What is the treatment for brain lesions?

Treatment for brain lesions depends upon the specific diagnosis of the brain lesion.

Can brain lesions be prevented?

Many brain lesions are neither preventable nor predictable. However, general guidelines for health maintenance may help prevent some brain lesions. The same recommendations to help prevent heart disease also are appropriate to help prevent strokes:

  • Don't smoke
  • Control high blood pressure, high cholesterol, and diabetes
  • Always wear a helmet when participating in activities where the head is exposed to danger (for example, riding a bicycle or motorcycle, skiing, skateboarding, and rollerblading).
  • Avoiding radiation and environmental toxins may reduce the chances for brain cancer development.

What is the prognosis for brain lesions?

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 is frequently permanent. However, some people can reduce their symptoms with rehabilitation training and medication.

A few brain lesions may have a good prognosis if only a small amount of less vital brain tissue is involved and/or early interventions are successful (for example, surgical removal of a small benign tumor, early effective antimicrobial treatment of meningitis, or transient ischemic attack [TIA or mini-stroke]).

Unfortunately, some brain lesions are relentless, progressive and ultimately have a poor prognosis (for example, Alzheimer's disease).
