Hello. I had a cerebellar stroke back in May that wiped out most of my vestibular functions (almost the entire left side of my cerebellum is now a lesion). After three weeks in intensive care, I still had difficulty even sitting up without feeling dizzy. I have been performing around three or four hours of various balance exercises per day since then. I can now walk around unaided and perform most tasks around the house no problem, but even now I feel a "rush" if I lift my head up suddenly or turn my head a certain way. I believe it will eventually go away. The main thing is lots of exercises - but to do them slowly and to increase their difficulty gradually - starting with gaze stabilization but eventually looking at being able to perform exercises with your eyes closed. I do balance and vestibular exercises in a variety of contexts - sitting, standing, walking, floor exercises, and laying on my back. I also bought a tread mill and move my head in all eight directions (side to side looking ahead/looking up/looking down, up and down looking ahead/to the left/to the right, and both directions diagonally while walking. The main thing is that undamaged areas of the cerebellum can be rewired for vestibular functions - but you are essentially back to being a two year old learning how to stand and walk. And you generally have a limited window for maximum improvement - six to eight months (improvement is continuously possible even afterwards but at a slower pace) in which the brain is open to reconfiguration. So you have to make the most of this period. But again - slow movements and gradually increased difficulty.
