「ICD-10 F40.1 社会恐怖(Social phobia)」の項に「家にこもりきり」という表記があるようだ。
【鑑別診断】広場恐怖やうつ病性障害は，しばしば顕著となり，両者とも患者を「家にこもりきり」にすることがある．社会恐怖と広場恐怖の鑑別が非常に難しい場合は，広場恐怖を優先すべきである．完全な抑うつ症状が明確に同定できなければ，うつ病の診断をくだすべきではない．
これはなんだと思って英語を見ると"housebound"という単語のようだ。
Differential Diagnosis
Agoraphobia and depressive disorders are often prominent, and may both contribute to sufferers becoming "housebound". If the distinction between social phobia and agoraphobia is very difficult, precedence should be given to agoraphobia; a depressive diagnosis should not be made unless a full depressive syndrome can be identified clearly.
"homebound"と同義。
Definitions:
1. confined to home: confined to the home, usually because of illness, age, or inability to travel
2. going home: moving or traveling toward home
