「CADi2」は認知症早期発見のための検査アプリです。Cognitive Assessment for Dementia, iOS versionの頭文字をとりCADiです。住民健診等におけるマススクリーニングでの使用を想定しています。CADi2ではCADiから2つの問題の入れ替え及び問題順序の変更を実施し,認知症検出精度を向上させています。 ※重要:CADi2は認知症の可能性のある方を検出するのが目的であり、この検査における低得点が直ちに認知症を意味するものではありません。同様に高得点が認知症でないことを確証するものでもありません。結果に不安がある場合は、かかりつけ医等にご相談ください。 【主な機能】 認知症早期発見のための一次スクリーニング用検査です。 ◆CADi検査項目の構成 本検査は10個の項目で構成されます。 1.即時再認、2.長期記憶、3.逆唱、4.見当識(月)、5.見当識(曜日)、6.計算、7.直方体回転、8.順列作成A、9.順列作成B、10.遅延再認。 1項目1得点の10点満点で評価されます。また、各設問を回答するのにかかった時間も記録されます。 ◆必須装置 CADiは音声で問題が提示されるため、ヘッドフォンを必要とします。ヘッドフォンは密閉型が推奨されます。検査者の声が聞こえなくなるため、ノイズキャンセラーのついたヘッドフォンの使用は避けてください。 ◆使用条件 CADiは検査者と被験者が一対一で行うことを想定しています。事前に内容を把握した検査者が被験者につき、被験者を補助してください。答えを教える以外の補助(分かりやすく言い直してあげる等)は問題ありません。被験者が単独でこの検査を行った場合、その結果はあまり信頼できるものではありません。 ◆検査の流れ 検査は個人識別のためのID入力、ヘッドフォン装着、タッチ練習、練習問題2問、本問題10問、フィードバックの順に行います。音声と画面の指示に従ってください。 ◆評価 10点満点中6点以下が認知症を疑いますが、これは暫定的な基準です。 ◆データ管理 検査データはメールに添付して送信する方法と、iTunesに接続して取り出す方法が用意されています。また、iTunesからsqlite3形式のデータベースファイルが見えるようになって 【その他の機能】 ◆玉ころがしゲーム 認知機能維持のためのアプリとして、玉ころがしゲームが付属しています。非常に簡単な面から若者でも難しい面まで、全部で30面あります。このゲームもクリアするまでの時間等が記録されます。ご自由に活用ください。 【データの取扱】 検査データはクラウドに送信され保存されます。このデータは本アプリの検査性能の向上と機能開発ために活用され、それ以外の用途では利用されません。また、検査データは個人情報を含みません。 【開発と検証】 CADiシリーズは,島根大学医学部神経内科が株式会社テクノプロジェクト[http://www.tpj.co.jp]及び株式会社イーストバック[http://www.eastback.co.jp]の協力を得て開発を行いました。妥当性の検証は島根大学医学部付属病院においてアルツハイマー病患者を対象に行われました。CADi2は健常者とアルツハイマー病患者を感度0.85~0.96,特異度0.81~0.93の精度で識別可能でした(Onoda & Yamaguchi, 2014) [http://www.ncbi.nlm.nih.gov/pubmed/25310860]。すでに島根県内の幾つかの自治体における住民健診や,全国複数の脳ドック施設において認知症早期発見のため活用がなされています。 本アプリの機能は以下の研究成果に基づいて設計されています。 - 認知症マススクリーニングにおける iPad の活用:CADi の開発と検証 https://www.jstage.jst.go.jp/article/hbfr/34/3/34_331/_article/-char/ja/ - Revision of the Cognitive Assessment for Dementia, iPad Version (CADi2) https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0109931 - やる気スコアを用いた脳卒中後の意欲低下の評価 https://www.jstage.jst.go.jp/article/jstroke1979/20/3/20_3_318/_article/-char/ja

Want to improve your performance in sports and eSports? Just 3 minutes a day can improve your dynamic vision with simple eye training exercises. Recommended not only for athletes, but also for students, professionals, and anyone concerned about eye fatigue or aging vision. TRAIN YOUR EYES – GAIN THE EDGE Dynamic vision is the key to success. It determines how quickly and smoothly your eyes can follow moving targets — essential in ball sports like baseball, soccer (football), and tennis, in martial arts that require instant reactions, and in eSports where split-second decisions decide victory. Dynamic vision depends on the extraocular muscles that move your eyes. Just like body muscles, they can be strengthened at any age through consistent practice. This app acts as your personal eye trainer, helping you strengthen eye movement, reaction speed, and focus. ◆ Exercises Included • Teleportation – Train your eyes to track suddenly appearing objects • Peripheral Vision – Expand your field of view and peripheral awareness • Zigzag – Eye movement and diagonal tracking (DVA) • Tile – Vertical and horizontal tracking (DVA) • 3D – Kinetic visual acuity training (3D/KVA) • Flash Memory Test – Improve focus, instantaneous vision, and short-term memory • MOT Skills ◀NEW (Pro) – Advanced multi-object tracking to improve focus and reaction speed Speed control is available — from extra-slow for beginners to ultra-fast for experts. ◆ User Voices - “My reaction time in games improved a lot.” – Apex player, Japan - “Perfect warm-up before sports practice.” – MtMan820, USA - “Helps my eyes relax after long hours of screen work.” – Dirkalirk, USA - “So much content for free. Great for daily basics.” – Tsurutontan37, Japan ◆ Pro Features Free to start. Unlock full training power with Pro: • MOT Skills – Master multi-object tracking • Full Speed Control – From ultra-fast to extra-slow with custom settings • Change Ball Colors (3D Mode) • Remove All Ads – Train with zero distractions • Family Sharing – One purchase covers your whole family Free trial included — experience all Pro features before subscribing. ◆ Start Today Consistent training won’t show instant results like muscle workouts, but progress is guaranteed if you keep going. Improving dynamic vision and reaction speed is the skill that separates winners from losers. Use it as a warm-up before matches, for martial arts and ball games, or as an Aim Trainer for FPS games. It’s also helpful for improving focus for those who find it hard to concentrate (including ADHD tendencies). Your personal eye trainer helps you build stronger vision habits – just 3 minutes a day to stay sharp and focused, and ahead.
