Notes

Cognitive difficulties – Concussions can impact one’s ability to think or concentrate, resulting in a decreased ability to process thoughts and directions. This may lead to difficulty learning new information.
Dizziness/motion sensitivity – When the vestibular system is affected, the result can be difficulties adjusting to space and motion, including a feeling of being carsick. Vestibular dysfunction may affect balance, equilibrium, and coordination as well.
Fogginess – Perhaps the most difficult symptom to define, the feeling of fogginess often leads one to feel one step behind themselves, or detached. Fogginess may increase when in busy environments, such as grocery stores or school cafeterias.
Nausea or vomiting – While vomiting immediately after the injury may be a sign of a more serious neurological injury, many people experience nausea and vomiting in the days, and sometimes weeks, following a concussion. Sometimes this is related to vestibular dysfunction, but can also be associated with migraine.
Fatigue or feeling lethargic – Many people feel fatigued, particularly toward the end of a long day, when recovering from concussion. While taking naps may seem like a good idea, the best way to combat fatigue is to keep a regulated sleep schedule and to obtain quality sleep at night.
