Mental health is an issue for people with spinal cord injury. Chronic pain makes it worse

Adults living with spinal cord injuries have a near-80% increased risk of developing psychological conditions, such as depression and anxiety, compared to people without the traumatic injury, a new study shows. But chronic pain may have an equally large, negative effect on mental health.

The study is published in Spinal Cord by a Michigan Medicine-led team of researchers who analyzed private insurance claims from more than 9,000 adults with a traumatic spinal cord injury and more than 1 million adults without. They accounted for a range of psychological conditions, from anxiety and mood disorders to insomnia and dementia.

People living with a spinal cord injury were diagnosed with a mental health condition more often than those without the injury – 59.1% versus 30.9%. While depression and adverse mental health effects are not inevitable consequences of every traumatic spinal injury, past findings have consistently echoed higher levels of psychological morbidity among this group than the general population without spinal cord injuries.

In this study, however, chronic centralized and neuropathic pain among adults living with a spinal cord injury were found to be robustly associated with post-traumatic stress disorder, substance use disorders and other mental health conditions. In most cases, chronic pain was an even greater influence on these conditions than exposure to living with the injury itself.

Researchers say the findings should prompt physicians to identify mental health conditions when seeing patients with spinal cord injuries and refer them to mental health providers for treatment.

"Improved clinical efforts are needed to facilitate screening of, and early treatment for, both chronic pain and psychological health in this higher-risk population," said Mark Peterson, Ph.D., lead author of the paper and associate professor of physical medicine and rehabilitation at Michigan Medicine.

However, researchers note a lack of insurance coverage and limited available services will likely cause the issue to remain largely unaddressed.

"Stakeholders need to work together to lobby for more federal research funding and special policy amendments to ensure adequate and long-term insurance coverage for both physical and mental health to meet the needs of folks living with spinal cord injuries," Peterson said.
