Patients with a psychogenic paresis have difficulties performing voluntary movements. Typically, diagnostic interventions are normal. We tested whether patients with a psychogenic lower limb paresis exhibit abnormal motor excitability during motor imagery or movement observation. ⋯ In patients with motor conversion disorder, the imagination of own body movements induces a reduction of corticospinal motor excitability whereas it induces an excitability increase in healthy subjects. This discrepancy might be the electrophysiological substrate of the inability to move voluntarily. Watching another person perform movements induces a normal excitability increase, indicating a crucial role of the perspective and suggesting that focusing the patient's attention on a different person might become a therapeutic approach.

The purpose of the study was to determine the degree of concordance between the self-report and the parent's proxy report of health-related quality of life (HRQoL) in school-going adolescents using the World Health Organization Quality of Life (WHOQOL)-BREF instrument in India. ⋯ Our study illustrated that fair to moderate agreement existed between parent proxy and subject's self-report for adolescent's HRQoL. That may be an indicator for suitability of parent's proxy report in certain dimensions, if a child is unavailable or unable to respond. However, further research may provide new insights into the determinants of concordance between subject self and parent proxy report of adolescent HRQoL.

Randomized Controlled Trial
A randomized controlled trial of quetiapine versus placebo in the treatment of delirium.
Delirium is a commonly occurring complex neuropsychiatric disorder. Evidence for its treatment based on randomized controlled trials (RCTs) is poor. ⋯ Quetiapine has the potential to more quickly reduce the severity of noncognitive aspects of delirium. This study was underpowered for treatment comparisons at specific points in time but nonetheless detected significant differences when analyzing the whole study period. While it is not possible to draw definitive conclusions, further larger studies exploring the use of quetiapine in other delirium populations seem justified. Larger increments in the dose of quetiapine may yield even stronger results.

(i) To analyze general practitioners' diagnosis of somatisation disorder (P75) using the International Classification of Primary Care (ICPC)-2-E in routine general practice. (ii) To validate the distinctiveness of the ICD-10 to ICPC-2 conversion rule which maps ICD-10 dissociative/conversion disorder (F44) as well as half of the somatoform categories (F45.0-2) to P75 and codes the other half of these disorders (F45.3-9), including autonomic organ dysfunctions and pain syndromes, as symptom diagnoses plus a psychosocial code in a multiaxial manner. ⋯ ICPC-2 P75 was mainly diagnosed in cases of severe MUS. Multiaxial coding appears to be too complicated for routine primary care. Instead of splitting P75 and F45.3-9 diagnoses, it is proposed that the whole MUS spectrum should be conceptualized as a continuum model comprising categorizations of uncomplicated (mild) and complicated (moderate and severe) courses. Psychosocial factors require more attention.

In recent years, a good deal of serious research has been carried out on the hypothesized presence of generalized hypervigilance to sensory stimulation in fibromyalgia (FM). However, there are no studies which, following an operationalization of generalized hypervigilance as a propensity to attend to any task-irrelevant stimuli presented, make use of interference paradigms as the most appropriate experimental models for its analysis. The purpose of this study was to test the hypothesis of generalized hypervigilance in FM using the emotional modification of the Stroop task and to explore the possible mediating role of anxiety. ⋯ These results suggest the presence of a generalized hypervigilance response in FM patients that is not mediated by anxiety. Implications for the correct functioning of controlled self-regulatory processes in fibromyalgia and similar pathologies are discussed.
