Twins with Mental Retardation and Physical Abnormalities Preliminary report

Abstract

In this preliminary report, which is part of a wider and more detailed study still in progress, I am reporting mainly the twins' mental state and associated physical abnormalities. For this purpose, I am surveying all the 2442 long-stay patients admitted during 30 years (1 September 1938-31 August 1968) to the Stoke Park Hospital Group, Bristol, which provides 1800 beds for mentally retarded patients of both sexes and of all ages. The survey's sample is shown in Tab. I.
