まとめ
ウェブベースの認知評価であるcCOGは、認知症のリスクがある個人の認知機能の遠隔モニタリングにおいて、良好なテスト再テスト信頼性を示しています。これは、大規模な疾患サーベイランスでの使用をサポートします。
科学分野:
- 神経科学; 心理測定学; デジタルヘルス
背景:
- ウェブベースの認知評価は、遠隔疾患モニタリングに不可欠です。; 軽度認知障害(MCI)および認知症には、正確かつタイムリーな検出が必要です。; テスト再テスト信頼性は、認知評価における重要な心理測定学的特性です。
研究 の 目的:
- cCOG評価のテスト再テスト信頼性を評価すること。; 認知症のリスクがある集団における遠隔認知評価のためのcCOGの適合性を判断すること。
主な方法:
- 認知症のリスクがある250人の参加者が、ベースライン時および1か月後にcCOGを遠隔で完了しました。; 5つのサブテストからグローバル認知スコア(GCS)が計算されました。; 相関級内相関係数(ICC)を使用してテスト再テスト信頼性を評価しました。; デバイスタイプ、年齢、性別、教育によって分析を層別化しました。
主要な成果:
- 完了率が高い(ベースラインで94.8%、1か月後に94.0%)。; GCSのテスト再テスト信頼性が良好で、ICCは0.75でした。; さまざまな人口統計学的サブグループやデバイスタイプで同等の信頼性。
結論:
- cCOGは、認知症のリスクがある集団における遠隔認知評価において信頼性の高いパフォーマンスを示しています。; この調査結果は、cCOGを大規模モニタリングおよび認知機能低下の早期検出に使用することを支持しています。; さらなる研究では、遠隔設定におけるテスト完了および外れ値に影響を与える要因を調査する必要があります。

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...

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 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...
