The aim of this retrospective study wasis to investigate whether current diagnostic procedures lead to earlier diagnosis of CP compared to a decade ago. Results were statistically significant and showed that children from the new cohort were diagnosed with CP at an earlier age (11 months), compared to children from the old cohort (19 months). However, it is not clear whether this was associated with the current diagnostic procedures. In fact, a great difference in terms of assessments performed on patients was found,; with GMsGMS, cUSCUS and visual examinationexaminations performed on almost on all patients of the new cohort, whereas none or very few patients from the old cohort had had them performed. Nonetheless, the SMILE Lab was only created in 2010 and patients from the old cohort were assessed in other institutions and their charts were missing data. Therefore, an equal comparison is not attainable and it is not possible to infer with certainty whether those assessments were performed or not. Furthermore, earlier diagnosis might have actually been the result of children receiving health care earlier and not of current diagnostic procedures, sincesince the age of referral to territorial services was lower in the new cohort than in the old one.
