Non-invasive craniocervical lymphatic drainage to improve memory and thinking after sleep loss

Effects of Non-Invasive Superficial Craniocervical Lymphatic Drainage (NSCLD) on Memory and Cognitive Function in Adults With Sleep Deprivation: A Proof-of-Concept Study

Not applicable Interventional The George Institute · NCT07084701

This trial will try a gentle, non-invasive craniocervical lymphatic drainage technique to see if it improves memory and thinking in adults who are sleep-deprived.

What this trial studies

This proof-of-concept interventional study applies a non-invasive superficial craniocervical lymphatic drainage (NSCLD) procedure to adults experiencing sleep deprivation. Participants receive either NSCLD or a sham intervention and complete standardized memory and cognitive tests before and after treatment. The study enrolls healthy college-aged adults free of major medical or psychiatric conditions and excludes pregnant or breastfeeding individuals and those taking medications that affect cognition. Primary outcomes focus on short-term changes in attention, working memory, and executive function associated with the intervention.

Who should consider this trial

Good fit: Ideal candidates are healthy college students aged 18 or older who are currently experiencing sleep deprivation and are not pregnant, breastfeeding, or taking medications that influence memory or cognition.

Not a fit: Patients with chronic sleep disorders, uncontrolled medical conditions, prior craniocervical trauma or surgery, pregnancy or breastfeeding, or inability to complete cognitive testing are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, NSCLD could offer a quick, non-drug option to reduce short-term memory and cognitive problems caused by sleep loss.

How similar studies have performed: The approach is relatively novel in humans: preclinical and early translational work on the glymphatic system offers theoretical support, but controlled clinical evidence that lymphatic drainage improves cognition after sleep loss is limited.
