# Christina Applegate Reveals Multiple Sclerosis Misdiagnosis Actor shares ongoing health struggles after learning her MS diagnosis was incorrect. - **Source:** [Gizmodo](https://gizmodo.com/) - **Published:** 2026-10-20 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/3fcdc5ca-c09b-4f7f-adb5-3f2945fe3850 ## Unexpected Medical Diagnosis Shift Actor Christina Applegate recently announced that she does not have multiple sclerosis, despite living under that diagnosis since August 2021. After experiencing worsening symptoms that necessitated wheelchair use, she returned to her podcast to reveal that doctors have retracted the MS label. She remains without a definitive explanation for her condition. ## The Complexity of MS Diagnosis Multiple sclerosis is an autoimmune condition damaging the myelin sheath, causing numbness and muscle weakness. Because no single definitive test exists, clinicians rely on MRI scans to detect central nervous system lesions. However, these findings can be mimicked by other conditions, leading to significant diagnostic challenges for patients and medical professionals. ## High Rates of Misdiagnosis Research published in 2019 by Dr. Marwa Kaisey highlights that approximately 18% of new patients admitted to specialized clinics were initially misdiagnosed with MS. These patients often begin aggressive therapies intended to slow disease progression before discovering they have alternative conditions. This reveals a systemic issue within current neurological diagnostic protocols. ## Common Alternative Medical Conditions When patients are misdiagnosed with MS, they often suffer from other specific ailments. According to clinical data, the most frequent alternative diagnoses include migraines at 16%, radiologically isolated syndrome at 9%, and both spondylopathy and neuropathy at 7% each. These conditions frequently produce symptoms or MRI findings that overlap with multiple sclerosis. ## Impact on Patient Quality Despite the news that she does not have MS, Applegate reports no improvement in her physical health. She continues to struggle with mobility, requiring a wheelchair for doctor visits. For the actor, the diagnostic shift has not provided a magical solution, leaving her to navigate the same debilitating symptoms without a name. ## Podcast as a Support Platform Applegate co-founded the MeSsy podcast with Jamie-Lynn Sigler in March 2024 to discuss living with chronic diseases. Following a brief hiatus for book launches and her own hospitalization, Applegate returned to share her journey. The platform serves as a space for candid conversations about the realities of managing long-term health issues. ## Global Prevalence of MS Multiple sclerosis remains a significant global health concern, with an estimated one million people diagnosed in the United States alone. Worldwide, approximately 3 million individuals are living with the condition. Scientists continue to investigate potential triggers, including the Epstein-Barr virus, which has been strongly linked to the emergence of the disease. ## Clinical Uncertainty and Future The case of Christina Applegate underscores the limitations of current diagnostic criteria in neurology. As medical professionals continue to search for the source of her symptoms, the situation highlights the necessity for more precise testing methods. Patients facing chronic neurological issues often endure long, uncertain paths before reaching an accurate clinical conclusion. ## Sources covering this story - https://gizmodo.com/christina-applegate-was-misdiagnosed-with-multiple-sclerosis-it-happens-more-often-than-youd-think-2000828184 — --- _Summary written by Brifing from the original reporting.
