Quick Q's about Migraines and Lou Gehrig's

[Wearia]

Not about if they're related, but just general questions about the two conditions.
I've been doing some research on them but still have a couple unanswered questions, namely:

1. Are there any real treatments for Lou Gehrig's Disease (besides stem cell research)? So far I've been able to find information on anti-depressants given to patients and vague allusions to medications that treat the damaged neurons.

2. Are migraines becoming more common in western society as opposed to say 3rd world countries? Or are they simply being diagnosed and understood more in modern life? (I'm trying to get at whether or not modern living contributes to migraines)

These are just the questions that I've been unable to find answers thus far. I have more, but hopefully I can dig up answers to them on my own. If not, I'll head on back here to ask them.
