I know that having migraines increase depression. I know this because I was not depressed before I got chronic migraines.
I found a recent study citing this article from the University of Toronto in Canada that has uncovered these disturbing statistics:
There is a higher rate of suicidal ideation (forming ideas around suicide) in younger migraine sufferers who have not yet learned coping skills to deal with this horrible medical condition. Even more shocking is that migraine disease is not yet seen in society as an illness that causes severe disability. (Oct. 17, 2013)
So... if you're under 30 you're WAY more at risk. What if you're over 30? Then what?
Here are some more disturbing statistics.
We already know that depression is higher with chronic pain sufferers, however this study shows that depression and suicidal ideation is "twice as high" in migraine sufferers.
Other statistics in the study are:
“In a paper published online this week in the journal Depression Research and Treatment, investigators also reported that younger migraine sufferers were particularly at risk for depression.” 
Unmarried migraine sufferers were also found to have higher probability of depression. I found these statistics so alarming. I guess I knew the stats for suicide and depression were higher for us migraine sufferers, but now it’s fairly current (2013) and the data foundation was significant.
The Canadian study drew data from a sample of over 67,000 Canadians in 2005, where 6,000 sufferers reported being diagnosed with depression.
This means 1 in 7 women and 1 in every 16 men or from what I can figure out, if my calculations are correct 8.95% overall of those 67,000 experience migraines.
Now the same study showed these stats for the risks for suicidal ideation, meaning the serious consideration of taking their lives:
Other factors effecting suicidal thoughts among migraineurs were: age, those under 30 years old had 4 times the likelihood compared to those over 65 years old; those unmarried; had lower household income and increased disabilities.
Duh! Could it be the pain or destruction of life?
I know from my own personal experience that I just did not have the right tools or coping skills back then to deal with this chronic migraine disease, forever! The former graduate student and co-author Meghan Schrumm says this:
It's important to take care of yourself, now that you know how much more chronic migraines increase depression.
Number one is always to see your doctor for the correct diagnosis.
Get clear on what you have been diagnosed with, so you can treat it effectively.
Keep a migraine diary so you can track changes and have a good record for your doctor.
There is a lot you can do to be proactive in your own treatment. Form a pain management strategy with your Doctor. Here are two articles to help with that:
Educate yourself so you can be proactive and make wise decisions. You have lifestyle choices and more resources available today, yes even the internet, than just a few years ago. Check out my course.
Now you know that migraines increase depression, you can take action. If this does spiral you down into a pit of depression, here's some more help:
Acknowledge and accept that there is currently no cure for migraines. I know this might sound difficult, but the sooner you realize you have a medical condition (like epilepsy) that needs to be taken care of, the sooner you can take the right action steps.
Please take good care of yourself,
