Progressive Relapsing Multiple Sclerosis
If you have
progressive relapsing multiple sclerosis (PRMS), your condition will get steadily worse from the very beginning.
But you also will experience distinct relapses, with or without full recovery. Between relapses, the disease continues to gradually worsen.
Types of Multiple Sclerosis
PRMS is the least common type of
multiple sclerosis. It affects about 5% of all people with MS.
Symptoms of Progressive Relapsing MS
No two people are likely to have the same set of MS symptoms in the same way. Some symptoms may come and go or appear once and not again. The symptoms you have depend on the area of the
brain or spinal cord damaged.
The symptoms of PRMS may include:
A relapse can last anywhere from 24 hours to several weeks. During a relapse new symptoms occur or old symptoms temporarily worsen.
In PRMS, relapses may or may not be followed by some recovery. But there are no remissions.
Tell your doctor about a relapse as soon as possible. Treating it quickly may reduce permanent damage and disability.
Treatment With Disease-Modifying Drugs
People with PRMS take
medications called disease-modifying drugs (DMDs). These drugs reduce the frequency and severity of relapses. They work by dulling the body's immune system.
DMDs may slow disease progression. This treatment may also be called immunotherapy or disease-modifying therapy (DMT). It is the cornerstone of treatment for most types of MS.
Several DMDs are taken by self-injection. These include:
Other DMDs require intravenous (IV) injection that is done at a clinic or hospital. They include:
More recently, three oral disease-modifying drugs were approved for MS. They are:
Aubagio (teriflunomide) Gilenya (fingolimod) Tecfidera (dimethyl fumarate)
All of these drugs have side effects, some more severe than others. Your doctor will want to monitor you closely and weigh the risks and benefits of each drug.
