Concussion and post-concussion symptoms after a car accident
Concussion symptoms can be subtle at first and evolve over time. In NSW CTP matters, disputes often arise around evidence quality, alternative explanations, and how functional impact is documented.
General information only — the right pathway depends on your circumstances.
1) Common symptom patterns
- Headaches and dizziness
- Fatigue and sleep disruption
- Brain fog, memory and concentration issues
- Light/noise sensitivity
- Mood changes (anxiety/irritability)
2) Evidence that commonly matters
- Early medical records documenting symptoms and mechanism of injury

Frequently asked questions
- Can concussion symptoms last months?
- Some people experience prolonged symptoms such as headaches, dizziness, fatigue, cognitive issues and sensitivity to light/noise. If symptoms persist, appropriate medical assessment is important.
- What evidence usually matters in concussion-related disputes?
- Early documentation of symptoms, consistent medical history over time, specialist assessments where indicated, and evidence of functional impact (work/study tolerance, driving, daily activities).
- Do I need imaging to prove concussion?
- Not necessarily. Imaging can be normal in concussion. What matters is the clinical history, documented symptoms and functional impact.
