Fair enough, re-reading the article implies that the article itself is misleading, especially in talking about both the primary and secondary syndromes in conjunction - implying that J would probably not get any attacks if she didn't smoke and didn't drink coffee where in fact they are only worsening factors (ie if her hands do get cold the attack will be worse if she's been smoking and drinking caffeine)

Interestingly, while I agree that migraine is transitry, surely if we're talking avoiding certain trigger factors to avoid an attack then surely there will be some kind of permanent underlying cause - as is the same with gout (when avoiding certain foods) and Reynaud's (when avoiding the cold). Of course, it's very difficult to specify this as I'm completely convinced that migraine is an umbrella term for a number of different types of single focus or cluster headaches, all of which have different underlying causes.
