The Effect of TPS on Cognitive Functions in Older Adults With MCI
Sponsor: The University of Hong Kong
Summary
The goal of this randomized controlled trial is to learn if Transcranial Pulse Stimulation (TPS) can improve cognitive functions in older adults with mild cognitive impairment (MCI). The study will also assess the safety of TPS. The main questions it aims to answer is: Does TPS improve cognitive functions such as global cognition, attention, memory, and executive function? Researchers will compare TPS to a sham control to evaluate the efficacy and safety of TPS in improving cognitive functions in older adults with MCI. Participants will: Be randomly assigned to receive either TPS or a sham intervention Undergo 6 sessions of TPS or sham intervention over a 2-week period Visit the clinic for cognitive assessments at 4 different time points (baseline, immediately post-intervention, 1-month follow-up, and 3-month follow-up) Complete questionnaires and undergo standardized neurocognitive tests, and/or MRI scans, and/or EEG assessments The study aims to provide insights into the potential therapeutic role of TPS in enhancing cognitive functions among older adults with mild cognitive impairment.

Interventions
transcranial pulse stimulation
Participants in the experimental arm will receive six sessions of Transcranial Pulse Stimulation (TPS) over a two-week period, using the NEUROLITH® TPS system (Storz Medical AG, Switzerland). Each session will involve delivering 6,000 ultrasound pulses at an energy level of 0.2-0.25 mJ/mm² and a frequency of 4-5 Hz, targeting specified brain regions based on MRI navigation.
Sham TMS
Participants in the sham control group will undergo six sessions over a two-week period, utilizing the same NEUROLITH® TPS system (Storz Medical AG, Switzerland) as used in the experimental group. The key difference lies in the standoff device attached to the handpiece: while the experimental arm uses a standoff filled with silicone oil to transmit ultrasound pulses, the sham group\'s standoff is filled with air. This design ensures that the sham device replicates the appearance, feel, and sound of the active treatment without transmitting any therapeutic pulses, effectively maintaining the blinding aspect of the study.
