Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

6.0K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Visual Agnosia01:12

Visual Agnosia

203
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Diagnostic and Statistical Manual of Mental Disorders (DSM)01:27

Diagnostic and Statistical Manual of Mental Disorders (DSM)

56
The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Language and Cognition01:27

Language and Cognition

346
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Intellectual Disability01:29

Intellectual Disability

54
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

Area of Science:

  • Gerontology
  • Ophthalmology
  • Psychiatry

Background:

  • Visual impairment (VI) is a growing concern in aging populations.
  • Mental health disorders are prevalent among the elderly.
  • The relationship between VI and mental health requires further investigation.

Purpose of the Study:

  • To determine the association between visual impairment (VI) and mental disorders.
  • To analyze the impact of VI on physical, anxiety, social, and depression symptoms.
  • To investigate these associations in individuals aged 60 and above in Tehran, Iran.

Main Methods:

  • A population-based cross-sectional study involving 2789 participants aged 60+ in Tehran.
  • Multi-stage cluster sampling was employed for participant selection.
  • Visual acuity, refraction, slit-lamp biomicroscopy, and the General Health Questionnaire (GHQ) were used for assessments.

Main Results:

  • Visual impairment (VI) showed a statistically significant direct association with physical symptoms (β=0.37) and anxiety (β=0.48).
  • A borderline association was observed between VI and depression (β=0.21).
  • Total GHQ scores were significantly associated with VI (β=1.02), with physical symptoms explaining the most variance (R²=0.159).

Conclusions:

  • Visual impairment (VI) is associated with increased anxiety, depression, and physical symptoms in older adults, independent of other factors.
  • These findings underscore the need for a holistic approach to elderly care, integrating vision health with mental well-being.
  • Addressing VI is crucial for improving the overall quality of life for the aging population.
