Depression: Overview

Depression: Overview

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,...

Long-term Depression

Long-term Depression

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.

Drug Dosing: Geriatric Patients

Drug Dosing: Geriatric Patients

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Geriatric Psychiatry
Public Health
Psychometric Evaluation

Background:

Depressive disorders affect 13-25% of India's elderly population.
The World Health Organization (WHO)-five Well-being Index (1998 version) is a simple screening tool.
Evaluating its Indian version is crucial for identifying depression in the elderly Indian community.

Purpose of the Study:

Determine depression prevalence in rural elderly in Udupi district, Karnataka, India.
Assess the validity and reliability of the WHO-five Well-being Index (1998 version) for screening depression in this population.

Main Methods:

A cross-sectional study conducted over eight months in Udupi district, India.
627 individuals aged 60+ were sampled using probability proportionate to size (PPS).
The WHO-five Well-being Index (1998 version) was validated against the ICD-10 depression inventory.

Main Results:

The prevalence of depression was 21.7% (95% CI = 18.4 - 24.9).
The Indian version demonstrated high sensitivity (97.0%), specificity (86.4%), and overall accuracy (0.89).
Kappa statistics confirmed significant reliability (k = 0.71).

Conclusions:

The Indian version of the WHO-five Well-being Index (1998 version) is an effective screening tool.
This instrument aids in identifying depression within the elderly Indian community.
The study supports its use for geriatric mental health assessments in India.
