Concussion is a traumatic brain injury that can cause lasting effects on brain tissue and change the chemical balance of the brain. Concussion may cause physical, cognitive, and behavioral symptoms and problems, both short-term and long-term. Every concussion is considered a serious injury by health care providers. If you have experienced a head injury, seek medical help immediately.
The Centers for Disease Control (CDC) estimates that 1.6 million to 3.8 million people experience concussions during sports and recreational activities annually in the United States. These numbers may be underestimated, as many cases are likely never reported. A physical therapist can assess symptoms to determine if a concussion is present, and treat the injury by guiding the patient through a safe and individualized recovery program.
What Is Concussion?
Concussion is a brain injury that occurs when the brain is violently shaken. The injury can happen during rapid movement changes (such as whiplash) or when the head is directly hit. This shaking or hitting of the head causes unpredictable injury to any area of the brain, resulting in immediate or delayed changes in the brain's chemistry and function. Less than 10% of concussions involve a loss of consciousness. Depending on which area of the brain suffers injury, many different temporary or permanent problems with brain function can occur.
