Summary

This cross-over pilot study aims to study the acceptability of two methods of non-invasive brain stimulation for the treatment of Parkinson's disease mild cognitive impairment (PD-MCI) - repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) targeted at the left dorsolateral prefrontal cortex (DLPFC). Twenty participants will undergo both interventions in a cross-over design. They sequentially undergo four consecutive phases (4 weeks each), 1) no-intervention baseline, 2) rTMS ór tDCS, 3) no-intervention, 4) second intervention. The primary outcome measure will be acceptability of the interventions, and secondary outcomes include feasibility, cognitive function, neuropsychiatric symptoms, motor function. We will use MRI to explore personalized targeting.

Conditions

Interventions

DEVICE

High-frequency (10Hz) rTMS

High-frequency (10 Hz) rTMS targeting the left DLPFC, based on fMRI-peak activation during performance of the Tower of London task, at 110% resting motor threshold intensity, corrected for scalp-cortex distance at the target location, for a total of 3000 pulses per session, using 30 trains of 10 seconds with 30-second inter-train intervals (total duration: 20 minutes), using neuronavigation to record the pulse location.

DEVICE

Anodal tDCS

Anodal high-definition tDCS. The anode will be placed at the F3 EEG location, coordinates registered using neuronavigation on the first intervention session on-site, and cathodes at Fp1, Fz, C3 and F7, in a ring surrounding the anode, using π cm2 circular stimulation electrodes, stimulating the left DLPFC at 2 mA intensity for a duration of 20 minutes, 15 s ramp up and 15 s ramp down. After an initial on-site instructional tDCS session, the tDCS intervention will be delivered at home, in part remotely-supervised via MS Teams.
