聴覚情報処理障害（APD）を疑う4症例に対する評価—標準注意検査（CAT）を含めた多角的評価

Evaluation of four cases of suspected auditory processing disorder:Multifaceted evaluation including standard attention examination

　聴覚情報処理障害（APD）疑い4症例に対して多角的評価を行い，聴覚情報処理検査（APT）と注意，記憶，発達，精神の各側面の特徴を明らかにすることを目的として研究を行った．対象は，一般的な聴力検査を行ったが異常を認めず，聞こえにくさのチェックシートにて109点未満であった4例とした．評価は，APT，標準注意検査法（CAT），標準言語性対連合学習検査（S-PA），Reyの複雑図形検査（ROCFT），SALAの無意味語の復唱，AQ日本語版，CAARS^TM日本語版，日本語版自己評価式抑うつ性尺度（SDS）を施行した．4症例のなかには，APTの結果に短期記憶，分配性・転換性注意，持続性注意が関係した症例，精神的疲労や多動性/落ち着きのなさが関係した症例とさまざま存在した．多角的評価を行うことで，個々のAPD症状の影響因子が明らかになった．

　The purpose of this study was to clarify the characteristics of patients with unconfirmed auditory processing disorder (APD) by evaluating their attention, memory, development, and mental aspects as well as their performance on the auditory processing test (APT). Four cases of unconfirmed APD in this study passed a basic hearing test but scored less than 109 points on the check sheet of hearing difficulties. The test battery included APT, clinical assessment for attention (CAT), the standard language-related examination of paired-associate learning (S-PA), Rey-Osterrieth Complex Figure Test (ROCFT), nonword repetition subtest of Sophia Analysis of Language in Aphasia (SALA), Japanese editions of Autism-Spectrum Quotient (AQ), Conners' Adult ADHD Rating Scales (CAARS^TM) and Self-rating Depression Scale (SDS). The 4 cases differed in their results of APT and how strongly their APT performance related to short-term memory, distributed/reverted attention, sustained attention, mental fatigue and hyperactivity/restlessness. Multifaceted evaluation revealed that there are individual differences in factors underlying APD symptoms.
