OBJECTIVES The primary aim of this pilot investigation was to identify structural brain differences in older adults with chronic low back pain (CLBP) as compared with pain-free individuals. DESIGN Cross-sectional, case-control. PARTICIPANTS Sixteen cognitively intact older adults, eight with CLBP and eight pain-free; excluded if with psychiatric or(More)
OBJECTIVE Chronic pain and cognitive impairment are prevalent and disabling in older adults (OA), but their interrelationship has not been rigorously tested. We did so in OA with chronic low back pain (CLBP). DESIGN A total of 323 OA (160 pain-free, 163 CLBP; mean age 73.5 years, 45% female) had neuropsychological (NP) testing with the Repeatable Battery(More)
Is the spatial attention system divided into separate, modality-specific subsystems, or is there a supramodal spatial attention system? More specifically, does the role of the parietal lobe in spatial attention involve modality-specific or supramodal mechanisms? We addressed this question using a variant of Posner's spatial cuing task. Parietal-lesioned(More)
This study examined the interrelationships among occupational exposure to mixtures of organic solvents, neurobehavioral functioning, and complaints of cacosmia. The latter was defined as nausea, headaches, and subjective distress in individuals exposed to neutral environmental odors. The authors administered a battery of cognitive tests to men with and(More)
Neuropsychologists are being increasingly called upon to assess the neurobehavioral status of adults who have been exposed to toxic chemicals or heavy metals in the workplace. Unfortunately, the evaluation of blue-collar workers has been hampered by the absence of a brief yet comprehensive battery of sensitive neuropsychological tests that have been(More)
Mutations of the insulin receptor gene are a cause of the type A syndrome of extreme insulin resistance. This study assessed the prevalence of such mutations in women with clinical features of the type A syndrome including ovarian hyperandrogenism, moderate-to-severe degrees of insulin resistance, and acanthosis nigricans. We studied 22 unrelated women with(More)
Sensitization in the neuroscience and pharmacology literatures is defined as progressive increase in the size of a response over repeated presentations of a stimulus. Types of sensitization include stimulant drug-induced time-dependent sensitization (TDS), an animal model related to substance abuse, and limbic kindling, an animal model for temporal lobe(More)
Subjective memory complaints (SMCs) are known to be inconsistently related to current memory impairment in older adults but this association has not been well investigated in primary care provider (PCP) settings. To characterize the complexity of the relationship between SMCs and objective memory in older outpatients of PCPs, we collected(More)
Memory and attention were evaluated in 40 persons with a history of organic solvent exposure and 40 demographically similar controls. Exposed subjects, in comparison to controls, had reduced digit spans, were deficient at learning new information, and recall on a Brown-Peterson distractor test was especially low following a 30-sec interference interval. If(More)
IMPORTANCE Treatment of chronic low back pain (LBP) in older adults is limited by the adverse effects of analgesics. Effective nonpharmacologic treatment options are needed. OBJECTIVE To determine the effectiveness of a mind-body program at increasing function and reducing pain in older adults with chronic LBP. DESIGN, SETTING, AND PARTICIPANTS This(More)
