This study shows a deep learning model can detect anxiety using brainwave data. While accurate on benchmark datasets, real-world application shows potential but requires further refinement for anxiety management.

Area of Science:

  • Neuroscience
  • Computer Science
  • Psychology

Background:

  • Anxiety disorders present a growing global mental health concern, especially where healthcare is limited.
  • Brain-computer interfaces (BCIs) offer novel avenues for mental health monitoring and intervention.
  • Electroencephalography (EEG) provides a viable biosignal for capturing neural correlates of psychological states.

Purpose of the Study:

  • To develop and validate a deep learning model for classifying anxious and non-anxious states using EEG data.
  • To assess the transferability and performance of the model on both benchmark and self-collected datasets.
  • To explore the potential integration of the system with neurofeedback for anxiety management.

Main Methods:

  • A convolutional neural network (CNN) was trained and validated on the public GAMEEMO dataset.

  • EEG data were collected from participants undergoing a custom Stroop test and a breathing exercise.
  • Domain adaptation techniques were applied to the CNN for classifying anxiety states in the self-collected dataset.

    • Main Results:

    • The CNN achieved 95.72% accuracy on the GAMEEMO dataset.
    • On the self-collected dataset, the CNN demonstrated 86.58% accuracy in classifying anxious states.
    • The study highlighted a performance difference between benchmark and real-world data, indicating a need for further model optimization.

    Conclusions:

    • The developed automated system shows promise for detecting stress-induced anxious states using EEG and deep learning.
    • Proof-of-concept transferability was demonstrated, though a performance gap exists for real-world applications.
    • The findings support the future integration of this system with neurofeedback for anxiety management strategies.
