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...

Pharmacodynamics in Geriatric Patients: Effects of Age

56
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Drug Dosing: Geriatric Patients

60
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...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

7.2K
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,...

Olfactory Receptors: Location and Structure

10.0K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

39
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...

Area of Science:

  • Gerontology
  • Neuroscience
  • Ophthalmology
  • Audiology

Background:

  • The senses are vital for interacting with the environment but are vulnerable to aging and disease.
  • Sensory decline impacts an individual's ability to navigate daily life and environmental demands.

Purpose of the Study:

  • To review the prevalence and consequences of sensory dysfunction in older adults.
  • To highlight the association between sensory deficits and cognitive/mental health outcomes.
  • To emphasize the importance of multisensory integration in aging and its clinical implications.

Main Methods:

  • A selective literature search was conducted in the Medline and Cochrane Library databases.
  • Pertinent publications on sensory function, aging, and associated comorbidities were reviewed.

Main Results:

  • Approximately 40% of individuals aged 70-79 experience dysfunction in at least one sense, with over 25% affected in multiple senses.
  • Sensory deficits are linked to increased risks of dementia (OR 1.49-2.85) and depressive symptoms (OR 3.36).
  • Multisensory integration, crucial for daily functioning, declines with age and can indicate pathological aging.

Conclusions:

  • Early detection of sensory dysfunction in the elderly is essential.
  • Interdisciplinary collaboration is needed to address sensory decline.
  • Development of sensory screening tests and multisensory integration assessments for clinical practice is recommended.
