Abstrakt:	Objective: To compare fingerprint patterns, means of dermatoglyphic variables i.e., total finger ridge count, total a-b ridge count, pattern complexity index, and fingerprint pattern asymmetry between patients with schizophrenia and normal controls. Material and Method: A cross-sectional, matching case-control was conducted. Thirty-four males and 34 females with schizophrenia and an equal number of age and sex matched normal controls were selected. Fingerprints and partial palm prints of all of the subjects were obtained using the Automated Inkless Fingerprint Imaging Software and the transparent-adhesive tape technique, respectively. Using paired t-tests (p < 0.05), the cases and controls, males and females separately, were compared for fingerprint pattern asymmetry, total finger ridge counts (TFRC), a-b ridge counts of the right (RABRC), left (LABRC), and both hands (TABRC), and pattern complexity index (PCI). Results: Between cases and controls, neither sex had any significant differences in the mean scores for the pattern asymmetries, TFRC, right-left-ABRC and TABRC. However, the mean scores for PCI were significantly different between the male cases and controls (2.82 vs. 4.94, p = 0 009). Conclusion: Only male patients exhibited average scores for complex patterns (whorls minus arches less than 2), which might be a biomarker for screening of schizophrenia in males.
