Most people with a concussion recover quickly and fully. But for some people, symptoms can last for days, weeks, or longer. In general, recovery may be slower among older adults, young children, and teens. Those who have had a concussion in the past are also at risk of having another one and may find that it takes longer to recover if they have another concussion.
Symptoms of concussion usually fall into four categories:
Difficulty thinking clearly
Fuzzy or blurry vision
Sleeping more than usual
Feeling slowed down
Nausea or vomiting
Sleep less than usual
Sensitivity to noise or light
Trouble falling asleep
Difficulty remembering new information
Feeling tired, having no energy
Nervousness or anxietySome of these symptoms may appear right away, while others may not be noticed for days or months after the injury, or until the person starts resuming their everyday life and more demands are placed upon them. Sometimes, people do not recognize or admit that they are having problems. Others may not understand why they are having problems and what their problems really are, which can make them nervous and upset.The signs and symptoms of a concussion can be difficult to sort out. Early on, problems may be missed by the person with the concussion, family members, or doctors. People may look fine even though they are acting or feeling differently.
