Psychogenic movement disorders are movement disorders that cannot be attributed to any known organic disease and which are caused by an underlying psychiatric pathology or are due to voluntary simulation. They account for 1-3% of all movement disorders. ⋯ Although in recent years some progress has been made in our knowledge of psychogenic movement disorders, more research is needed to determine the mechanism underlying these pathologies, as well as the techniques and complementary tests that can help reach a diagnosis. Further studies on treatment are also required.

Tremor is the most common movement disorder. The differential diagnosis on its origin is sometimes difficult and the number of conditions that include this symptom as part of their clinical spectrum continues to increase. ⋯ In this paper we review the data available today that help in the differential diagnosis of tremor; the particularities concerning Parkinson's disease from the diagnostic, therapeutic and genotypic point of view are also discussed.

Comparative Study[Comparative study of meningitis due to Staphylococcus aureus and coagulase-negative Staphylococci in adults].
Staphylococcus spp. rarely cause community-acquired acute bacterial meningitis (ABM), but they are a frequent cause of nosocomial meningitis. AIMS. We describe and conduct a comparative analysis of ABM due to S. aureus and coagulase-negative (CoN) Staphylococci in adults. ⋯ Staphylococcus spp. are a frequent cause of ABM in hospitals with neurosurgery, especially in the post-operative period following neurosurgical procedures and/or in carriers of CSF drainage devices. Prognosis in infections caused by CoN Staphylococci is favourable, in contrast to the high mortality rate caused by S. aureus.

[Insomnia Severity Index: some indicators about its reliability and validity on an older adults sample].
The Insomnia Severity Index (ISI) is a short instrument developed to assess insomnia severity from which there is no study in Spain that guarantees its psychometric properties. ⋯ First data of the Spanish version of the ISI endorse single-dimensional structure, with an appropriate internal consistency reliability, and evidences of its measures validity.
