Concussion, also known as minor head trauma, is the most common type of traumatic brain injury. It is typically defined as a head injury with a temporary loss of brain function. Symptoms include a variety of physical, cognitive, and emotional symptoms, which may not be recognized if subtle. A variety of signs accompany concussion including headache, feeling in a fog, and emotional changeability. Physical signs (such as loss of consciousness or amnesia), behavioral changes (such as irritability), cognitive impairment (such as slowed reaction times), or sleep disturbances.
Headaches that occur after a concussion may feel like migraine headaches or tension-type headaches. Most headaches are tension-type headaches, which may be associated with a neck injury that occurred at the same time of the head injury.
