Full Answer

Some symptoms do not appear for several days or even weeks after the head trauma, Mayo Clinic reports. These include sensitivity to noise and light, concentration and memory difficulties, irritability and personality changes. Depression, sleep problems and issues with taste and smell are also common symptoms.

Babies and toddlers cannot communicate how they feel, so parents must watch for concussion symptoms, Mayo Clinic advises. Symptoms may include listlessness, loss of interest in favorite toys, appearing dazed, irritability, excessive crying and sleep disturbances. It is recommended parents call a doctor if a toddler or infant receives more than a light bump on the head.

Emergency medical help should be sought if an adult or child suffers a head injury and has symptoms that get worse over time, Mayo Clinic stresses. Other serious symptoms requiring immediate medical care include losing consciousness for more than 30 seconds, seizures, changes in physical coordination, ongoing confusion, repeated vomiting and vision changes.

Athletes who experience head trauma should be evaluated by a health care professional before playing again, Mayo Clinic says. Children and adults should not play sports on the same day as the head injury.
