Overview
Epidemiology and Demographics
Incidence
Prevalence
The prevalence is 1% in the general population, with 6 per 1000 persons having a severe mental disability. In the United States, individuals with a severe intellectual disability are at 0.3-0.5%, while worldwide prevalence is at 16.41 per 1000 people in developing countries and 9.21 per 1000 people in developed countries. Males are more likely to have a mental disability with a ratio of 2:1, and families with one child with severe mental disability have a recurrence risk of 3% and 9%. [1] [2]
Case-fatality rate/Mortality rate
- In [year], the incidence of [disease name] is approximately [number range] per 100,000 individuals with a case-fatality rate/mortality rate of [number range]%.
- The case-fatality rate/mortality rate of [disease name] is approximately [number range].
Age
- Patients of all age groups may develop [disease name].
- The incidence of [disease name] increases with age; the median age at diagnosis is [#] years.
- [Disease name] commonly affects individuals younger than/older than [number of years] years of age.
- [Chronic disease name] is usually first diagnosed among [age group].
- [Acute disease name] commonly affects [age group].
Race
- There is no racial predilection to [disease name].
- [Disease name] usually affects individuals of the [race 1] race. [Race 2] individuals are less likely to develop [disease name].
Gender
- [Disease name] affects men and women equally.
- [Gender 1] are more commonly affected by [disease name] than [gender 2]. The [gender 1] to [gender 2] ratio is approximately [number > 1] to 1.
Region
- The majority of [disease name] cases are reported in [geographical region].
- [Disease name] is a common/rare disease that tends to affect [patient population 1] and [patient population 2].
