    Area of Science:

    • Gerontology
    • Biomedical Engineering
    • Machine Learning

    Background:

    • Increasing prevalence of depression among the elderly population.
    • Need for innovative, non-invasive methods for active depression monitoring.
    • Limitations of current depression assessment techniques in community-dwelling seniors.

    Purpose of the Study:

    • To develop and validate an approach for identifying depression in the elderly.
    • To utilize gait accelerometry data combined with machine learning for depression detection.
    • To explore the potential of gait analysis as a biomarker for geriatric depression.

    Main Methods:

    • Recruitment of 45 community-dwelling elderly individuals (22 with depression, 23 without).
    • Collection of lower back accelerometry data during a 7-meter walk at preferred speeds.
    • Feature extraction (statistical and morphological parameters) from gait acceleration phases and classification using bidirectional long short-term memory networks.

    Main Results:

    • Gait sequence features derived from accelerometry data were used as input.
    • A 4-fold cross-validation demonstrated an average classification accuracy of 0.956.
    • The machine learning model effectively distinguished between elderly individuals with and without depression.

    Conclusions:

    • Gait accelerometry combined with machine learning shows high accuracy in detecting depression in the elderly.
    • This approach offers a potential non-invasive method for self-monitoring health conditions.
    • The findings may facilitate earlier recognition of health risks and timely treatment interventions.
