Early Warnings of Multiple Sclerosis: Signs That Can Forecast the Disease Up to 15 Years Ahead
In a groundbreaking study published in 2025, researchers from the University of British Columbia have unveiled early warning signs of Multiple Sclerosis (MS), a neurological disease that affects nearly 3 million people worldwide. The study, which analyzed patient clinical histories for 25 years, found that the early signs of MS can appear up to 15 years before the typical onset of classical neurological symptoms [1][2][3].
Key early symptoms identified include:
- Fatigue
- Headache and migraine
- Pain, including musculoskeletal pain
- Mental health concerns, such as anxiety and depression
- Dizziness and balance issues (vertigo)
- Visual disturbances, which typically emerge around 8–9 years before diagnosis
- Increased healthcare usage, including visits to general practitioners, neurologists, ophthalmologists, emergency rooms, and radiologists, which escalates notably as symptom onset approaches [1][2][4][5]
The trajectory of symptoms shows an evolution:
- Around 15 years prior to diagnosis, patients present with vague, ill-defined symptoms that are often non-specific and easily mistaken for other conditions (e.g., fatigue, headaches, mental health issues) [1][4][5].
- Between 8 to 9 years before diagnosis, more MS-related symptoms such as visual disturbances and neurological complaints emerge, reflected by increased visits to specialists like neurologists and ophthalmologists [4][5].
- In the few years immediately preceding diagnosis, there is a surge in symptoms directly related to MS, including sensory changes, musculoskeletal pain, and neurological signs, alongside more intense healthcare engagement [5].
This research significantly shifts the understanding of the MS prodrome (early disease phase) duration and symptoms, indicating MS’s pathological process starts long before classical signs like numbness or weakness appear. Early recognition of these nonspecific symptoms may facilitate earlier diagnosis and intervention, potentially improving patient outcomes [1][4].
The authors of the study emphasize the need for early intervention to help speed up diagnosis rates and treatment management. They urge healthcare professionals to be vigilant for these early warning signs and to consider MS as a possible diagnosis in patients presenting with these symptoms, even if they do not yet meet the full criteria for a MS diagnosis.
In summary, early signs of MS can appear more than a decade before diagnosis, starting with general symptoms such as fatigue and mental health changes and progressing to more specific neurological and visual symptoms closer to the onset of classical MS symptoms [1][4][5]. By recognizing and addressing these early signs, healthcare professionals may be able to help patients manage their symptoms more effectively and potentially slow the progression of the disease.

- Someone might ask, "What are some subtle signs of Multiple Sclerosis (MS) that could be overlooked by healthcare professionals and patients alike?"
- The study on the prolonged early stages of MS highlights the importance of paying attention to health-and-wellness issues such as mental health concerns and fatigue, which could be indicative of medical-conditions like MS.
- For individuals with multiple-sclerosis or those at risk, seeking the help of healthcare professionals as soon as possible upon noticing symptoms like pain, headaches, anxiety, depression, dizziness, balance issues, visual disturbances, or increased healthcare usage may lead to early intervention and improved mental-health and health-and-wellness outcomes.
