Chronic Kidney Disease II: Clinical Manifestations01:24

Chronic Kidney Disease II: Clinical Manifestations

520
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Coronary Artery Disease III: Clinical Manifestations01:30

Coronary Artery Disease III: Clinical Manifestations

299
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Endocarditis II: Clinical Features of Infective Endocarditis

364
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Heart Failure III: Clinical Manifestations01:26

Heart Failure III: Clinical Manifestations

436
Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

Gastroesophageal Reflux Disease II: Clinical Features and Management

652
Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.
Clinical Manifestations
GERD presents itself in a multitude of ways, with symptoms varying from person to person. The hallmark symptoms are...

Hypertension III: Clinical Manifestations and Diagnostic Studies01:30

Hypertension III: Clinical Manifestations and Diagnostic Studies

437
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Gerontology

Background:

  • The verb fluency task is a challenging verbal assessment.
  • It shows potential for early diagnosis of Mild Cognitive Impairment (MCI) and dementia.

Purpose of the Study:

  • To conduct a scoping review of studies assessing the verb fluency task in individuals with MCI and dementia.
  • To analyze the methodology, performance patterns, and diagnostic capabilities of the verb fluency task.

Main Methods:

  • Scoping review following PRISMA-ScR guidelines.
  • Searched PubMed, LILACS, Scielo, Embase, and Scopus for relevant studies.
  • Included studies measuring verb fluency in MCI or dementia populations.

Main Results:

  • 16 studies were included in the review.
  • Verb fluency task performance was significantly lower in individuals with dementia compared to MCI and healthy controls.
  • Deficits correlate with impaired working memory, executive functions, and temporal lobe dysfunction.

Conclusions:

  • The verb fluency task is a sensitive tool for differentiating MCI from dementia.
  • It effectively highlights underlying cognitive deficits.
  • Future research should focus on qualitative and longitudinal analyses.
