In Alzheimer’s disease (AD), executive function, abstract thinking, and reasoning decrease from the onset; therefore, top-down processing in visual perception may also decrease. This study aimed to examine the association between the cognition of incomplete line drawings and frontal lobe function in early-stage AD patients. The study participants were eight early-stage AD patients and 11 healthy elderly controls. The cognitive task involved incomplete line drawing, which was created by deleting 65% of a line drawing,   and then the subject were asked to name the drawn object. To examine the relevance of top-down processing in visual cognition, the Frontal Assessment Battery (FAB) was performed. The cognition of incomplete line drawing was significantly reduced in the AD group compared with that in the healthy control group. The correlation between incomplete line drawing cognitive results and the FAB score was 0.52; however, it did not reach significance. These results indicate that the visual perception of incomplete line drawing decreases in AD, most likely due to a decrease in the top-down processing of visual information.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"対象の視覚認知においては，ボトムアップ処理とトップダウン処理が存在する．アルツハイマー病患者（Alzheimer’s disease; AD）では初期から実行機能，抽象的思考，推論が低下するため，視覚認知におけるトップダウン処理が低下する可能性がある．本研究の目的は，初期AD 患者における不完全線画の認知の特徴と，前頭葉機能との関連性を検討することである．対象は初期AD 患者8 名，対照群は健常高齢者11 名であった．方法は線画の線分を65％消去した不完全線画の認知課題を作成し，描かれている物品名を呼称してもらった．視覚認知におけるトップダウン処理との関連性を見るため前頭葉簡易知能検査FAB を実施した．その結果，不完全線画の認知がAD 群は健常高齢群より有意に低下した．不完全線画の認知成績とFAB 成績との相関は0.52 であったが，有意水準に達しなかった．以上から，AD では不完全線画の視覚認知が低下し，その背景には視覚情報のトップダウン処理機能の低下があると考えられた．","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国際医療福祉大学学会"}]},"item_10001_radio_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_radio_item":"publisher"}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID（NCID）","attribute_value_mlt":[{"subitem_source_identifier":"AA12537130","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"21863652","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"北原, 崇真"},{"creatorName":"キタハラ, タカマサ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤田, 郁代"},{"creatorName":"フジタ, イクヨ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-03-22"}],"displaytype":"simple","filename":"22_1(29-36p).pdf","filesize":[{"value":"577.5 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"本文(PDF)","url":"https://iuhw.repo.nii.ac.jp/record/801/files/22_1(29-36p).pdf"},"version_id":"1eab0b15-85eb-450f-bae4-1e8cf3df5b7b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"アルツハイマー病","subitem_subject_scheme":"Other"},{"subitem_subject":"視覚認知","subitem_subject_scheme":"Other"},{"subitem_subject":"線画認知","subitem_subject_scheme":"Other"},{"subitem_subject":"トップダウン処理","subitem_subject_scheme":"Other"},{"subitem_subject":"Alzheimer’s disease","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"visual persection","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"line drawing perception","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"top down processing","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"アルツハイマー病における不完全線画の視覚認知","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"アルツハイマー病における不完全線画の視覚認知"},{"subitem_title":"Visual perception of incomplete line drawings in Alzheimer’s disease","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"15","path":["134"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-03-22"},"publish_date":"2017-03-22","publish_status":"0","recid":"801","relation_version_is_last":true,"title":["アルツハイマー病における不完全線画の視覚認知"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-06-21T10:41:58.683578+00:00"}
