Dr Richard Schulze who cured the incurables and people with strokes, brain cancer and brain injuries has a chapter on strokes and head injuries in his save your life manual I would be happy to send you if you send me an email address so I can attach it. and get it back to you (you cannot send on this site but need to do it via email)
He mentioned cayenne and ginger as very important and talks about them and doses etc. He speaks of some successful case histories of brain injury that reversed. He also mentioned hot and cold showers to the herbs and brain oxygen increasing herbs. Also I know when they did ear surgery on me they cut a nerve and I lost the taste buds in half my mouth (the ones on that side) but I no longer notice this..ei ther the nerve regenerated or the other side took over. I feel for him. I think you should also add gota kola which in studies with rats has regenerated nerves and they are now doing a study to see if it reverses neuropathy in diabetics be sure it is an organic tincture and take at least 5 or 6 times a day. Also take doctor Christopher's 9 herb formula..http://www.herballegacy.com/Relax_Eze.html and look around his site
It is one part of each herb mentioned here plus the addition of the one he used and has in his book that his heirs apparently removed due to the difficulty and expense of this herb--called lady's slipper. It is also called nerve root ,type bulk herb organic and the herb you need into a search engine and then make a tincture following the directions here

Also remind me to send you the chapter on brain cancer in case anything in there is of help
also remind rime to send you info on seizures. check out what Dr Christopher who was an expert on healing seizures has to say at his site herballegacy.com linked above look around there at seizures epilepsy nerves and so forth.
If using his b and b formula as Schulze recommends, be sure it is in the form of an organic tinctures not capsuled conventional herbs as it is usually now sold by his heirs.
also get the person on the full incurables program by Dr Richard Schulze, a 100% raw vegan whole food diet and green smoothies. I just wrote on green smoothies here I can look up the formula for you if you email me and need it; and want to make it yourself.
