Among the cycloid psychoses, nine of 11 monozygotic pairs with motility psychoses were concordant (82%). Of the two discordant pairs the ill index-twin was the second-born, more susceptible to mental strain and in one case suffered from severe asphyxia during birth. Among the concordant pairs no essential differences could be detected between the two partners based on the birth histories. In many cases, however, either one or both partners had suffered birth complications. In five of nine cases the second-born and mentally more unstable twin became ill earlier and/or more severely.
