ABO blood groups in obsessional illness – state and trait

Abstract
Evidence for an association between ABO blood groups and obsessive-compulsive neurosis was reported. This hypothesis and the relationship between ABO phenotypes and personality traits in obsessive-compulsive neurosis were examined. ABO blood types in 70 patients with obessive-compulsive neurosis was determined and their distribution compared with that of a blood donor population. Premorbid personality was rated in 56 of the patient sample using a close relative as informant. An association between ABO phenotypes and obsessive-compulsive neurosis or premorbid personality traits was not shown. Previous positive findings and general criticisms of blood group-disease association studies are discussed.
