7MM multiple sclerosis-diagnosed cases to reach 1.64 million by 2033

Japan is expected to have the lowest count at 31,527 cases.

The diagnosed prevalent cases of multiple sclerosis (MS) in the seven major markets (7MM) are projected to rise from 1.61 million in 2024 to 1.64 million by 2034, amidst an annual decline of 0.19%, according to GlobalData.

The US is forecasted to experience the greatest number of diagnosed prevalent cases of MS amongst the major markets at 896,828 cases, whilst Japan is expected to have the lowest count at 31,527 cases.

Meanwhile, adults aged 50–59 years accounted for the highest proportion of the diagnosed prevalent cases of MS in 2024, said Rahul N Ravi, MPH, Senior Epidemiologist at GlobalData.

“Early diagnosis of MS has increased over the past few decades. The availability of neurologists and diagnostic tools has a strong link to MS diagnosis,” Ravi added.
