RESUMO
Hemispatial neglect is one of the most frequent attention disorders after stroke. The presence of neglect is associated with longer hospital stays, extended rehabilitation periods, and poorer functional recovery. Transcranial direct current stimulation (tDCS) is a new technique with promising results in neglect rehabilitation; therefore, the objective of this systematic review, performed following the PRISMA guidelines, is to evaluate the effectiveness of tDCS on neglect recovery after stroke. The search was done in MEDLINE (PubMed), Web of Science, Scopus, Cochrane Library, and BioMed Central databases. A total of 311 articles were found; only 11 met the inclusion criteria, including 152 post-stroke patients in total. Methodological quality and risk of bias were assessed for all the studies, and methodological characteristics of the studies, sample sizes, methods, main results, and other relevant data were extracted. tDCS intervention ranged from one to twenty sessions distributed in 1 day to 4 weeks, with intensity ranged from 1 to 2 mA. We found moderate evidence for the efficacy of tDCS in the rehabilitation of hemispatial neglect after a stroke, being more effective in combination with other interventions. Nonetheless, the limited number of studies and some studies' design characteristics makes it risky to draw categorical conclusions. Since scientific evidence is still scarce, further research is needed to determine the advantage of this treatment in acute, sub-acute and chronic stroke patients. Future studies should include larger samples, longer follow-ups, and broader neurophysiological assessments, with the final aim of establishing the appropriate use of tDCS as an adjuvant intervention in neurorehabilitation settings.

INTRODUCTION: Motor fluctuations are one of the most common complications of Parkinson's disease and their treatment is still a complex matter. Therefore, from the Neurology Movement Disorders Group we present our clinical experience in the treatment of these complications, with the intention of it being useful in decision-making in daily clinical practice. DEVELOPMENT: Nineteen questions were developed based on a literature review and an open survey answered by members of this group. These issues were discussed in two phases, using the Delphi methodology. Considering the results of the survey, levodopa dose adjustment and dopamine agonists are the option with the best efficacy/tolerability ratio in the treatment of motor fluctuations. Rotigotine is useful in the motor fluctuations associated with gastroparesis, and intermittent subcutaneous apomorphine has positive effects in patients with unpredictable off periods. The most relevant adverse effect associated with dopamine agonists is impulse control disorder. Catechol-O-methyltransferase inhibitors are useful in the initial stages of motor fluctuations, especially in wearing off. Monoamine oxidase inhibitors are generally drugs that are well-tolerated and useful in motor fluctuations. If these measures are not effective, second-line treatments should be indicated on a case-by-case basis. CONCLUSION: The clinical profile of patients with Parkinson's disease is paramount in deciding the most appropriate therapy for the treatment of motor fluctuations.
TITLE: Experiencia clínica en el tratamiento de las fluctuaciones motoras en la enfermedad de Parkinson. Consenso Delphi de un grupo de expertos en trastornos del movimiento.Introducción. Las fluctuaciones motoras son una de las complicaciones más frecuentes en la enfermedad de Parkinson y su tratamiento sigue siendo complejo. Por ello, desde el Grupo de Trastornos del Movimiento de la Asociación Madrileña de Neurología presentamos nuestra experiencia clínica en el tratamiento de estas complicaciones, con la intención de que sea de utilidad en la toma de decisiones en la práctica clínica diaria. Desarrollo. Se elaboraron 19 preguntas a partir de una revisión bibliográfica y una encuesta abierta respondida por los miembros de dicho grupo. Dichas cuestiones se debatieron en dos fases, utilizando la metodología Delphi. Considerando los resultados de la encuesta, el ajuste de la dosis de levodopa y los agonistas dopaminérgicos son la opción con mejor relación eficacia/tolerabilidad en el tratamiento de las fluctuaciones motoras. La rotigotina es útil en las fluctuaciones motoras asociadas a gastroparesia, y la apomorfina subcutánea intermitente, en pacientes con off impredecible. El efecto adverso más relevante asociado a los agonistas dopaminérgicos es el trastorno del control de impulsos. Los inhibidores de la catecol-O-metiltransferasa son útiles en las fluctuaciones motoras de inicio, especialmente en el wearing off. Los inhibidores de la monoaminooxidasa son fármacos, en general, bien tolerados y útiles en las fluctuaciones motoras. En caso de que estas medidas no resulten eficaces, se deben indicar terapias de segunda línea de manera individualizada. Conclusión. El perfil clínico del paciente con enfermedad de Parkinson es primordial para decidir la terapia más adecuada en el tratamiento de las fluctuaciones motoras.

Room tilt illusion (RTI) is a transient disorder of the environmental visuo-spatial perception consisting of paroxysmal tilts of the visual scene. It is attributed to an erroneous cortical mismatch of the visual and vestibular three-dimensional coordinate maps. Thirteen subjects were included in this retrospective case series. Clinical presentation was 180º rotation of the visual scene following the coronal plane in seven patients. The most common cause for RTI in our series was posterior circulation ischaemia (five cases). Cases of endolymphatic sac tumour, critical illness neuropathy, acute traumatic myelopathy and multiple system atrophy causing RTI are reported for the first time. No case of supratentorial focal lesion was found. In order to describe the clinical and imaging features of RTI, 135 cases previously reported in the literature were reviewed along with our series. There was a male predominance (60.2 %). Mean age was 51.2 ± 20.3 years. The most common location of the injury was the central nervous system (CNS) (61.4 %). Supratentorial and infratentorial structures accounted for the same frequency of lesions. The most common aetiology was cerebral ischaemia (infarction or transient ischaemic episode; 27.7 %). These patients were significantly older and their lesions commonly involved posterior fossa structures when compared to patients with non-vascular disorders. In summary, RTI is a manifestation of several CNS and vestibular disorders, and rarely of peripheral nervous system disorders, triggered by disruption of vestibular and sensory perception or integration. Cerebral ischaemic disorders are the most common aetiology for this rare syndrome.
