Rehabilitation of a 16-year-old boy after an injury

Our boy, 16 years old, in April 2020 suffered a traumatic brain injury with a contusion of the brain, there was a fracture of the lower leg. The course of rehabilitation lasted 3 months. After rehabilitation, we were able to walk independently within the room, climb stairs and memorize up to 6 words at the time of speech, although before that we spoke only simple monosyllabic words and memorized only one word. Many thanks to the doctors, we hope for further progress.
