Head injuries are different and healing can be both short term and long term in nature. When my wife went into ICU with spinal issues the same day a girl went in from a motorcycle wreck with head injuries. Three months later my wife was transferred to spinal rehab. The girl was still in a coma. A month after my wife was in rehab the girl showed up for rehab and was conscious.
There was also a guy my wife used to care for in the nursing home. He fell off the hood of a moving car and was a head injury. Last time we saw him he was somewhat able to move around but had cognitive issues that made living outside the nursing home impossible. One day I was taking my wife to outpatient therapy and I said hey look it's Buck. Sure enough a year later he was living alone in an apartment. We were very amazed at his progress. With head injuries improvements are far more likely to still happen long term than with spinal issues once past the six month mark.
