疎外 is a broader term for alienation or estrangement, often used in social contexts (e.g., alienation from society). 自己疎外 specifically refers to alienation from oneself.
アイデンティティの喪失 (loss of identity) is a related concept, but 自己疎外 emphasizes the estrangement or disconnect from one's own self rather than simply losing a sense of identity.
Compound of 自己 (self) and 疎外 (alienation). The term is a calque from Western philosophical and psychological concepts, likely entering Japanese through academic discourse in the 20th century.
