Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

829
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Patient-centered Care01:13

Patient-centered Care

2.9K
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Visual System01:26

Visual System

1.7K
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Drug Dosing: Obese Patients

235
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Drug Dosing: Geriatric Patients

229
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...

Visual Agnosia01:12

Visual Agnosia

1.0K
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...

Summary
This summary is machine-generated.

Visually impaired individuals exhibit altered postural stability, with peripheral vision loss increasing fall risk due to forward leaning. Postural rehabilitation may mitigate these effects.

Area of Science:

  • Ophthalmology
  • Neurology
  • Biomechanics

Background:

  • Balance relies on sensory input, including vision, to maintain stability against external stimuli.
  • Visual impairment necessitates compensatory mechanisms for maintaining balance.
  • Understanding postural adaptations in visually impaired individuals is crucial for fall prevention.

Purpose of the Study:

  • To investigate postural adaptations in individuals with age-related macular degeneration (AMD) and glaucoma.
  • To compare the postural profiles of visually impaired patients with a control group.
  • To assess the impact of visual field defects and visual acuity on postural stability.

Main Methods:

  • A prospective study involving 16 AMD patients, 17 glaucoma patients, and 18 controls.
  • Dynamic equilibrium testing using a stabilometric platform and Win-Posturo software.
  • Assessment of postural profiles under various conditions: eyes open, eyes closed, static balance, and displacement.

Main Results:

  • All groups showed improved static equilibrium with eyes open; however, visually impaired groups exhibited a greater tendency to lean forward.
  • Peripheral visual impairment was associated with a significant forward lean, increasing fall risk.
  • No significant differences in dynamic equilibrium were found between groups in initial analysis, but further conclusions suggest otherwise.

Conclusions:

  • Visual disability significantly modifies postural profiles, with peripheral vision loss leading to increased fall risk.
  • Individuals with visual impairments demonstrate more developed somatosensory mechanisms for compensation.
  • Postural rehabilitation is recommended for visually impaired patients to reduce fall risk and improve stability.
