NCT ID NCT07174869

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 observational study tests a mobile app that uses a dynamic difficulty adjustment system to personalize cognitive activities for people with mild cognitive impairment or mild Alzheimer's disease, as well as healthy older adults. The goal is to see if the app can reach a stable difficulty level and whether that level differs between the two groups. Fifty-five participants will use the app for six weeks, and researchers will evaluate its ability to distinguish between those with and without cognitive decline.

What this could mean

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

What this could lead to
If successful, this could lead to a simple app-based tool for early detection or monitoring of cognitive decline.
What could go wrong
This is a small pilot study (55 people) focused on usability and feasibility, not on treatment or diagnosis. The app may not reliably distinguish between groups in larger, more diverse populations.
