What do we know about hypertrophic olivary degeneration?

Not very much, which is why we created the foundation. There is no cure at present, only the treatment of symptoms. We know that the majority of people diagnosed with this rare degenerative brain disease have had a previous brain bleed, brain tumor, brain injury, brain surgery, or cavernous malformation in the cerebellum, brain stem or in the Guillain-Mollaret Triangle. However, we are aware of a few cases that are idiopathic, with no prior brain injury. It is commonly accepted that the inferior olive(s) first swell (hypertrophy) and then atrophy (degeneration). There are two inferior olives in the brainstem. HOD can occur in one or both olives. Learn more here!
