概括
数字认知测试,即基于平板电脑的认知评估工具 (TabCAT),对早期发病的阿尔茨海默病 (EOAD) 的早期检测充满希望. TabCAT测量与传统测试相关,并识别阿尔茨海默病的生物标志物,如粉样蛋白和蛋白PET.
科学领域:
- 神经科学是一个神经科学.
- 老年学是一门学科.
- 数字健康数字健康
背景情况:
- 早期发病的阿尔茨海默氏症 (EOAD) 由于年轻,症状多样化和进展迅速,因此存在诊断挑战.
- 数字认知评估为早期EOAD检测提供了传统测试的可扩展替代方案.
- 基于UCSF平板电脑的认知评估工具 (TabCAT) 与临床和生物标志物数据进行了评估.
研究的目的:
- 评估TabCAT认知测试与传统神经心理测试的有效性.
- 根据粉样β (Aβ) PET状态来确定TabCAT在区分阿尔茨海默病 (AD) 患者的能力.
- 在EOAD患者中调查TabCAT性能和tau PET成像之间的关联.
主要方法:
- TabCAT (执行功能/注意力和视觉空间测试) 给了83名对照组和392名EOAD患者.
- 使用排序系数分析TabCAT和纸笔测试之间的相关性.
- 用于评估Aβ-PET阳性歧视的接收器操作特征 (ROC) 分析.
- 在Voxel-wise分析中,研究了Aβ阳性患者的TabCAT得分和tau PET之间的关联.
主要成果:
- TabCAT执行功能测试 (匹配,侧翼) 与已建立的认知测试 (MMSE,MoCA,Trails A) 有着强烈的相关性.
- 视觉空间TabCAT测试 (线长,线向) 与视觉空间任务 (本森图片复制,轨道A) 相相关.
- 匹配测试最好地区分了Aβ阳性和Aβ阴性患者 (AUC=0.82),表现优于MMSE和MoCA.
- TabCAT执行功能测试与皮层区域的tau PET相关;视觉空间测试与尾的tau PET相关.
结论:
- TabCAT 证明了与传统的认知评估具有良好的并发有效性.

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 (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 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 (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...

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...
