Exploring how cognitive reserve affects non-drug treatments for cognitive impairment

Implication of Cognitive Reserve in Non-pharmacological Intervention Outcomes

Not applicable Interventional Masaryk University · NCT06563453

This study is testing how a brain stimulation treatment can help improve thinking skills in people with mild cognitive impairment and dementia, and whether having a strong cognitive reserve makes a difference in the results.

What this trial studies

This study investigates the role of cognitive reserve (CR) in the effectiveness of transcranial alternating current stimulation (tACS) for enhancing cognitive function in individuals with mild cognitive impairment and dementia with Lewy bodies. It employs advanced imaging techniques, including neuromelanin-sensitive MRI and resting-state functional MRI, to assess brain activity and connectivity. The goal is to identify which biomarkers of cognitive reserve best predict the cognitive benefits of tACS and how CR influences the brain's compensatory mechanisms during cognitive tasks. By combining dynamic and static measures of CR, the study aims to provide insights into personalized treatment approaches for cognitive decline.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals with intact cognitive performance who have been diagnosed with mild cognitive impairment with Lewy bodies.

Not a fit: Patients with advanced dementia or significant psychiatric disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective non-pharmacological interventions for patients with cognitive impairment, enhancing their cognitive function and quality of life.

How similar studies have performed: While the approach of using cognitive reserve as a predictor in tACS interventions is relatively novel, similar studies have shown promise in enhancing cognitive function through non-pharmacological methods.
