What is the difference between 無感動 and 無関心?


I know that both of them can be translated as “apathy”, but is there a
distinction between them? Are they interchangeable?




This 無 is a prefix meaning "-less". If you understand the difference between
感動 and 関心, the difference between 無感動 and 無関心 is almost self-evident. 関心 is
"interest" or "curiosity", whereas 感動 is "(emotional) movement" or
"excitement"
