Equilibrium and Balance01:15

Equilibrium and Balance

7.9K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Pharmacodynamics in Geriatric Patients: Effects of Age

315
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

345
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

802
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

335
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism

324
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...

Area of Science:

  • Geriatrics
  • Otolaryngology
  • Neurology

Background:

  • Benign paroxysmal positional vertigo (BPPV) is the most frequent cause of vertigo in the elderly.
  • BPPV significantly impairs balance, gait, and increases fall risk in older adults, affecting independence and quality of life.
  • Aging leads to otoconia fragmentation and displacement into semicircular canals, causing vertigo with head movements.

Purpose of the Study:

  • To review the characteristics and management of BPPV in older adults.
  • To highlight the atypical presentations and increased recurrence risk in the geriatric population.
  • To emphasize the need for a multidisciplinary approach considering shared risk factors like vitamin D deficiency and osteoporosis.

Main Methods:

  • Review of clinical presentations and diagnostic tests for BPPV.
  • Discussion of treatment options, including canalith repositioning maneuvers (e.g., Epley maneuver).
  • Exploration of potential associations with geriatric conditions and systemic factors.

Main Results:

  • BPPV in older adults is often idiopathic, presents atypically, and has a higher recurrence rate.
  • Commonly prescribed medications may cause significant side effects.
  • Dix-Hallpike and Head Roll tests are effective diagnostic tools.

Conclusions:

  • Canalith repositioning can expedite symptom resolution and reduce BPPV burden.
  • Idiopathic BPPV may share risk factors with osteoporosis and vitamin D deficiency.
  • A systems-based, multidisciplinary approach is crucial for managing BPPV in older adults.
