A brain concussion, also known as a mild traumatic brain injury, occurs when the brain experiences a major force, whether it is an impact force, in which the head experiences a direct blow, or an impulse force, in which the head snaps in one direction without a direct blunt trauma. The brain is surrounded by cerebrospinal fluid, and a large acceleration of the brain can overcome this protective layer and result in impaired neurotransmission and a reduction in cellular metabolism and cerebral blood flow. Fortunately, however, very few concussions result in neuronal cell loss. Symptoms of a concussion are headaches, nausea and vomiting, dilated pupils, confusion, and occasionally a loss of consciousness. These symptoms can last as little as 15 minutes, but the patient still needs careful monitoring for at least several hours after the injury to ensure that the blood loss was not too severe, in which case the patient would require medical attention. The only form of treatment of a concussion is physical and cognitive rest, unless the injury is severe enough to require surgery. Once a patient experiences a concussion, they become more susceptible to subsequent brain injuries.
