Thank you for posting your query at DoctorSpring.com.
I appreciate your concern for your boyfriend, and thank you for providing the detailed information.
I am glad to note that he is functionally well and is doing well in his professional life too, despite his early childhood problems and possible brain damage due to lack of oxygen.
Yes, physiotherapy and occupational therapy would be very useful for him in further recovery and improving his fear. His balance would also improve.
In addition, using anti-anxiety medications would also help.
I hope it is helpful. Please get back if you have any additional queries.
