Post-concussion syndrome refers to persistent symptoms such as:

• A. Persistent, on-going symptoms such as problems with attention, memory, fatigue, sleep, headache, dizziness, irritability, or changes in mood and personality
• B. Acute headaches only
• C. No symptoms after concussion
• D. Only dizziness

Answer: (A)

Post-concussion syndrome is about symptoms that persist for an extended time after a concussion, spanning multiple areas of function. It’s not limited to a single problem. People may experience cognitive difficulties like trouble focusing or memory lapses, physical symptoms such as ongoing fatigue, sleep disturbance, headaches, and dizziness, and emotional changes including irritability or mood/personality shifts. Because these signs endure beyond the typical recovery window and can affect several domains, this description best fits post-concussion syndrome. The other options describe only immediate or isolated issues—acute headaches, no symptoms at all afterward, or only dizziness—which don’t capture the broad, lasting symptom pattern characteristic of PCS.
