Low-intensity TUS for Sleep Disturbances in Patients With Chronic Tinnitus

Background: Tinnitus, as a common symptom, can jeopardize the sleep quality and brain function and even lead to hearing loss and cognitive decline in elderly patients. The co-occurring tinnitus and sleep disturbances can significantly affect the cognitive functions and quality of life, and even be implicated as a key contributing factor in the development of prodromal dementia. At present, very few non-pharmacological therapies are developed for managing these comorbidities in elderly patients. Focused low-intensity transcranial ultrasound stimulation (TUS) enables to stimulation the deep brain structures, such as hippocampus, with optimized focality and specific frequency. Objectives: We aim to 1) investigate the safety, feasibility and efficacy of a 2-week focused low-intensity TUS on the severity of tinnitus and sleep disturbances in elderly patients; 2) determine the sample size of a full-scale randomized clinical trial of low-intensity TUS in patients with tinnitus; 3) evaluate the effects of low-intensity TUS on the severity of tinnitus, sleep quality and cognitive functions at 2, 4 and 6 weeks after the treatments. Design: A 2-week randomized, double-blind, controlled clinical trial. Methods: Chinese right-handed tinnitus patients with sleep disturbances (aged from 60 to 90 years) will be randomly assigned to a 2-week intervention of either low intensity TUS or sham TUS, with 7 participants per arm. Before intervention, T1-weighted magnetic resonance imaging (MRI) an…
