AFTERMATH EFFECT OF THE IMPACT

A lovely friend of mine from childhood whom we both attended the same secondary school, recently had an accident on his way back from work on his bike. They were two young men on the bike returning home from work before the impact, but it was so unfortunate that the other young man with my friend lost his life two days after the accident. And as for my friend, his body was burnt, he lost cognitive ability, he was on coma but has start regaining consciousness.
The aftermath effect of the accident was very challanging, because the impact caused him to have traumatic brain injury, this has resulted to confusion, disorientation, lost of memory, lost of speech, inability to reason. Although, a therapist has been with him, helping him to regain memories, speaking ability, his orientation. But, i still wish to ask if any body have a good alternative for his quick recovery.
