What Types of Brain Injuries Are Common After a Car Accident?
Car crashes can cause brain injuries ranging from a mild concussion to more serious bleeding or bruising in the brain. In real claims, the key is documenting symptoms and functional change so the medical record matches the crash timeline.
- Concussion (mild TBI): headaches, dizziness, “fog,” sleep or mood changes.
- Contusion: bruised brain tissue that may show on imaging.
- Intracranial bleeding: bleeding around or inside the brain that can be urgent.
- Diffuse injury patterns: symptoms that come from force and rotation, not just a head strike.
MedlinePlus’s traumatic brain injury overview explains that a TBI can happen after a blow, bump, or jolt to the head, which is exactly what a collision can create. CDC’s concussion symptom list includes headaches, dizziness, and trouble thinking clearly, which is why we tell people to track symptoms early and consistently.
Can You Have a Concussion Without Hitting Your Head?
Yes, you can have a concussion even if your head never hits the steering wheel, window, or headrest. A hard jolt can transmit force through the body and still disrupt normal brain function, so “no head strike” is not the end of the analysis.
- Body-force transmission: the crash moves your body and your brain moves inside the skull.
- Airbag and seatbelt dynamics: restraints can stop you fast while your brain keeps moving.
- Delayed symptoms: some people feel worse hours later, not in the first five minutes.
- Proof strategy: tie symptom onset to specific activities and limits, not just pain scores.
Johns Hopkins Medicine’s concussion guide notes that concussion can also result from an injury to another part of the body that transmits force to the head. This is why we ask detailed questions about seatbelt marks, body positioning, and the exact sequence of movement in the crash.
This is why we build the story from objective anchors: photos, timestamps, first calls, and early notes. That is what we mean by leverage when an insurer tries to reduce a brain injury to “just soreness.”
When Should You Go to the ER After a Crash for Head Symptoms?
Go to the ER right away if you have concussion “danger signs,” your symptoms are worsening, or you lost consciousness. If symptoms are mild and stable, get evaluated promptly anyway and follow medical instructions, because early documentation often matters later.
| Go Now / Call 911 | Get Checked Soon |
|---|---|
| Worsening headache, repeated vomiting, seizure, weakness, or confusion. | Persistent headache, dizziness, fogginess, sleep changes, or mood shifts. |
| Slurred speech, unequal pupils, cannot stay awake, or unusual behavior. | Symptoms that show up hours later, especially after exertion or screen time. |
CDC’s listed concussion danger signs include worsening headache, repeated vomiting, seizures, and increasing confusion. If you are unsure, choose safety and get medical care, then keep copies of discharge papers and follow-up instructions.
Timeline Builder: The First 72 Hours After a Suspected TBI
The first 72 hours are about two things: protecting your health and preserving clean evidence before it changes. A simple timeline can prevent later disputes about when symptoms started and how they affected daily function.
Use this 5-step sequence:
- Build a timeline: crash time, first symptoms, first care, and first missed activity.
- Link symptoms to function: write what changed at work, home, driving, sleep, and screen time.
- Stay consistent: follow-ups, restrictions, and medication notes should match what you report.
- Use the right tests when needed: balance, cognitive screening, and referrals if symptoms persist.
- Preserve non-medical evidence: vehicle photos, cabin photos, witness names, and key timestamps.
This is why we encourage people to preserve crash data before vehicles are repaired or moved. NHTSA’s event data recorder overview explains that some vehicles record information related to a crash “event,” which can become important when impact severity is disputed.
What Medical Records and Testing Help Prove a TBI?
The best medical record is consistent: it documents symptoms, shows functional limits, and reflects follow-up care. Imaging can help rule out emergencies, but many concussions do not show up on routine CT or MRI.
| Record or Test | Why It Helps |
|---|---|
| ER note and discharge instructions | Shows the first documented symptom set and the initial medical timeline. |
| Primary care or specialist follow-ups | Reduces “gap in care” arguments and tracks persistence or change over time. |
| Symptom and function log | Connects dizziness, headaches, or fog to work, driving, sleep, and daily tasks. |
| CT or MRI when ordered | Helps rule out bleeding or other urgent complications after head trauma. |
| Cognitive and balance screening | Provides structured measurements when symptoms affect attention, memory, or coordination. |
Cleveland Clinic’s concussion guide explains that imaging tests cannot diagnose a concussion, but providers may order CT or MRI to look for serious complications like bleeding. CDC’s Acute Concussion Evaluation tool notes that concussion is typically associated with normal structural imaging findings, which is why symptom documentation and functional detail matter so much.
If your symptoms persist, ask your clinician about structured assessment options. Johns Hopkins Medicine describes neuropsychological testing as one way to detect problems with memory and other brain functions.
Defense Audit: Common TBI Narratives and Evidence Anchors
Insurance defenses in TBI cases tend to repeat, and you can plan for them without exaggerating anything. The goal is to match each narrative with a simple evidence anchor so the record answers the question before it hardens into a dispute.
| Common Defense Angle | Evidence Anchor That Helps |
|---|---|
| “Low impact means no brain injury.” | Photo set, repair records, and any available crash data; consistent symptom onset and function log. |
| “No head strike, so no concussion.” | Same-day symptom report, exam findings, and a clear description of body-force and motion. |
| “CT/MRI is normal, so you are fine.” | Ongoing symptom documentation and follow-ups that show real-world limits over time. |
| “This is pre-existing.” | Prior baseline records plus documented new changes after the crash date. |
| “You’re fine now.” | Work notes, activity limits, missed time documentation, and follow-up plan compliance. |
That is what we mean by leverage: we build a record that makes the debate about facts, not vibes. If you want a focused plan for building a brain injury claim record, start with timeline and symptom-to-function notes and keep everything organized by date.
What We See in Practice
In most car accident brain injury cases, the fight is usually about proof gaps, not whether the crash happened. We see insurers lean hard on delay, inconsistency, and “normal imaging” to reduce what the injured person reports.
- Gaps in care: missed follow-ups become “you must be fine” talking points.
- Thin notes: charts that say “headache” without function detail leave room to argue severity.
- Early recorded statements: quick questions can lock in an incomplete symptom picture.
- Low-impact framing: property damage becomes a substitute for medical analysis.
We also see people push through work, school, and screen time because they feel pressure to “be normal,” and then they crash later when symptoms spike. A daily symptom-to-function log keeps you honest and makes your record clearer without forcing you to guess.
This is why we focus on dates, consistency, and third-party documentation like work notes, appointment summaries, and repair records. When the documentation matches the timeline, the claim becomes harder to dismiss.
What Should You Do Next After a Suspected Brain Injury?
Next steps should protect both your health and your claim without turning your life into a paperwork project. Focus on consistent care, clean documentation, and preserving the items that can disappear.
- Get evaluated: follow medical guidance and ask what symptoms to monitor.
- Write it down: keep a dated symptom-to-function log that stays consistent.
- Preserve the crash proof: photos, repair estimates, tow records, and witness contact info.
- Be cautious with insurers: do not let “small talk” become a permanent record of missing symptoms.
- Get guidance if the story is being disputed: low-impact and “normal imaging” arguments are common.

Louisiana Law Snapshot (Updated 2026)
Louisiana deadlines and fault rules can shape a brain injury case as much as the medicine does. Start with the filing deadline and comparative fault, then confirm any special rules that apply to your facts.
| Rule | What It Means in Plain English |
|---|---|
| Two-year prescription | La. Civ. Code art. 3493.1 sets a two-year prescriptive period for most delictual actions, and the clock generally starts when injury or damage is sustained. |
| Comparative fault and the 51% bar | La. Civ. Code art. 2323 reduces damages by your share of fault, and the updated rule generally bars recovery when a claimant is 51% or more at fault for accidents on or after Jan. 1, 2026. |
Deadlines do not pause just because an insurer is “still investigating,” so treat the calendar as separate from settlement talks. This is why we triage evidence and deadline issues early, even while medical care is still developing.
