This trend is markedly more
evident for men compared with women. Overall,
the changes in IRR could perhaps be attributed to
more focus on child and adolescent psychiatric
disorders. For example, the introduction of Aspergers
syndrome and modification of the criteria of
hyperkinetic disorder in ICD-10 in 1994 in Denmark,
could have caused the more severe disorders,
such as schizophrenia, to be diagnosed proportionally
less often (36)
