What Is Vascular Dementia Symptoms Causes Stages Life Expectancy It has been estimated that 20% of all dementia cases have a predominant cerebrovascular pathology, while perhaps another 20% of vascular diseases contribute to a mixed dementia picture. therefore, the vascular contribution to dementia affects 20 million people currently and will increase markedly in the next few decades, particularly in lower and middle income countries. Dementia is characterized by a progressive and unrelenting deterioration of mental capacity that inevitably compromises independent living. advancing age is the main risk factor, and due to the aging of the world population and lack of effective treatments, the number of affected individuals, estimated at 50 million worldwide in 2018, is anticipated to triple by 2050 at a cost approaching $4.
What Are The 7 Stages Of Vascular Dementia Key types of vascular lesions found in the brain as a result of small vessel disease (svd) leading to cognitive impairment (vascular dementia) and stroke include microbleeds, microinfarcts; where fatty deposits accumulate to restrict luminal diameter, and inflammatory white matter pathology such as lipohyalinosis, where hyaline deposits within connective tissue in addition to astrocytic. The lifetime risk of cerebrovascular disease and vascular dementia has age is the most important risk factor identified in the aging brain . microglial dysfunction associated with aging. Vascular risk factors, cognitive decline, and dementia. vascular risk factors, such as hypertension and diabetes, can accelerate the progression of alzheimer’s disease and vascular dementia. Dementia is a neurological disorder that can result from various direct or indirect factors, with age being the primary risk factor for most types of dementia [3]. the main forms of ard include alzheimer's disease (ad), vascular dementia (vad), and frontotemporal dementia (ftd).
