Key Questions Answered<\/p>\n
Q: How early can signs of multiple sclerosis appear?
A: The study found increased healthcare usage related to MS symptoms up to 15 years before official diagnosis.<\/p>\n
Q: What early symptoms did people with MS report?
A: General symptoms like fatigue, pain, dizziness, anxiety, and depression appeared years before neurological symptoms.<\/p>\n
Q: Why is this research important?
A: It challenges traditional MS diagnostic timelines and opens the door to earlier detection and intervention strategies.<\/p>\n
Summary: A large-scale analysis of health records reveals that subtle signs of multiple sclerosis (MS) may appear more than a decade before diagnosis. People who eventually develop MS began increasing healthcare visits\u2014especially for general symptoms like fatigue, pain, and anxiety\u201415 years before neurologists identified their first demyelinating event.<\/p>\n
These findings suggest a lengthy prodromal phase for MS, similar to early-stage Parkinson\u2019s disease, where nonspecific symptoms quietly precede more recognizable ones. Identifying this earlier timeline could lead to proactive support, monitoring, and even future prevention strategies.<\/p>\n
Key Facts<\/p>\n
Long Prodrome: Healthcare usage increased steadily over 15 years before MS diagnosis.Early Indicators: Fatigue, dizziness, mental health issues, and eye problems were among the first signs.Clinical Shift: Results challenge the belief that MS only begins with clear neurological symptoms.<\/p>\n

The earliest warning signs of multiple sclerosis (MS) may emerge more than a decade before the first classical neurological symptoms occur, according to new research from the University of British Columbia.<\/p>\n
Published today in\u00a0JAMA Network Open, the study analyzed the health records of more than 12,000 people in British Columbia and found that those with MS began using healthcare services at elevated rates 15 years before their first MS symptoms appear.<\/p>\n
The findings challenge long-held assumptions about when the disease truly begins, offering the most comprehensive picture to date of how patients engage with a range of healthcare providers in the years leading up to a diagnosis as they search for answers to ill-defined medical challenges.<\/p>\n
\u201cMS can be difficult to recognize as many of the earliest signs\u2014like fatigue, headache, pain and mental health concerns\u2014can be quite general and easily mistaken for other conditions,\u201d said senior author Dr. Helen Tremlett, professor of neurology at UBC\u2019s faculty of medicine and investigator at the Djavad Mowafaghian Centre for Brain Health.<\/p>\n
\u201cOur findings dramatically shift the timeline for when these early warning signs are thought to begin, potentially opening the door to opportunities for earlier detection and intervention.\u201d<\/p>\n
The study used linked clinical and administrative provincial health data to track physician visits in the 25 years leading up to the onset of a patient\u2019s MS symptoms, as determined by a neurologist through detailed medical history and clinical assessments.<\/p>\n
It is the first study to examine healthcare usage this far back in a patient\u2019s clinical history. Most previous studies only examined trends in the five to 10 years leading up to a patient\u2019s first demyelinating event (such as vision problems) using administrative data. This is a much later benchmark compared to the neurologist-determined date of symptom onset.<\/p>\n
The findings revealed that, when compared to the general population, people with MS had a steady build-up of healthcare engagement over 15 years with different types of doctor visits increasing at distinct points in time:<\/p>\n
\u2022\u00a015 years before symptom onset:\u00a0Visits to general practice physicians increased, as did visits to any physician for symptoms like fatigue, pain, dizziness and mental health conditions including anxiety and depression.
\u2022\u00a012 years before:\u00a0Visits to a psychiatrist increased.
\u2022\u00a0Eight to nine years before:\u00a0Visits to neurologists and ophthalmologists increased, which could relate to issues like blurry vision or eye pain.
\u2022\u00a0Three to five years before:\u00a0Emergency medicine and radiology visits increased.
\u2022\u00a0One year before:\u00a0Physician visits across multiple specialties peaked, including neurology, emergency medicine and radiology.<\/p>\n
\u201cThese patterns suggest that MS has a long and complex prodromal phase\u2014where something is happening beneath the surface but hasn\u2019t yet declared itself as MS,\u201d said Dr. Marta Ruiz-Alguer\u00f3, a postdoctoral fellow at UBC and the study\u2019s first author.<\/p>\n
\u201cWe\u2019re only now starting to understand what these early warning signs are, with mental health-related issues appearing to be among the earliest indicators.\u201d<\/p>\n
The study builds on\u00a0previous work\u00a0by Dr. Tremlett and her team to characterize the early stages of MS, or prodromal phase, when subtle symptoms appear before the hallmark signs become recognizable.<\/p>\n
Prodromal periods are well established in other neurological disorders, like Parkinson\u2019s disease, where mood changes, sleep disturbances and constipation often arise years before the more familiar motor symptoms like tremors and stiffness.<\/p>\n
While the researchers caution that the vast majority of people who experience general symptoms will not go on to develop MS, they say recognizing and characterizing the MS prodrome could one day help accelerate diagnosis and improve outcomes for patients.<\/p>\n
\u201cBy identifying these earlier red flags, we may eventually be able to intervene sooner\u2014whether that\u2019s through monitoring, support or preventive strategies,\u201d said Dr. Tremlett.<\/p>\n
\u201cIt opens new avenues for research into early biomarkers, lifestyle factors and other potential triggers that may be at play during this previously overlooked phase of the disease.\u201d<\/p>\n
