Dermatoglyphics in patients with schizophrenia*

چکیده
BACKGROUND There are controversial evidences on the association between fingerprint traits and schizophrenia. We compared fingerprint traits of patients with schizophrenia and normal individuals in Iranian population. METHODS Finger tip dermal ridge of 290 patients with schizophrenia and 290 normal subjects were studied for four dermal traits. Data was analyzed with Pearson correlation and student's tests. RESULTS Finger print patterns and secondary creases were not significantly different between the two groups (p > 0.05). Although mean ridge counts of left and right index fingers of the case group were greater than the control group (p < 0.05), these differences were not significant in females. CONCLUSIONS Probably the left index ridge counts and fluctuating asymmetry in schizophrenic patients are different from those of the normal population. This difference may serve as a diagnostic biological marker for screening people susceptible to schizophrenia. Further studies are needed to determine predictive value of fingerprint trait as a biomarker for the schizophrenia.

Dermatoglyphics as markers of prenatal disturbances in schizophrenia: a case-control study
Aim: Several studies have reported the importance of dermatoglyphics as markers of a prenatal disturbance in patients with schizophrenia. Due to the fact that fingerand handprints are formed by the end of the second trimester, they may provide clues to disturbances in early development. The aim of this study was to determine specific dermatoglyphical frequencies in a sample of patients with sch...
متن کاملPalmar Dermatoglyphics in Schizophrenia
Palm prints of 55 male and 33 female schizophrenic patients from Assam Medical College, Dibrugarh were examined for a possible association between palmar dermatoglyphic characteristics and the disease. There was a marked difference between patients and normal controls with regard to palmar C line termination, axial triadic, number of ridges at the a-b inter digital area and the frequency of var...
متن کاملDermatoglyphics and Schizophrenia: a meta-analysis and investigation of the impact of obstetric complications upon a-b ridge count.
BACKGROUND Patients with schizophrenia show deviances in their dermatoglyphics, in particular reductions in palmar a-b ridge counts (ABRCs), which are evidence of an early developmental deviance. However, the severity or the origin of these ABRC changes has not been established. METHOD (i) We examined the published literature on the ABRC in patients with schizophrenia against controls with a ...
متن کاملAlopecia Areata and Dermatoglyphics
Objective: To study of relationship between alopecia areata and finger print dermatoglyphic types in 100 patients with alopecia areata and in 100 controls. Methods: A case control analytical study was done on fingerprints of patients with alopecia areata. The control cases were older than 50 years old without any history of alopecia areata. Dermatoglyphical trials of total fingers were al...
متن کاملNeurodevelopmental interactions conferring risk for schizophrenia: a study of dermatoglyphic markers in patients and relatives.
Schizophrenia is hypothesized to be the result of an interaction between specific genetic factors and nonspecific insults during embryonic development. Dermatoglyphic abnormalities appear to mark these putative insults--providing information about the temporal sequence of aberrant developmental events as well as the organism's vulnerability to their adverse effects. In the present study, dermat...
متن کاملDermatoglyphics in Female Catatonic Schizophrenics
Dermatoglyphjc features of 50 ICD-9 diagnosed female catatonic schizophrenic patients in the age range of 15-60 years were compared with those ethnically matched controls of the same sex. Patients were found to differ from controls in qualitative as well as quantitative features. Most of the differences matched well with the previous studies.
