    Area of Science:

    • Neuroscience
    • Gerontology

    Background:

    • The aging process affects multiple body systems, with the nervous system undergoing significant alterations.
    • Understanding these changes is crucial for diagnosing and managing age-related neurological conditions.

    Purpose of the Study:

    • To provide a comprehensive review of the effects of aging on the human nervous system.
    • To discuss functional, behavioral, physiological, and pathological changes associated with aging.
    • To explore the relationship between sensory processes and neurological examination in older adults.

    Main Methods:

    • Literature review synthesizing existing research on neurobiology of aging.
    • Analysis of functional and behavioral changes in the aging nervous system.
    • Discussion of pathological changes and specific neurological disorders.

    Main Results:

    • Aging is associated with slowed reaction times and altered cognitive functions.
    • Physiological changes in the brain include alterations in structure and neurotransmitter systems.
    • Pathological changes can lead to conditions such as Alzheimer's disease and normal pressure hydrocephalus.

    Conclusions:

    • Aging induces a complex array of changes in the nervous system, impacting cognition and behavior.
    • Neurological examination and sensory process assessment are vital for identifying age-related neurological deficits.
    • Further research is needed to understand and mitigate the progression of age-related neurological diseases.
