T145. Association Between Hand Digit Ratio and Bipolar Disorder

The 2nd- to 4th-finger ratio (2D:4D) has been proposed as a potential indicator of greater androgen exposure during fetal development. While smaller digit ratios, suggestive of stronger perinatal androgen action, have been associated with male-linked disorders (e.g., autism), problematic video gaming behavior, larger digit ratios, suggestive of weaker perinatal androgen action, have been associated with depression, schizophrenia, and eating disorders. We investigated association between the (2D:4D) and bipolar disorder.
