cognitive loss. . Potentially reversible causes of the dementia syndrome were found in 19 of these patients 31. It is timely to review this new evidence and place it within the current consensus understanding of what makes up a clearly heterogeneous dementia population. The aging of the population is a universal phenomenon with direct consequences upon the public health system.
Initial power calculations based on estimates of incidence rates of dementia in the target population age 75+ led to a 3000-person study, which was successfully recruited at four clinical sites around the United States from September 2000 to June 2002. Risk factors for dementia in stroke victims include stroke-related and non-stroke related risk factors. The concept of mixed forms of vascular dementia, Alzheimer's dementia and other vascular diseases is discussed as well as the influence of vascular changes with regard to the onset of Alzheimer's disease. These findings suggest that vascular changes in the brain are protective against the development of brain metastases in lung cancer patients. Within populations, Alzheimer's disease was generally more common than vascular dementia. An improved understanding of the cerebrovascular continuum disorders, underlying pathophysiology, and approaches to management of vascular depression is likely to improve the quality of life of patients and their families, and reduce the cost of care for society. Serial Mini-Mental State Examination was administered at 3- to 6-month intervals, and neuroimaging was performed annually.
Of the 27 patients with clinical diagnosis of vascular dementia, 23 showed multiple cerebral infarcts but senile plaques and neurofibrillary tangles were absent or in insignificant numbers. Cerebral blood flow per 100 gm brain per minute was normal in the primary degenerative group but low in the multi-infarct group. These were predominantly multi-infarct or strategic-infarct dementia 66. They await testing and validation and will be revised as more information becomes available. T Mok, Patty Yim, Michael Fu, Wynnie W. The investigation showed that recognition of the six stages required qualitative evaluation of only a few key preparations.
These six patients were excluded from the study. Both men and women benefited from aspirin therapy and their quality of life and independence appeared to be improved, which was not apparent in the control group. Sensitivity and specificity were assessed by comparing the clinical with the neuropathological diagnosis of 89 autopsied patients with dementia from a geriatric and psychiatric hospital. This is a major contribution to the field. Methodological issues of such research and the profound implications of epidemiological studies vascular disease starts early and causes cognitive changes in midlife are emphasized. Treatment of behavioral symptoms in vascular dementia Catherine Cole and Alistair Burns; 18.
Eighty-three brains obtained at autopsy from nondemented and demented individuals were examined for extracellular amyloid deposits and intraneuronal neurofibrillary changes. Primary and secondary stroke prevention, in particular with control of hypertension and hyperlipidemia, can decrease VaD incidence. Cardiovascular pathologies included myocardial infarction, angina pectoris or myocardial ischemia, claudicatio intermittens, and arterial surgery. The aim of secondary prevention is to detect a disease early, when it is asymptomatic, and by treatment prevent it from progressing into a serious outcome. Evidence suggests that these risk factors have a cumulative effect on Alzheimer's disease development but not on vascular cognitive impairment. Besides sharing risk factors with stroke, dementia with multiple small or large brain infarcts is also associated with non-vascular risk factors such as high alcohol consumption, psychological stress in early life, lower formal education, blue collar occupation, and occupational exposures.
One of the main repercussions of the growth in this sector of the population is the increased prevalence of disorders such as dementia and depression which are very frequent among the elderly. Significant improvements were demonstrated for cerebral perfusion values P less than. Side effects and adverse events are tracked by computer at the central data coordinating center and unblinded data are reviewed by an independent safety monitoring board. The cognitive impact of risk appears to be more pronounced in the absence of adequate pharmacological treatment. This much-needed book deserves a wide readership. The epidemic of late life dementia, prominence of use of alternative medications and supplements, and initiation of efforts to determine how to prevent dementia have led to efforts to conduct studies aimed at prevention of dementia. We propose that 1 specific subtypes of vascular dementia should be the target in any single trial using a treatment with a proper rationale; and 2 subcortical vascular dementia, caused by small vessel disease leading to lacunar infarcts and subcortical white matter changes, represents a clinically and radiologically well-defined entity to be considered for future trials designed specifically for testing adequate drugs.
During follow-up, there was a significant cognitive decline and a significant increase of depressive symptoms. This article discusses new principles for the classification of vascular cognitive impairments and reviews the potentials for their therapeutic correction. The proportion of subjects with dementia varied from 3. A significant amount of our patients showed laboratory or imaging changes suggestive of potentially reversible causes of the dementia syndrome upon admission. Although therapy of these potential causes is not always accompanied by a full recovery, the identification and therapy of treatable causes of cognitive deficits are possible even for general practitioners, who often are the primary contact persons of affected individuals.
The knowledge about risk factors for these disorders is still scarce. Damage to white matter or its response to a variety of ischemic conditions may be similar. Cognitive functioning in vascular dementia before and after diagnosis Erika J. Test combinations did not lead to substantial gains in sensitivity or specificity. Cerebrovascular disease is a major factor related to cognitive impairment.
Table of Contents List of Contributors p. Between these two extremes is cognitive loss from multiple lesions, none of which alone would be expected to cause intellectual impairment multiinfarct dementia. Control of vascular risk factors Deborah Gustafson and Ingmar Skoog; Index. Timo Erkinjuntti is Professor of Neurology at the Department of Neurology, University of Helsinki, Finland. Na comparação entre grupos, encontram-se diferenças estatisticamente significativas quanto aos aspectos atencionais. The variable relation between clinical presentation and neuroimaging localization has important consequences for understanding the pathophysiology of cognitive impairment arising from vascular causes. To do this, the current review explores the relationship between Alzheimer's disease, for which this group of compounds originally received licensing approval, and vascular pathology within the brain, highlighting the significant overlap in risk factors and the frequent coexistence of the two conditions in the patients that are studied.
