“…The most commonly studied dermatoglyphic indices include finger and palmar ridge counts, palmar atd-angle, ridge patterns on the fingertips, and palmar flexion crease patterns (PFCs). Unusual and atypical dermatoglyphic ridge patterns are often associated with mental disorders such as schizophrenia [ 5 ]. This is unsurprising, given the involvement of the nervous system in the timing and development of dermal ridge patterns [ 6 ].…”

Dermatoglyphics, ridge constellations on the hands and feet, are permanently formed by the second trimester of pregnancy. Consequently, they are considered “fossilized” evidence of a specific prenatal period. A high frequency of dermatoglyphic anomalies, or a high rate of dermatoglyphic asymmetry (discordance), is an indication of developmental instability (prenatal disturbances) prior to 24-week gestation. Most dermatoglyphic studies in psychiatry focus on adult schizophrenia. Studies on dermatoglyphic deviances and autism are sparse, include severely disturbed and intellectually retarded patients with autism, and are carried out mainly in non-Western European populations. In this study, finger print patterns, atd-angles, and palmar flexion crease patterns (PFCs) are compared between Western European adolescent teenage males, of average intellect, with Autism Spectrum Disorders (ASD; n = 46) and typically developing adolescent teenage males (TD; n = 49). Boys with ASD had a higher rate of discordance in their finger print patterns than TD boys. Thus, the hypothesized prenatal disturbances that play a role in the etiology of schizophrenia and severe autism might not be specific to these severe psychiatric disorders but might also be involved in the etiology of varying degrees of ASD.

“…It has been found that the most frequently mentioned in articles statistically significant indicators were total finger ridge score and the palmar ridge score on the line connecting the tri-radii a-b [12]. A similar study was conducted by a group of Bulgarian researchers, who also point to the priority importance of the index of the palmar ridge score on the line connecting the tri-radii a-b in this disease [3].…”

According to modern scientific literature, specific dermatoglyphic signs can be diagnostic markers of a person’s mental state. The purpose of the work is to identify the association of dermatoglyphic indicators with personality characteristics of practically healthy men of Ukraine. From the data bank of the materials of the research center of National Pirogov Memorial Medical University, Vinnytsya were taken the primary dermatoglyphic and questionnaires indicators of personality characteristics of 92 practically healthy men in the third generation residents of Vinnitsya, Khmelnytsky, part of Ternopil and Zhytomyr regions. Processing of dermatoglyphs was performed according to the method of Cummins H. and Midlo Ch. (1961) in the statement by Gladkova T.D. (1966). For objective evaluation of personality traits of practically healthy men, a number of leading indicators were determined, which included a number of properties of temperament (according to Eysenck), anxiety (according to Spielberger), accentuated personality traits (according to Shmishek), motivational orientation of personality (by Rotter), as well as the peculiarities of psycho-emotional organization of personality, aggressiveness, the level of distribution of asthenic and depressive personality manifestations (by the color test of Luscher), which were determined on the basis of personal use personality questionnaires and test methods. Factor analysis was performed in the “Statistica 6.1” license package. The main factors that indicate the association of personality traits of practically healthy men with some dermatoglyphic indicators are identified: “ridge count of fingers” (dispersion ratio – 13.22%) and “the magnitude of the angle atd” (dispersion ratio – 10.66%). Analysis of the obtained relationships of the interdependence of indicators of personality characteristics with dermatoglyphic indicators showed that with increasing indicators of ridge counts of the fingers and the delta index the degree of probability of growth of indicators of neuroticism according to Eysenck, situational and personal anxiety according to Spielberger, the accentuation of the character of the emotional and arousing types by Shmishek, subjective control in the field of health and illness according to Rotter, black and gray color by Luscher decreases, and the indicators of the accentuation of the character of the anxious and demonstrative types by Shmishek, the overall internality of the level of subjective control in the field of educational (professional) relations according to Rotter, blue and blue-green color by Luscher – is increasing. As the magnitude of the angle atd increases on both hands, the degree of likelihood of growth of neuroticism according to Eysenck, situational and personal anxiety according to Spielberger, accentuation of the character of the emotional, anxious and arousing types by Shmishek, blue color by Luscher increase, and indicators of accentuation of the character of the demonstrative type according to Shmishek, the general internality of the level of subjective control, in the field of educational (professional) relations and in the field of health and illness according to Rotter, blue-green, black and gray color according to Luscher – decrease. The use of factor analysis has allowed to determine the most significant correlation of indicators of personality characteristics with dermatoglyphic indicators.

“…Currently available literature about palmistry and its scientific application are a result of scientific analysis performed on the palm contours of diseased patients. [14][15][16] In 2011, a study published in International Journal of Morphology associated the chromosomal aberration with pattern of simian and Sydney lines or life line and head line. 4 In support, similar observation with context to palm creases has been made in current study where palmists reported that palms having branching of heart line on the mount of Venus indicate brain disease or brain hemorrhage.…”

Background The past three decades have seen palmistry as an interface to human health. There have been no previously organized attempts in utilizing this knowledge to predict the state of disease. Objective Due to unavailability of any biological marker for diagnosing amyotrophic lateral sclerosis (ALS) till date, we attempt to examine whether palmistry could be used for detecting the onset and survival of patient suffering from ALS. Methods Patients suffering from ALS attending the neurology outpatient department at Postgraduate Institute of Medical Education and Research, India were selected for study. Palm photographs were obtained from all patients including controls after their consent. Patients suffering from other comorbidities such as diabetes, hypertension, migraine, as well as smokers and nonsmokers were included in the study. Twenty-six ALS patients, 30 neurological controls, and 34 healthy age matched controls were recruited in the study. Retrospective analysis of the palm pictures based on blinding method was performed by academically qualified palmists. Results The results demonstrated the need for further studies in the subject even though the observations made were independent by both the palmists. Conclusion This study opens new vistas for cheiromancy to be further explored for analysis in larger samples.

Dermatoglyphics – a Possible Biomarker in the Neurodevelopmental Model for the Origin of Mental Disorders

Abstract: The contradictory data in the literature on dermatoglyphics in mental disorders suggest the need for further studies on these biological markers in order to identify their place in the neurodevelopmental etiological model of these diseases.
