![]() The FDA has not cleared or approved any medical products that are intended to diagnose or treat TBI alone without other diagnostic tests or treatments managed by a health care provider. None of the medical devices cleared or approved by FDA are intended to be used alone without the judgment of a health care provider trained to diagnose and treat TBI. In particular, these scans can detect bleeding that resulted from the traumatic injury which requires immediate medical or surgical attention. But tests from these FDA-regulated medical devices can help health care providers rule out some of the more serious brain injuries. Imaging tests, including CT scans and MRI scans, cannot detect all TBIs. This exam evaluates thinking, motor function (movement), sensory function, coordination, eye movement, and reflexes. ![]() Assessment usually includes a neurological exam. While some symptoms of mild TBI can be hard to detect, the Centers for Disease Control and Prevention (CDC), the American College of Rehabilitation Medicine, and some others have published guidelines for diagnosing TBI.Ī medical exam is the first step to diagnose a potential brain injury. Anyone with signs of TBI should receive medical attention as soon as possible. If you have questions about TBI, talk to your health care provider. Moderate and severe TBI can produce more symptoms including: Mild TBIs always involve some degree of brain injury. If a person has the symptoms of TBI after a blow to the head, then the brain has been injured. But when it happens, TBI can range from mild (like a brief change in mental status or consciousness) to severe (like a longer period of unconsciousness or major problems with thinking and behavior after injury).Ībout 75 percent of TBIs (or 3 out of every 4) that occur each year are mild. TBI is often caused by a bump, blow, jolt, or explosive blast to the head, or a penetrating head injury that disrupts the brain’s normal function. Food and Drug Administration continues to study TBI and encourages the development of medical devices to help diagnose and treat it. This damage is called a traumatic brain injury (TBI). Here’s how damage can happen: A sudden movement of the head and brain can cause the brain to bounce or twist in the skull, injuring brain cells, breaking blood vessels, and creating chemical changes. Head injuries can happen to anyone, at any age, and they can damage the brain. These things-and more-can cause head injuries.
