Yes, you may be able to sue for a brain injury diagnosed days after an accident. Some brain injuries, including concussions and other traumatic brain injuries, may not cause obvious symptoms immediately, so a delayed diagnosis does not automatically prevent you from pursuing compensation. The strength of your claim will depend on the available evidence, the circumstances of the accident, and the applicable law.
Delayed symptoms can make it harder to establish a connection between an accident and a brain injury. However, traumatic brain injuries may cause symptoms such as headaches, dizziness, confusion, memory problems, or sensitivity to light that become noticeable hours or days later. Seeking medical attention promptly after symptoms appear can help document the injury and support your claim.
Why Brain Injuries May Be Diagnosed Later
Brain injuries are not always immediately apparent after a car crash, fall, workplace incident, or other accident. Adrenaline, shock, and initially mild symptoms may cause someone to overlook signs that require medical evaluation.
As symptoms develop, a doctor may recommend neurological examinations, imaging tests, or other assessments to determine the cause. Medical records documenting when symptoms began and how they progressed can help explain why the injury was diagnosed after the accident.
What Evidence Can Support Your Claim
To pursue compensation, you generally need evidence showing that another party’s negligence or wrongful conduct caused the accident and your injury. Useful evidence may include medical records, diagnostic results, accident reports, photographs, witness statements, and surveillance footage.
Keep records of all medical appointments, treatment recommendations, prescriptions, and expenses. If the injury affects your ability to work or perform daily activities, employment records and documentation of those limitations may also help demonstrate your losses.
How Negligence Laws May Affect Your Case
The legal requirements for a brain injury claim depend on the state where the accident occurred and the circumstances involved. For example, California Civil Code § 1714 generally establishes responsibility for injuries caused by a person’s lack of ordinary care, which may be relevant when a brain injury results from another party’s negligence.
You must also consider the deadline for filing a lawsuit. In California, Code of Civil Procedure § 335.1 generally provides a two-year limitation period for actions seeking damages for injury or death caused by another person’s wrongful act or neglect. Exceptions may apply, and the date of diagnosis does not automatically determine when the filing deadline begins.
What to Do After a Delayed Diagnosis
Seek medical care as soon as possible if you develop possible brain injury symptoms after an accident, even if you initially felt fine. Follow your healthcare provider’s instructions and explain when the accident occurred and when each symptom began.
Preserve relevant evidence and consider speaking with a personal injury attorney about your options. If symptoms include worsening headaches, repeated vomiting, seizures, increasing confusion, weakness, or difficulty staying awake, seek emergency medical care immediately.
