The Multiple Sclerosis Association of America is proud to introduce the latest edition of The Motivator, available now in both print and digital editions! This edition’s cover story, “Revealing the Mysteries behind Magnetic Resonance Imaging (MRI),” covers how an MRI works, what it shows, the challenges it presents, and how the MRI is used to monitor disease activity.

Read an excerpt from our cover story here:

MS can sometimes be “clinically silent,” where active lesions are not causing any symptoms. However at other times, certain lesions observed through an MRI correspond specifically to some type of dysfunction, depending on where the lesion is located. For instance, a lesion on the optic nerve may cause optic neuritis, while a lesion on the brainstem can cause vertigo and/or double vision.

Lesions along the spinal cord cause very specific symptoms depending on their location, but in general, these typically relate to either motor (movement) or sensory (sensation) problems. When lesions occur within the anterior (front) portion of the spinal cord, motor or movement functions are affected. Difficulty with coordination and strength with moving one’s arms or walking are examples of symptoms that may occur. When lesions occur within the posterior (back) portion of the spinal cord, sensory problems are more likely. These might include numbness, tingling, burning, and/or loss of feeling, month other sensory issues.
