Effect of Deep Transcranial Magnetic Stimulation (dTMS) on Cognition in Older Adults With Subjective Cognitive Decline (SCD)

Intervention Type: Device, Other
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY

Deep transcranial magnetic stimulation (dTMS) is a brain stimulation technique that involves generating a brief magnetic field in a coil that is placed on the scalp. The magnetic field passes through the skull and induces a weak electrical current in the brain that briefly activates neural circuits at the stimulation site. The Brainsway dTMS H7-Coil is able to target an area of the brain that has been shown in studies to be linked to greater resilience to cognitive decline. In this study, the investigators will combine dTMS with cognitive training in older adults with subjective cognitive decline (SCD) and examine the effect of this treatment on memory, other cognitive abilities, and mood. In addition, the investigators will examine the combined effects of dTMS and cognitive training on brain activity as measured using electroencephalography (EEG). Approximately 30 older adults from ages 55 to 70 with SCD and a positive family history of Alzheimer's disease will be enrolled in this study.

Participants
Target number of participants: 30
Treatments
Experimental: 20 sessions of dTMS and Cognitive Training
Participants will receive dTMS followed by computerized cognitive training.~dTMS: The motor threshold (MT) will be measured by delivering single stimulations to the motor cortex with gradually increased intensity. After defining the MT, the coil will be positioned anterior to the hot spot using the ruler on the participant's cap, and a dTMS session will be performed with the dosing of the stimulus intensity titrated slowly to approximately 120% of the motor threshold. On Day 1 of the treatment, stimulation will be delivered at an intensity ranging from 80% to 100% of the participant's MT depending on their initial tolerance to the stimulation. Stimulation intensity will then be slowly titrated by sequentially increasing the intensity by 10% over the remaining days of the first week until a maximum intensity of 120% of MT is achieved depending on the tolerability of the patient.~Immediately following dTMS, participants will complete 20-30 minutes of cognitive training.
Sham_comparator: 20 sessions of sham/control stimulation and Cognitive Training
Participants will receive sham intervention followed by computerized cognitive training.~The sham intervention consists of treatment with similar technical parameters which induce scalp sensations but do not penetrate into the brain.~Immediately following dTMS, participants will complete 20-30 minutes of cognitive training.
