'Imbecile' and 'moron' are stronger and sound more formal or old-fashioned. All are offensive when referring to disability.

Can I use 'imbecile' in academic writing?

Only if you are writing about the history of psychology or linguistics, and then it should be in quotes or clearly marked as a historical term. It is not acceptable in modern academic discourse to describe people.

Is the adjective 'imbecilic' as offensive as the noun?

Yes, it carries the same offensive connotations when applied to a person's actions or ideas. It is slightly more abstract, but still very derogatory.
