The Memory Quiz Was Developed By Dr Gary Small of the UCLA Longevity Center. Learn about Dementia and Many of its Various Forms and Subtypes. What causes vascular dementia? Learn more: Key Types of Dementia, Mixed Dementia.

Find out more about vascular dementia and what causes it.

They have several symptoms and characteristics that overlap, but there are also some clear differences between the two. People with vascular dementia may have an exceptionally hard time analyzing a problem and developing an effective solution. Instea people with vascular dementia can have different signs, depending on the area of the brain that’s. Vascular dementia , also known as multi-infarct dementia is the second most common cause of dementia in older people.

In the human brain there’s both white and gray matter. For those with Alzheimer’s , gray matter is more largely affecte while white matter tends to be targeted within vascular dementia. Based on this distinction, both types of dementia result in cognitive impairments, however, vascular dementia can also influence movement.

Clinically Proven to Naturally Protect Against Dementia.

While Alzheimer’s can cause memory issues. Early and middle stages of vascular dementia. Some symptoms may be similar to those of other types of dementia. Stroke, small vessel disease, or a mixture of the two can cause vascular dementia.

The second most common form, vascular dementia , has a very different cause — namely, high blood pressure. As we stated before, there are early, middle, and late stages of dementia , but there are is also early onset. A network of blood vessels called the vascular system supplies the brain with oxygen, allowing the brain to function properly. If the vessels supplying the brain.

Neuroimaging is not routinely available in developing countries, which influences the accuracy of VaD detection and the confirmation of cases of mixed dementia. Other, less common types include Lewy body dementia and frontotemporal degeneration (FTD). It's caused when decreased blood flow damages brain tissue. Blood flow to brain tissue may be reduced by a partial blockage or completely blocked by a blood clot. Alzheimer’s disease is the most common form of dementia , accounting for approximately two-thirds of all cases.

Symptoms of vascular dementia may develop gradually. Vascular disease occurs where blood vessels are damaged and the supply of oxygen is at risk. If oxygen supply fails in the brain, brain cells are likely to die leading to a series of mini strokes (infarcts) and possible vascular dementia.

These changes can happen suddenly or begin mildly and get worse over time. It's rare in people under 65. The additional presence of vascular disease in the brain often makes symptoms of other brain diseases worse.

Age is the biggest risk factor for vascular dementia. Dementia is caused by diseases, the most common being Alzheimer’s.
