Former NFL running back Chris Johnson has publicly announced his diagnosis of amyotrophic lateral sclerosis (ALS) in a heartfelt interview on Good Morning America. The 40-year-old athlete, known for his impressive career with the Tennessee Titans, shared his journey with the progressive neurodegenerative disorder, which currently has no cure.

Johnson’s diagnosis came in 2025, shortly after he noticed a weakening grip in his right hand. At the time, the former star was leading an active lifestyle, enjoying life with his wife Brittany and their four children. Reflecting on the initial signs, he said, “It started with small things like my grip not feeling strong.” His wife, Brittany, initially believed the symptoms could be related to Johnson’s extensive career in football, perhaps a pinched nerve rather than anything as serious as ALS.
After several rounds of tests, the couple received the devastating news they had feared. “We hoped it was something else, but after the third testing, they finally came down with a diagnosis of ALS,” Chris recalled. The doctors not only advised them to consider the grim prognosis but also suggested a medication that might extend his life by a few months. The harsh reality of the diagnosis weighed heavily on the family.

ALS, often referred to as Lou Gehrig’s disease, leads to the degeneration of nerve cells in the brain and spinal cord, ultimately impacting motor control. Johnson has been diagnosed with sporadic ALS, the most prevalent form of the disease, which occurs in individuals with no known genetic predisposition. Its unpredictable nature can catch those diagnosed completely unaware, making the diagnosis all the more shocking.
Dr. Merritt Cudkowicz, a neurologist at Mass General Brigham Neuroscience Institute, is overseeing Johnson’s treatment. Chris is on a regimen of standard ALS medications while also participating in a clinical trial aimed at reducing inflammation, which has reportedly provided him with some relief. “Chris has been on standardized care, which involves three different medications to slow down the illness,” Dr. Cudkowicz explained.

Despite the treatment, Johnson has experienced a rapid progression of the disease. He is now reliant on a speech-generating device operated by eye movement to communicate. “It’s continued to progress much faster than I ever imagined,” Johnson lamented. He underscored how drastically his abilities have declined over a short span, noting, “Just over a year ago, I was picking up my seven-year-old daughter. Today, I can’t do that.”
In the midst of this challenging journey, Johnson has emphasised that while his physical capabilities have changed, his essence remains the same. “People sometimes look at the physical disability and assume you’re not the same person. My mind stays sharp. I still dream. I still love my family. My body just doesn’t cooperate,” he stated resolutely.
When asked about his decision to go public with his diagnosis, Johnson expressed a desire to use his experience to benefit others. “If sharing my story helps even one person get diagnosed sooner, inspires more research or gives another family hope, then it’s worth it,” he affirmed.
Brittany Johnson shared her own emotional turmoil following the diagnosis, noting her immediate concerns for their children. She admitted to moments of denial, hoping for a misdiagnosis before confronting the drastic change their family would face. “The life that we previously had is now a thing of the past,” she conveyed, although she also expressed hope for a medical breakthrough or divine intervention.
Chris credited his family with providing him the motivation to continue fighting against ALS. “She hasn’t left my side through any of this,” he said of Brittany. “My kids are a huge part of why I keep going. Every day I wake up wanting more time with them.”
Brittany acknowledged the challenges of her new role as Chris’s primary caregiver, describing the emotional and physical toll it takes. “It’s tough. We have good days, we have bad days,” she revealed, highlighting the heavy workload that has come with their new reality. Yet she firmly believes she is meant to be there for her husband during this critical time.
Despite the severity of his condition, Chris Johnson remains hopeful about the future. He believes ongoing research and trials hold potential for all those affected by ALS. “Seeing how hard these doctors and researchers are working gives me hope,” he stated. “As long as they’re fighting for people with ALS, I’m going to keep fighting too.”
