The Effects of âWhite Matterâ in the Brain The hypothesis suggests that white matter lesions may lead to disrupted structural connectivity within the brain along what are known as neural “tracks.” These disruptions could then lead to functional deficits, in turn contributing to behavioral impairments.

- The white matter, also known as substantia alba, is a neuron that is made up of extending, myelinated nerve fibers, or axons. It composes the structures at the center of the brain, like the thalamus and the hypothalamus.t is also the myelin that is responsible for the white appearance of the white matter. 60 percent of the brain is comprised of white matter. Summary: 1. Grey matter is made up of nerve cell bodies, and white matter is made up of fibers. 2.

Damage to Tiny Blood Vessels in Brain May Raise Alzheimer's Risk Areas of this blood vessel damage, called white matter hyperintensities, are found in the brains of patients with Alzheimer's disease and appear to raise the risk for the condition, the researchers report.

- Mild traumatic brain injury, or concussion, can be defined as a short-lived loss of brain function due to head trauma that resolves spontaneously. With concussion, function may be interrupted while there is no structural damage to the brain.

Brain Damage: Symptoms, Causes, Treatments Brain damage is an injury that causes the destruction or deterioration of brain cells. In the U.S., every year, about 2.6 million people have some type of brain injury -- whether as a result of trauma, stroke, tumor, or other illnesses, according to the Brain Injury Association of America.

Brain Diseases White matter signal changes on the MRI essentially means that on the MRI, the white matter showed some scattered bright spots. White matter in the brain refers to the fiber tracts that carry information to and fro from the brain. My first question when somebody asks me what next and what does this mean is to ask them why was the MRI done in the first place.

Brain Injuries Such injuries usually do not involve loss of consciousness (being knocked out). More serious brain injuries may occur with or without a skull fracture as a result of impact trauma. The brain is surrounded by a liquid called cerebrospinal (se-REE-brospy-nal) fluid (CSF). The CSF acts as a cushion to absorb some of the force of impact.

White matter disease exacts heavy toll, increasing risk of stroke, Alzheimer's, dementia More evidence has been accumulated that damage to cognitive areas is widespread from white matter disease. White matter disease is responsible for about a fifth of all strokes worldwide, more than doubles the future risk of stroke, and is a contributing factor in up to 45% of dementias. Unlike Alzheimer's disease, which shrinks the hippocampus causing progressive memory loss, white matter disease is a more diffuse mind-robbing condition that targets small blood vessels deep within the brain's white matter. The disease hardens the tiny arteries, gradually restricting nutrients to white matter -- the connections between brain regions involved in executive abilities such as planning, organizing, problem-solving, and attention.

UC Davis neurology researchers focus on brain's superhighway of connectors White matter is that part of the brain made of cells called ‘axons' that connect one to the other so that nerves can communicate, says UC Davis Alzheimer's Disease Center director Charles DeCarli. White matter enables the brain to operate intact..

Concussion A blow to the head, an injury, a fall, or sudden severe shaking may cause the brain to hit the inside of the skull. If the impact affects the consciousness centers in the brain stem * , then the person with concussion loses consciousness.

White Matter in the Brain White matter is tissue in the brain composed of nerve fibers. The fibers (called axons) connect nerve cells and are covered by myelin (a type of fat). The myelin is what gives white matter its white color. Myelin speeds up the signals between the cells, enabling the brain cells to quickly send and receive messages.

Brain white matter lesions in migraine: whatâs the meaning? Migraine has been associated with structural brain damage. Several studies have reported an association between migraine and brain white matter lesions or clinically silent infarct-like abnormalities in the posterior circulation territory. The origin of these lesions is still unclear.

What Does a White Spot on a Brain MRI Mean? A white spot on a brain MRI, referred to as white matter or a brain lesion, shows an area of injury or disease, but can result in a number of diagnoses, according to the Mayo Clinic. The potential diagnoses range from harmless and controllable to possibly life threatening. Continue Reading.

Concussion A concussion is a minor or less severe type of brain injury, which may also be called a traumatic brain injury. A concussion can affect how the brain works for a awhile. It may lead to headaches, changes in alertness, or loss of consciousness. A concussion can result from a fall, sports activities, or car accidents. A big movement of the brain (called jarring) in any direction can cause a person to lose alertness (become unconscious). How long the person stays unconscious may be a sign of how bad the concussion is.

- Damage to the brain from a brain injury can result in physical, emotional, psychological and practical problems. Suddenly, one's whole life expectations may change.Career prospects, relationships with family and friends, personal goals and ambitions may change in an instant. brain injury or 'Traumatic Brain Injury' can be defined as 'damage to living brain tissue that is initially caused by external mechanical forces'. This contrasts with brain injury caused by internal events such as blood vessels bursting (strokes), growth of tumours, viruses or development of diseases.

Protecting the Brain from a Glutamate Storm Moreover, glutamate can serve as a source of energy for the brain cells when their regular energy supplier, glucose, is lacking. However, when its levels rise too high in the spaces between cells—known as extracellular spaces—glutamate turns its coat to become a toxin that kills neurons.ead injury or stroke can cause a surge in glutamate, leaving damaged neurons in its wake. But a new method may help keep the chemical messenger in check. When a stroke or head injury releases a flood of the chemical messenger glutamate, the excess glutamate leaves damaged neurons in its wake.

- The cortex of the brain which contains nerve cell bodies. The gray matter is in contrast to the white matter, the part of the brain that contains myelinated nerve fibres. The gray matter is so named because it in fact appears gray. The white matter is white because that is the colour of myelin, the insulation covering the nerve fibres.

Top 30 Doctor insights on: Punctate Foci Subcortical White Matter See below: It means you may have tiny lesions in white matter where nerve fibers extend away from nerve cells. The increased signals may indicate areas of injury due to ischemia (lack of oxygen) or other causes. They are too small and few in number to be significant.

- Brain injury – Damage to the white matter brain tissue. Periventricular leukomalacia, or PVL, is a type of brain damage that involves the periventricular white matter of the brain.Damage to the white matter results in the death and decay of injured cells, leaving empty areas in the brain — called lateral ventricles, which fill with fluid (a condition called leukomalacia).eriventricular Leukomalacia, or PVL. The brain’s white matter serves a vital purpose within the human body in that it transports impulses to gray matter cells. When a person suffers a periventricular leukomalacia injury, these functions are impaired.

White matter disease of the brain: what do we know about it? Should I worry? A point to remember here is that these white matter changes visualized on the brain MRI can be seen in many different diseases of the brain-diseases as diverse as leukodystrophies, nutritional deficiencies, toxic drug exposures, vascular dementia and multiple sclerosis (MS).

People Who Suffer Depression And Anxiety After A Traumatic Brain Injury May Have Damaged White Matter Similarly, concussion-related anxiety was linked to the impaired functioning of white matter in an area of the brain called the vermis that is believed to be involved in the regulation of our fear responses. Unfortunately, no smoking gun was found for those with irritability.

- White Matter Changes. White matter change is a very common finding on an MRI scan. Frequently, these changes are seen in patients who have/have had hypertension, stroke, migraine headaches, or other medical conditions. As the brain ages, we tend to see a change in appearance around the fluid filled spaces (the ventricles).
