Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 12–60 with narcolepsy type 1 confirmed by PSG/MSLT, with Epworth Sleepiness Scale >12, and no contraindications to MRI or electrical stimulation.

Probably not a fit

Patients with other causes of daytime sleepiness, significant comorbidities, pregnancy, or contraindications to MRI/electrical stimulation may not benefit.

What this trial studies

This randomized, double-blind study tests a theta-burst temporal interference protocol aimed at modulating deep brain activity in the hypothalamus for narcolepsy type 1. Participants receive active or sham TI stimulation and are evaluated for changes in daytime sleepiness and related symptoms. The study includes individuals aged 12 to 60 who meet diagnostic criteria and have moderate daytime sleepiness, with safety monitoring for MRI and stimulation-related risks. Results from this trial may indicate whether TI stimulation is a feasible treatment approach for NT1.

Why it matters

Potential benefit: If successful, TI stimulation could offer a noninvasive option to improve daytime sleepiness and related symptoms in NT1.

How similar studies have gone: Previous research has explored noninvasive brain stimulation for sleep disorders, with mixed but promising signals for deep-brain targeting.
