The incidence of delusional disorders is approximately 0.7 to 3.0 cases per 100, 000 individuals annually. According to DSM-5 the prevalence of delusional disorder in the United States is estimated to be approximately 24-30 cases per 100, 000 individuals (0.02%), which is considerably lower than the prevalence of mood disorders(5%) and schizophrenia (1%). Females are more commonly affected with delusional disorder than males. Age at onset ranges from 18–90 years, with a mean age of 40 years.<ref name="wiki"> Delusional disorder.

Overview
The incidence of delusional disorders is approximately 0.7 to 3.0 cases per 100, 000 individuals annually. According to DSM-5 the prevalence of delusional disorder in the United States is estimated to be approximately 24-30 cases per 100, 000 individuals (0.02%), which is considerably lower than the prevalence of mood disorders (5%) and schizophrenia (1%). Females are more commonly affected with delusional disorder than males. Age at onset ranges from 18–90 years, with a mean age of 40 years.[1]
Epidemiology and Demographics
- Delusional disorder accounts for approximately 1-2% of admissions to inpatient mental health facilities. The incidence of first admissions for delusional disorder is approximately 0.001-0.003%. The lifetime morbid risk of delusional disorder has been estimated to range from 0.05 to 0.1 percent.[2]
- According to DSM-5, the estimated lifetime prevalence of delusional disorder is 0.2 percent, which is far lower than the estimated lifetime prevalence for other major psychotic disorders such as schizophrenia and bipolar I disorder with lifetime prevalence of 0.3 to 0.87 percent and 0.24 to 0.6 percent respectively.[3][4][2][5]
- Approximate rates of delusional disorder reported in samples of patients receiving mental health treatment have ranged from 0.5 to 1.2 percent. As the majority of people with delusional disorder do not regard it as an illness or receive treatment, studies likely underestimate the prevalence of the disorder. Delusional disorders are uncommon in psychiatric practice, though this may be an underestimation due to the fact that those afflicted lack insight and thus avoid psychiatric assessment.
Incidence
The incidence of delusional disorders is approximately 0.7 to 3.0 cases per 100, 000 individuals annually.[1]
Prevalence
According to DSM-5 the prevalence of delusional disorder in the United States is estimated to be approximately 0.02%, which is considerably lower than the prevalence of mood disorders (5%) and schizophrenia (1%).[6][7]
Gender
Females are more commonly affected with delusional disorder than males. The female-to-male ratio is approximately 2 to 1 (range: 1.18-3 to 1).
- Women are more likely than men to develop delusions of eromantia whereas men are more likely than women to develop paranoid delusions.[8][9][2]
Age
Delusional disorder commonly affects individuals in middle to late adult life. First admissions to hospital for delusional disorder occur between age 33 and 55 years of age. Age at onset ranges from 18–90 years, with a mean age of 40 years.[10]
