A concussion is a traumatic brain injury caused by a blow or jolt to the head that disrupts normal brain function. Common symptoms include headaches, dizziness, memory problems, sensitivity to light and sound, and difficulty concentrating. Because symptoms can be delayed and untreated concussions may lead to long-term complications, it's important to seek medical attention right away — even if you feel fine at first.

Most concussions result from a sudden impact caused by someone else's negligence. The leading causes we see include car, truck, and motorcycle accidents; bicycle and pedestrian collisions; slip and fall incidents; sports and recreational activities; and workplace accidents. Identifying the at-fault party is central to your claim, and our attorneys handle that investigation for you.

Concussion victims in California can generally recover both economic and non-economic damages. These commonly include medical expenses and rehabilitation, lost wages and future income, pain and suffering, and the cost of long-term care needs. Because every head injury is different, a legal professional can review your losses during a free case review.

In most California concussion and brain injury cases you have two years from the date of the injury to file a personal injury lawsuit (California Code of Civil Procedure §335.1). Claims against a government entity have much shorter deadlines — often just six months to file a claim. Because missing a deadline can end your case, it's best to speak with a legal professional early.

How Do I Know If I Have a Concussion Injury Claim in California?

Three factors determine whether you have a valid concussion injury claim — fault, damages, and proof. Fault means another party's negligence caused your head injury. Damages are your losses, such as medical bills, lost wages, and long-term care. Proof includes medical records, imaging, incident reports, and witness statements. California's statute of limitations applies, so contact Wilshire Law Firm's attorneys for a free case evaluation.

Brain Injury FAQs

Our Most Frequently Asked Questions

We've answered the most common ones below. If yours isn't here, call us — we're available 24/7.

Yes. A concussion is a mild traumatic brain injury caused by a blow or jolt that disrupts normal brain function. "Mild" describes the initial diagnosis, not the potential impact — concussions can cause lasting headaches, cognitive difficulty, and mood changes.

Delayed symptoms are common with concussions — dizziness, memory problems, sensitivity to light, and difficulty concentrating can surface hours or days later. Prompt medical evaluation protects your health and helps document that the concussion came from the incident.

Concussions often do not show up on standard CT or MRI scans, so proof usually relies on documented symptoms, neurological and cognitive testing, treating-provider records, and accounts from family or coworkers about changes in function. Consistent medical follow-up strengthens this evidence.

Generally two years from the date of injury under California Code of Civil Procedure § 335.1, though the deadline can run from when the injury is discovered. If a government entity is involved, a written claim is usually due within six months first — deadlines have exceptions, so confirm yours promptly.
