What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

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.

Summary

This study investigates how Alzheimer's disease and frontotemporal dementia alter a person's sense of self and ability to understand others. Researchers will compare patients with healthy older adults using questionnaires and brain imaging. The goal is to link changes in self-awareness and social cognition to specific brain changes, shedding light on the personality shifts common in dementia.

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 research could help explain why people with dementia experience personality changes, potentially guiding future therapies.
What could go wrong
This is an observational study with only 40 participants, so findings may not apply to all dementia patients. It aims to understand, not treat, the condition.

This is an AI summary of the original study and may miss details. Read our disclaimer.

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

40 people

The number who actually took part.

Started

Mar 2013

Finished

Mar 2021

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

45 to 85 years

Sex

Anyone

Healthy volunteers

Accepted

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