Chronic Kidney Disease II: Clinical Manifestations01:24

Chronic Kidney Disease II: Clinical Manifestations

516
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

295
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

358
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

430
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

647
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

433
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.
  • 认知科学 认知科学
  • 神经学 神经学

背景情况:

  • 帕金森病 (PD) 经常涉及诊断前的认知症状.
  • 认知训练 (CT) 显示了增强工作记忆等认知功能的潜力.
  • 将CT与神经调节相结合,例如跨直流刺激 (tDCS),是PD认知障碍的新兴治疗策略.

研究的目的:

  • 研究结合认知训练 (CT) 与跨直流刺激 (tDCS) 的疗效,以改善帕金森病 (PD) 患者的认知功能.
  • 为了评估道tDCS针对左背侧前额叶皮质的影响,当与认知训练任务配对时.
  • 评估经过联合干预的PD患者在工作记忆,注意力,情绪和整体认知方面的变化.

主要方法:

  • 20名被诊断患有PD的个人 (年龄在50-80岁,没有痴呆症) 被随机分为活跃的tDCS或安慰剂组.
  • 两组都接受了结合tDCS的认知训练 (在5次会议中30分钟2mA),目标是左侧脊侧前额叶皮质.
  • 使用分类工作记忆跨度任务 (CWMS) 来测量工作记忆和注意力的改善,进行干预前后的评估.

主要成果:

  • 初步数据显示,在CWMS任务中,回忆 (p=0.030) 和敲击 (p=0.038) 的表现有统计学上显著的改善.
  • 无论参与者是否接受活性tDCS或安慰剂,都观察到这些改善.
  • 没有发现情绪或更广泛的神经心理认知指标的显著变化.

结论:

  • 认知训练和tDCS的结合显示出增强帕金森病患者特定工作记忆任务的潜力.
  • 这些发现表明,CT,可能被tDCS增强,可能有助于减轻PD的认知缺陷.
  • 需要对更大的队列进行进一步的研究,以确认这些初步结果并探索其全部治疗潜力.
