Gabapentin lawsuits are now being filed over dementia, mild cognitive impairment, memory loss, and other serious cognitive problems. New research has raised concerns about a link between these injuries and long-term or repeated gabapentin use.

These cases are still developing, and we are in the early rounds of this. The deeper our lawyers dig into these cases, the more we believe in them.

Now, the litigation is starting to move forward. It seems the center of the litigation will be in state court in Philadelphia. A mass tort program for lawsuits involving gabapentin, sold as Neurontin, and pregabalin, sold as Lyrica, has been established there.

Our lawyers stopped accepting new Tylenol autism and ADHD cases after Judge Denise Cote excluded the plaintiffs’ causation experts, a ruling that led to the dismissal of the federal lawsuits.

There is now real reason for renewed optimism. In July 2026, the Second Circuit overturned the judgments resulting from Judge Cote’s expert testimony rulings. The defendants then asked the appeals court to reconsider, and, as we discuss below, that request has now been denied.

But our firm has not yet resumed accepting new Tylenol autism or ADHD claims. The appeals court did not decide that Tylenol causes autism or ADHD, and important questions about the expert evidence still have to be addressed on remand. We will continue following the litigation and reassess our position as the next steps become clearer.
