syndrome is an illness of the
nervous system that can appear 15 to 50 years after you
polio. It affects your muscles and nerves, and it
causes you to have weakness, fatigue, and muscle or joint pain.
Although post-polio syndrome can make some day-to-day activities more difficult, treatment can help control symptoms and help you stay active. Your symptoms may not get worse for many years. Post-polio syndrome usually progresses very slowly.
Only people who
have had polio can get post-polio syndrome. But having post-polio syndrome
doesn't mean that you have polio again. Unlike polio, post-polio syndrome doesn't spread from person to person.
Post-polio syndrome most likely
arises from the damage left over from having polio.
virus harms the nerves that control muscles, and it makes the muscles weak. If
you had polio, you may have gained back the use of your muscles. But the nerves
that connect to the muscles could be damaged without your knowing it. The
nerves may break down over time and cause you to have weak muscles
Researchers are studying other possible causes of
post-polio syndrome. One theory is that the
immune system plays a role.
Symptoms of post-polio
syndrome tend to show up very slowly. The main symptoms are:
Depending on which muscles are affected, this trio of muscle weakness, fatigue, and pain can make daily activities more difficult. For example, people with shoulder or arm weakness may have trouble getting dressed. People who have weakness in their legs may have trouble walking or climbing stairs.
Some people who have post-polio syndrome
also have problems with swallowing, sleeping, and tolerating cold
temperatures. Or they may need help to improve their breathing.
Doctors diagnose post-polio syndrome based on your symptoms, medical history, and lab tests. Your doctor will look at how polio affected you and how well you healed from
it. Lab tests will be done to check for other causes of your symptoms. If your symptoms and history point to post-polio syndrome, and if tests cannot find another cause, then your doctor may diagnose post-polio syndrome.
need to have more tests or exams if your symptoms change.
Post-polio syndrome is a
condition that you may have for the rest of your life. The goal of treatment is to help you control symptoms and learn ways to stay active in spite of your
muscle weakness. Here are some things you can do to stay active and feel better:
If your condition gets worse, your treatment needs may increase. Be sure to see your doctor whenever new symptoms occur or your symptoms get worse.
is common in people who have post-polio syndrome, as with many long-term illnesses. But it may be hard to recognize, because symptoms of fatigue, low energy, and sleep problems can occur
with both conditions. If you think you may be depressed, talk to your doctor. Treatment can often greatly improve
symptoms of depression.
Not everyone who had polio gets post-polio syndrome. It's hard
to predict who will get symptoms, when symptoms will begin, and how severe they
will be. The exact amount of time it takes for symptoms to start is different
for each person. Symptoms may have started as soon as 15 years after you had polio.
You are more
likely to get post-polio syndrome if you:
It's hard to know how many adults who had polio will get post-polio syndrome. The symptoms (such as fatigue and weakness) are sometimes ignored or considered part of "normal aging." Between 2 and 4 out of 10 adults who had polio may get post-polio syndrome.1
Learning about post-polio syndrome:
The National Institute of Neurological Disorders and
Stroke (NINDS), a part of the National Institutes of Health, is the leading
U.S. federal government agency supporting research on brain and nervous system
disorders. It provides the public with educational materials and information
about these disorders.
The March of Dimes tries to improve the health of babies
by preventing birth defects, premature birth, and early death. March of Dimes
supports research, community services, education, and advocacy to save babies'
lives. The organization's website has information on premature birth, birth
defects, birth defects testing, pregnancy, and prenatal care.
The Post-Polio Health International (PHI) helps people
with post-polio syndrome get information and exchange information about the
condition. PHI also offers a newsletter, brochures, and a handbook for doctors
and patients on the long-term effects of polio.
