MRI is able to image the structure of the brain, which changes in dementia, to a very high resolution. For example, a characteristic sign of Alzheimers disease is atrophy (shrinking) of a brain region called the hippocampus. This can easily be seen on an MRI scan and is currently used to aid diagnosis.
Can you see signs of Alzheimers on an MRI?
Brain scans CT and MRI scans, which reveal the anatomic structure of the brain, are used to rule out such problems as tumor, hemorrhage, stroke, and hydrocephalus, which can masquerade as Alzheimers disease. These scans can also show the loss of brain mass associated with Alzheimers disease and other dementias.
Can you see vascular dementia on an MRI?
Magnetic resonance imaging (MRI). MRI s are generally the preferred imaging test because MRI s can provide even more detail than CT scans about strokes, ministrokes and blood vessel abnormalities and is the test of choice for evaluating vascular dementia.
What is the difference between vascular dementia and dementia?
Vascular dementia is a common type of dementia caused by reduced blood flow to the brain. Its estimated to affect around 150,000 people in the UK. Dementia is the name for problems with mental abilities caused by gradual changes and damage in the brain.
What is the life expectancy of someone with vascular dementia?
On average, people with vascular dementia live for around five years after symptoms begin, less than the average for Alzheimers disease. Because vascular dementia shares many of the same risk factors as heart attack and stroke, in many cases, the persons death will be caused by a stroke or heart attack.
Can vascular dementia progress rapidly?
Vascular dementia will usually get worse over time. This can happen in sudden steps, with periods in between where the symptoms do not change much, but its difficult to predict when this will happen. Home-based help will usually be needed, and some people will eventually need care in a nursing home.
