まとめ
新しいオンライン認知テストであるD-Cogは、自宅でのアルツハイマー病モニタリングに有望です。このツールは認知の変化を検出し、せん妄やARIAなどの状態の早期診断を支援できます。
科学分野:
- 神経学
- 老年学
- デジタルヘルス
背景:
- アルツハイマー病(AD)の初期患者は認知の変動を経験します。
- 変化は、せん妄やアミロイド除去療法によるARIAなどの重篤な状態の兆候となる可能性があります。
- 現在のツールには、頻繁な在宅認知評価機能が欠けています。
研究 の 目的:
- 在宅での使用を目的とした新しいオンライン認知評価(D-Cog)の有用性、利便性、および実現可能性を調査すること。
- AD患者における認知の変化を検出するためのD-Cogの可能性を評価すること。
- せん妄またはARIAの早期検出ツールとしてのD-Cogを評価すること。
主な方法:
- 「認知バイタルサイン」として設計された短い(<2分)オンライン認知テストであるD-Cogを開発しました。
- MCIまたはADの患者82人からパイロットデータを収集しました。
- 6か月間の毎日の自宅でのD-Cog評価と遠隔モニタリングのために15人の参加者を募集しました。
主要な成果:
- 54人の参加者(平均年齢76歳)が研究を完了し、D-Cogの平均スコアは3.9でした。
- D-Cogスコアはミニメンタルステート検査(MMSE)スコアと高く相関していました(r=0.56、p=1.3e-5)。
- 患者はD-Cogを自宅で簡単に完了できると報告しました。
結論:
- D-Cog評価は、臨床実践およびAD患者による遠隔での在宅使用において実現可能です。
- D-Cogスコアは、従来の神経心理学的テストと良好な相関を示します。
- D-Cogは、頻繁で便利な在宅モニタリングと認知の変化の早期検出に有望です。

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...
