Pre-Existing Conditions and Work Brain Injuries: Can You Still Get Compensated?

"You Had This Before" — The Insurer's Favorite Defense

If you have any history of a prior concussion, migraines, anxiety, or an old head injury, expect the insurer to seize on it. Blaming your symptoms on a pre-existing condition is one of the most common ways carriers try to deny brain-injury claims. But Pennsylvania law does not let an employer off the hook just because you weren't in perfect health before. If work aggravated your condition, that aggravation is a compensable injury.

The Key Principle: Aggravation Is a New Injury

Pennsylvania follows a well-established rule: an employer takes the worker as it finds them. You don't have to be a blank slate. If a work incident:

• Aggravated a pre-existing condition,
• Accelerated its progression, or
• Combined with it to cause disability,

then the work-related aggravation itself is a compensable injury, even though the underlying condition predated your job.

How This Plays Out With Brain Injuries

Brain injuries are especially prone to the "pre-existing" attack because:

• Many people have had a prior concussion (sports, a car accident, a fall).
• Symptoms like headaches, memory issues, and mood changes overlap with common conditions.
• Imaging can be normal even with a real injury, letting insurers claim "nothing changed."

The insurer will argue your problems are "just the old condition." Your job—and your lawyer's—is to show the change: how you were functioning before versus after the work incident.

Evidence That Wins These Cases

• Before-and-after testimony—coworkers, family, and you describing your functioning.
• Medical records showing new or worsened symptoms after the work event.
• Treating physician opinions connecting the aggravation to work.
• Neuropsychological testing documenting current deficits.

What Not to Do

• Don't hide your history. Undisclosed prior conditions, once discovered, hurt your credibility. Honesty—paired with the aggravation argument—is stronger.
• Don't accept a denial just because the insurer waved the words "pre-existing."
