This study evaluated the incremental utility of neuropsychological tests to computed tomography (CT) in predicting long-term outcomes of adults with moderate to severe traumatic brain injury (TBI). Participants were 288 adults with mild complicated, moderate, and severe TBI. Longitudinal data were evaluated during inpatient status in an urban rehabilitation hospital with a TBI Model System, as well as 1 and 2 years post injury. ⋯ Neuropsychological evaluations uniquely contributed to outcome predictions of functional disability, even after considering demographic and injury severity characteristics, including information from CT. In contrast, CT characteristics were not predictive of long-term functional disability at 1 or 2 years post TBI. Taken together, the findings indicate that neuropsychological tests add unique predictive information for long-term functional outcomes after TBI.

Opioid analgesics provide effective treatment for noncancer pain, but many health providers have concerns about cognitive effects, tolerance, dependence, and addiction. Misuse of opioids is prominent in patients with chronic pain and early recognition of misuse risk could help providers offer adequate patient care while implementing appropriate levels of monitoring to reduce aberrant drug-related behaviors. Many persons with chronic pain also have significant medical and psychiatric comorbidities that affect treatment decisions. ⋯ The assessment of different domains using semi-structured interviews, sensory and neuropsychological testing, and standardized self-report measures permits identification of somatosensory, emotional, cognitive, behavioral, and social issues in order to facilitate treatment planning. In this review we discuss opioid abuse and misuse issues that often arise in the treatment of patients with chronic pain, and present an overview of assessment and treatment strategies that can be effective in improving outcomes associated with the use of prescription opioids for pain. Finally we briefly discuss the effect of opiate analgesics on cognition and review some intervention strategies for chronic pain patients.

Back pain is experienced by up to of 85% of the United States population. Most often it resolves with minimal to no medical treatment. For those whose pain endures, worsens, or becomes protracted, conservative care is typically first attempted. ⋯ Empirical findings with the MMPI-2 Restructured Form (MMPI-2-RF) are presented next, including descriptive analyses with a sample of 1341 individuals assessed as part of a pre-surgical psychological screening. Correlations between MMPI-2-RF scale scores and measures of the primary risk factors identified in this review are reported for a smaller sample of 197 pre-surgical candidates. Interpretive implications of the MMPI-2-RF findings are discussed along with suggestions for further research in this area.

Current combat veterans are exposed to many incidents that may result in mild traumatic brain injury (mTBI) and/or posttraumatic stress disorder (PTSD). While there is literature on the neuropsychological consequences of PTSD only (PTSD-o) and mTBI alone (mTBI-o), less has been done to explore their combined (mTBI+PTSD) effect. The goal of this study was to determine whether Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) veterans with mTBI+PTSD have poorer cognitive and psychological outcomes than veterans with PTSD-o, mTBI-o, or combat exposure-only. ⋯ Effect sizes tended to be large in both groups with PTSD. Thus, PTSD seems to be an important variable affecting neuropsychological profiles in the post-deployment time period. Consistent with literature on civilian mTBI, the current study did not find evidence that combat-related mTBI in and of itself contributes to objective cognitive impairment in the late stage of injury.

Fibromyalgia is a chronic pain-related disorder that typically includes cognitive complaints as well as non-specific somatic complaints, such as fatigue and sleep disturbance (Wolfe et al., 2010). Fibromyalgia has also been shown to be associated with a high rate of failure on performance validity testing (PVT), which has not been examined with respect to other self-reported symptoms that are now part of the diagnostic criteria for the disorder. We evaluated 85 patients with fibromyalgia who completed objective measures of pain, sleep, and fatigue along with symptom validity measures (Word Memory Test or Test of Memory Malingering and Reliable Digit Span). ⋯ Disability status analyses were significant for daily pain, weekly pain, and fatigue, but not sleep. The implication of this study is that PVT performance and disability status are associated with exaggeration of non-cognitive symptoms such as pain, sleep, and fatigue in persons with fibromyalgia. This study reinforces the importance of effort testing when working with medical populations.
