What Are the Different Types of Brain Injuries?
Brain injuries vary in severity. A person could walk away from an impact to the head, not realizing they need medical care, and die hours later. Whenever a person is struck on the head, a full medical assessment should be performed as quickly as possible. The types of brain injuries, as listed by the Centers for Disease Control (CDC), include:
Mild
An impact on the head can cause the brain to move within the skull, damaging brain cells. The symptoms of a concussion include sensitivity to light, dizziness, lack of energy, fatigue, nausea, vision problems, memory problems, anxiety, irritability, emotional difficulties, sleep problems, and headaches.
Moderate
A moderate TBI can lead to a lifetime of challenges, health problems, and the need for ongoing treatment. The symptoms include loss of consciousness, persistent headache, vomiting, nausea, convulsions, seizures, inability to wake up, loss of coordination, confusion, agitation, aggressive behavior, slurred speech, or coma.
Severe
A severe TBI brings a set of very frightening symptoms, including a severe headache, loss of vision, slurred speech, convulsions, one pupil dilated, vomiting, numbness in limbs, lack of coordination, agitation, confusion, loss of consciousness, coma, vegetative state.
