Eric Dane, known for portraying Mark Sloan in Grey’s Anatomy, was spotted in a motorized wheelchair at Washington, D.C.’s airport on October 2, 2025, due to advancing amyotrophic lateral sclerosis (ALS). Diagnosed in April, the 52-year-old actor faces progressive mobility loss and is engaging with organizations to accelerate research for the disease, which affects about 30,000 people in the U.S. and has no known cure. Treatments like edaravone aim to slow symptom progression. Dane’s wife, Rebecca Gayheart, and daughters, Billie, 15, and Georgia, 13, have adapted their Los Angeles home to support his daily needs.
Wheelchair use began in July due to reduced mobility.
Home modifications include ramps and assistive devices.
Dane focuses on attending key family milestones, like graduations.
Washington meeting boosts awareness
In September, Dane met with I Am ALS and Congressman Eric Swalwell to discuss the ALS Accelerated Access to Therapies Act, set to expire in 2026. The legislation speeds up clinical trial approvals for new treatments.
He stressed the need for federal funding to advance research and early diagnosis.
