Eredeti leírás

This pilot study aims evaluate the feasibility and initial efficacy of behavior therapy augmented by d-cycloserine (DCS) compared to behavior therapy augmented by placebo. After an initial assessment to determine eligibility, youth with TD will be randomly assigned to receive four sessions of behavior therapy augmented by either DCS or placebo. D-cycloserine is an FDA-approved antibiotic medication that has been shown to enhance extinction learning in several studies. The investigators' proof-of-concept work has found that a single session of DCS-augmented behavior therapy reduced the severity of tics targeted in treatment on the Hopkins Motor/Vocal Tic Scale (HM/VTS) compared to placebo-augmented behavior therapy. This highlights the exciting potential of combining DCS with behavior therapy to improve reductions in tic severity. However, prior to a large-scale clinical trial, it is essential to determine the feasibility and efficacy of augmenting behavior therapy with DCS over multiple treatment sessions.A teljes eredeti leírásKevesebb
