Can a Car Accident Cause Chronic Traumatic Encephalopathy (CTE)?
The question matters because concussion, traumatic brain injury, and CTE are not interchangeable terms. A person may have a serious crash-related brain injury without having CTE, and an online article cannot identify the cause of neurological, cognitive, mood, or behavioral changes.
If a collision involved a head impact, loss of consciousness, confusion, memory problems, worsening symptoms, or another immediate concern, seek appropriate medical care. Call emergency services for an emergency.
Can one car accident cause CTE?
The Centers for Disease Control and Prevention says research associates CTE with long-term exposure to repeated hits to the head. The agency also says there is no strong evidence that one or more concussions, other mild traumatic brain injuries, or occasional head impacts lead to CTE.
That evidence does not mean a single crash is harmless. A collision can cause a concussion or a more severe traumatic brain injury. It means that CTE should not be used as a substitute label for every post-crash symptom or brain injury.
CTE and traumatic brain injury are different
A traumatic brain injury is an injury that affects how the brain works. The severity, symptoms, treatment, and recovery vary. CTE is a specific brain disease associated with abnormal protein changes and a history that may involve repeated head impacts over time.
The CDC notes that scientists are not certain which symptoms are directly linked to CTE. Problems with thinking, emotions, mood, or behavior can have many possible causes. A licensed medical professional should evaluate the actual symptoms and history rather than starting with a self-diagnosis.
Rensch & Rensch maintains a separate guide to traumatic brain injury claims after motor vehicle accidents. That legal information does not replace clinical care.
How is CTE diagnosed?
According to the CDC, doctors currently can confirm CTE only by examining brain tissue after death. Research is continuing into methods that may help evaluate the disease in living people, but symptoms alone do not confirm CTE.
A clinician can still evaluate and treat current symptoms. The appropriate examination, testing, referrals, and diagnosis depend on the individual. Tell the treating professional about the crash, all known head impacts, the timing of symptoms, prior medical history, and any changes in daily function.
Records after a crash-related head injury
Accurate records help medical professionals understand what changed and help an attorney evaluate a claim without overstating the evidence. Useful records may include:
- The police report, photographs, and witness information
- Emergency, hospital, primary-care, and specialist records
- Imaging and test reports interpreted by the treating professionals
- A dated account of symptoms, work restrictions, and activity changes
- Prior head-injury, neurological, and mental-health history relevant to the evaluation
- Insurance correspondence and requests for statements or authorizations
Preserve original records and describe symptoms truthfully. Do not change the timing, severity, or history to fit a particular diagnosis. Medical causation and legal causation require evidence specific to the person and collision.
What can a Nebraska injury claim address?
A claim may focus on a diagnosed crash-related injury and its documented consequences, including medical care, income loss, functional limits, and other legally recognized damages. It is not necessary or appropriate to call every brain injury CTE.
Insurers may dispute whether the collision caused a condition, whether another event contributed, or whether a prior condition explains part of the symptoms. Medical records, crash evidence, a reliable timeline, expert opinions when appropriate, and accurate prior history may all matter.
For case-specific advice, review the evidence with a Nebraska attorney. Rensch & Rensch explains its current services on the Omaha catastrophic injury lawyer page and offers free consultations at 402-498-4400.
