Chronic pain affects 1.5 billion people worldwide, an estimated 100 million of whom live in the United States. Yet we currently have no effective treatment options. Fortunately, research advances have determined some of the ways in which chronic pain changes the brain, and several promising research areas could lead to better treatment approaches.
Chronic pain is a frequent health problem in the elderly and is not part of the normal aging process. The prevalence levels range between 45% and 80% in line with an age-related increase in patient comorbidity. Chronic pain is usually defied as lasting onwards of three months or pain that persists after an injury has fully healed. Research has highlighted the association of chronic pain in the elderly to loss of independence, poor diet and social isolation. Importantly as with many disease processes, chronic pain and its subsequent affects upon life is not evenly distributed throughout the population. Females and patients from a lower socioeconomic status have been shown to report more chronic pain.
Assessing pain accurately and communicating it to the healthcare team is clearly the keystone for effective management of pain. However, there are significant obstacles to doing this accurately in patients with cognitive impairment. These obstacles, particularly language deficits, make it challenging for the patient to convey the pain they are feeling. In addition, AD is can be associated with challenging patient behavior, often as a result of pain, that can make physical assessment difficult. In line with the fact that many elderly patients suffer from persistent pain, a methodical approach must be taken with patients with underlying cognitive impairment to avoid under-treating a patient for pain syndromes.
Evaluating pain is best done in two distinct parts:
Is the patient experiencing pain? There are a wide range of validated pain assessment tools that can aid healthcare professionals, caregivers, and families in making decisions about a patient’s pain management. The selected assessment tool can vary between regions and certainly varies between countries. It is important for healthcare professionals to become familiar and competent with the locally approved pain assessment tools.
Evaluate the nature of pain syndrome;
In simplistic terms, there are four chronic pain syndromes that are important to differentiate due to variation in subsequent management.
Firstly, the most common syndrome in the general population is the pain due to excess of nociceptive inputs. Secondly, neuropathic pain is an intensively painful syndrome brought about by nerve injury or dysfunction of nerve pathways. Differentiating between neuropathic and nociceptive pain syndromes has important implications for diagnostic and treatment decisions. Thirdly, chronic pain syndrome (or dysfunctional pain syndrome) is a constellation of syndromes that do not respond adequately to medical care. Finally, in a hospital setting it is common for patients to present with mixed pain syndrome. The classic example is a patient with cancer, as due to the nature of the disease, the patient can experience a number of different forms of pain
Approaching chronic pain as a national emergency would allow for a better future in terms of both treatments for chronic pain, costs to society, and individual well-being. It is time to take an honest look at where we are, get rid of unnecessary and unproven treatments, and advance neuroscience to the patient in the form of better treatments. Pain neuroscience has never been so exciting or well positioned in terms of the potential it offers to change the current impasse. But it will take bold decisions to put into place a vision and plan of action.
