Which of the following is NOT a symptom of a concussion?

Loss of taste is not typically recognized as a symptom of a concussion. Concussions primarily affect cognitive functioning, balance, and coordination, leading to common symptoms such as headaches, dizziness, and nausea. Headaches are one of the most frequently reported symptoms after a concussion due to the brain’s response to injury. Dizziness can occur as a result of balance issues or disturbances in the vestibular system, which may be impacted by a concussion. Nausea often accompanies concussive symptoms as well, particularly when combined with headaches and changes in balance.

On the other hand, loss of taste is associated more commonly with other medical conditions, such as upper respiratory infections or neurological issues unrelated to concussions. It is not classified among the immediate effects of a concussion, thereby validating it as the correct answer to the question.
