Multiple sclerosis may begin far earlier than previously thought. Canadian researchers have decoded that the earliest warning signs of the immune system disorder may emerge more than a decade before the first classical neurological symptoms occur.
The findings, published in JAMA Network Open, 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 health care providers in the years leading up to a diagnosis as they search for answers to ill-defined medical challenges.
"MS can be difficult to recognise as many of the earliest signs -- like fatigue, headache, pain and mental health concerns -- can be quite general and easily mistaken for other conditions," said senior author Dr. Helen Tremlett, Professor of neurology at the University of British Columbia.
"Our 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," she added.
