This occurs from a mild blow to the head, either with or without loss of consciousness and can lead to temporary cognitive symptoms.
Symptoms may include headache, confusion, lack of coordination, memory loss, nausea, vomiting, dizziness, ringing in the ears, sleepiness, and excessive fatigue.
There’s no specific cure for concussion. Rest and restricting activities allow the brain to recover. This means one should temporarily reduce sports, video games, TV, or too much socializing. Medications for headache pain or other anti-nausea medications can be used for symptoms.
