ABSTRACT To examine the impact of distraction on the retention of rehearsed information in patients with fibromyalgia syndrome (FMS).
Data refer to the neurocognitive examination of 134 patients (91 with FMS and 43 control subjects) presenting with memory loss. Four neurocognitive measures free of distraction, along with 2 measures with added distraction, were completed. Differences in the retention of rehearsed and unrehearsed information with a source of distraction present were calculated.
Patients with FMS showed normal cognitive functioning on verbal memory tests free of distraction. Adding a source of distraction caused unrefreshed information to be lost at a disproportionate rate in patients with FMS. Over 87% of patients with FMS scored in the impaired range on a task of unrehearsed verbal memory. Adding a source of distraction to well-rehearsed information produced a normal rate of recall in FMS.
Rehearsal mechanisms are intact in patients with FMS and play beneficial roles in managing interference from a source of distraction. In the absence of rehearsal, a source of distraction added to unrefreshed information signals a remarkable level of cognitive deficit in FMS that goes undetected by conventionally relied-upon neurocognitive measures. We present a theory to promote understanding of the cognitive deficit of people with FMS based on reduced speed of lexical activation and poor recall after distraction.

    ABSTRACT: INTRODUCTION. People with a fibromyalgia diagnosis complain of having very poor cognitive functioning. In recent years, there has been an increasing interest to investigate which cognitive impairment is present in this disease. AIM. To review the published research on fibromyalgia and cognitive dysfunction. DEVELOPMENT. A literature search was performed with a time interval from 1995 to 2012. Search terms included the keywords 'fibromyalgia' and 'cognition', 'attention', 'memory', 'language', 'perception', 'executive functions' and 'dis-executive syndrome'. 64 records were selected after applying inclusion criteria. CONCLUSIONS. Studies that have examined cognitive function in people diagnosed with fibromyalgia have been few and mostly with small samples. Deficits have been identified mainly in working memory and complex attentional functions, where the distraction factor has an important significance. Impairment has also been identified in long-term memory and executive functions. There is consensus among the studies in which the degree of pain is directly related to the level of cognitive dysfunction, while no full consensus to explain the influence of depression and anxiety on cognitive functioning in these patients.

    ABSTRACT: We review recent heat capacity and magnetotransport experiments on GaAs/AlGaAs heterostructures containing multilayer two-dimensional electron systems (2DESs) in the quantum Hall regime. Emphasis in this article is on the study of the heat capacity near Landau level filling factor ν=1. We also present a detailed survey of the development of the quantum Hall effect in tilted-magnetic fields for ν≲2. Among the novel phenomena we address is the strong coupling between the nuclear spins and the electrons associated with the spin phase transitions of the 2DES at ν=4/3 and near ν=1.
