Does an increase in physiological indexes predict better cognitive performance: the PhyCog randomised cross-over...

Area of Science:

• Neuroscience
• Endocrinology
• Psychology

Background:

• Cognitive decline is a concern in type 2 diabetes (T2D).
• Both cognitive training and physical activity show potential for improving cognition.
• A psychoneurophysiological approach suggests physiological changes may influence cognitive outcomes.

Purpose of the Study:

• To examine if improved physiological indexes predict enhanced cognitive function in T2D patients.
• To compare the effectiveness of physical activity, cognitive training, and combined interventions.
• To identify the optimal intervention for preventing cognitive impairment in T2D.

Main Methods:

• A 22-week randomized controlled trial (PhyCog study) with 81 T2D patients.
• Three arms: physical activity then cognitive training, cognitive training then physical activity, or breathing exercises plus combined training.
• Assessment of cognitive performance (executive function, memory, attention) and physiological variables (allostatic load, heart rate variability, cortisol) at multiple time points.

Main Results:

• The study is designed to collect data on the relationship between physiological improvements and cognitive gains.
• Specific results are pending the completion of the trial and data analysis.

Conclusions:

• This research will elucidate the role of physiological changes in cognitive enhancement within T2D.
• Findings will inform the development of targeted interventions to mitigate cognitive impairment associated with T2D.
