Official title

A Pilot Randomized Placebo-Controlled Trial of Transcranial Pulse Stimulation (TPS) in Early Alzheimer's Disease (AD) Subjects

Overview

TPS is a non-invasive therapeutic modality that uses focused, low-energy pulse stimulation to stimulate tissue regeneration and reduce inflammation. In the context of neurological disorders, it is hypothesized that TPS can modulate neuronal activity, enhance synaptic plasticity, and reduce neuroinflammation. It is a relatively new application in neurological disease treatment and is still under intense investigation.

Detailed description

This pilot randomized placebo-controlled trial investigates the effects of transcranial pulse stimulation in subjects with early Alzheimer's Disease (AD). The TPS/Sham-TPS is administered for the first two weeks, followed by additional sessions at some week intervals. The transcranial pulse stimulation device used in this trial is a CE-certified medical instrument (ISO 9001 and ISO 13485).

The study aims to evaluate cognitive function, and neuropsychiatric symptoms using the some cognitive assessment tools, Frontal near-infrared spectroscopy (fNIRS), and fasting blood test at baseline at week 12.

This study is expected to lay the groundwork for future, larger-scale studies

Interventions

  • Device transcranial pulse stimulation (TPS)
    The TPS/Sham-TPS therapy is administered for the first two weeks, followed by additional sessions at some week intervals.
  • Device transcranial pulse stimulation (TPS-Sham)
    Participants will undergo an identical procedure using a device that mimics the sound and sensation of active TPS but delivers no therapeutic energy pulses to the brain.

Primary outcome measures

  • Change in Alzheimer's Disease Assessment Scale-Cognitive Subscale score. [Time frame: baseline( 1st Week); follow-up ( after finishing the TPS therapy at 12th week)]
Secondary outcome measures (5)
  • Change in the Neuropsychiatric Inventory total score. [Time frame: baseline( 1st Week); follow-up ( after finishing the TPS therapy at 12th week)]
  • Change in the Animal Fluency Test score [Time frame: baseline( 1st Week); follow-up ( after finishing the TPS therapy at 12th week)]
  • Change in the Disability Assessment for Dementia total score. [Time frame: baseline( 1st Week); follow-up ( after finishing the TPS therapy at 12th week)]
  • Change in oxygenated hemoglobin (HbO) and deoxygenated hemoglobin (HbR) in the cerebral blood [Time frame: baseline( 1st Week); follow-up ( after finishing the TPS therapy at 12th week)]
  • Change in plasma Aβ42/40 [Time frame: baseline( 1st Week); follow-up ( after finishing the TPS therapy at 12th week)]
