abstract = {BackgroundMotor response to dopaminergic therapy is a
characteristic of patients with Parkinson's disease (PD).
Whether nondopaminergic neurotransmitters contribute to
treatment response is uncertain.ObjectivesThe aim of this
study is to determine whether putaminal y-aminobutyric acid
(GABA) levels are associated with dopaminergic motor
response.MethodsWe assessed putaminal GABA levels in 19 PD
patients and 13 healthy controls (HCs) utilizing ultra-high
field proton magnetic resonance spectroscopy. Motor
performance was evaluated using the Movement Disorder
Society—Unified Parkinson's Disease Rating Scale, Part
III, in the ON and OFF states. Statistical analysis
comprised group comparisons, correlation analysis, and
multiple linear regression.ResultsIn PD, GABA levels were
significantly higher compared to HCs (1.50 ± 0.26 mM
vs. 1.26 ± 0.31 mM, P = 0.022). Furthermore, GABA
levels were independent predictors of absolute and relative
dopaminergic treatment response.ConclusionsOur findings
indicate that elevated putaminal GABA levels are associated
with worse dopaminergic response in PD, emphasizing the
essential role of nondopaminergic neurotransmitters in motor
response. © 2021 The Authors. Movement Disorders published
