What this trial studies

This study investigates the effects of combined anodal transcranial direct current stimulation (tDCS) and cognitive training on decision-making and impulse control in healthy volunteers aged 18 to 40. Participants will undergo either active or sham tDCS while performing the Iowa Gambling Task, which assesses decision-making under uncertainty. The study aims to determine if the combined intervention leads to more advantageous decisions and better impulse control compared to the sham treatment. Additionally, the research will explore whether these effects can be generalized to other cognitive tasks related to motor impulsivity.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy volunteers aged between 18 and 40.

Not a fit: Patients with epilepsy, neurological conditions, significant head injuries, or a history of substance misuse or major mental disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance decision-making and impulse control, potentially benefiting individuals with impulsivity-related issues.

How similar studies have performed: While there is limited research on the combined effects of tDCS and cognitive training, similar studies have shown promise in enhancing cognitive functions.
