After a crash, someone has nightmares, headaches, poor concentration, and gaps in memory. Those symptoms deserve attention, but a checklist cannot determine whether the person has post-traumatic stress disorder, a traumatic brain injury, both, or another condition. The useful starting point is a clinical evaluation supported by an accurate account of the event and what changed afterward.
Different conditions can produce overlapping complaints
The National Institute of Mental Health describes PTSD symptoms involving re-experiencing, avoidance, arousal and reactivity, and changes in cognition or mood. Diagnosis considers the required pattern, symptoms lasting more than a month, and interference with daily life, among other criteria. Distress in the first days after a crash should not automatically be labeled PTSD, but a person does not need to wait a month to seek help.
The CDC’s concussion guidance includes physical, thinking, emotional, and sleep symptoms. Trouble concentrating or sleeping appears in descriptions of both conditions. Having a headache alongside nightmares does not let a patient, insurer, or lawyer assign each complaint to a particular diagnosis.
The VA National Center for PTSD explains the overlap and notes that PTSD can occur even without a clear memory of the event that caused a TBI. It also cautions that neuropsychological test results may not distinguish the conditions because PTSD and sleep difficulties can affect cognitive performance. Clinical interviews and the timing and pattern of symptoms help guide the assessment.
Build one chronology that preserves the uncertainty
Begin with the crash, the earliest reliable observations, and the first medical visit. Then add later symptoms and evaluations. Distinguish the date a problem began from the date it was first reported. If the onset is uncertain, keep that uncertainty visible instead of choosing a date to make the account appear complete.

| Part of the history | Useful records | Question the record can help address |
|---|---|---|
| Immediate condition | Emergency notes, responder observations, witness accounts | What was observed or reported soon after the crash? |
| Later symptoms | Dated messages, appointment notes, a brief symptom log | When did the person notice the difficulty, and what was happening then? |
| Clinical assessment | Complete evaluations, test reports, referrals, and diagnostic explanations | What did the clinician conclude, and what remains under consideration? |
| Earlier history and other changes | Relevant prior records, medication history, sleep history, later events | What baseline or alternative explanation did the clinician consider? |
| Practical effects | Work restrictions, missed shifts, school adjustments, dated observations | Which activities changed, for how long, and with what support? |
For example, “I stopped driving because passing trucks reminded me of the crash” provides different information from “I stopped driving because turning my head made me dizzy.” Preserve the person’s actual explanation, including occasions when both occurred. Neither sentence supplies a diagnosis by itself.
Keep observations separate from medical conclusions
A family member may accurately describe repeated questions or disturbed sleep without knowing their cause. A patient can report difficulty remembering a conversation without deciding that it proves permanent brain damage. Identify who observed each change and what they directly saw.
Keep complete reports and the clinician’s interpretation. A screening score copied into an insurance form may omit qualifications in the assessment. If two providers disagree, preserve both opinions and the records each considered. Ask for clarification through the treating team rather than rewriting the history to remove the disagreement.
The articles on PTSD symptom groups after a crash and documenting accident-related stress discuss additional mental-health context.
Get help while the assessment continues
Seek emergency care for a worsening headache, repeated vomiting, seizure, weakness, slurred speech, increasing confusion, unequal pupils, or difficulty waking after a head injury. These are among the CDC’s danger signs. For a mental-health crisis or thoughts of suicide, call or text 988; call 911 for immediate life-threatening danger, as NIMH advises.
Treatment decisions belong with qualified clinicians. Keep referrals, recommendations, and records of how care affects function. Improvement is part of an accurate record, even when other symptoms remain.
Document the loss without duplicating it
If both conditions contributed to the same missed shift, record that shift once. Identify the dates, hours, pay records, and restrictions supporting the loss. Future counseling, rehabilitation, and medical follow-up should each have a stated clinical basis and expected duration.
