Abstract:
:The purpose of this study was to evaluate the contribution of the postsynaptic mechanism to the development of motor fluctuation in advanced Parkinson's disease (PD). We used 123I-iodobenzamide single-photon emission computed tomography to measure the striatal dopamine D2 receptor densities in early levodopa-naïve PD, chronic PD with stable levodopa response, and advanced PD with fluctuating levodopa response. The basal ganglia/frontal cortex ratios at both hemispheres were calculated and averaged. PD patients with fluctuating levodopa response showed a significant decrease in striatal dopamine D2 receptor densities compared to those with early (1.57+/- 0.20 vs. 1.77 +/- 0.12, p = 0.009) or chronic stable PD (1.57 +/- 0.20 vs. 1.77 +/- 0.10, p = 0.024). We conclude that the decreased D2 receptor densities in advanced PD reduced the 'safety factor' for synaptic transmission and contributed to the development of motor fluctuation.
