Overview

Transcranial pulse stimulation (TPS) is a newly developed non-invasive brain stimulation (NIBS) technique from Austria \& Germany with highly promising applicability in neuropsychiatric disorders. Clinical trials have shown a beneficial effect of TPS in patients with Alzheimer\'s disease and depression. Although TPS has the capability to noninvasively target deeper brain regions such as the dorsal anterior cingulate cortex (dACC) and anterior insula cortex (AIC), no TPS study has been conducted to investigate the feasibility and effectiveness of dACC or AIC stimulation. Here, a randomized, single-blind, sham-controlled clinical pilot trial is proposed to probe the effects of TPS over bilateral dACC and AIC on modulating cognitive, behavioral and emotional functions and functional connectivity of brain circuits.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
