Symptoms Of Atypical Depression, Clinical Depression And The Flu

Q: If someone has the flu and feels miserable, are they clinically depressed while they have the flu? If not, why not? Can the symptoms of clinical depression be the same as the symptoms of the flu? If it is not too much trouble, please send e-mail as well as answering in the newsgroup. My news feed is not always that reliable (I often see replies to messages I never see). I am sometimes too ill to check my newsgroups for several days and my BBS/ISP never keeps more than 3-4 days worth of messages and sometimes keeps less than one days worth. Thank you in advance for all replies.

A:The short answer is "no", because the symptoms are not exactly the same, not all kinds of "miserable" are the same, etc. HOWEVER, some symptoms overlap: anorexia, for example; but still others are more like "atypical depression", in which overeating (OR perhaps carbohydrate craving?) is reported, and the most notable symptom is lethargy. Poor concentration is likely in all three (flu, typical depression, atypical depression). Those who have seen some of my postings (espec. in bionet.neuroscience and bionet.immunology) know I have an interest in the role of IL-1 in these phenomena. IL-1 is known to be increased (in the brain and elsewhere) by infection (among other things), and has been reported to be elevated in the serum of atypical depressives but NOT in typical depressives (nor dysthymics)--poster by J. Griffiths et al. at Society for Neuroscience Nov.96. My SUSPICION is that while some aspects of atypical depression may be produced by flu (poor concentration, lethargy, etc.), "mood" or "emotional" or "attitudinal" aspects may not be, usually--but MIGHT be in someone predisposed to depression (e.g. by family history or personal history). (By "mood" etc., I mean sadness, pessimism, guilt, poor self-esteem, inability to feel pleasure, etc.) What if someone has flu symptoms that last longer than the flu is "supposed" to last? Would it be justifiable to diagnose that person with clinical depression? If you inject normal people with IL-1 do they start having the symptoms of atypical depression? What is atypical depression? Is it a specific set of symptoms (for example increased appetite, irritated mood and hypersomnia) or is it any kind of depression with any unusual symptoms or not enough symptoms to meet the requirements of the DSM? If it is not too much trouble, please send e-mail as well as answering in the newsgroup. My news feed is not always that reliable (I often see replies to

messages I never see). I am sometimes too ill to check my newsgroups for several days and my BBS/ISP never keeps more than 3-4 days worth of messages and sometimes keeps less than one days worth. Thank you in advance for all replies. Don't know if there are studies with normal people, but when given to cancer patients it causes lethargy, concentration problems, etc.--perhaps in some cases other aspects, e.g. depressed mood--however, anorexia more likely than overeating. I have a hunch these can become dissociated (as these are from fever after a few days). For example, IL-1 also causes lower blood sugar, which must surely work against some anorexic mechanisms.
