age of onset

An increasing number of people in western Norway have been diagnosed with relapsing-remitting multiple sclerosis (RRMS) after age 50 over the past century, according to a new population study. The rise was primarily driven by people being diagnosed at older ages, with the average age of onset rising from 28.6…

People with primary progressive multiple sclerosis (PPMS) at younger ages are more likely to have higher disease activity, suggesting they may respond better to disease-modifying therapies, according to a review of published studies. “Our findings confirm that younger patients tend to have more inflammatory activity, and so younger…

Researchers have identified early factors that can affect the trajectory of a patient’s long-term health-related quality of life (HRQoL) after a multiple sclerosis diagnosis. These factors include older age, worse physical impairment, and more severe fatigue at diagnosis, which were predictive of worse long-term physical HRQoL. In addition,…

People with a higher genetic risk for multiple sclerosis (MS) are significantly more likely to develop the disease at an earlier age, a large study found. Specifically, those with the highest genetic risk were on average five years younger at the time their symptoms started than those with the…

Marked differences in disease characteristics are observed between male and female patients with multiple sclerosis (MS) but they are more pronounced when comparing patients across clinical subtypes, a new study finds. The analysis found that although women are more prone to…

A large international research effort concluded that the geographical area where a person lives affects how early they will start showing symptoms of multiple sclerosis (MS), and that people living in the more northern regions having the earliest disease onset. The age at which a person fell ill also was…
