Why do I feel fatigued with traumatic brain injury?

Dr. Darria Long Gillespie, MD

It's not unusual to feel sleepier than normal after having a concussion--some people also may feel that they have confusion, memory loss, or just are thinking as if they're "in a fog".  
Usually, symptoms will start to improve around one week, and resolve after 2-3 weeks.  You can help your symptoms by taking this time to get plenty of sleep, avoiding heavy physical activity, easing your load of mental activity (especially things that require a great deal of concentration), remaining well hydrated, and avoiding alcohol.  
A concussion is your brain's way of telling you it's been injured--just the same as a bruise or cut on your skin. Listen to your concussion symptoms and modify your lifestyle as long as you have them--giving your brain the important time that it needs to heal and get back to normal.
