The current study examined whether relatively young children are more likely to be diagnosed with specific learning disorders than their older peers by following nearly 390,000 singleton children born in Finland between 1996 to 2002. The data was retrieved through Finnish birth and healthcare records. Of the children born alive in Finland in these years, 3,860 (1.0%) were diagnosed with a specific learning disorder by the age of 10, and the median age at first diagnosis was 8.4 years.
