Article Synopsis
  • - This study is the first to investigate the effectiveness and safety of transcranial pulse stimulation (TPS) as a treatment for ADHD in young adolescents (ages 12-17) in Hong Kong.
  • - Conducted as a double-blind, randomized, sham-controlled trial with 30 ADHD-diagnosed participants, evaluations were made before and after TPS treatment as well as at 1 and 3-month follow-ups.
  • - Results showed that the TPS group had a consistent 30% reduction in ADHD symptoms, as measured by SNAP-IV scores, indicating that TPS is a promising and safe add-on treatment for managing ADHD.

Transcranial pulse stimulation has been proven effective to improve cognition, memory and depressive symptoms of Alzheimer's disease, but supporting evidence on other neurological diseases or neuropsychiatric disorders remains limited. This study aimed to investigate the effects of transcranial pulse stimulation on the right temporoparietal junction, which is a key node for social cognition for autism spectrum disorder, and to examine the association between transcranial pulse stimulation and executive and social functions. This double-blinded, randomized, sham-controlled trial included 32 participants (27 males), aged 12-17 years with autism spectrum disorder.

Avolition in schizophrenia has been attributed to the decoupling between emotion and motivation rather than an inability to perceive or distinguish emotions. Hence, goal-directed behavior incentivized by positive or negative reinforcement becomes impoverished and dull. It is further suggested that goal-directed actions directed at future outcomes (anticipatory or representational response) are preferentially affected, as opposed to actions directed to the current state of affairs (consummatory or evoked response).

Background: Traditional treatment alone might not effectively control the severity of attention deficit hyperactivity disorder (ADHD) symptoms. Transcranial pulse stimulation (TPS) is a non-invasive brain stimulation (NIBS) technology used on older adults with mild neurocognitive disorders and adults with major depressive disorder. However, there has been no study conducted on young adolescents with ADHD.

The prevalence of symptoms of anxiety is increasing, especially during the COVID-19 pandemic. A home use transdermal neurostimulation device might help to minimize the severity of anxiety disorder. To the best of our knowledge, there is no clinical trial using transdermal neurostimulation to treat individuals with symptoms of anxiety in Asia.

Insomnia is a common health problem in the general population. There are different ways to improve sleeping habits and quality of sleep; however, there is no clinical trial using transdermal neurostimulation to treat individuals with symptoms of insomnia in Asia. This gives us the impetus to execute the first study in Asia which aims to evaluate the efficacy of Electrical Vestibular Stimulation (VeNS) on individuals with insomnia in Hong Kong.

Article Synopsis
  • - Transcranial pulse stimulation (TPS) has shown promise in enhancing cognitive functions in Alzheimer’s patients, but its effectiveness for major depressive disorder (MDD) had not been previously tested on a wide scale until this trial.
  • - In a 2-week study with 30 participants aged 18-54, who were split into a TPS group and a waitlist control group, results indicated a significant reduction in depressive symptoms for those receiving TPS therapy as measured by the Hamilton depression rating scale-17.
  • - The findings revealed that TPS not only effectively reduced depression severity but also showed strong and lasting effects observed during a follow-up three months post-treatment.
