▲Top About extrapolations of prevalence and incidence statistics for Aphasia:
These statistics are calculated extrapolations of various prevalence or incidence rates against the populations of a particular country or region. The statistics used for prevalence/incidence of Aphasia are typically based on US, UK, Canadian or Australian statistics. This extrapolation calculation is automated and does not take into account any genetic, cultural, environmental, social, racial or other differences across the various countries and regions for which the extrapolated Aphasia statistics below refer to. As such, these extrapolations may be highly inaccurate (especially for developing or third-world countries) and only give a general indication (or even a meaningless indication) as to the actual prevalence or incidence of Aphasia in that region.
▲Top About prevalence and incidence statistics in general for Aphasia:
The word 'prevalence' of Aphasia usually means the estimated population of people who are managing Aphasia at any given time (i.e. people with Aphasia). The term 'incidence' of Aphasia means the annual diagnosis rate, or the number of new cases of Aphasia diagnosed each year (i.e. getting Aphasia). Hence, these two statistics types can differ: a short disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence.
