when her young daughter holli was not meeting her gross motor development milestones – things like sitting without support or rolling over from front to back – susi vander wyk took her repeatedly to her doctor to find out if there was anything wrong.
eventually, a genetic test revealed holli had spinal muscular atrophy, or sma, an inherited motor neuron disease where specialized cells in the spinal cord and brain don’t function properly. motor neurons affect the voluntary muscles used for crawling, walking, head and neck control and swallowing.
there’s no cure for sma. it gets progressively worse, like other neurodegenerative chronic diseases such as parkinson’s disease and multiple sclerosis. parents like susi in chilliwack, b.c., have to stay strong as they watch muscles weaken, and their child needs more support.
“at that time, i was pregnant, so i had a son who was two, and then holli was diagnosed with sma, and they said my unborn baby could have a one in four chance of having it as well. it was a terrible time,” says susi who was told holli would never walk or live past age eight. “for many years, you know, they said there’s nothing that can be done. you just take your baby home and love them for as long as you’ve got them.”
although sma is mainly diagnosed in childhood – about one in 6,000 babies are born with sma – there are cases of adolescent and adult-onset sma that cause muscle weakness, trouble breathing and fatigue. the earlier symptoms appear, the more severe the disease. intellectual activity is normal with sma, and sensation and the ability to feel are not affected.
genetic tests showed that susi’s son and unborn child did not have sma. she chose to turn her fear into determination and joined other families to fundraise for sma research in canada. for the last 14 years she has served as executive director of the parent group that eventually became
cure sma canada. the organization is the go-to for family support and community and is where patients and their families are typically referred by health-care providers. fundraising and advocacy by susi and her colleagues have helped bring new treatments for sma to canadians, including her daughter.
