What is primary progressive multiple sclerosis?
Multiple sclerosis (MS) is a neurodegenerative disease. It interferes with your brain’s ability to control your body. It can be disabling.
There are 4 main types of MS:
Relapsing-remitting MS (RRMS)
Primary progressive MS (PPMS)
Secondary progressive MS (SPMS)
Each type may be mild, moderate, or severe. Each type affects people differently.
With PPMS, nervous system problems get worse from the beginning. There are no symptom flare-ups (relapses or attacks). And there is no recovery (remission). How fast the disease gets worse may vary. There can be times when things are stable. And there can be periods of short-term (temporary) minor improvements. But nervous system problems steadily get worse.
Men and women are evenly affected by this type of MS.
About 1 in 10 people diagnosed with MS have PPMS. On average, people with PPMS start having symptoms between ages 35 and 39.
What causes primary progressive MS?
Doctors don’t know the exact cause of MS. It may develop when your immune system attacks a substance called myelin.
Myelin acts as a type of insulation for your nerve cells. This process can lead to damage in and around the nerves in your brain and spinal cord. It can also damage nerves used for vision.
What are the symptoms of primary progressive MS?
Symptoms can be a bit different for each person. Symptoms can include:
Pain, such as pain in the legs and feet, back pain, and muscle spasms
Electric-shock sensations that run down the back and limbs when the neck is bent (Lhermitte sign)
Trouble staying balanced
Trouble thinking clearly
Trouble with bowel and bladder control
How is primary progressive MS diagnosed?
Methods that your healthcare provider may use to diagnose MS include:
Discussion. Your healthcare provider will talk with you about your symptoms.
Physical exam. This is done to see how your nerves and muscles are working.
MRI scans of your brain and spinal cord. These images will help your healthcare provider look for signs of damage that suggest MS.
Optical coherence tomography (OCT). This test measures nerve fibers in the retina.
Blood work. This is to look for infections or health conditions that can look like MS.
Spinal tap (lumbar puncture). Your healthcare provider removes a sample of spinal fluid to check for signs of MS.
Visual evoked potentials (VEP). This test is done to see how well your optic nerves are working.
After the general diagnosis of MS, the diagnosis of PPMS is based almost entirely on your symptom history. Because of this, it may take time for the PPMS diagnosis to be made.
How is primary progressive MS treated?
Oocrelizumab is currently the only medicine approved to treat primary progressive MS.
Your healthcare provider will also try to provide treatments that ease symptoms and improve your quality of life. These may address problems such as depression, sexual problems, and extreme tiredness (fatigue).
How can I prevent primary progressive MS?
Experts don’t know how to prevent MS or the PPMS type of MS. Some people limit MS relapses by staying away from certain triggers such as stress and overheating.
How do I manage primary progressive MS?
Physical and occupational therapy may be helpful. For example, therapists may teach you exercise strategies and how to manage new symptoms that develop. Your healthcare provider will also likely want to meet with you on a regular basis to check your disease.
Regular exercise and plenty of sleep may also help. If your body temperature goes up, it may make your symptoms worse for a short time. So it’s best to not do things that could lead to overheating. This includes spending long periods of time in the sun or overexerting yourself.
Managing MS can be difficult, frustrating, and frightening. If you have feelings of anxiety or depression, ask your provider for help. Support groups for patients and families, and individual therapy, can help people deal with the challenges and changes that people with MS and their loved ones face.
