- Brief Summary
Some evaluations such as MDS-UPDRS Part III (OFF), MDS-UPDRS Part IV, and UDysRS showed improvement in symptoms, but in terms of exercise in daily life, the score was lower at 3 months after surgery compared to the evaluation at screening. Decrease, then increase was confirmed, and it was found that the symptoms gradually returned. There was no change in the average dose of L-dopa. Adverse events were confirmed as serious adverse events, but none were attributable to the conduct of the study.
