Symptoms of concussions include confusion, memory loss and headache. Symptoms are often subtle and may not show up right away. They can also last for weeks or longer, according to Mayo Clinic.
In addition to the symptoms listed above, which are common to all concussions, other possible signs of a concussion include temporary loss of consciousness, dizziness, nausea, ringing in the ears, vomiting, slurring of speech, fatigue, a dazed appearance and a delay in answering questions. Some of these symptoms may appear immediately after the concussion, while others may appear hours or even days later, as stated by Mayo Clinic.
Delayed concussion symptoms include smell and taste disorders, sleep disturbances, depression, sensitivity to noise and light, irritability, memory and concentration issues and psychological problems. Small children with concussions may also present with excessive crying or a disinterest in favorite playthings. If there is any question of a concussion, it is wise to seek medical attention within a day or two of the injury. Emergency care should be sought immediately in cases of repeated vomiting, a progressively worsening headache, seizures, large bumps or bruises anywhere other than the forehead on children, sudden changes in behavior and slurring in speech, as noted by Mayo Clinic.
