when caregivers contact muscular dystrophy canada (mdc) following a child’s diagnosis with a neuromuscular disorder like spinal muscular atrophy (sma), there’s no one-size-fits-all approach to providing support.
“we take an individualized approach with each family because we know that there are a lot of factors that can influence decisions, whether it be the province you reside in, your health-care team or your family circumstances,” says homira osman, mdc’s vice president of research and public policy.
each year, approximately one in 13,000 babies is born with sma, a rare genetic disease that causes progressive muscle weakness over time. sma is characterized by the gradual loss of motor neurons that are responsible for controlling actions such as walking, breathing and swallowing.
“in its most severe form, infants and children with sma would pass away by their second birthday,” says osman. “some infants wouldn’t be diagnosed until they ended up in the emergency room or in the intensive care unit as a result of a respiratory or cardiac complications.”
how newborn screening is changing lives
with an sma diagnosis, there’s a short window of opportunity to slow the progression of the disease, making early diagnosis imperative. in an effort to improve early access to care for infants born with sma, mdc and its partners spent the last few years advocating for sma to be added to existing newborn screening programs across canada. blood samples for newborn screening are collected up to 48 hours after birth and tested for multiple treatable diseases, all before symptoms appear.
