Could a single session ease brain fog? new study investigates
NCT ID NCT07379723
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a single clinic visit with a special attention exercise can help people with Functional Cognitive Disorder (FCD), a condition causing memory and thinking problems without a clear physical cause. About 30 adults aged 65 or younger will try the intervention and complete questionnaires to see if it reduces symptoms and improves daily life. The goal is to find out if this brief approach is practical and helpful enough to study further.
