Fluctuating asymmetry in patients with schizophrenia is related to hallucinations and thought disorganisation.

Fluctuating asymmetry represents the degree to which the right and left side of the body are asymmetrical, and is a sign of developmental instability. Higher levels of fluctuating asymmetry have been observed in individuals within the schizophrenia spectrum. We aimed to explore the associations of f...
