## Abstract Subthalamic nucleus deep brain stimulation (STNβDBS) is effective in advanced Parkinson's disease (PD), but its effects on the levodopa response are unclear. We studied the levodopa response after longβterm STNβDBS, STNβDBS efficacy and predictive value of preoperative levodopa response

β¦ Synopsis
In 92 parkinsonian patients (42 men, 50 women) aged from 37-79 years (mean 62.8) the impact of cerebral atrophy as assessed by computed tomography on the course of the clinical symptomatology under levodopa during a period of 1 to 5 years was investigated. It could be shown that patients suffering from medium to severe degrees of atrophy-independent of its special location--have a less favorable response than those with normal CT findings. The data do not allow a definite decision whether cortical artrophy or ventricular enlargement are of major importance. At any rate, the width of the third ventricle seems to have no influence on the course of the clinical symptoms. After 3 years of levodopa treatment a dissociation between cerebral atrophy and therapeutic effectiveness can be observed.

Computed tomographic examinations of parkinsonian patients revealed a high incidence of cerebral atrophy, in most cases a combination of cortical atrophy and ventricular enlargement. The present study considered the relationship between cerebral atrophy and physical signs indicating or promoting art
## Abstract To further characterize the shortβterm levodopa response in early PD, we performed a retrospective analysis of the ELLDOPA study which randomized 361 early PD subjects to placebo, levodopa 150, 300, or 600 mg/day. We evaluated change in UPDRS motor scores (UPDRSm) from baseline to weeks
