Overview
Balo disease, also known as concentric sclerosis or Balo concentric sclerosis, is a type of multiple sclerosis that is rare and very rapidly progressive. The disease can be best characterized by the alternating bands of intact and lost myelin (the fatty substance that encapsulates and protects the brain’s nerve fibers) throughout different parts of the brain or brain stem, as detected on MRI. While it normally is identified in adults, children may also contract the disease.
