Clinical Trial Summary

A randomized controlled clinical study was conducted in the xuanwu hospital Single Center of Capital Medical University to preliminarily explore the efficacy and safety of transcranial focused low-intensity ultrasound stimulation in the treatment of dementia with Lewy bodies in the early stage, to clarify the effective mechanism and form an effective clinical treatment plan.


Clinical Trial Description

This project plans to recruit 20 patients with mild Lewy body dementia.They were randomly divided into transcranial focused low-intensity ultrasound active stimulation group and sham stimulation group. Patients receive treatment three days a week, and the daily treatment time is 20-30 minutes.The duration of treatment is 4-12 weeks. Before treatment, cognitive assessment, resting EEG, head MRI and PET examination of glucose metabolism were completed.Complete the overall cognitive assessment, resting EEG and MRI examination within one week after the treatment, and complete the overall cognitive assessment and PET examination of glucose metabolism at the follow-up 6 months after the treatment.Fill in the treatment side effect scale and adverse event form.Keep the original oral drug dosage unchanged during the treatment process. ;
