This article reviews the demographic characteristics of paranoid psychosis or delusional disorder (DD) and compares them with those found for schizophrenia and affective illness. Delusional disorder constitutes between 1% and 4% of all psychiatric admissions, with an incidence of first admissions between 1 and 3/100,000 population per year. Like affective illness, but unlike schizophrenia, DD is predominantly an illness of middle to late adult life, usually occurring in persons who have been married. Like schizophrenia, but unlike affective illness, DD occurs more frequently in low socioeconomic classes and produces a poor chance for full recovery. Delusional disorder occurs more frequently than either schizophrenia or affective illness in immigrants. From a demographic perspective, DD closely resembles neither schizophrenia not affective illness.
本文回顾了偏执型精神病或妄想障碍（DD）的人口统计学特征，并将其与精神分裂症和情感性疾病的特征进行比较。妄想障碍占所有精神科住院病例的1%至4%，首次住院发病率为每年每10万人中有1至3例。与情感性疾病一样，但与精神分裂症不同，妄想障碍主要是成年中后期的疾病，通常发生在已婚人士中。与精神分裂症一样，但与情感性疾病不同，妄想障碍在社会经济地位较低的阶层中更常见，且完全康复的机会很小。妄想障碍在移民中比精神分裂症或情感性疾病更常见。从人口统计学角度来看，妄想障碍与精神分裂症和情感性疾病都不太相似。
