While there are no figures on exactly how many children have misdiagnosed it is enough to cause concern. One example that seemingly shows misdiagnosis is in the case of children who enter school right at the cut off age. These children are younger than many of their classmates and are therefore often times more immature. There should be no link in cutoff age children and higher ADHD rates, yet large jumps in ADHD rates among these children are found. Hannes Schwandt explains that these jumps occur at different months across states in accordance with the different cutoff dates, indicating that the jumps in prevalence rates represent misdiagnosed rather than actual differences in children 's health which are unlikely to be spuriously correlated with the different cutoff dates across states (Schwandt,
