Traumatic brain injuries are a common type of head injury that may be suffered in a variety of different accidents, including car accidents, sporting accidents, swimming pool accidents, and construction accidents. The category “traumatic brain injury” encompasses a wide variety of head injuries, ranging from the minor concussion to the penetrating brain injury (where an object actually penetrates the skull to injure the brain tissue). Traumatic brain injuries often carry significant long-term side effects, including dizziness, seizures, cognitive impairment, vision problems, slurred speech, nausea or vomiting, extreme fatigue and more. Symptoms vary from person to person, but it is always important to consult a doctor immediately if you have suffered a head injury in an accident.
