The medical term 'prevalence' of Sleep disorders usually refers to the estimated population
of people who are managing Sleep disorders at any given time,
whereas the annual diagnosis rate of new cases of Sleep disorders is called the 'incidence'.
For more information on prevalence and incidence statistics, see about prevalence and incidence statistics.
