NCT05499429

Brief 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.

Study Arms (2)

active stimulus group

ACTIVE COMPARATOR

Patients were assigned into active stimulus group according to random number table

Device: Transcranial low intensity focused ultrasound stimulation

sham stimulus control group

SHAM COMPARATOR

Patients were assigned into sham stimulus control group according to random number table

Device: Transcranial low intensity focused ultrasound stimulation

Interventions

Low intensity focused transcranial ultrasound stimulation can safely and effectively regulate neuron excitability through mechanical force.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female DLB patients between the ages of 50-85;
  • The psychological evaluation was in accordance with MMSE score of 18-24 (including 18 and 24) and CDR score of 0.5.
  • Can cooperate to complete clinical research.

You may not qualify if:

  • There is a definite history of cerebrovascular stroke, and there are definite symptoms or signs of neurological deficit at the time of onset, and there are corresponding responsible lesions left by neuroimaging。
  • Those who have a history of alcoholism, or drug addiction, or neurological diseases such as brain trauma, epilepsy, encephalitis, normal intracranial pressure hydrocephalus, etc. that can cause cognitive impairment.
  • Suffering from systemic diseases that may lead to cognitive impairment (such as liver and kidney insufficiency, endocrine diseases, vitamin deficiency).
  • Have a history of using antipsychotics for more than five years before diagnosis.
  • There are contraindications for head MRI examination.
