Having lived over 21 years with a severe acquired head injury this has given me back my life. The symptoms I had were so severe I was bed ridden for 90% of those years unable to walk and many times unable to communicate. I spent the first 19 years in full darkness with all windows covered with total blackout. Symptoms disorder sensation between hot and cold, severe photophobia, headaches, nausea, paroxysmal vomiting, permanent vertigo, epilepsy, cataplexy, narcolepsy, disorientation, sensory/motor skills, poor balance, acoustic nerve change, decreased hearing, constant tinnitus. visual disturbance. I fractured my pelvis twice over 2 years. I am 69. I am starting to live again
