Give the man a cigar. All to often people with brain injuries are just ignored if amazing recovery doesn't come in the first weeks or months. The truth is, it's a long road back from brain injury, and it takes focused intensive therapy. Think about it. When a child is born, and begins to mature, he gets the focus of adults most of his waking life. Constant attention is paid to "potty training" until the child gets out of diapers. Then there's "pre-school", where the child is constantly engaged by adults getting the learning process started, and preparing the child for ever more intense learning experiences. A person with a brain injury often "forgets" all they learned as a child, those basic skills.
Well, why in the world would any reasonable person think that all of those skills can be re-learned easily with the patient in a room by themselves with no real stimuli for all but 15-30 minutes of "therapy"? If an injured person can eat "some of the time", they almost surely possess the skills required, and only need to be taught and encouraged. The same thing applies to bathroom skills.
The problem is that most "rehabilitation facilities" do not have the staff or the desire to actually do the job. Many of them are poorly run "nursing homes" at best, and basically nothing more than a "dumping ground" (yeah, a sad thing to say) for people that no one wants to take care of anymore. They have a minimal staff, poorly trained, who are only interested in getting through the week and collecting a check. It's far easier for them to practically force feed a patient and change their diaper than it is to actually try to help that patient.
