Overview
Dementia is a catch-all term for a group of brain disorders that affect memory, thinking, and social skills cruel enough to interfere with daily life. Approximately 50 million individuals across the world suffer from dementia, according to the World Health Organization analysis, and nearly 10 million new cases annually. Numerous different conditions exist under the catch-all term of dementia and numerous different reasons for dementia. Physicians employ a number of tests, such as brain scans, to help diagnose and perhaps identify the reasons for dementia.
Types of Dementia and how they Impact the Brain
Alzheimer’s disease is the most prevalent cause of dementia, experts say, responsible for 60 to 80 percent of all cases. Scientists continue to work to identify the precise cause of Alzheimer’s, but it could be caused by an abnormal accumulation of proteins that ruin brain cells located in the front and sides of the brain. The damage and eventual death of these brain cells, or neurons, lead to the oversized areas of the brain to shrink.
The second most prevalent form is vascular dementia; it is the result of insufficient blood to the brain, a condition referred to as ischemia. Dementia can enlarge as a person grows older, or as the result of a stroke or plaque deposit in the artery supplying the head.
Dementia with Lewy bodies is the result of protein accumulations in neurons, which chip away at the messaging system of the brain as ground symptoms of dementia. Frontotemporal dementia is a collection of dementias that involve the front and sides of the brain as a cause of difficulties with language and behavior. Individuals with Parkinson’s disease tend to accumulate symptoms of dementia.
Several conditions, including strokes and tumors, can cause dementia. Scans of the brain can assist in identifying the causes of a patient’s dementia. Such scans can reveal tumors and verification of blood clots or bleeding associated with strokes, for instance.
Dementia often affects the outer layer of the brain, the cortex. Brain scans can show changes in the cortex that can help doctors to identify the reason for dementia.
Degeneration of the outer cortex layer of the brain is common in most types of dementia. This situation, known as cortical atrophy, can be detectable by a brain scan. A healthy brain cortex appears somewhat wrinkled, with steep “valleys” of tissue unpeeling ridges of tissue. In patients with cortical atrophy, however, the shrinking of brain cells results in ridges becoming thinner and valleys increasing in width. As the neurons perish, fluid-filled cavities within the core of the brain become larger to occupy available space, thus making the fluid-filled spaces become much larger than they originally are. Brain scans can identify and calculate these fluid-filled spaces to help doctors diagnose and measure dementia.
Brain atrophy, also known as cerebral atrophy, is a condition where the brain cells become smaller in size. Brain atrophy may lead to symptoms of dementia in Parkinson’s disease patients; greater tissue shrinkage results in more cognitive decline.
How Brain Scans in Dementia Patients Benefit?
Brain scans can detect changes in brain organization and function related to Alzheimer’s disease and other types of dementia.
Computed tomography (CT) scans and magnetic resonance imaging (MRI) are the predominantly common brain scan types. Physicians depend on CT and MRI brain scans when examining patients with suspected dementia. CT scans produce x-ray pictures of structures inside the brain and can demonstrate evidence of strokes and ischemia, brain atrophy, alterations in the blood vessels, and other maladies that can cause dementia. CT scans and MRI scans may demonstrate loss of brain bulk associated with Alzheimer’s disease and other types of dementia.
MRI scans are able to identify the same issues as CT scans, with MRI scans being upgraded for some issues, including brain atrophy, spoil due to small strokes, or minor patterns of inadequate blood flow of ischemia. 3 Tesla MRI is an amazing kind of MRI that utilizes magnetic fields that are twice as strong as a typical MRI in order to produce very detailed images of the brain in shorter time. Similar to established MRIs, 3 Tesla MRIs have the potential to assist physicians in searching for indicators of stroke, tumors, and other causes of dementia.
Frequently Asked Questions
Q. What are the variables that a brain MRI cost is often based on?
The cost of a brain MRI may vary based on location, facility, and the individual presentation of the scan.
Q. Is the cost of a brain MRI covered by my health insurance plan?
Coverage for a brain MRI can vary widely based on the insurance plan of the patient. The patient will want to contact the insurance company to find out coverage including deductibles, co-pays, and if there is pre-authorization.
Q. Is the cost of a brain MRI the same at each facility or medical center?
Yes, the cost of a brain MRI may be somewhat variable across medical centers. Even for the same indication or problem, there can be cost variation based on where you are located, reputation of the facility, and the quality of the equipment. Therefore, as a patient and consumer, it can be beneficial to do your due diligence and compare prices and quality of the services they are receiving.
Q. Is a brain PET CT scan painful?
No, it’s not a painful procedure, it is a safe and short procedure if all precautions are taken by both sides.
