Types of MS
There are four types of multiple sclerosis, each with different symptoms, the diagnosis and treatment being established depending on their severity.
- Relapsing-remitting multiple sclerosis
- Secondary-progressive multiple sclerosis
- Primary-progressive multiple sclerosis
- Relapsing-progressive multiple sclerosis
Relapsing-remitting MS is the most common type of the disease being diagnosed in many patients. In this stage, patients have symptoms that stop after a period. This is called remission. The episodes last from a few days to a few weeks and symptoms may improve partially or completely. The frequency and severity of the flare-ups vary from one patient to another. Onset of the disease at a younger age is associated with a better long-term outcome.
Secondary progressive multiple sclerosis is a more advanced stage of the disease and develops in patients who have already been diagnosed with the early phase of MS. The transition between the two is gradual and can vary in duration. Patients may experience a progressive deterioration of motor, cognitive, and sensory functions. This type of MS can be active or inactive. In the active phase, new lesions can be seen on medical examinations, while the inactive phase shows no signs of inflammation.
Primary progressive MS is characterized by constant worsening of symptoms, without remissions, leading to walking difficulties and balance problems. Unlike the other forms of multiple sclerosis, primary progressive multiple sclerosis affects gender equally.
Relapsing-progressive MS is less common and is manifested by constant worsening of symptoms. Pediatric multiple sclerosis is rare.
