What this trial studies

This clinical trial investigates the effectiveness of transcranial alternating current stimulation (tACS) in patients suffering from delirium. It employs a double-blind, randomized, sham-controlled design across multiple centers, with participants receiving either active or sham treatment. The study aims to assess the safety and feasibility of tACS, measuring its impact on EEG patterns associated with delirium. Patients will undergo daily treatment for up to 14 days, with outcomes evaluated based on changes in relative delta power and delirium severity.

Who should consider this trial

Good fit: Ideal candidates are individuals over 50 years old diagnosed with delirium and exhibiting a Richmond Agitation and Sedation Scale score between -2 and +2.

Not a fit: Patients with dementia, severe cognitive impairment, or those unable to participate in delirium assessments will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the duration and severity of delirium in affected patients.

How similar studies have performed: While the use of tACS is a novel approach for treating delirium, similar studies have shown promise in improving cognitive functions in other conditions.
