WEDNESDAY, May 22 (HealthDay News) -- People who endure chronic migraines or back pain are more likely to attempt suicide, whether or not they also suffer from depression or another psychiatric condition, according to a new study.
"Clinicians who are seeing patients with certain pain conditions should be aware they are at increased risk of suicide," said study co-author Mark Ilgen, of the Veterans Affairs Serious Mental Illness Treatment Resource and Evaluation Center in Ann Arbor, Mich.
"Although undoubtedly psychiatric factors are important, there might be aspects of the pain that in and of themselves increase a person's risk," Ilgen said. "There might be something about someone with significant pain that puts them at increased risk."

Researchers identified those suffering from chronic pain and tracked them for the next three years to see if any died from suicide.
The research team then looked for associations between suicide death -- the 10th most common cause of death in the United States -- and clinical diagnoses of chronic pain conditions, such as arthritis, back pain, migraines, neuropathy, headaches or tension headaches, fibromyalgia and psychogenic pain.

Dr. Elspeth Cameron Ritchie, a retired Army colonel and psychiatrist living in Washington, D.C., said the study clearly reinforces the an
