NCT05422274

Brief Summary

This is the first nationwide study using Transcranial Pulse Stimulation to evaluate its efficacy and safety on 30 young adolescents with ADHD. Six verum/ shamTPS sessions will be delivered to all subjects on a 1: 1 ratio, balanced by gender and age. Attention deficit, hyperactivity, impulsivity, and oppositional defiance will be the primary outcome. Secondary outcomes include ADHD severity, frequency of inattention, hyperactivity, impulsivity, executive function and neural connectivity changes via neuroimaging. Results emerging from this study will generate new knowledge to ascertain whether TPS can be used as a top-on treatment in ADHD.

Outcome Measures

Primary Outcomes (1)

  • Attention deficit, hyperactivity impulse and oppositional defiance

    The Swanson, Nolan, and Pelham Rating Scale (SNAP IV) will be used to measure participants' attention deficit, hyperactivity impulse and oppositional defiance. SNAP IV consists of 26 items summarized into three factors: attention deficit, hyperactivity impulse, and oppositional defiance. Parents based on their general impressions on their children and rate the severity of symptoms on a Likert scale (0-3). Mean score \<1 indicate "normal" or "remission"; Mean score of 1 is defined as the demarcation for attention deficit and hyperactivity impulsivity; mean score \>2 indicated "abnormal". SNAP-IV is a reliable and valid scale used in RCTs and has good psychometric properties in the Chinese population.

    Changes in SNAP-IV scores from baseline at 3 months

Secondary Outcomes (4)

  • Clinical global impression

    Changes in CGI from baseline at 3 months

  • Executive function

    Changes in Stroop test from baseline at 3 months

  • The ADHD Rating Scale-IV

    Changes in ADHD RS-IV from baseline at 3 months

  • Neuroimaging

    MRI will be assessed at baseline at immediately and 2 weeks after post-stimulation

Study Arms (2)

Transcranial Pulse Stimulation (TPS group)

EXPERIMENTAL

Subjects in the TPS group will be given 6 verum TPS sessions (Pulse: 800 / session) across two weeks time, with 3 sessions per week.

Device: Transcranial Pulse Stimulation

Sham TPS Group

SHAM COMPARATOR

Subjects in the Sham TPS group will be given 6 sham TPS sessions across two weeks time, with 3 sessions per week.

Device: Transcranial Pulse Stimulation

Interventions

A total of 36 participants (both TPS group and the sham-control group) will receive six 30 minute-TPS sessions (800 pulse in each session, total: 4800 pulse) in 2 weeks' time (i.e., 3 sessions (Monday, Wednesday, Friday) per week, total: 3 hours), on a 1: 1 allocation ratio. Participants will be followed up immediately after the post-stimulation and at 1-month and 3-month period after the intervention. A 2-week TPS intervention alongside with 3-month follow-up is sufficient enough to test the effects of TPS on improving inattention and hyperactivity .
