Which symptom is NOT associated with concussion?

Euphoria is not a symptom associated with a concussion. Concussions typically result from a blow to the head or a jolt that causes the brain to move rapidly within the skull. This trauma can lead to a variety of symptoms, which often include drowsiness, blurred vision, and dizziness, as the brain struggles to function normally. Drowsiness may occur as a result of altered levels of consciousness or increased fatigue following the injury. Blurred vision is a common visual disturbance following a concussion, as the brain’s ability to process visual information may be compromised. Dizziness can result from balance issues or changes in brain function post-injury.

In contrast, euphoria is generally not characteristic of concussion but rather an elevated mood state that might arise in different psychological conditions or after some forms of intoxication. Therefore, recognizing euphoria as unrelated to concussive symptoms is key in understanding the scope of effects that can be expected following such an injury.
