What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is testing whether a non-invasive electrical stimulation technique can improve working memory, attention, and thinking skills in healthy older adults and those with mild cognitive impairment. The stimulation targets deep brain structures without surgery, using special electrodes on the scalp. Researchers will use MRI scans to see how the brain responds, aiming to better understand memory problems and explore potential future treatments.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
non-invasive electrical brain stimulation (transcranial temporal interference stimulation)
What this could lead to
If successful, this could point toward a new, non-invasive way to improve memory and attention in older adults with mild cognitive impairment.
What could go wrong
This is an early-stage study with only 70 participants, focused on understanding brain activity rather than proving a treatment works. The effects may be small or not translate to real-world benefits.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 70 people

The number the study aims to enrol. It can still change while the study runs.

Started

Mar 2026

Expected to finish

Jul 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

60 to 80 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * normal cognitive performance as assessed by a cognitive screening for healthy subjects * possible or probable MCI-LB or with PD-MCI, collectively called MCI-LBD, described as: presence of PD , and level II criteria for MCI (i.e. based on comprehensive neuropsychological examination), or the level II criteria for MCI , and at least two of four core DLB features including parkinsonism, visual hallucinations, attention/cognitive function fluctuation, and REM sleep behavioral disorder, or at least 1 core clinical feature and 1 indicative biomarker (probable MCI-LB). Exclusion Criteria: * Psychiatric disorders including major depression, major vascular lesions, or other brain pathologies that might present with cognitive decline.
