Clinical and psychometric correlates of dopamine D2 binding in depression.
BACKGROUND: Single photon emission tomography (SPET) with the dopamine D2/3 ligand 123I-IBZM gives a semi-quantitative estimate of dopamine binding. In depressed patients, we predicted evidence of reduced function, i.e. increased binding, particularly in more retarded patients. METHODS: Fifteen depressed patients with major depressive illness and 15 healthy, age- and sex- matched volunteerS were examined with a clinical and neuropsychological test battery and high resolution IBZM-SPET.
