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 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 Endocarditis01:25

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 Management01:29

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...

科学领域:

  • 神经科学是一个神经科学.
  • 认知心理学 认知心理学
  • 神经学 神经学

背景情况:

  • 亨廷顿病 (HD) 的特点是逐渐认知能力下降,早期的口头记忆缺陷在运动症状之前.
  • 敏感的认知评估工具对于了解早期的疾病病理和疾病进展至关重要.
  • 语义干扰和学习的洛文斯坦-阿塞维多尺度 (LASSI-L) 评估语义干扰,这是一个潜在受到HD影响的认知功能.

研究的目的:

  • 在亨廷顿病的不同阶段调查特定口头记忆缺陷的进展.
  • 评估LASSI-L在检测和分期HD认知变化的实用性.
  • 为了将口头记忆障碍模式与疾病持续时间和HD的严重程度相关联.

主要方法:

  • 评估了151名参与者 (89名HD患者,62名对照).
  • 参与者根据疾病出现的年数 (PIN和TMS分数) 进行了分类.
  • LASSI-L子测试 (主动语义干扰 - PSI,无法从PSI恢复 - frPSI,反向语义干扰 - RSI) 使用ANCOVA和后期测试进行分析.

主要成果:

  • 观察到口头记忆缺陷的顺序模式:PSI缺陷出现在HD表现之前>10年.
  • frPSI赤字从明显的HD出现10年后出现,随后在明显阶段出现RSI下降.
  • 98%的HD参与者表现出衰弱,其中88%的患者表现出明显的PSI -> frPSI -> RSI进展.

结论:

  • 拉西-L有效地捕捉了HD中的语义干扰缺陷的渐进性.
  • LASSI-L的性能有助于早期检测认知变化,并改进了HD疾病的病期.
  • 通过LASSI-L了解口头记忆障碍的进展,可以提高对与HD相关的认知衰退的了解.
