Does having chronic migraines injure the brain and cause Alzheimer's? My dad always had migraines and now has Alzheimer's. I have had migraines since my 30's and have scarring on my brain. I do see a neurologist but he doesn't think it causes the disease. My kids also get them.

Your neurologist is right - there are no studies and no evidence suggesting migraines cause Alzheimer's disease.  Serious head injury resulting in unconsciousness in young adulthood is one of several risk factors for Alzheimer's.  Migraine injury to the brain is probably different, but I'm not a physician. 

It is likely there will never be a single cause for a common, complex and chronic disease like Alzheimer's.  There are multiple risk and protective factors which may increase or decrease your risk for Alzheimer's relative to other people.  Because Alzheimer's is such a common condition in later life, it is natural for people to look back and associate their Alzheimer's with conditions they had earlier like migraines.   For now, continue to seek help for your family migraine problem.  Getting migraines under control in the present is probably enough for you to deal with right now.

Actually there is some evidence that there is indeed a correlation between a history of migraines and an increased risk for Alzheimer - particularly for women. For example, in here:
