suffers with/from

Tang it's done either way

Let's ask Tes however, which is better

I would prefer 'from', which is always considered correct, whereas many people see 'with' as an error.

Thanks to both of you.

Using suffers would be a problem in North America. Not a grammatical problem. There's an implication of judgment if language like suffer/suffers is used.

An arbitrator recently questioned a doctor's bias on a file I worked on when the report said "this unfortunate .... .... suffers from .... ". The report was thrown out.

More acceptable language would be "has been diagnosed with depression".

I got corrected once by a friend when I spoke about a schizophrenic.

He said, "We don't say that anymore. We say he/she has schizophrenia."
