Relapsing-remitting MS

Relapsing-remitting multiple sclerosis (RRMS) is the most common disease course of multiple sclerosis. It is characterized by clearly defined attacks of new or increasing neurologic symptoms, followed by periods of partial or complete recovery (remissions).

Symptoms

Symptoms of RRMS can vary widely and may include fatigue, difficulty walking, numbness or tingling, muscle spasms, weakness, problems with coordination and balance, and more. These symptoms are caused by inflammation and damage to the myelin sheath, the protective covering of nerve fibers in the central nervous system, which disrupts the flow of electrical impulses along the nerve fibers.

Diagnosis

Diagnosis of RRMS is typically based on a combination of patient history, physical examination, magnetic resonance imaging (MRI), and sometimes lumbar puncture (spinal tap). The McDonald criteria are commonly used to diagnose RRMS and other forms of MS.

Treatment

While there is currently no cure for RRMS, there are several disease-modifying therapies (DMTs) available that can help to reduce the frequency and severity of relapses and slow the progression of disability. These include injectable medications, oral medications, and infused medications.

Prognosis

The course of RRMS can be unpredictable. Some people may experience only a few mild symptoms, while others may develop significant disability. Most people with RRMS eventually develop a more progressive form of the disease, known as secondary progressive multiple sclerosis (SPMS).
