A concussion is a type of mild traumatic brain injury (TBI) that happens when a sudden blow, bump, or jolt causes the brain to move inside the skull. Although it is usually not life-threatening, a concussion can have serious short-term and long-term effects if ignored. Understanding its signs, risks, and treatment is essential for protecting brain health.The human brain floats in cerebrospinal fluid inside the skull, which acts like a cushion. When the head experiences a strong impact—such as in a fall, accident, or sports injury—the brain can hit against the skull walls. This disrupts normal brain function, leading to temporary changes in memory, coordination, and thinking ability.
Concussions can happen to anyone, but they are most often linked to: Sports injuries (football, boxing, soccer, cricket, etc.), Road accidents or whiplash, Falls, especially in children and the elderly, Physical assaults or accidental head trauma at home/work.
Concussion symptoms may appear immediately or several hours later. Some common signs include: Persistent headache or pressure in the head, Dizziness, loss of balance, or blurred vision, Confusion or memory problems, Sensitivity to light and sound, Nausea or vomiting.
There is no single medicine to “cure” a concussion—rest is the most important treatment. Doctors usually recommend: Physical rest: Avoid sports, heavy exercise, and activities that risk another head injury. Cognitive rest: Reduce screen time, studying, and intense mental tasks until symptoms improve. Gradual return to activity: Slowly resume normal routines under medical supervision.
