Dementia01:30

Dementia

562
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....

Compounds Essential to Human Function01:25

Compounds Essential to Human Function

10.1K
The human body is composed of cells that are fundamentally made up of several different molecules. These molecules are essential to carry out all physiological processes in the body and are broadly classified into organic and inorganic based on their chemical structures.
Inorganic Compounds Essential to Human Functioning
Inorganic compounds essential to human functioning include water, salts, acids, and bases. These compounds are inorganic, i.e., they do not have a carbon-hydrogen bond. Water...

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

6.3K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

The Fossil Record02:56

The Fossil Record

27.3K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

Data Reporting and Recording01:24

Data Reporting and Recording

5.4K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Types of Records I: Unit and Nurses Records

1.7K
 Unit records in healthcare settings document the patient's treatment history, including interventions, medications, diagnostic and laboratory results, progress notes, personal care needs, vital signs, and other medical information. They are crucial for managing patient care, aiding healthcare professionals in providing quality treatment and informed decision-making.
Unit records can be divided into two main types: administrative records and clinical records.
Administrative records in...

Area of Science:

  • Neurology
  • Geriatric Medicine
  • Movement Disorders

Background:

  • Essential tremor (ET) is a common neurological disorder.
  • Research suggests a correlation between ET and dementia.
  • Dementia in ET is often underestimated in clinical practice.

Observation:

  • Presents three case studies of patients with concurrent Essential Tremor and dementia.
  • Documents the progression and manifestation of comorbid dementia in ET patients.
  • Provides visual records illustrating the impact of combined conditions.

Findings:

  • Essential tremor is confirmed as a significant risk factor for developing dementia.
  • Dementia represents a critical non-motor feature of Essential Tremor.
  • The co-occurrence of ET and dementia substantially affects patient and family well-being.

Implications:

  • Highlights the need for increased clinical awareness of dementia in ET patients.
  • Emphasizes the importance of addressing non-motor symptoms in ET management.
  • Suggests potential avenues for future research into the underlying mechanisms and treatments.
