Demyelination: What Is It and Why Does It Happen? Viral demyelination occurs with progressive multifocal leucoencephalopathy (PML). PML is caused by the JC virus. Myelin damage can also occur with alcoholism, liver damage, and electrolyte imbalances. Hypoxic-ischemic demyelination occurs due to a lack of oxygen or vascular disease in the brain.

Vascular Dementia Related dementias share some common symptoms. Vascular changes that start in brain areas that play a key role in storing and retrieving information may cause memory loss that looks very much like Alzheimer's disease. Inadequate blood flow can damage and eventually kill cells anywhere in the body.

Causes Causes of vascular dementia. Vascular dementia is caused by reduced blood flow to the brain, which damages and eventually kills the brain cells. In some people, the damage to the brain may be caused by Alzheimer's disease in addition to one of these conditions. This is known as mixed dementia. Things that can increase your chances of developing vascular dementia in later life include: high blood pressure (hypertension)

Types of Dementia In the past, evidence for vascular dementia was used to exclude a diagnosis of Alzheimer's disease (and vice versa). That practice is no longer considered consistent with pathologic evidence, which shows that the brain changes of several types of dementia can be present simultaneously.

- Vascular dementia is the second most common type of dementia (after Alzheimer's disease), affecting around 150,000 people in the UK. The word dementia describes a set of symptoms that can include memory loss and difficulties with thinking, problem-solving or language. In vascular dementia, these symptoms occur when the brain is damaged because of problems with the supply of blood to the brain. This factsheet outlines the causes, types and symptoms of vascular dementia. It looks at how it is diagnosed and the factors that can put someone at risk of developing it.

Can dementia cause dizziness? Dementia can cause dizziness, particularly if it is vascular dementia, but I do not see dizziness caused by Alzheimer's very often. Dizziness is more commonly associated with vascular dementia because blood flow to the brain is restricted. With Alzheimer's, your loved one's balance may be affected. Balance issues are common with dementia, which may give an observer the impression that the person is suffering from dizziness.

Demyelinating disease Demyelinating disease. A demyelinating disease is any disease of the nervous system in which the myelin sheath of neurons is damaged. This damage impairs the conduction of signals in the affected nerves. In turn, the reduction in conduction ability causes deficiency in sensation, movement, cognition, or other functions depending on which nerves are involved.
