Cerebral palsy is an umbrella term for motor impairments that share features of a non-progressive brain injury, acquired during the early stages of its development [1]. The motor impairment is often associated with visual and hearing deficits as well as epilepsy and intellectual disability [1-5]. To monitor prevalence rates, especially within subgroups, it was considered necessary to study large populations. Registers for cerebral palsy were therefore established. The Danish cerebral palsy Register include children born from 1950 [6] and the western Swedish cerebral palsy register include children born from 1954 [7].
