Repetitive transcranial magnetic stimulation for hypokinetic dysarthria in Parkinson’s disease

Takeaway

  • Low-frequency repetitive transcranial magnetic stimulation (rTMS) of the right superior temporal gyrus (STG) improves vocal articulation in Parkinson’s disease (PD) patients with hypokinetic dysarthria (HD).

Why this matters

  • Non-invasive rTMS is being evaluated as a therapy for various PD symptoms, including HD; however, the efficacy of this treatment has not been established and an optimal stimulation target has not been identified.
