Postural sway in first-degree relatives of individuals with schizophrenia

Postural sway in first-degree relatives of individuals with schizophrenia

Abstract

Postural control deficits are well documented in schizophrenia. However, postural stability has not been assessed in first-degree relatives of individuals with schizophrenia to our knowledge. We analyzed postural sway in 27 controls (CTR) and 18 first-degree relatives (REL). The REL group was significantly impaired compared to CTR, with a larger mean sway area and longer mean sway path. These preliminary findings suggest a genetic contribution to postural control deficits observed in schizophrenia spectrum disorders. Future studies should, however, examine the contributions of shared environmental risk factors including stress, toxins, etc. to familial risk to dissociate them from shared genetic risk.
