Outcome Measures

Primary Outcomes (1)

  • Change in Magnetoencephalography (MEG) Connectivity Measures

    Our MEG outcome will be a change in small-worldness, global efficiency, nodal efficiency and degree distribution pre-TMS to immediately post-TMS treatment.

    2 weeks

Secondary Outcomes (1)

  • Post-TMS Change From Baseline in Cognitive Scores

    2 weeks

Study Arms (2)

Real TMS

EXPERIMENTAL

TMS will be administered using a 70-mm diameter air-cooled figure-of-8 coil and SuperRapid2 Magstim Stimulator. Repetitive pulses will be delivered to the right and left pre-frontal cortex (Brodmann area 46) using a frameless stereotactic navigation system and the subject's magnetic resonance imaging (MRI) in Brainsight software. Stimuli will be delivered at 20 Hz at 90% resting motor threshold (rMT) for 25 trains of 30 pulses per train, inter-train interval of 30 seconds for a total of 750 pulses per hemisphere. This dose and duration of repetitive TMS (rTMS) is based on physiological studies of healthy adults and treatment studies of cognition in PD and Alzheimer's disease.52, 123 Side of first stimulation (left vs right hemisphere) will be counterbalanced across subjects.

Device: Real TMS

Sham TMS

SHAM COMPARATOR

Sham stimulation will be delivered using a sham coil fitted with electrodes to mimic both the auditory and somatic sensation of real TMS.

Eligibility Criteria

Age40 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of probable PD (using United Kingdom Brain Bank criteria)
  • Diagnosis of mild cognitive impairment
  • No unstable medical condition

You may not qualify if:

  • Features suggestive of other causes of Parkinsonism or other neurological disorders
  • Prior deep brain stimulation (DBS) or ablation surgery
  • Evidence for active depression or Hospital Anxiety and Depression Scale (HADS) score greater than or equal to 11
  • Motor symptoms expected to interfere with scanning (e.g. sever tremor)
  • Contraindications to TMS, MEG, or MRI such as pregnancy, pacemaker, unstable cardiac disease, skull lesion, claustrophobia, history of epilepsy, or on medications known to lower seizure threshold
  • Implanted electronic devices or metal

Limitations and Caveats

Our specialized MEG data analyst working on the Primary outcome has encountered a Covid-related family emergency, which has delayed the analysis process.
