Dermatoglyphic analysis in bipolar affective disorder and schizophrenia: ťContinuum of psychosisŤ hypothesis corroborated?

Dermatoglyphic features are thought to be indicators of events in the early embryonal stages. They might also be associated with the developmental disorders of the central nervous system (CNS) including schizophrenia. Dermatoglyphic features of 92 male patients with bipolar affective disorder (BPAD; unipolar depression and schizoaffective psychosis were excluded from the study) were compared with those of 195 males with schizophrenia (SCH) and both with those of 200 male controls (control group, CG). DSM-III-R criteria were used for the diagnostic evaluation. Quantitative analysis showed only one statistically significant difference between BPAD and SCH patient groups, regarding the c-d ridge count of the left hand. The canonical discriminant analysis permitted correct classification with only 59.23% probability between BPAD and SCH. Numerous quantitative dermatoglyphic features of both BPAD and SCH differed significantly from those of control subjects. Total finger ridge count was markedly lower in BPAD and SCH as compared to controls. These findings are not in contradiction with the hypothesis claiming that psychoses are just a set of diverse expressions (due also to noninherited factors) of a single underlying entity.
