(D) between mood swings, perhaps violent without being grounded in mental disease, from genuine manic-depressive psychosis
(E) genuine manic-depressive psychosis and mood swings, which may be violent without being grounded in mental disease

I have question about D.

If i used "and" instead of "from" in D, will it be correct?

What is the difference between "Mood swings, perhaps violent without being grounded in mental disease" and "mood swings, which may be violent without being grounded in mental disease"?

Thanks.

The idiom is either to Distinguish X From Y or to distinguish Between X AND Y.

As for D, even if 'and' replaces the 'from', the sentence would still be considered awkward in terms of the modifier placement of the whole phrase and what is described. A clause makes it clearer in this case what is violent; it is also awkward to say "he is perhaps violent" as opposed to "he may be violent"; the distinction seems to be in what is being described- it is not the violence that is 'perhaps' (so to speak), but the 'he' that is the focal point. This applies to the mood swings in the example as well. Use of the clause clarifies this.
