Protect the brain while it heals from a concussion
After a brain injury, recovery hinges on protecting the brain: above all avoid another concussion, since repeated injuries compound damage. Cut sugar and alcohol, consider hyperbaric oxygen therapy early and omega-3s as supports, and screen over time for Irlen syndrome — a visual-processing problem that's common after concussions and can emerge later.

A concussion or traumatic brain injury heals best when the brain is shielded from further insult, and the single most important step is avoiding another concussion — repeated head injuries compound the damage and stall recovery, so protective measures against more head trauma come first.
Several other levers support healing. Cutting sugar and avoiding alcohol both protect recovery (alcohol in particular is neurotoxic and impedes brain healing). Increasing oxygen delivery to injured tissue is the rationale behind hyperbaric oxygen therapy, which is worth pursuing early in the timeline rather than late. Omega-3 fatty acids support neuronal membrane structure and may reduce inflammation, making them a reasonable dietary support during recovery. Finally, keep watch over time for Irlen syndrome — a visual-processing problem that is common after concussions and can surface gradually rather than immediately; getting screened for it if reading or visual symptoms appear is part of a full recovery picture. These are supports to coordinate with proper medical care after a head injury, not a substitute for it.
