Resumen de Biomarkers of mental illness and the human hand: A systematic review
Background and Objectives Biomarkers on the hands have been associated with a range of physical and mental health conditions. To systematically evaluate the evidence of dermatoglyphics, digit ratio and palmar crease hand biomarkers in relation to mental illness.
Methods Web of Science, Scopus and MEDLINE were searched for eligible studies, the review was performed according to PRISMA.
Results 29 papers comprising of 13,030 participants were selected. Palmar crease research presented the most consistent correlations. Dermatoglyphics presented significant findings, although there were specific biometric inconsistencies in some results. Digit ratio produced the least consistent results, with some non-significant and contrasting results.
Conclusions The evidence of this review suggests that all three fields, dermatoglyphics, palmar creases and digit ratio, can indicate mental disorders to varying degrees.
