Selective head cooling intervention improves mental health markers: A multimodal feasibility study

Area of Science:

• Neuroscience
• Psychophysiology
• Mental Health Research

Background:

• Selective head cooling is increasingly studied for psychophysiological symptom relief.
• Prior research indicates benefits after traumatic brain injury, but effects on mental health in unaffected individuals are less known.

Purpose of the Study:

• To investigate the effects of a one-week head cooling intervention on cognitive function, mental health, and electroencephalography (EEG) patterns.
• To compare these outcomes against a control group in individuals without traumatic brain injury.

Main Methods:

• A one-week head cooling intervention was implemented.
• Cognitive function, mental health status, and EEG patterns were assessed pre-intervention, acutely post-intervention, and longitudinally.
• Comparisons were made between the head cooling group and a control group.

Main Results:

• The head cooling group showed a significantly greater change in relative alpha EEG power post-intervention compared to controls (p=0.004).
• Both groups experienced reduced depression, but the head cooling group demonstrated significantly greater symptom relief (p=0.020).
• Exploratory analysis suggested trends in EEG changes related to pre-existing anxiety.

Conclusions:

• Selective head cooling shows preliminary efficacy in reducing depression symptoms.
• The intervention may promote brain activity related to relaxation, particularly in individuals with anxiety disorders.
• Head cooling significantly modulated EEG signals after repeated treatment, warranting further investigation.
