Magnetic brain zaps tailored to each patient may boost memory in Alzheimer's

First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time
Summary
This study investigates whether transcranial magnetic stimulation (TMS) — a non-invasive technique that uses magnetic pulses to stimulate brain areas — can improve thinking, mood, and daily function in people with Alzheimer's disease. Unlike standard TMS, this approach personalizes the stimulation targets based on each person's unique brain connectivity. The trial involves 45 participants aged 60–75 with mild Alzheimer's, who will receive either active TMS, a sham (placebo) treatment, or a conventional non-personalized TMS over two weeks. Researchers will track changes in cognition, mood, and brain activity for up to six months after treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- personalized transcranial magnetic stimulation (TMS) using intermittent theta burst stimulation (iTBS)
- What this could lead to
- If successful, this approach could offer a non-drug treatment to slow cognitive decline and improve mood in Alzheimer's disease.
- What could go wrong
- This is a small, early-stage trial with only 45 participants, so results may not apply broadly. The benefits may be modest or temporary.

Inclusion Criteria: * 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 * Mini Mental State Examination score between 20 and 26 * Global Deterioration Scale score of 3 or 4 * Functional independence for basic daily life activities (part C of the Blessed Scale equal or 0) * Rosen Ischemia Scale less or equal to 4 * Able to read and write * Stable medical and pharmacological state during the 3 consecutive months immediately before the start of the study * Computed Tomography Scan and Magnetic Resonance Imaging in the last 12 months previous to the selection, compatible with the diagnosis of probable Alzheimer's disease in the subjects diagnosed * Absence of clinically significant anomalies in the medical history or clinical laboratory results during the selection * Screening analyses within normal range with the objective of detecting and excluding other causes of dementia in the last 12 months previous to selection. Laboratory values required in order to be considered within the normal range are as follows: complete blood count, thyroid hormones, T4, folic acid, vitamin B12, albumin, transaminase alanine, amino-transferase aspartate, gamma-glutamic transferase, sodium, potassium, urea, creatinine, glucose while fasting * Being treated by Acetylcholinesterase Inhibitors * Signed consent form, previously approved by the Research Ethics Committee Exclusion Criteria: * Knowledge of Spanish or Catalan after the age of 15 * Less than 4 years of schooling * Intellectual deficiency (Premorbid Intelligence Quotient, vocabulary, less than 85) * Not controlled medical conditions or severe mental disorders that may affect the Central Nervous System, including signs of increased intracranial pressure or intracranial lesions * Presenting one or more vascular risks * Medical conditions not controlled that may cause medical emergencies in case the produce convulsions (expel: cardiac malformations, cardiac arrhythmias, asthma, etc.) * Medical history of convulsions, previous diagnosis of epilepsy, previous registry of abnormal electroencephalogram or family history of epilepsy * Severe hearing problems or ringing in the ears (tinnitus) * Severe loss of visual acuity * Moderate or severe depression according to a score \>11 (moderate depression) or 19 (severe depression) in the Geriatric Depression Scale * Presence of tremors or motor control of the dominant upper extremity * Being under pharmacological treatment with medications indicated in the security guidelines. * Drug or alcohol consumption or history of abuse in the last 24 months prior to the study * Implants of metal pieces in the brain (excluding dental fillings) * Either of the following medical devices: pacemaker, implanted medication pumps, vagal nerve stimulators, deep cerebral stimulators, transcutaneous electrical stimulation units, ventriculus-peritoneal derivations, titanium plates, cochlear implants, aneurysm clips, etc… * Negative response towards new technology * Existence of any situation that may cause the subject, according to the principal researcher, not be an adequate candidate for the study
