Can you outline the stages of tbi recovery post-trauma?

Traumatic Brain UInjury Recovery:

Early Stages of the TBI Recovery Timeline (0-2 months post-injury) In the initial days and weeks after their TBI, a survivor may remain unconscious for some time. As the swelling in the brain decreases, the survivor should begin to regain awareness and will pass through the first three stages of TBI recovery.

Unfortunately, there isn’t a one-size-fits-all answer. Some patients experience a fast recovery in a short period of time, while others recover more gradually. The good news is that — thanks to neuroplasticity — recovery after brain trauma is possible even for patients with severe injuries. 

Obviously, not all TBI patients recover at the same rate. Generally, patients with more severe brain damage who experienced lengthy loss of consciousness, a coma, or were in a vegetative state need a longer recovery time and may not make a full recovery. Most patients with a mild traumatic brain injury — commonly known as a concussion — recover fully within a few weeks, but some do not recover within the expected two-week to three-month timeframe.
