Brain wave‑guided noninvasive brain stimulation to help working memory in dementia
Official title: Brain Wave Informed Non-invasive Brain Stimulation: Improving Neural Networks of Working Memory in Dementia: a Proof-of-concept Study
Run by McMaster University · NCT07673770 · Data updated 2026-11-12
This study tests whether synchronizing brain waves with EEG‑guided transcranial magnetic stimulation can improve working memory in people with dementia or Alzheimer's disease.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults 55 and older with Alzheimer's disease or related dementias, able to communicate in English, and with sufficient cognitive function to complete testing.
✕Probably not a fit
Participants who do not show improvement in working memory or who have contraindications to TMS may not benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Researchers will use EEG to monitor brain waves related to working memory and apply time‑matched, noninvasive TMS to try to restore their alignment. The approach is tailored to each person’s brain patterns and aims to enhance short‑term memory and everyday thinking abilities. It is a proof‑of‑concept study to explore feasibility, safety, and potential signals of benefit in this population.
Why it matters
Potential benefit: If successful, participants might experience improved working memory and greater independence in daily activities.
How similar studies have gone: Previous studies with brain stimulation for memory have shown mixed results, and this EEG‑triggered approach is relatively novel and exploratory.

Inclusion Criteria: * Individuals must be diagnosed with Alzheimer's Disease or related dementias by a clinician. * Individuals must exhibit adequate oral communication skills and cognitive function sufficient to obtain a score above 10 on the MMSE * Instructions will be delivered in English; therefore participants must demonstrate an understanding of instruction provided in English. * Individuals must be at least 55 years or older Exclusion Criteria: * Contraindications to TMS; presence of a pacemaker, metal/electrical/magnetic implants not including titanium, known history of untreated or uncontrolled psychological disorders, pregnancy, history of seizure or diagnoses of epilepsy, are taking any prescription medications that increase the risk of seizure. * Allergy to rubbing alcohol, which is needed to prepare electromyography for TMS
