What are the Signs and Symptoms of Concussion?
Most people with a concussion have a good recovery from symptoms experienced at the time of the injury. 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||Headache
Fuzzy or blurry vision
|Irritability||Sleeping more than usual|
|Feeling slowed down||Nausea or vomiting
|Sadness||Sleep less than usual|
|Difficulty concentrating||Sensitivity to noise or light
|More emotional||Trouble falling asleep|
|Difficulty remembering new information||Feeling tired, having no energy||Nervousness or anxiety|
Some 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 their problems and how the symptoms they are experiencing are impacting their daily activities.
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.
