Major depression is thought to be four times greater in people with chronic back pain than in the general population.
Depression is more commonly seen in patients with chronic back pain problems, this is due to a number of factors:
- The pain often makes it difficult to sleep, leading to fatigue and irritability during the day.
- Then, during the day, because patients with back pain have difficulty with most movement they often move slowly and carefully, spending most of their time at home away from others. This leads to social isolation and a lack of enjoyable activities.
- Due to the inability to work, there may also be financial difficulties that begin to impact the entire family.
- Beyond the pain itself, there may be gastrointestinal distress caused by anti-inflammatory medication and a general feeling of mental dullness from the pain medications.
- The pain is distracting, leading to memory and concentration difficulties.
- Sexual activity is often the last thing on the person’s mind and this causes more stress in the patient’s relationships.
These symptoms accompanying chronic back pain or neck pain may lead to feelings of despair, hopelessness, inability to enjoy anything and other symptoms of a depression.
Anxiety and Back Pain
Patients with back pain, can also present with anxiety. This may be caused by a worry about their pain, its cause, the treatment, and the future. Understanding all the facts is important, in reducing these fears. For example- patients often ask if there can end up in a wheelchair either without or with treatment. The chances of this are extremely small!
Some patients who suffer from anxiety and worry in their lives anyway, suffer more with these symptoms when they get back pain.
It is also widely recognised that patients with anxiety or depression experience more pain than those who do not .
This is because even though pain is generated in the spine, its is processed in the pain centre in the brain. Each part of the brain affects other parts- so if one is depressed one can experience more pain, and pain in turn can cause people to feel depressed.
Psychological theories about depression
Chronic back pain can lead to a diminished ability to engage in a variety of day to day activities. This situation leads to a downward physical and emotional spiral. As this continues, the person with chronic back pain feels more and more loss of control over his or her life, leading to major depression. Once in this depressed state, the person is feels unable to change the situation and stuck in a rutt.
Depression impacts spine surgery outcome
Research has clearly demonstrated that non-physical variables such as depression, anxiety, thought patterns, and personality style can impact spine surgery outcome.
Spine surgery patients who are clinically depressed pre-operatively may continue to display depressive symptoms post-operatively and these can negatively impact the surgery outcome. Particular symptoms that may impede post-operative recovery include such things as low motivation, sleep disturbance, slower healing time, difficulty with physical rehabilitation and inability to perceive improvements
If a patient is facing a spine surgery and has a chronic back pain problem with significant depression, he or she may want to consider postponing the surgery until the depression can be treated.
If the depression is caused purely by the pain, then it often improves after successful surgery. If there are other life factors causing depression- like work/family/money related stresses- then they may interfere with the outcome of surgery. Only the patient can tell the difference.

Depression is a commonly missed diagnosis
One of the biggest problems in treating major depression for the patient with chronic back pain is missing the diagnosis. This occurs for two reasons: the chronic back pain patients often do not realize they are also suffering from a major depression, and the doctor is not looking for depression.
The depressive symptoms may be downplayed by the chronic back pain patient who believes that, “just get rid of this pain and I won’t feel depressed” or that acknowledging depression is a sign of weakness in dealing with the pain. When the diagnosis of major depression in the chronic back pain patient is missed or ignored, treatments strictly directed at the pain are much more likely to fail.
Simultaneous treatment for depression and chronic back pain
Pain and the depression should be treated simultaneously in a multidisciplinary fashion. The treatment of clinical depression most often includes psychological interventions (e.g. counseling, relaxation training, etc), exercise and anti-depressant medication.
Treatment for the chronic pain might include such things as physical rehabilitation aimed at restoration of function, trying to “normalize” one’s life as much as possible even with the pain, appropriate medication management, among other things. Multidisciplinary treatment of the chronic back pain and major depression will ultimately give the patient more of a sense of control over the pain and start a springboard toward physical and mental re-conditioning.
Cognitive behavioural therapy is a well recognised treatment for depression linked to back pain.
Assessing depression
We use a variety of means of assessing for depression in all back pain patients at North Tees Spinal unit. Depression questionnaires can alert us to the presence and severity of their depression. If depression is diagnosed it can be treated using a multi-disciplinary approach in addition to treatment of backpain, resulting in a better outcome for the patient.
