Which of the following is an emotional symptom associated with a concussion?

Heightened emotions are recognized as an emotional symptom associated with a concussion. Following a concussion, individuals often experience a range of emotional disturbances that can manifest as increased sensitivity to emotions, such as irritability, sadness, or anxiety. This heightened emotional state is part of the brain’s response to injury, impacting how a person processes feelings and interacts with their environment.

In contrast, the other choices do not accurately represent typical emotional symptoms following a concussion. Increased energy levels and improved concentration are not common reactions; in fact, individuals often experience fatigue and difficulty focusing. Stable mood fluctuations, while they may occur, do not capture the specific element of increased emotional sensitivity and volatility that is characteristic of a concussion.
