[INEEDHELP!]

My brother has been suffering from a degenerative condition for about a year now. At first the symptoms were ringing in the ears, slight loss of vision, speech impediments, sever headaches on the right side of his head, and a very slowed cognitive state.
we went to the hospital however no one was able to determine anything and did not take him very seriously. He went to multiple other doctors and none were capable of diagnosing a condition or cause of his symptoms. Eventually he got an EEG scan and the doctor said that he could clearly discern a hyperactivity in portion of his brain that my brother was describing pain, however this doctor's solution was meditation. My brother's conditions are to the point where he cannot function and is in constant pain.His motor skills are severely inhibited and he is almost constantly asleep in terms of cognitive function. He is forgetting almost everything constantly. What do we do?? There has to be someone who is willing to take this seriously.
