A person suffered a head injury, was unconscious for a few minutes, and is now sleepy and disoriented. This person likely

has a concussion. It is important for them to seek medical attention immediately as concussions can have serious consequences if not properly treated. Symptoms of a concussion can include drowsiness, confusion, and difficulty concentrating. The person should not be left alone and should be monitored for any worsening symptoms. It is also important for them to avoid activities that could potentially worsen their condition, such as physical or mental exertion.
