Psychological assessment and treatment of patients with neuropathic pain.

Studies on the psychological assessment and treatment of neuropathic pain conditions, including postherpetic neuralgia (PHN), diabetic neuropathy, complex regional pain syndrome, post spinal cord injury, post amputation, and AIDS-related neuropathy, are reviewed. Although limited information is currently available, the findings are consistent with the larger literature on chronic pain and indicate that the assessment of neuropathic pain needs to include measurement of multiple dimensions of quality of life. Mood, physical and social functioning, and pain-coping strategies such as catastrophizing and social support are all important domains. Clinical trials of psychological interventions have not been reported in the scientific literature. Case series of successful treatment of neuropathic pain are reported, primarily in the area of biofeedback. As with other chronically painful conditions, it is likely that cognitive-behavioral interventions will improve the quality of life in neuropathic pain conditions.

Psychological aspects of neuropathic pain.

Studies on the psychosocial impact of neuropathic pain conditions, including postherpetic neuralgia, diabetic neuropathy, complex regional pain syndrome, post spinal cord injury, postamputation, and AIDS-related neuropathy, are reviewed. Although limited, data are consistent with the larger literature on chronic pain and indicate that neuropathic pain reduces quality of life, including mood and physical and social functioning. Depression and pain coping strategies such as catastrophizing and social support predict pain severity, and a single diary study demonstrates a prospective relation between depressed mood and increased pain. Clinical trials of psychological interventions have not been reported, although some case series of successful treatment of neuropathic pain are reported, primarily in the area of biofeedback. Given the evidence indicating the broad impact of neuropathic pain on many areas of function, it is surprising that so few studies have investigated the impact of psychological interventions in these populations.
