In a study of 357 long-stay hospital residents aged 40 years and over, 30% had significant psychiatric disorder, while a retrospective survey of 215 new admissions over a seven-year period to a psychiatric unit for the mentally handicapped revealed that 20% of patients were aged 40 years and over. Both similarities and differences were found in the overall pattern of disorders between the two groups and a non-handicapped population in a comparable age-range.
在一项针对357名40岁及以上长期住院患者的研究中，30%的患者患有严重精神疾病，而一项对一家智障人士精神科病房七年间215名新入院患者的回顾性调查显示，20%的患者年龄在40岁及以上。两组患者与年龄范围相当的非智障人群在疾病总体模式上既有相似之处，也有不同之处。
