Concussione

Concussione, commonly known in English as a concussion, is a mild traumatic brain injury that occurs when the brain briefly moves inside the skull, often due to a blow, fall, or sudden jolt to the head or body. The impact disrupts normal brain function and can produce a range of neurological symptoms that may appear immediately or develop over several hours.

Typical signs include headache, confusion, dizziness, nausea, balance problems, and temporary loss of memory. Affected individuals may also experience sensitivity to light or sound, blurred vision, and emotional changes such as irritability or anxiety. While most people recover fully, the severity and duration of symptoms vary, and repeated concussions can increase the risk of long‑term neurological conditions.

Diagnosis relies on clinical assessment by trained professionals, using standardized tools such as the Glasgow Coma Scale, the Sport Concussion Assessment Tool, and neuroimaging when indicated. Imaging like CT or MRI may rule out more severe injuries; however, concussions rarely show structural changes on these scans, so history and symptom evaluation are critical.

Treatment focuses on rest, both physical and cognitive, followed by a gradual reintroduction of activities once symptoms abate. Early aerobic exercise has been shown to speed recovery, while complete avoidance of high‑impact sports is recommended until clearance. Medications may be prescribed for pain or to manage mood disturbances but are not a primary treatment for the concussion itself.

Prevention emphasizes head protection through helmets in contact sports, using seat belts, wearing lifeguard-approved safety equipment, and maintaining safe environments to reduce falls or rapid impacts. Educational programs for athletes, coaches, and the public are essential to promote awareness of concussion risks and early medical evaluation.
