Relationship between dermatoglyphie patterns in bipolar I disorder and schizophrenia

Background and purpose: Dermatoglyphie patterns and nervous system share a common stem and genetic basis. Accordingly the aim of this study was to investigate the relationship between schizophrenia and bipolar disorder, and dermatoglyphie patterns. Materials and methods: The fingerprint patterns of 100 patients with bipolar I disorder (BID), 100 patients with schizophrenia (SCH) and 100 healthy controls (Control Group: CG) were analyzed and compared in this case-control study blindly. Results: The frequency of whorl pattern was higher in BID group than in CG group (P<0.03). The frequency of arches in SCH group was less prevalent than that in CG (P<0.002). Dermatoglyphie analysis showed only significant differences in the 2nd and 3rd finger of the left hand between BID and CG (P<0.02 and P<01 respectively). The difference was also significant in the 1st and 4th finger of the right hand as well as in the 4th finger of the left hand between SCH and CG (P<0.04, P<04, and P<02 respectively). Dermatoglyphie pattern of the BID and SCH patients was not significantly different. Conclusion: Higher whorl pattern in the 2nd and 3rd finger of the left hand and lower arches in the 1st and 4thfinger of the right hand as well as in the 4th finger of the left hand may be associated with BID and SCH respectively. There is no significant difference between dermatoglyphie pattern of BID and SCH for clinical use. Key words: Dermatoglyphics, schizophrenia, bipolar I disorder
