Brain Lesions (Lesions on the Brain) (cont.)

Brain Lesions Prognosis

Because of the many different types of brain lesions, the prognosis and outcomes of brain lesions are variable. However, with most brain lesion types, the more brain tissue that is damaged or killed by a brain lesion, the worse the prognosis is for the person. Fortunately, the reverse (little damage, good prognosis) is also generally true, but is mainly limited to lesions caused by mild trauma, strokes that affect a very small brain tissue area, a few rapidly treated infections, and occasionally, a few benign and malignant tumors that are effectively treated.

For some brain lesion types, the damage to some brain tissue is not reversible, so the prognosis may be only fair to good, as long as the person's problems do not progress. Another problem with prognosis is that some brain lesions may recur (for example, strokes and brain cancers), while others (genetic, immune, and plaque forming and brain cell death types exemplified by Huntington's disease, multiple sclerosis, Alzheimer's disease and Parkinson' disease) are simply progressive with no effective definitive cure available. The prognosis in the short term may be good if the symptoms respond to treatment, but the long term prognosis usually is considered to be, at best, fair to eventually poor (perhaps many years after the initial diagnosis), due to their progressive nature.
