Acne is extremely common and should be addressed to minimize its impact on self-esteem.

Injuries are very common among adolescents, and sports-related and motor vehicle injuries are most frequent. Motor vehicle crashes, other unintentional injuries, homicide, and suicide are the four leading causes of death among adolescents. Concussions, or brain injury resulting from head trauma, are common, particularly among athletes (see also Sports-Related Concussion). Adolescents who suffer a head injury should be evaluated by a professional who is experienced in the evaluation and treatment of this type of injury. After a concussion, adolescents should be given time to recuperate before returning to regular activities, including use of electronic devices, schoolwork, and sports. Re-entry into these activities should be supervised by a knowledgeable adult.
