My uncle was diagnosed neurosarcoidosis in his 52, at first he just felt headache and often confused about what we say. Later it get worse and worse, he cannot hear, cannot speak or see clearly. But he could still speak with us, just in his own way. We’ve took him to a therapy, and doc prescribed corticosteroids and other medicines for him. Now he is 65 and to our surprise his symptoms seems gone away. I mean his like a normal old man instead of a patient. His doc said that it’s a remission. Some people just go on to live normal lives as time pass by. Good luck to you!
