Answered code queries
Q: When does three disease become apparent?
A: Up to 15 times before the formal treatment, the review found an increase in medical use related to MS signs.
Q: What initial signs did MS patients review?
A: Years before neurological symptoms, stress, problems, dizziness, anxiety, and depression started to appear.
Q: Why is this study significant?
A: It challenges conventional MS clinical timeframes and opens the door to earlier eradication and treatment strategies.
Summary: A comprehensive analysis of medical records reveals that multiple sclerosis ( MS ) subtle signs may appear more than a decade before diagnosis. 15 years before neurologists identified their first neurodegenerative event, people who later developed MS started making more frequent hospital visits, especially for common symptoms like exhaustion, pain, and anxiety.
These findings point to a protracted prodromal phase in MS, equivalent to early-stage Parkinson’s disease, where less recognized symptoms slowly come before less recognizable ones. This earlier time frame might be helpful for proactive monitoring, monitoring, and also developing prevention strategies.
Important Information
- Long Prodrome: Over the past 15 years, medical usage has increased rapidly.
- Early Warning Signs: Fatigue, dizziness, mental health issues, and vision problems were some of the first symptoms.
- Results challenge the idea that MS simply develops when neurological symptoms are present.

According to new research from the University of British Columbia, the first warning signs of multiple sclerosis ( MS ) may show up more than a decade before the first classical neurological symptoms manifest.
The study, which was published today in , JAMA Network Open, looked at the health information of more than 12, 000 persons in British Columbia and found that those with MS began using care services at inflated prices 15 times before their first MS symptoms started to manifest.
The results challenge long-held stereotypes about when the illness actually begins, providing the most detailed image to time of how people interact with a variety of healthcare providers in the years leading up to a treatment as they seek answers to ill-defined health issues.
According to senior author Dr. Helen Tremlett, professor of neurology at UBC’s faculty of medicine and investigator at the Djavad Mowafaghian Centre for Brain Health,” MS can be difficult to recognize as many of the earliest signs—like fatigue, headache, pain, and mental health concerns can be quite general and easily mistaken for other conditions.”
Our findings significantly alter the definition of when these early warning signs are likely to start, opening up the door to possible earlier detection and intervention.
The study used detailed medical history and clinical assessments to track physician visits in the 25 years leading up to a patient’s MS symptoms as determined by a neurologist.
It is the first study to look at how much of a patient’s clinical history was used to date. The majority of previous studies used administrative data to examine trends in the five to ten years leading up to a patient’s first demyelinating event ( such as vision problems ). This is a much later point of reference than the neurologist’s suggested start date for symptom onset.
People with MS experienced a steady increase in healthcare engagement over the course of 15 years, with the findings revealing that different types of doctor visits tended to rise over time as compared to the general population:
• 15 years prior to the symptoms began: • Visits to general practitioners rose, as did any physician visits for symptoms like fatigue, pain, dizziness, and mental health conditions like anxiety and depression.
• 12 years prior:  , Visits to a psychiatrist increased.
• Eight to nine years prior: • Increased visits to neurologists and ophthalmologists, which may have something to do with issues like blurry vision or eye pain.
• Three to five years prior:  , An increase in emergency medicine and radiology visits.
• One year prior: Physician visits to multiple specialties reached their highest level, including radiology, emergency medicine, and neurology.
These patterns suggest that MS has a lengthy and complex prodromal phase, in which it hasn’t yet formally formally formally formally formally formally formally formally characterized as MS, according to Dr. Marta Ruiz-Alguero, the study’s first author.
” These early warning signs are only now beginning to appear, with mental health-related issues posing as one of the earliest examples,” says Dr. Jones.
The study builds on Dr. Tremlett and her team’s previous work to characterize the early stages of MS, or prodromal phase, when subtle symptoms show up before the hallmark signs become recognizable.
Other neurological conditions, such as Parkinson’s disease, have prodromal periods well established, with which mood changes, sleep disturbances, and constipation frequently occur years before more common motor symptoms like tremors and stiffness.
The researchers say recognizing and characterizing the MS prodrome could one day help accelerate diagnosis and improve patient outcomes, despite the caution that the vast majority of people who experience general symptoms will not go on to develop it.
” By identifying these earlier red flags, we may eventually be able to intervene sooner, whether that’s through monitoring, support, or preventive strategies,” said Dr. Tremlett.
It opens up new avenues for studying early biomarkers, lifestyle factors, and other potential triggers during this previously untold phase of the disease.

Abstract
use of healthcare before the symptoms of multiple sclerosis start.
Importance
Before the onset of multiple sclerosis ( MS ), medical care use rises. However, the majority of studies have focused on the 5 to 10 years that followed the first demyelinating disease code based on administrative data. Few studies have looked at patterns before using clinical records to identify MS symptoms.
Objective
To examine the health care use in a clinical cohort from Canada’s British Columbia 25 years before the MS symptoms first appear.
Design, Setting, and Participants;
This prospective cohort study accessed data that was prospectively collected between January 1991 and September 2018. Midway through the year 2024, all data were made available for analysis. Using publicly available, publicly funded, and anonymous data from the British Columbia study. By sex, birth year, socioeconomic status, and postal code of residency, patients with MS were matched with up to 5 individuals who had already been identified from MS clinic records.
Main Results and Measures  ,  ,
Comparing physician visits 25 years before MS onset using adjusted negative binomial models and 15 years before MS onset by , International Classification of Diseases, Ninth Revision, ( ICD-9 ) chapter and physician specialty was based on Linked Clinical and Administrative Data.
Results
A total of 2038 patients with MS ( mean]SD] age at symptom onset, 37.9]10.9] years, 1508 female]74.0 % ] ) and 10 182 matched individuals were included. All-cause physician visit rate ratios ( RRs ) for patients with MS were consistently elevated from 14 years before onset ( adjusted RR]ARR], 1.19, 95 % CI, 1.07-1.33 ), peaking the year before MS onset ( ARR, 1.28, 95 % CI, 1.21-1.35 ).
The RRs for poorly defined symptoms and signs were consistently higher 15 years prior to onset, exceeding 1.15, and reaching 1.37 (95 % CI, 1.19-1.56 ) the year before MS onset. Mental health–related RRs from 14 years before onset were significant ( excluding years 7, 5, and 4), with RRs in the 3 years before MS onset ranging from 1.30 (95 % CI, 1.05-1.58 ) to 1.38 (95 % CI, 1.12-1.68 ).
The year before MS onset, the RRs for sensory, musculoskeletal, and nervous system concerns were elevated by 8, 5, and 4 years, respectively, with, for instance, a peak of 2.42 (95 % CI, 1.90-3.07 ) at 2.42 (95 % CI, 1.90-3.07 ). General practice visit RRs were significantly higher in each of the 15 years prior to the onset of MS, reaching 1.23 (95 % CI, 1.17-1.30 ) in the year before onset.
Psychiatry visit RRs were elevated 12 years before onset ( 2.59, 95 % CI, 1.23-5.47 ). The ratios between neurology and ophthalmology were significantly higher up to 8 to 9 years before onset, peaking at 5.46 (95 % CI, 4.30-6.93 ) for neurology and 1.64 (95 % CI, 1.30-2.08 ) for ophthalmology, at 5.46 (95 % CI, 4.30-6.28 ) for both groups.
Conclusions and Relevance  , ,
In this matched cohort study of MS patients and MS patients, the prevalence of health care use was higher between 14 and 15 years prior to the onset of MS symptoms, suggesting that MS may have begun earlier than previously thought. Among the earliest features of the prodromal period before neurologic and system-related visits by 7 to 11 years are psychiatric issues, as well as ill-defined signs and symptoms.
