After dedicating five years to advocating for those with multiple sclerosis (MS), Christina Applegate recently disclosed that medical professionals now believe she received an incorrect diagnosis.
Expressing her feelings on the matter, Applegate stated, “It feels like I’m starting over from scratch.” She shared this revelation during a two-part episode of the podcast “MeSsy,” co-hosted with Jamie-Lynn Sigler, who also has MS. Applegate had taken a break from the show to process this new information.
During the podcast, Applegate emotionally recounted that although her doctor had informed her that she did not have MS, she did not feel relief but rather a sense of confusion. She mentioned that her condition had not improved and, if anything, had worsened, particularly affecting her mobility.
Multiple sclerosis is a challenging autoimmune disease that impacts the central nervous system. The immune system mistakenly attacks the myelin, a protective coating for nerves, leading to communication issues between the brain and body, resulting in symptoms like numbness, fatigue, memory problems, mobility impairments, and sometimes vision loss.
Dr. Mark Freedman, the director of the multiple sclerosis research unit at The Ottawa Hospital, likened the disease to a wire losing its outer rubber layer, making the nerve susceptible to inflammation and damage, ultimately disrupting connections permanently.
Misdiagnosis is a global issue, with studies indicating rates ranging from five to 41 percent. Applegate had initially shared her MS diagnosis in 2021, following symptoms like numbness and pain, leading to numerous tests such as MRIs and a spinal tap before receiving the MS diagnosis after the discovery of brain lesions.
In a turn of events, Applegate’s treatment was paused to reassess her condition, leading to the realization that she did not have MS. The absence of a new diagnosis left Applegate feeling lost and uncertain about the cause of her ongoing symptoms.
Despite the setback, Applegate expressed her disappointment at feeling like she let down those who looked up to her as an advocate for MS awareness. She and Sigler had started their podcast in 2024 to discuss their experiences with parenting and everyday challenges while living with the disease.
The article further discusses global MS statistics, the challenges of diagnosing MS due to overlapping symptoms with other conditions, and the risks of treating patients for MS incorrectly. In Canada, the misdiagnosis rate for MS is lower compared to the U.S., attributed to a higher number of MS specialists and dedicated MS centers.
Sigler comforted Applegate during the podcast, reminding her that her advocacy work remains significant, even in light of the misdiagnosis. This incident offers hope that one day, Applegate may find relief and be able to resume activities she once enjoyed, like dancing.
