Transcranial Magnetic Stimulation for Alzheimer's Disease Treatment
Intervention Based on Transcranial Magnetic Stimulation for Alzheimer's Disease Patients: Randomized Clinical Trial
Source: ClinicalTrials.gov · Last updated 21 Jul 2026
Brief summary (registry, in English)
Background: Alzheimer's disease is a major health problem in our society. To date, pharmacological treatments to reduce Alzheimer's disease symptoms have obtained poor results and there is a growing interest in finding non-pharmacological treatments for this impactful disease. Transcranial Magnetic Stimulation is a non-invasive tool which can induce changes in brain activity and long term modifications of impaired neural networks, and therefore holds promise as a clinical intervention. Our overall goal is to study the benefit of targeting Transcranial Magnetic Stimulation based on the individual's unique functional connectivity (personalized targeting) instead of current non-individualized approaches. Specifically, the intermittent Theta Burst protocol will be used and changes in cognitive, functional, and emotional deficits in these patients will be evaluated. Functional brain connectivity changes induced by the TMS treatment will be also assessed. Methods: A double blind randomized controlled trial will be conducted to assess the effects of TMS treatment immediately, one month, three months and six months after the end of the treatment in comparison to the baseline measurements. Forty-five patients with a diagnosis of Alzheimer's disease, will be randomly allocated (1:1:1) into experimental (active Transcranial Magnetic Stimulation), sham control group, or conventional intervention control group. Neuropsychological, functional, and emotional assessment will be conducted, as well as functional connectivity measures, in order to assess the effectiveness of the treatment. Discussion: The investigators expect to demonstrate that personalized Transcranial Magnetic Stimulation intervention has measurable positive impact in cognitive and emotional functioning, functionality, and brain connectivity, thus representing a potential treatment for Alzheimer's disease.

Other illness
- Not controlled medical conditions or severe mental disorders that may affect the Central Nervous System, including signs of increased intracranial pressure or intracranial lesions
- Medical conditions not controlled that may cause medical emergencies in case the produce convulsions (expel: cardiac malformations, cardiac arrhythmias, asthma, etc.)

Who the study is looking for
- Diagnosis of Alzheimer's disease according to the diagnostic criteria of the National Institute on Ageing and the Alzheimer's Association
- Ages between 60 and 75 years
