The association between the Lie scale of the Maudsley personality inventory and striatal dopamine D-2/D-3 receptor availability of healthy Chinese community subjects

The present study examined the relationship between the Lie scale scores and striatal D-2/D-3 receptor availability with respect to the cerebellum in 42 healthy community Volunteers in Taiwan using single photon emission computed tomography (SPECT) with [I-123]iodobenzoaminde (IBZM). Even after controlling of age and educational level, subjects' Lie scale scores of the Maudsley personality inventory correlate negatively with D-2/D-3 receptor availability. Individual with higher Lie scale scores may have higher impulsivity due to lower dopaminergic availability. (c) 2005 Elsevier SAS. All rights reserved.
