ABSTRACT

The study of dermal ridges in schizophrenia has been extensive, but only recently has fluctuating asymmetry been described. This study relates dermatoglyphic patterns with the specific positive and nega- tive symptoms of the disease in 72 DSM-III-R defined schizophre- nia and 72 normal unrelated ethnically matched controls. Schizo- phrenic subjects had significant lower ridge counts in both hands. Fluctuating asymmetry in the a-b ridge counts was significantly lower in schizophrenic subjects (0.50 vs 0.70, p‹0.05). The positive and negative symptom scale (PANSS) was used to determine symptom severity. Schizophrenics with predominantly negative symptoms showed significantly lower counts and higher fluctuating asymmetry than schizophrenics with positive symptoms. Our study showed findings congruent with the hypothesis that schizophrenia could be related to central nervous system develop- mental abnormalities.
