Previous estimates of incidence of stroke among American children (0.54 to 1.2 cases per 100,000) were underestimations. A new study reports that the frequency is actually two to four more than previously reported. Researchers at the University of California at San Francisco calculated from re-examination of hospital records and imaging data the actual incidence in the US to be 2.4 cases per 100,000. Another report from UK researchers give estimates that range from .3 per 100,000 to 13.0 per 100,000.
So why the underestimation?
Because health professionals still cannot easily accept the fact that stroke does occur in children.
In fact, everybody can suffer from stroke regardless of age. This ABC report describes a case of a baby who had stroke while still in the uterus. This event affected the boy’s motoric development. A neurologist performed a brain scan when the boy was 19 months old and arrived at a diagnosis: cerebral palsy due to a stroke in utero.
Aside from problems with diagnosis, health professionals also have to deal with the fact that most stroke treatments are only meant for adults.
In another case, a 15-year old presented with stroke symptoms. The hospital staff took the risk and treated with the clot buster drug tissue plasminogen activator (tPA). He recovered. But can tPA be used in younger kids, even infants? Nobody knows.
So what happens to kids who suffer from stroke? They suffer from the following:
- Neuromuscular disorders such as cerebral palsy
- Developmental disorders, including motoric and speech problems.
- Subsequent strokes
Childhood stroke is a neglected health problem even though research indicates that it is among the top ten causes of children mortality. Like in many disorders, the earlier a stroke is a diagnosed in children, the better are their chances to recover fully and live normal lives. The recent study American hopes to increase awareness and vigilance about stroke among children.
