CBS news is reporting on a new study finds that people with migraines who also are depressed have smaller brains. "Our study suggests that people with both migraine and depression may represent a unique group from those with only one of these conditions," study author Dr. Larus S. Gudmundsson, a researcher at the National Institute on Aging and the Uniformed Services University of the Health Sciences, in Bethesda, Md., said in a news release.

The study authors set out to see how having both depression and migraines affected people's brains. Their research was published May 22 online in Neurology.

This isn't the first study to report brain changes associated with migraines.

A March study in Radiology found migraine sufferers had less tissue over the part of the brain that processes pain.

A Nov. 2012 study in JAMA found women who suffered from migraines were more likely to have small lesions in their brains.

However, recent research is giving great hope to migraine sufferers. Dr. Scott Rosa, upper cervical chiropractor from New York has been doing some amazing research with upright MRIs. He's been able to show that when someone has a misalignment in the upper neck it is actually changing the flow of cerebral spinal fluid (CSF) to, from and through the brain. CSF is the fluid that lubricates the brain and spinal cord.

This research is consistent with the findings of the upper cervical organization looking at changes in blood flow to and from the brain with phase contrast MRIs in migraine patients.

The obstruction comes as the first few bones in your neck becomes misaligned and causes a backup of CSF and blood leading to increased intracranial pressure. When this misalignment was corrected by an upper cervical procedure such as upper cervical, the studies show that the pressure decreases by 28.6%! And the CSF flow becomes normal. These CSF and blood flow changes may be the underlying reason for the changes that are being recognized in the research.

So those migraine headaches are not just pain, but they are doing severe damage to your brain.
