Do brain lesions always mean MS?
An “average” number of lesions on the initial brain MRI is between 10 and 15.
However, even a few lesions are considered significant because even this small number of spots allows us to predict a diagnosis of MS and start treatment..
Do white spots on the brain mean MS?
The role of MRI in diagnosing MS If you have symptoms of MS, your doctor may order an MRI scan of your brain and spinal cord. The images produced allow doctors to see lesions in your CNS. Lesions show up as white or dark spots, depending on the type of damage and the type of scan.
What does white matter on a brain MRI mean?
White matter disease is commonly detected on brain MRI of aging individuals as white matter hyperintensities (WMH), or ‘leukoaraiosis.” Over the years it has become increasingly clear that the presence and extent of WMH is a radiographic marker of small cerebral vessel disease and an important predictor of the life- …
Can stress cause white matter lesions?
The researchers discovered that chronic stress generates myelin-producing cells and fewer neurons than normal, resulting in an excess of myelin, and white matter, in some areas. White matter is made up of fibers that connect neurons to each other, so regions of the brain can better communicate.
Can white matter lesions in the brain be nothing?
White matter lesions observed on brain MRI are usually characteristic and occur in specific areas including the corpus callosum and pons. “However, in many cases, the white matter lesions as isolated observations are nonspecific” and could be due to MS or another cause, explained Drs Lange and Melisaratos.
Does everyone have white matter in the brain?
R. Douglas Fields. “Gray matter” is only one of two types of brain tissue; the other “white matter” is rarely mentioned. Yet white matter makes up half the human brain and has not been thought to be important in cognition or learning outside the context of pathology.
Is white matter disease progressive?
White matter disease is a progressive disorder caused by age-related decline in the part of the nerves (the white matter) that connect different areas of brain to each other and to the spinal cord.
Does white matter lesions mean MS?
“In general, white matter disease causes acute MS symptoms, like numbness and weakness,” Stone says. “Gray matter disease causes progressive symptoms, like fatigue and memory loss. These higher brain functions are called cognitive functions. Most MS disability actually comes from cognitive dysfunction.”

Can depression cause white matter lesions?
Cerebral white matter lesions (WMLs) are thought to result from cerebrovascular brain damage. Within the clinical setting, severity of WML has been related with the presence of depression11-13 and with poor outcome of depression.
How do you treat white matter?
White matter disease doesn’t have a cure, but there are treatments that can help manage your symptoms. The primary treatment is physical therapy. Physical therapy can help with any balance and walking difficulties you may develop.
How do you know if you have white matter disease?
Advances in medical imaging have made white matter disease easier to spot. A magnetic resonance imaging (MRI) test, which takes pictures of the inside of your brain, can show any damage. Changes to white matter will show up super-bright white (your doctor may call this “hyperintense”) on an MRI scan.
What does white matter on brain mean?
In contrast to gray matter, in which the cell bodies of neurons predominate, the term white matter refers to areas of the brain where there is a preponderance of axons coated with myelin. (Axons, which can be up to three feet long, are the longest projections of brain cells and carry a cell’s signal to other cells.)
Are white spots normal on brain MRI?
It allows researchers to “map” pathways in our brain with great accuracy. The finding of a “white matter lesion” in the brain during an MRI is quite common.
What causes white matter lesions on the brain?
Risk Factors Small strokes—the most common cause of white spots on a brain MRI—are often caused by blockages of small blood vessels due to high blood pressure and/or diabetes, while large strokes are usually caused by heart disease or carotid artery disease.
At what age does white matter disease start?
This condition occurs between 12 and 18 months of age and causes deterioration in thinking skills, speech, and coordination. Within 2 years, children can develop gait and posture problems, as well as blindness and paralysis.
How serious is white matter disease?
Summary: 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.
Are white matter lesions normal?
Combining these three studies together, it is clear that small (punctate) white matter lesions are extremely common, they are found in roughly half of the otherwise healthy population in their 40’s, and WML increase with age.
