Adults and children with a suspected<unk>  require a medical assessment to confirm the diagnosis of<unk>  and rule out more serious head injuries. After life-threatening head injuries, injuries to the cervical spine, and neurological conditions are ruled out, exclusion of neck or head injury, observation should be continued for several hours. If repeated vomiting, worsening headache, dizziness, seizure activity, excessive drowsiness, double vision, slurred speech, unsteady walk, or weakness or numbness in arms or legs, or signs of basilar skull fracture develop, immediate assessment in an emergency department is needed. Observation to monitor for worsening condition is an important part of treatment. People may be released after assessment from their primary care medical clinic, hospital, or emergency room to the care of a trusted person with instructions to return if they display worsening symptoms or those that might indicate an emergent condition ("red flag symptoms") such as change in consciousness, convulsions, severe headache, extremity weakness, vomiting, new bleeding or deafness in either or both ears. Education about symptoms, their management, and their normal time course, may lead to an improved outcome. Rest and return to physical and cognitive activity Physical and cognitive rest is recommended for the first 24–48 hours following a<unk>  after which injured persons should gradually start gentle low-risk physical and cognitive activities that do not make current symptoms worse or bring on new symptoms. Any activity for which there is a risk of contact, falling, or bumping the head should be avoided. Low-risk activities can be started even while a person has symptoms, as long as the activity does not worsen existing symptoms or bring on new<unk>  symptoms. Resting for longer than 24–48 hours follow<unk>  has been shown to be associated with longer recovery. Return-to-school The resumption of low-risk school activities should begin as soon as the student feels ready and has completed an initial period of cognitive rest of no more than 24–48 hours following the acute injury. Long absences from school are not suggested, however, the return to school should be gradual and step-wise. Prolonged complete mental or physical rest (beyond 24–48 hours after the accident that lead to the<unk>  may worsen outcomes, however, rushing back to school before the person is ready, has also been associated with longer-lasting symptoms and an extended recovery time. Students with a suspected<unk>  are required to see a doctor for an initial medical assessment and for suggestions on recovery, however, medical clearance is not required for a student to return to school. Since students may appear 'normal', continuing education of relevant school personnel may be needed to ensure appropriate accommodations are made such as part-days and extended deadlines. Accommodations should be based on the monitoring of symptoms that are present during the return-to-school transition including headaches, dizziness, vision problems, memory loss, difficulty concentrating, and abnormal behavior. Students must have completely resumed their school activities (without requiring<unk> -related academic supports) before returning to full-contact sports. Return-to-sport For persons participating in athletics, it is suggested that participants progress through a series of graded steps. These steps include: * Immediately after injury: 24-48 hours (maximum) of relative physical and cognitive rest. *Stage 1: Gentle daily activities such as walking in the house, gentle housework, and light school work that do not make symptoms worse. No sports activities. * Stage 2: Light aerobic activity such as walking or stationary cycling * Stage 3: Sport-specific activities such as running drills and skating drills * Stage 4: Non-contact training drills (exercise, coordination, and cognitive load) * Stage 5: Full-contact practice (requires medical clearance) * Stage 6: Return to full-contact sport or high-risk activities (requires medical clearance) At each step, the person should not have worsening or new symptoms for at least 24 hours before progressing to the next. If symptoms worsen or new symptoms begin, athletes should drop back to the previous level for at least another 24 hours. Intercollegiate or professional athletes, are typically followed closely by team athletic trainers during this period but others may not have access to this level of health care and may be sent home with minimal monitoring. Medications Medications may be prescribed to treat headaches, sleep problems and depression. Analgesics such as ibuprofen can be taken for headaches, but paracetamol (acetaminophen) is preferred to minimize the risk of intracranial hemorrhage. Concussed individuals are advised not to use alcohol or other drugs that have not been approved by a doctor as they can impede healing. Activation database-guided EEG biofeedback has been shown to return the memory abilities of the concussed individual to levels better than the control group. About one percent of people who receive treatment for mTBI need surgery for a brain injury. Return to work Determining the ideal time for a person to return to work will depend on personal factors and job-related factors including the intensity of the job and the risk of falling or hitting one's head at work during recovery. After the required initial recovery period of complete rest (24–48 hours after the<unk>  began), gradually and safely returning to the workplace with accommodations and support in place, should be prioritized over staying home and resting for long periods of time, to promote physical recovery and reduce the risk of people becoming socially isolated. The person should work with their employer to design a step-wise "return-to-work" plan. For those with a high-risk job, medical clearance may be required before resuming an activity that could lead to another head injury. Students should have completed the full return-to-school progression with no academic accommodations related to the<unk>  required before starting to return to part-time work.
