Timely and considerate care of the arterial and venous systems.
Dementia is a slowly progressive and permanent loss of brain function. It affects things like memory, language, behavior, and judgement.
Vascular dementia is caused by problems with the blood vessels supplying oxygen and nutrients to the brain, which eventually leads to brain cells’ death.
According to MedLine Plus, Vascular Dementia:
Vascular dementia (VaD) is caused by a series of small strokes over a long period.
The UK Care Guide on Vascular Dementia says:
There are two primary reasons why vascular dementia may develop.
Cause 1 – The most common cause is the degeneration of tiny blood vessels deep within the brain, this is called Subcortical Dementia. The tiny bloody vessels can thicken, which in turn reduces the blood supply to those cells, causing them to degenerate and eventually die. The nerve fibres around the affected blood vessels are also harmed, reducing their effectiveness. The disease of the tiny bloody vessels can also affect other areas of the brain, including the base, if blood vessels are blocked here it could cause small infarcts – also known as an ischaemic stroke.
Cause 2 – The second most common cause of Vascular Dementia is following a stroke. Strokes occur when the blood supply to the brain is suddenly cut-off, this can be as a result of a blood clot (an ischaemic stroke) or less commonly, where a blood vessel ruptures and bleeds into the brain (a haemorrhagic stroke).
Around 1 in 5 people who suffer a stroke will develop dementia on top of the side effects of the stroke itself. Most people who have had a stroke will have another and therefore the risk of developing dementia increases with each stroke event as more of the brain becomes damaged.
