聴覚失認を呈した一症例のコミュニケーション改善に向けた視覚性注意機能訓練と視覚的代償訓練の効果

Effects of optic attention functional training and alternative methods using visual modality for communication improvement of auditory agnosia: A case study

要旨：聴覚失認とは，聴覚による言語や環境音の認知が困難になる状態であり，横側頭回や聴放線の損傷によって生じるとされている．今回，聴覚失認を呈した60歳代の症例を経験した．もともと社交的な本症例であったが，聞き取りの困難さから周囲との交流を避けるようになっていった．作業療法において読話を用いた視覚的代償戦略を用いることで，聴覚失認の症状自体は変化を得られないなかでもコミュニケーションの困難さを克服しだし，周囲との交流を取り戻し始めた．コミュニケーションの障害を言語機能障害ととらえず，生活障害としてとらえて，作業療法士も積極的に介入していく必要がある．

　Auditory agnosia refers to impairments in auditory recognition of verbal and environmental sounds, caused by injury of the transverse temporal gyrus or acoustic radiation. We experienced a case of a woman in her 60s who presented with auditory agnosia. Originally a sociable person, the case began to have difficulty in communicating with others due to the problem with listening. Occupational therapy included alternative methods using visual modalities, like lipreading. The case overcame the communication difficulty and regained the relationships, while no improvement was seen in auditory agnosia itself. Occupational therapists have to participate in rehabilitation for the patients with difficulty in communication, regarding it as a handicap in daily life, not as an verbal impairment.
