The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

2.9K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Larynx01:21

Larynx

2.5K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Bone Disorders01:29

Bone Disorders

4.3K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption01:22

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

29
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

27
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

Menopause01:28

Menopause

2.4K
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Summary

Older adults over 80 with presbyphonia showed significantly greater vocal deviations in pitch, roughness, and breathiness compared to younger groups. This highlights age-specific vocal aging impacts needing tailored interventions.

Area of Science:

  • Gerontology
  • Speech and Language Pathology
  • Acoustic Analysis

Background:

  • Vocal aging, or presbyphonia, affects older adults.
  • Understanding age-related vocal changes is crucial for effective intervention.

Purpose of the Study:

  • To investigate vocal differences in older adults diagnosed with presbyphonia across three age groups (60-70, 71-80, 81-90).

Main Methods:

  • Acoustic and auditory-perceptual analysis of voice recordings from 60 older adults (60-90 years) with presbyphonia.
  • Statistical comparison of vocal parameters across age groups.

Main Results:

  • Older adults over 80 exhibited significantly higher deviations in dysphonia grade, roughness, breathiness, and pitch.
  • Increased jitter, shimmer, vocal breaks, and GNE measures were observed in the 81-90 age group, with some nearing abnormal levels.

Conclusions:

  • Vocal aging significantly impacts acoustic and perceptual features, particularly in adults over 80.
  • Age-specific vocal characteristics must be considered in evaluating vocal aging and developing interventions to mitigate vocal decline.
