研究概览
简要总结
This will be an Investigator-initiated pilot study in which participants will be assessed with various scales to measure demoralization, anxiety, depression, and subjective incompetence at baseline and every two weeks after treatment with Valbenazine for a total of 6 weeks. Improvement in TD will be assessed as well and correlated with reduction in demoralization.
详细描述
This will be an Investigator-initiated, prospective, single center, interventional pilot study. This study will examine the feasibility of a larger study aimed at determining if there is an association between the improvement in tardive dyskinesia and the reduction in demoralization and subjective incompetence in patients with tardive dyskinesia after treatment with Valbenazine. Participants in that larger study will be treated with Valbenazine for a total of 7 weeks.

研究组 & 干预措施

All participants will be treated with Valbenazine for 6 weeks.
干预措施: Valbenazine (Drug)
结局指标
主要结局
Change in demoralization Scale
时间窗: Baseline, week 2, week 4, and week 6
The change in symptoms of demoralization will be measured using the Demoralization Scale-II (DS-II). Scale scores range from 0 (minimum) to 32 (maximum), with higher scores indicating more demoralization (i.e., a worse outcome). Reduction of score to below 10 will be measured
次要结局
- Change in subjective incompetence scale (SIS) score(Baseline, week 2, week 4, and week 6)
