Former Paralympian has 'brand new body' with new diagnosis, new treatment

When she was two years old, doctors diagnosedDanielle Campo McLeodof Tecumseh, Ont. withmuscular dystrophy.

"It was so extreme," she said. "The muscle weakness in my legs madethings like walking, jumping, and climbing up stairs difficult. I would fall. I would fall often. I couldn't climb up a flight of stairs without using my arms."

When she was seven, she started swimming lessons and she would go on to become a world-class athlete. She won a total of seven medals representing Canada at the 2000 and 2004 Paralympic Games in Sydney, Australia and Athens, Greece. She also won multipleworld championship gold medals and set world records.

But she recently learned she doesn't have muscular dystrophy after all, and it's led toa remarkable physical transformationsomething she never thought possible.

"The joke is now I'm breaking things around our house and destroying things because I have strength in my hands I've never had before, so the effort I am used to using ... is causing things to break,"Campo McLeodtold CBC Windsor Morning's Tony Doucette.

"The most amazing thing, from a physical standpoint, is I don't have any more fatigue or pain."

The big change happened June 24 when Campo McLeodgot an unexpected call from her doctor.

"I was standing in our new social distancing world,in line waiting to get into a store, and my phone rang and I answered it," she said."And so he said 'what I'm telling you Danielle is I found something that I believe means that you have a rare auto immune disorder. And the next news is really exciting. There'streatment and you can start that treatment in a week.'"

Her new diagnosis is congenital myasthenic syndrome [CMS].

She started taking medication for CMS on July 2 and Campo McLeodsaysit's like having a "brand new body." She is enjoying living without the pain.

"It was just the way my body was it's been like this since I was two years oldI've always had fatigue,I've always had pain, and I just assumed I thought your feet hurt everyday too," she said.

"My pain has been decreasing every day to the point that, you know, like I said I'm busy."

Campo McLeodand her husband Dennis, who live in Windsor, have been testing just how far her body can go by video recording simple things like how high she can jump, and comparing the before and after videos.

"Ican play on the floor with my kids. I can get down onto the floor and play with them," she said.

She and her husband have four children, threeboys and a girl, ranging from 15 years old down to 15 months.

"We had my youngest baptized lastSaturday and I was walking across the parking lot and my mom said 'I don't even recognize you when you're walking away from me. I don't even recognize [how] you're walking now.'"

We know that people get misdiagnosed. It takes a long time to find the right diagnosis. In my case it was 35 years,- Danielle Campo McLeod, former Paralympic gold medallist

Although she is unsure what the future may hold and she still has a lot of progress to make,Campo McLeodsaid the strength she has gained so far is incomparable to what she could ever have imagined for herself.

"I don't worry that I'm not going to get to see my [children]grow up," she said. "What a thing, to take away the fear."

Hard to find gene mutation

Despite the misdiagnosis, Campo McLeod says she does not blame her "excellent" doctor or the medical professionals she's worked with because of the complexity of muscular dystrophy.

"We know that people get misdiagnosed. It takes a long time to find the right diagnosis. In my case it was 35 years," she said. "I owe this to my doctor because he never gave up."

Dr. Mark Tarnopolsky, research director of the neuromuscular and neurometabolic diseaseclinic atMcMaster University has been working withCampo McLeodfor more than a decade.

He was the one to determine what she had.

"Many years ago what we would do isa muscle biopsy, and we would use different proteins and take a look. And that allowed us to diagnose probably a dozen different types of muscular dystrophy. And that was 20, 30 years ago," he explained. "But in Danielle's case, and many others, the muscle biopsy just showed nonspecific features."

Gene testing makes it possible for doctors to find out more specifics in relation to muscular dystrophy, but it is a lengthy and expensive process said Tarnopolsky.

In Campo McLeod's case, there was a specific gene mutation that was very noticeable to her doctor and it is treatable.

Tarnopolsky said there have been huge improvements when it comes to research to help those with muscular dystrophy.

"For her, this gave us a whole new approach to therapy whichgave her quite a dramatic improvement," he said."This was such a rewarding experience for her and obviously that makes us extremely pleased because our goal is to improve function in these patients."

"I never expected this day in my life," said Campo McLeod."It's crazy."
