Derealization symptoms according to the subjective visual vertical during unilateral centrifugation in patients with type 2 diabetes mellitus.

Background: A recent study has shown variability on the perception of verticality during unilateral centrifugation among patients with type 2 diabetes mellitus; it is yet unknown if it is related to symptoms of unreality.

Objective: In patients with type 2 diabetes mellitus compared to age matched healthy volunteers, to assess depersonalization/derealization (DD) symptoms before and after unilateral centrifugation, according to the subjective visual vertical (SVV).

Methods: 47 patients with type 2 diabetes mellitus and 50 age matched healthy volunteers participated in the study.
