Altered neural processes underlying executive function in occupational burnout-Basis for a novel EEG biomarker

Area of Science:

• Neuroscience
• Psychology
• Occupational Health

Background:

• Occupational burnout is a global concern, necessitating better understanding of its effects on brain function.
• Previous research indicated executive function (EF) challenges and altered cardiac physiology in burnout.
• This study investigates the impact of burnout on brain physiology during EF tasks.

Purpose of the Study:

• To examine the neural underpinnings of executive function deficits in individuals experiencing occupational burnout.
• To identify potential electrophysiological biomarkers for burnout detection.
• To correlate brain activity patterns with burnout severity and daily life executive function challenges.

Main Methods:

• Fifty-four volunteers completed burnout, depression, and EF inventories.
• Participants performed a Go/NoGo task while undergoing electroencephalography (EEG) recording.
• Event-related potentials (ERPs), specifically N2 and P3 components, were analyzed.

Main Results:

• Burnout group reported higher depression and daily life EF difficulties.
• No significant differences in objective task performance were observed between groups.
• Burnout group exhibited increased centroparietal P3 amplitude and prolonged N2-P3 interpeak latency (IPL) during the Go condition.
• ERP measures significantly correlated with burnout symptoms and predicted burnout severity and metacognition index.

Conclusions:

• Occupational burnout is associated with distinct alterations in brain physiology during executive function tasks.
• Increased P3 amplitude and prolonged N2-P3 IPL suggest compensatory neural resource allocation and slowed cognitive transitions.
• Electrophysiological measures show potential as objective biomarkers for burnout, aiding in its early and accurate detection.
