Blinded white cells and schizophrenic tendancy ?

Do blinded white cells in lupus condition have schizophrenic tendancies?

I know this probably sounds far fetched but I was wondering if anyone could shed light on this! My friend who has lupus has occasional flare ups and when she does, she almost stats behaving schizophrenic! Not in the extreme, that she starts sel-harming but more in her behavioural tendancies, eg. she becomes demotivated, quiet, doesn't talk much and doesn't have much energy to do anything. In her worse flare ups, she gets swollen limbs and sweats heavily at night. This is slightly worrying to outsiders, such as me, looking in and seeing her gradually becoming whiter, weaker and her immune system corrupt! On the upside she continues to work, she's happy, has plenty of friends and tries to not let it affect her!

The link that I'm making with the blinded white cells, which we knows turn on each other and cause lupus, might be able to be treated if we could find a medication that alters behaviour of white cells. I know there's plenty of lupus meds you can take. However I'm dreading the day they might not have much effect, since my friend's lupus is steadily getting worse, she's recently had her medication doubled. We need a new way of altering the white cells' behaviour - maybe by studying actually how the white cells behave under a scope. I wish we could try and work out the 'brains' of white cells and try and work out how to make them coodinated so they don't disrupt the immune system and cause lupus.
