What does multiple lesions on the brain mean?
Stroke, vascular injury, or impaired supply of blood to the brain is perhaps the leading cause of lesions on the brain. Multiple sclerosis, or MS, is a disease where brain lesions are located in multiple sites of the brain. Those suffering from MS have significant problems with motor and sensory functions.
Are brain lesions serious?
A brain lesion may involve small to large areas of your brain, and the severity of the underlying condition may range from relatively minor to life-threatening.
What is multifocal white matter lesions?
Infectious disorders Progressive multifocal leucoencephalopathy (PML) is caused by reactivation of latent JC polyomavirus in the immunosuppressed and is a multifocal demyelinating white matter disease. It causes confluent white matter lesions on MRI which do not cause mass effect or enhance.
Are brain lesions considered brain damage?
A lesion is an area of tissue that has been damaged through injury or disease. So a brain lesion is an area of injury or disease within the brain. While the definition sounds simple, understanding brain lesions can be complicated.
Can you have brain lesions and not have MS?
Although MRI is a very useful diagnostic tool, a normal MRI of the brain does not rule out the possibility of MS. About 5 percent of people who are confirmed to have MS do not initially have brain lesions evidenced by MRI.

Can brain lesions be cured?
Brain lesion treatment depends on the cause. Some lesions, such as infections and cancer, can be treated with medication with the goal of a complete cure. Vascular malformations may need to be surgically treated to prevent a rupture.
Can brain lesions go away?
The prognosis for surviving and recovering from a brain lesion depends upon the cause. In general, many brain lesions have only a fair to poor prognosis because damage and destruction of brain tissue are frequently permanent. However, some people can reduce their symptoms with rehabilitation training and medication.
Do brain lesions always mean MS?
How fast does MS progress after first symptoms?
Most symptoms develop abruptly, within hours or days. These attacks or relapses of MS typically reach their peak within a few days at most and then resolve slowly over the next several days or weeks so that a typical relapse will be symptomatic for about eight weeks from onset to recovery.
What is the average life expectancy with MS?
Median life expectancy for all patients with MS was 74.7 years, compared with 81.8 years in the general population (figure 1A). Median survival from disease onset of MS was 40.6 years compared with 54.6 years in the general population (figure 1B).
Can a brain lesion turn into a tumor?
A brain tumor is a specific type of brain lesion. A lesion describes any area of damaged tissue. All tumors are lesions, but not all lesions are tumors. Other brain lesions can be caused by stroke, injury, encephalitis and arteriovenous malformation.
What are brain lesions?
Brain lesions are a type of damage to any part of brain. Lesions can be due to disease, trauma or a birth defect. Sometimes lesions appear in a specific area of the brain. At other times, the lesions are present in a large part of the brain tissue. At first, brain lesions may not produce any symptoms.
What causes multifocal white matter lesions on Mr?
Multifocal white matter lesions There is a long differential diagnosis for multifocal white matter lesions on MR. The most common causes are prominent Virchow-Robin spaces, white matter ischemic change, and multiple sclerosis, but many other causes have been reported.
