Christina Applegate reveals 2021 MS diagnosis was wrong, but symptoms persist
Christina Applegate disclosed on October 20 that her 2021 multiple sclerosis diagnosis was incorrect. Despite the correction, her debilitating symptoms remain unchanged and have potentially worsened. Doctors are now investigating the true cause of her condition, leaving her without a definitive medical explanation.
Key points
- Applegate revealed the misdiagnosis on her 'MeSsy' podcast on October 20, 2026.
- She stated her symptoms, including intense pain and mobility issues, have not improved and may have worsened.
- Applegate described feeling 'back at square one' and confused about the cause of her ongoing health struggles.
- Her doctors are currently investigating to determine the actual condition causing her symptoms.
- Applegate expressed concern about disappointing the MS community after years of advocacy.
Background
Applegate first revealed her MS diagnosis in 2021, subsequently writing a memoir and hosting a podcast to raise awareness. She has been open about her struggles with depression, pain, and mobility, including a lengthy hospital stay earlier in 2026. The misdiagnosis revelation comes five years after her initial public disclosure.
How outlets are covering it
All four sources (Los Angeles Times, Washington Post, CNN, Fox News) report the core facts: the misdiagnosis, the persistence of symptoms, and Applegate's emotional reaction. The Washington Post and Fox News include input from Dr. Marwa Kaisey, a neurologist at Cedars-Sinai, who noted that MS misdiagnoses are common due to the lack of a single definitive test. Fox News emphasized Applegate's emotional distress and her sense of having 'let everybody down,' while the Los Angeles Times focused on her statement that she is 'back at square one.' CNN highlighted her role as a leading MS advocate. There is no disagreement on the facts, but the emphasis varies between the emotional impact (Fox), the medical context (Washington Post), and the advocacy implications (CNN/Los Angeles Times).
Why it matters
The misdiagnosis of a high-profile advocate highlights the challenges in diagnosing MS, a condition with no single definitive test. It also raises questions about the impact of incorrect diagnoses on patients and their advocacy efforts. Applegate's ongoing symptoms, despite the corrected diagnosis, underscore the complexity of her health condition and the need for further medical investigation.
What to watch
Applegate's doctors are currently investigating the root cause of her symptoms. She is expected to continue her advocacy work, though the misdiagnosis may impact her relationship with the MS community. Further updates on her health and the results of her medical investigation are anticipated.
