The most feared complication of ITP is intracranial hemorrhage, a bleed to the brain, like a stroke. Fortunately, this is rare, occurring in less than .5 to 1.0% of the children diagnosed with ITP.
About 4.3 to 5.3 per 100,000 children are diagnosed with ITP each year.1,2 Since children with ITP usually recover, the number of children who have ITP at any one time is about equal to those diagnosed annually.3
Since ITP is a diagnosis of exclusion, it is important to rule out other causes of low platelets and tell the doctor about events that could have triggered the low platelets.

Treatments
The treatments for ITP in children can vary depending on the child’s platelet count, activity level and bleeding symptoms. Whatever the treatment regimen, it is important for the child to have as normal a life as possible. Because many children recover and the treatments can be difficult, some pediatric hematologists suggest a watchful waiting approach. New treatments for children are in Clinical Trials.Vaccinations
About one in every 25,000 MMR vaccinations will result in a diagnosis of ITP4. For information on informed vaccine decisions, visit:The National Vaccine Information Center
