Altered States of Awareness01:06

Altered States of Awareness

156
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Alzheimer's Disease: Overview01:26

Alzheimer's Disease: Overview

451
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...

Theoretical Approaches to Psychological Disorder01:29

Theoretical Approaches to Psychological Disorder

117
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...

Assessment of the Gastrointestinal System I: Subjective Data

152
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health History
The initial step in assessing the GI system is obtaining a comprehensive health history. This includes inquiring about the patient's history or presence of problems...

Area of Science:

  • Neurology
  • Emergency Medicine

Background:

  • Acute encephalopathy is a frequent emergency room presentation.
  • Evaluation is complicated by patient's condition and broad differential diagnoses.
  • Identifying rare neurologic causes is crucial for timely treatment.

Purpose of the Study:

  • To discuss the differential diagnosis of acute encephalopathy.
  • To present an approach to patient evaluation.
  • To provide a diagnostic framework for altered mental status.

Main Methods:

  • Review of differential diagnoses for acute encephalopathy.
  • Literature review on neurodiagnostic testing yield.
  • Development of a structured diagnostic approach.

Main Results:

  • Encephalopathy evaluation presents diagnostic challenges.
  • Systemic causes are common, but neurologic causes can be life-threatening.
  • A systematic approach improves diagnostic accuracy.

Conclusions:

  • A structured diagnostic framework is essential for evaluating acute encephalopathy.
  • Timely identification of neurologic causes improves patient outcomes.
  • This approach aids clinicians in managing patients with altered mental status.
