Neurology/Arteriovenous Malformation
Brain A.V.M. (Arterio Venous Malformation): a mass of extraneous blood vessels that forms in a being's brain at the first stages of that being's first stages of fetal development. An existent A.V.M., in an individual's brain, makes the experience of a hemorrhagic stroke much more likely; however, instead of having the stroke permanently affect the individual, he or she, after approximately 3-5 weeks of bed rest, can return to normal life, as though nothing happened.
After several strokes have occured, a Brain A.V.M. can be required to be treated, necessarily.
