A teenage football player had months of symptoms after a concussion. Doctors found a rare brain malformation.

Logan Coleridge, a New Jersey teen and football player, experienced debilitating symptoms after a helmet-to-helmet impact in August 2023, leading to a diagnosis of an arteriovenous malformation (AVM) after multiple failed treatments and a delayed MRI. He underwent surgery on July 17, 2024, to remove the AVM, which was likely the cause of his persistent headaches and cognitive issues.
