Temporal Interference Stimulation Treatment in Patients With Cognitive Impairment
A Randomized, Sham-Controlled Trial of Temporal Interference Stimulation Treatment in Patients With Cognitive Impairment
Source: ClinicalTrials.gov · Last updated 11 Jun 2026
Brief summary (registry, in English)
This study aims to evaluate the efficacy and safety of temporal interference stimulation (TIS), a non-invasive neuromodulation technique, in improving cognitive function in patients with cognitive impairment. TIS uses two high-frequency currents applied transcranially, which intersect within the brain to generate a low-frequency modulation field. This technique selectively modulates deep brain regions while minimizing the stimulation of superficial cortical layers. Participants will undergo individualized MRI-based modeling to determine the optimal electrode placement and stimulation parameters. The intervention consists of 10 stimulation sessions over a period of 14 days, using either active TIS or sham stimulation. Cognitive assessments, EEG recordings, and functional MRI scans will be conducted at baseline; 5 days after intervention initiation; at the end of the 10-day intervention; and during follow-up assessments at 4 weeks, 8 weeks, and 12 weeks post-intervention to evaluate both immediate and long-term effects on cognitive performance and neural activity. The study aims to determine whether TIS can serve as a feasible and effective neuromodulation strategy for individuals with cognitive impairment.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Use of medications that significantly affect cognition (e.g., anticholinergics, sedatives), unless approved by the physician.
- Presence of metal implants incompatible with MRI or TIS (e.g., pacemakers, deep brain stimulators).
- Current or recent treatment with anti-amyloid monoclonal antibodies (e.g., lecanemab, donanemab).
Other illness
- Diagnosis of other types of dementia or major neurological disorders (e.g., stroke, epilepsy, Lewy body dementia, vascular dementia, Parkinson's disease dementia, Huntington's disease).
- Major psychiatric disorders such as severe depression or anxiety.
- Severe systemic or organ dysfunction (e.g., heart failure III-IV, liver cirrhosis, renal failure).
- Severe visual or hearing impairment preventing task performance.
- History of alcohol or drug abuse.
Other
- Skull defects or cranial abnormalities.
- Inability to tolerate EEG or head stabilization.
- Participation in another clinical trial within the past 3 months.
