Depression: Overview

222
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

Area of Science:

  • Artificial Intelligence in Healthcare
  • Computational Psychiatry
  • Speech Signal Processing

Background:

  • Psychological assessment is crucial for mental health diagnosis and treatment but faces overwhelming demand.
  • National health systems struggle to meet the growing need for mental health evaluations.
  • Automated tools are needed to expedite the diagnosis process and improve accessibility.

Purpose of the Study:

  • To develop and evaluate an AI-powered tool for automated psychological assessment using speech signals.
  • To leverage a Siamese neural network (SNN) for classifying depression and assessing its severity from speech.
  • To provide interpretable predictions that aid medical experts in mental health evaluations.

Main Methods:

  • Utilized a Siamese neural network (SNN) architecture for analyzing standardized speech representations.
  • Employed a framework capable of multiple downstream tasks from a single latent representation.
  • Conducted extensive experiments on a publicly available dataset following a standardized protocol.

Main Results:

  • The SNN-based framework significantly outperformed the state-of-the-art in classifying speech depression.
  • The system demonstrated high accuracy in assessing the severity of depression from speech.
  • The AI tool provides interpretable predictions, facilitating interaction with medical professionals.

Conclusions:

  • AI-powered speech analysis using SNNs offers a promising solution for mental health assessment.
  • The developed tool can effectively diagnose depression and its severity, addressing service demands.
  • Interoperable and interpretable AI predictions can enhance clinical decision-making in mental healthcare.
