Polio Effects Surfacing Decades Later

In the first half of the 20th century, polio was one of the most feared diseases in America. Paralytic polio causes pain and weakness in the arms or legs and problems with swallowing and breathing. This occurs when the polio virus attacks and kills motor nerve cells, which control muscles.

Since 1955, when the polio vaccine was introduced, the disease has all but disappeared in the United States. But in the early 1990s, patients who previously had polio and recovered began to report progressive pain and weakness in muscles and joints as well as increasing problems with fatigue.

Mayo Clinic researchers have been following a group of adults in Minnesota who had polio between 1935 and 1955 to learn more about the lingering effects of the disease. Researchers suspect that aging plays a role. "If you've already lost nerve cells in your youth because of polio and the remaining cells have been working twice as hard, you're going to have even more difficulties as you start to lose nerve cells to aging," says Anthony Windebank, M.D., neurologist and director of the Regenerative Neurobiology Program at Mayo Clinic in Rochester.

In addition, people may limp or walk differently because of polio damage and, as a result, be more prone to wear and tear and arthritis in the knees. Finally, people who've learned to compensate for polio-related problems may find that the compensation causes considerable fatigue.

There's no specific treatment for post-polio syndrome itself but most symptoms can be treated or managed. For patients who suspect polio is causing symptoms, the recommendation is to seek an evaluation with a provider who understands the illness and has experience treating neuromuscular disorders.

The polio virus, and its reign of terror in the American psyche, is faded history now. After a vaccine was introduced in the mid-1950s, millions of people sighed, turned the page and moved on. Many polio victims, often struck in childhood, tried to leave the story behind and forget, too.

So when Becky Lloyd, a researcher at the American West Center of the University of Utah, started an oral history project on polio last fall, she imagined weaving a tapestry of memory — a filling in of details about quarantines and rehabilitation units and hospital wards, with their rows of iron-lung breathing machines that became the most chilling symbols of the disease’s attack. Polio cases peaked in the United States in 1952.

But Ms. Lloyd soon found that polio’s past was not dead and gone. It was not even past. In all the early interviews, people talked about an after-echo legacy of the disease called post-polio syndrome that had come back to hit them in their 60s and 70s. Survivors who had battled through braces and operations decades ago wanted to talk about the present, Ms. Lloyd said, and the new battlefield they faced.

“Thirty, 40 or 50 years later, it’s like they’re getting the disease again,” Ms. Lloyd said.
