Vascular Dementia Pathology, Animation

September 8, 2019


vascular dementia refers to a group of
conditions in which impaired blood supply to the brain causes neuronal
dysfunction leading to loss of memory and other cognitive abilities it is the
second most common type of dementia after Alzheimer’s a neurodegenerative
disease vascular dementia may develop following a stroke or a series of
mini-strokes a stroke can be ischemic or hemorrhagic an ischemic stroke happens
when a blood clot blocks an artery interrupting blood flow blood clots may
form locally on top of cholesterol plaques as these rupture or travel to
the brain from the heart in a condition known as atrial fibrillation where the
heart does not pump properly blood stagnates and coagulates hemorrhagic
stroke on the other hand occurs when an artery leaks or ruptures this can result
from high blood pressures overuse of blood thinners anticoagulant drugs or
abnormal formations of blood vessels such as aneurysms as a hemorrhage takes
place brain tissues located beyond the site of bleeding are deprived of blood
supply bleeding also induces contraction of blood vessels narrowing them and thus
further limiting blood flow dementia symptoms may appear suddenly following a
single large stroke or develop in a stepwise fashion as a result of multiple
sometimes unnoticeable small strokes symptoms vary from person to person
depending on the part of the brain that is affected and may include problems
with memory or thinking skills confusion mood changes speech disorders impaired
balance and movement the way the symptoms appear can be used to
differentiate stroke related dementia from Alzheimer’s disease which usually
develops gradually with specific symptoms appearing in a largely typical
order but vascular dementia may also progress
silently in a continuous manner as a result of age-related vascular wear and
tear or any conditions that damage or narrow blood vessels over time such as
high blood pressure high cholesterol diabetes and amyloid deposit these
factors often affect smaller blood vessels deep inside the white matter of
the brain causing small blockages and microbleeds that often go unnoticed to
the patients this is known as cerebral small vessel disease and is the most
common cause of vascular dementia in older adults another cause of vascular
dementia is hypoperfusion of the entire brain this may result from heart
failures hypotension or carotid artery occlusion there is no cure for vascular
dementia but prevention by controlling vascular risk factors such as high blood
pressures can be effective lifestyle changes such as healthy diets quitting
smoking and physical exercise have been proven to be beneficial treatment is by
managing the underlying conditions you
