The prevalence of this condition stands at about 24 to 30 cases per 100,000 people while 0.7 to 3.0 new cases per 100,000 people are reported every year. Delusional disorder accounts for 1–2% of admissions to inpatient mental health facilities. [8] [31] The incidence of first admissions for delusional disorder is lower, from 0.001 to 0.003%. [32]
