Dementia01:30

Dementia

151
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual....

Radiological Investigation I: X-ray and CT

328
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

180
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Imaging Studies I: CT and MRI

384
Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

X-ray Imaging

5.7K
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Alzheimer's Disease: Overview01:26

Alzheimer's Disease: Overview

591
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Area of Science:

  • Medical Imaging
  • Neurology
  • Gerontology

Background:

  • Dementia impacts cognitive function and behavior, leading to misunderstandings.
  • Limited research exists on radiographers' dementia care.
  • Knowledgeable radiographers can reduce stigma and improve care quality.

Purpose of the Study:

  • To assess radiographers' knowledge and attitudes towards dementia.
  • To identify areas for improved dementia care education in radiography.

Main Methods:

  • An online survey of 123 registered radiographers in Ireland.
  • Utilized the Alzheimer's Disease Knowledge Scale (ADKS) and Dementia Attitudes Scale (DAS).
  • Compared scores across demographics, qualifications, and experience levels.

Main Results:

  • Knowledge scores showed no significant demographic differences (p > 0.05).
  • Attitude scores were higher for those with higher degrees (BSc, MSc) and less than 20 years' experience.
  • Knowledge and attitude showed minimal correlation (r = 0.0522, p = 0.5667).

Conclusions:

  • Attitudes towards dementia vary with age and experience.
  • Some misconceptions about dementia persist among radiographers.
  • Targeted interventions and education are needed to enhance dementia care awareness and attitudes.
