Children at risk of multiple sclerosis often go undetected in early stages: Study finds detection tools used for at-risk adults fail to predict the neurological disorder in young patients

Magnetic resonance imaging (MRI) is the primary tool used for diagnosis of MS.

Doctors have applied various standards over the years to classify those most likely to develop MS.

The most recent standard, known as the McDonald criteria, was last updated in 2017.

In some cases, imaging suspicious for MS is found incidentally before the disease manifests.
