Which condition is defined as an injury to the head caused by a bump, blow, or jolt that causes the head and brain to move rapidly back and forth?

• A. Clouding of the lens
• B. Inflammation of a joint
• C. A bump, blow, or jolt to the head that causes the head and brain to move rapidly back and forth
• D. A genetic disorder present at birth

Answer: (C)

Concussion is an injury to the head that happens when a bump, blow, or jolt causes the head and brain to move rapidly back and forth inside the skull. That rapid movement can stretch and damage brain cells, leading to symptoms like headache, dizziness, confusion, or even temporary loss of consciousness. The description in the question matches this head-and-brain movement injury, which is distinct from eye problems like clouding of the lens, joint inflammation, or congenital (present at birth) genetic conditions. If someone might have a concussion, it’s important to seek medical evaluation and avoid further injury during recovery.
