[Aphasia in the Netherlands; extent of the problem]

This article reports on a study of the frequency of aphasia in the Netherlands. Using information obtained from a survey of the literature and data from Dutch Sources, we estimated that in 1979 the incidence must have been about 3500 cases and the prevalence about 5100 cases (the first 2 months of the disease and, with regard to the prevalence the period after 2 years, were left out of consideration). Because of some uncertainties these figures must be considered to be crude estimates of the extent of the aphasia problem in the Netherlands.
