People with vascular dementia may also present with general slowing of processing ability, difficulty shifting sets, and impairment in abstract thinking. Apathy early in the disease is more suggestive of vascular dementia. [2] [5] Rare genetic disorders that cause vascular lesions in the brain have other presentation patterns.
CAA is associated with brain hemorrhages, particularly microhemorrhages.The accumulation of amyloid beta peptide deposits in the blood vessel walls results in damage of the blood vessels and hindrance of normal blood flow, making blood vessels more prone to bleeding [10] Since CAA can be caused by the same amyloid protein that is associated with Alzheimer's dementia, brain bleeds [11] are more ...
Atrial fibrillation causes blood clots to form within the heart, which may travel to the arteries within the brain and cause an embolism. The embolism prevents blood flow to the brain, which leads to a stroke. [26] An aneurysm is an abnormal bulging of small sections of arteries, which increases the risk of artery rupture.
Binswanger's disease is a type of subcortical vascular dementia caused by white matter atrophy to the brain. However, white matter atrophy alone is not sufficient for this disease; evidence of subcortical dementia is also necessary.
While dementia is often seen as an untreatable and progressive condition, evidence suggests that leading a healthy lifestyle and addressing vascular risk factors early on may help preserve ...
Senile dementia, fronto-temporal dementia, and vascular dementia; Pick's disease, causes progressive destruction of nerve cells in the brain; Huntington's disease, and other genetic disorders that cause build-up of toxic levels of proteins in neurons; Leukodystrophies, such as Krabbe disease, which destroy the myelin sheath that protects axons
This condition may occur due to various different causes, including degenerative, autoimmune, or infectious processes. The most common form of early onset dementia is Alzheimer's disease, followed by frontotemporal dementia, and vascular dementia, with Alzheimer's disease accounting for between 40 and 50% of cases.
Many causes of dementia are neurodegenerative, and protein misfolding is a cardinal feature of these. [60] Other common causes include vascular dementia, dementia with Lewy bodies, frontotemporal dementia, and mixed dementia (commonly Alzheimer's disease and vascular dementia).
