Following Alzheimer’s disease, Vascular dementia is another common cause of dementia. It is hard to believe for any individual that he is suffering from such a disease which makes him forget even his own home and family. In UK, around 200,000 people are affected by this disease. But experts still have to find out the reason behind the occurrence of this illness. The origins of vascular dementia are still unknown to them.
As explained by Dr Karen Horsburgh, a neuroscientist at Edinburgh University who specialises in the causes of vascular dementia and Alzheimer’s disease “Vascular disease is caused when the blood supply — the vascular system — to and within the brain is disrupted or damaged. If blood cannot reach the brain cells, the cells will eventually die. This can lead to the onset of vascular dementia”.
This illness can happen suddenly at any point of time. It does not give any indication prior attacking an individual. Either a significant stroke, or any of the ageing symptoms can be definitely a reason behind Vascular dementia.
Mini strokes can be also a reason for Vascular dementia. As told by doctors this illness can cause unnoticeable damages to an individual for a small or a longer period of time. But slowly and slowly it can result into a serious disruption of brain functioning.
However Alzheimer’s disease and vascular dementia differs from one another in some ways. Like in vascular dementia, blood vessels are blocked and the general vascular system gets damaged. During such a phase the reduced blood flow can be tested with the help of a special angiograph.
Whereas, while suffering from Alzheimer’s disease, the general cells of brain stop working and they build up amyloid plaque. This is more commonly known as a protein associated with Alzheimer’s disease.
