    Article - En anglais


    Although the evolution of the prevalence of cerebral palsy is now well documented, much less is known about the evolution of the prevalence of other disabilities such as mental retardation, sensorial defects, autism and psychosis.

    This decrease was significant for severe mental retardation associated with psychosis.

    The time trend prevalence for cerebral palsy increased (P 0.03) but was irregular.

    The time trend prevalence of other disabilities (other motor defects, severe sensorial disabilities, autism and psychosis) did not change significantly.

    A detailed analysis of severe mental retardation and cerebral palsy was performed by geographical area, age at first registration and type of disability.
