A concussion after a car accident can cause headaches, dizziness, nausea, confusion, memory problems, sensitivity to light, and changes in sleep or mood. Some symptoms appear immediately, while others may develop hours or days after the crash. Because they can be subtle, people sometimes overlook a possible head injury, especially when there are no visible wounds.
If you were in a car accident in Lincoln, Nebraska, understanding the signs of a concussion can help you recognize when to seek medical attention and why documenting your symptoms may matter if you later pursue an injury claim.
Key takeaways
A concussion is a type of mild traumatic brain injury (mTBI) caused by a bump, blow, or jolt that affects how the brain functions. In a car accident, a sudden change in speed or direction can make the head and body move forcefully, so a concussion may occur even when a person doesn’t strike their head on the steering wheel, window, or another object.
The word “mild” describes the medical classification, not how much the injury affects daily life. Many people recover within several weeks, but some have symptoms that last longer and need additional medical attention.
According to the Centers for Disease Control and Prevention (CDC), concussion symptoms differ from person to person and may change during recovery.
Physical symptoms include persistent or recurring headaches, dizziness or trouble with balance, nausea or vomiting, blurred vision or other visual disturbances, increased sensitivity to light or noise, and unusual fatigue. People may first blame stress or exhaustion after a collision, but new symptoms after a crash should be discussed with a healthcare professional.
Cognitive symptoms may include difficulty concentrating, remembering recent events, processing information, or completing familiar tasks. Some people describe feeling mentally foggy, slowed down, or unusually confused, and these changes can interfere with work, school, driving, and daily activities.
Emotional and sleep-related symptoms may include irritability, anxiety, unusual emotional reactions, or mood changes, along with trouble falling asleep, sleeping more than usual, or disrupted sleep patterns. Because these changes may not appear right away, they can be harder to connect to the accident.
Yes. Some concussion symptoms develop hours or days after an injury. A driver or passenger may feel relatively normal at first and later notice headaches, dizziness, trouble concentrating, or increased fatigue. Delayed symptoms don’t automatically establish that a concussion occurred or that the collision caused it, and similar symptoms can result from other injuries or health problems, which is why a medical evaluation matters. If new symptoms develop, explain the timing and circumstances to a healthcare professional.
Certain symptoms may indicate a more serious brain injury. Seek emergency care or call 911 if someone develops:
These warning signs shouldn’t be ignored or delayed while considering an insurance claim. The CDC recommends immediate emergency evaluation when they occur.
Medical care comes first. Steps that may help:
Recovery varies. The CDC recommends contacting a healthcare provider if symptoms don’t improve within two to three weeks or worsen after returning to normal activities.
When someone seeks compensation for injuries allegedly caused by another driver’s negligence, the available evidence may be important. Concussion symptoms can be hard to assess because many aren’t externally visible, so medical records may help explain the symptoms, the treatment, and how the condition affected daily life. Relevant records may include:
An insurer may examine when symptoms were first reported, whether the medical history fits the collision, and whether other conditions could explain the complaints. A diagnosis doesn’t automatically establish another driver’s legal responsibility. Liability, causation, and the extent of damages must be evaluated from the evidence.
Some people leave a crash scene without realizing they may have a head injury. If symptoms appear later, it’s still important to seek evaluation. An insurer may question the time between the collision and the first treatment. That gap doesn’t necessarily mean the symptoms are unrelated, but it may raise questions about when the injury occurred. Accurate records and a clear symptom history can help explain the timeline. Don’t guess at medical causes or change the timing of symptoms to fit a claim; give healthcare professionals an accurate account of what happened.
Nebraska generally provides a four-year statute of limitations for many negligence-based personal injury lawsuits. (Neb. Rev. Stat. § 25-207.) Different deadlines or procedures may apply, including for claims involving governmental entities or other statutory exceptions, so don’t assume every car accident claim fits the general period. The applicable deadline should be evaluated based on your specific case.
Nebraska generally requires a driver to file a crash report with the Nebraska Department of Transportation within 10 days when a reportable collision wasn’t investigated by a peace officer. Injury or death makes a collision reportable, and for crashes on or after July 18, 2026, the property-damage threshold is $2,000. If law enforcement investigates and completes the required report, the driver generally doesn’t need to submit a separate driver’s report. (Neb. Rev. Stat. § 60-699; confirm the current threshold and wording before relying on them.)
A documented concussion may be relevant to evaluating damages. Depending on the facts, relevant losses may include medical expenses, lost income, reduced ability to perform certain activities, and other legally recoverable damages. An insurer may consider the severity of the injury, the medical evidence, the treatment history, the recovery, and whether the collision caused the claimed symptoms. There is no standard settlement amount for a concussion, a diagnosis doesn’t guarantee compensation, and the outcome depends on liability, medical evidence, applicable law, and other circumstances.
Can you have a concussion without hitting your head? Yes. A sudden jolt to the body can make the brain move within the skull and cause a concussion without direct head contact.
Can a concussion occur without losing consciousness? Yes. Loss of consciousness isn’t required. A person can stay awake and still have symptoms of a mild traumatic brain injury.
Can a concussion affect your ability to work? It can. Headaches, fatigue, dizziness, and trouble concentrating may interfere with work, and a healthcare professional can assess whether temporary restrictions or adjustments are appropriate.
What if my concussion symptoms don’t improve? Contact your healthcare provider for reassessment. Persistent or worsening symptoms may need additional evaluation, treatment, or a specialist referral.
Can I still have a concussion if my CT scan or MRI came back normal? Yes. A concussion is generally diagnosed from your symptoms, history, and a clinical exam, and standard imaging often looks normal even when a concussion has occurred. Providers sometimes order a scan to rule out more serious problems, such as bleeding, so a normal result can be good news without meaning you weren’t injured. Keep reporting your symptoms accurately to your provider, and keep the records of any testing and the provider’s findings, since an insurer may ask about them.
