Официальное название

Targeted Therapeutic Transcranial Focused Ultrasound Intervention for Alcohol Use Disorder

Обзор

This study explores the potential of transcranial ultrasound stimulation (TUS) as an innovative therapeutic approach for individuals with Alcohol Use Disorder. By targeting specific brain regions associated with compulsive behaviors and reward dysfunction, the researchers aim to assess the safety and efficacy of TUS in reducing symptoms and enhancing cognitive flexibility.

Подробное описание

Alcohol Use Disorder (AUD) is a prevalent and highly debilitating condition characterized by compulsive alcohol consumption, loss of control over drinking behavior, and significant impairment in social functioning and quality of life. Estimates suggest that the economic burden of AUD is substantial, with alcohol-related harm costing the UK over £21 billion per year (Public Health England, 2016). There is a pressing need for novel interventions that surpass current treatment approaches in both effectiveness and comprehensiveness, addressing the neural and behavioral mechanisms underlying AUD. Low-intensity transcranial focused ultrasound stimulation (TUS) is an emerging non-invasive brain stimulation technique with the potential to modulate neural activity with high spatial precision.

The neural basis of AUD involves dysfunction across several brain regions, including the prefrontal cortex (impaired executive control: Koob \& Volkow, 2016), the striatum (habit formation and reinforcement: Everitt \& Robbins, 2016), the amygdala (heightened stress reactivity: Koob, 2021), and the thalamus (altered sensory and reward processing: Müller-Oehring et al., 2015). TUS can precisely modulate neuronal activity in both cortical and subcortical regions, making it a promising tool for targeting the disrupted neurocircuitry of AUD. This study aims to explore the safety and efficacy of TUS in modulating key brain regions involved in compulsive alcohol use and cognitive control, with the goal of reducing AUD-related symptoms and improving treatment outcomes.

Вмешательства

Устройство low intensity transcranial focused ultrasound stimulation (TUS)
Low-intensity transcranial focused ultrasound (TUS) provides an energy source with millimeter resolution that can be focused anywhere in the brain safely and effectively for non-invasive and transient neuromodulation. TUS is an important advance and of great significance for brain-mapping efforts, diagnostics, and therapies in neuroscience and particularly promising for addiction therapy as it provides unprecedented non-surgical access to the brain regardless of depth. Low intensities of focused

History:

serious head trauma or brain surgery
(first-degree relatives with) epilepsy, convulsion, or seizure
diagnosis of a neurological or psychiatric disorder (other than AUD)
adverse reactions to non-invasive brain stimulation

medication that will interfere with the study or constitutes an increased risk of adverse effects (e.g., affects brain excitability)
hearing problems or ringing in the ears
skin diseases or sensitivity at intended TUS stimulation site
Any significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the trial, or may influence the result of the trial, or the participant's ability to participate in the trial.
