What are the primary symptoms of a concussion?

Confusion, headache, dizziness, and nausea are indeed primary symptoms of a concussion. A concussion is a type of traumatic brain injury that can occur following a blow to the head or a jolt to the body that causes the brain to move rapidly within the skull. This movement can disrupt normal brain function, leading to the symptoms listed.

Confusion is often experienced, as the individual may have difficulty understanding their surroundings or processing information. Headaches frequently accompany concussions due to the strain and injury to brain tissues. Dizziness can occur as a result of the brain’s vestibular function being affected, impacting balance and spatial awareness. Nausea can be triggered by the disturbance in brain function or the result of pain from a headache.

While vision problems and hearing loss can be associated with more severe brain injuries, they are not classified as primary symptoms of concussion. Fatigue may occur in conjunction with a concussion but is not one of the hallmark signs. Increased appetite is not typically associated with concussions and could suggest other issues unrelated to the injury. Memory loss and sensitivity to light or noise are also symptoms of concussions, but they are generally secondary and not as commonly recognized as the symptoms in the first group.
