What this trial studies

This study investigates the effectiveness of an app-based cognitive behavioral therapy for insomnia (CBT-I) in improving cognitive impairment among breast cancer survivors who experience insomnia. Participants will be randomly assigned to either the CBT-I intervention or an active control group receiving sleep hygiene education. The study will assess cognitive function and insomnia severity through standardized tests and follow participants for six months post-treatment. Additionally, it will explore potential changes in brain structure and inflammation related to the interventions.

Who should consider this trial

Good fit: Ideal candidates are breast cancer survivors aged 18 and older who have completed treatment within the last 1-5 years and experience insomnia and cognitive impairment.

Not a fit: Patients with other sleep disorders, neurodegenerative or psychiatric conditions, or those currently pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly enhance the quality of life for breast cancer survivors by alleviating insomnia and improving cognitive function.

How similar studies have performed: Previous studies have shown promise in using cognitive behavioral therapy for insomnia, suggesting potential success for this app-based approach.
