Depression: Overview

395
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,...

Depressive Disorders: MDD and Dysthymia

231
Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...

Long-term Depression

2.7K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

    Area of Science:

    • Neuroscience
    • Computer Science
    • Artificial Intelligence

    Background:

    • Depression recognition remains a challenge, often relying on single data sources.
    • Multimodal approaches offer a more comprehensive understanding of depression.
    • Historical Chinese poetry from the Song Dynasty alluded to multimodal perspectives.

    Purpose of the Study:

    • To develop and validate a computer-aided depression recognition framework using decision-level multimodal fusion.
    • To enhance the accuracy and objectivity of depression diagnosis.
    • To explore the potential of multimodal data in understanding depression.

    Main Methods:

    • Extracted linear and nonlinear electroencephalography (EEG) features using an adaptive auto-regression (AR) model.
    • Selected EEG and graph metric features from depression-related brain regions for fusion.
    • Implemented a decision-level multimodal fusion model based on multi-agent cooperation theory.
    • Utilized data from 24 depressed patients and 29 healthy controls (HC).

    Main Results:

    • The decision-level multimodal fusion method significantly outperformed single modal and independent classifiers in depression recognition.
    • Achieved a highest accuracy rate of 92.13% for depression recognition.
    • Demonstrated that multimodal fusion captures more comprehensive information about depression.

    Conclusions:

    • Decision-level multimodal fusion is a powerful tool for accurate depression recognition.
    • Improving information processing in specific brain regions may aid depression treatment.
    • No single classifier is universally optimal for all classification tasks.
