“…464 Although neglect improves over time, neglect symptoms continue to interfere with daily functioning long after stroke. [465][466][467] The interventions developed for neglect fall into 2 general categories: bottom-up approaches, designed to remediate attention processes for the left hemispace and internal representations of space, and top-down approaches, aimed at teaching the person strategies for compensating for neglect. 468 Most studies of neglect have been plagued by low-quality methods and small sample sizes.…”

e98Purpose-The aim of this guideline is to provide a synopsis of best clinical practices in the rehabilitative care of adults recovering from stroke. Methods-Writing group members were nominated by the committee chair on the basis of their previous work in relevant topic areas and were approved by the American Heart Association (AHA) Stroke Council's Scientific Statement Oversight Committee and the AHA's Manuscript Oversight Committee. The panel reviewed relevant articles on adults using computerized searches of the medical literature through 2014. The evidence is organized within the context of the AHA framework and is classified according to the joint AHA/American College of Cardiology and supplementary AHA methods of classifying the level of certainty and the class and level of evidence. The document underwent extensive AHA internal and external peer review, Stroke Council Leadership review, and Scientific Statements Oversight Committee review before consideration and approval by the AHA Science Advisory and Coordinating Committee. Results-Stroke rehabilitation requires a sustained and coordinated effort from a large team, including the patient and his or her goals, family and friends, other caregivers (eg, personal care attendants), physicians, nurses, physical and occupational therapists, speech-language pathologists, recreation therapists, psychologists, nutritionists, social workers, and others. Communication and coordination among these team members are paramount in maximizing the effectiveness

“…Numerous other areas have been associated with attention and neglect, including, amongst others, the right superior temporal gyrus (Karnath et al, , 2004, right temporal-parietal junction (TPJ; Corbetta et al, 2005), and right ventral frontal cortex (VFC; Corbetta et al, 2005;Rengachary et al, 2011). It would be worthwhile examining the involvement of these additional areas in visuospatial attention in near and far space in future research, and we are aware that researchers in other laboratories are currently investigating the role of areas such as VFC and TPJ in spatial processing.…”

“…It would be worthwhile examining the involvement of these additional areas in visuospatial attention in near and far space in future research, and we are aware that researchers in other laboratories are currently investigating the role of areas such as VFC and TPJ in spatial processing. Given the possible role for right VFC in mediating dorsal-ventral interactions (He et al, 2007;Rengachary et al, 2011) then this area would be of particular interest to investigate with regards to the issue of near and far space.…”

ABSTRACTVisuospatial neglect is a multicomponent syndrome and one dissociation reported is between neglect for near (peripersonal) and far (extrapersonal) space. Owing to patient heterogeneity and extensive lesions it is difficult to determine the precise neural mechanisms underlying this dissociation using clinical methodology. In this study transcranial magnetic stimulation was used to examine the involvement of three areas in the undamaged brain while participants completed a conjunction search task in near and far space. The brain areas investigated were right posterior parietal cortex (rPPC), right frontal eye field (rFEF), and right ventral occipital cortex (rVO), each of which has been implicated in visuospatial processing. The results revealed a double dissociation whereby rPPC was involved for search in near space only, whilst rVO only became necessary when the task was completed in far space.These data provide clear evidence for a dorsal and ventral dissociation between the processing of near and far space, which is compatible with the functional roles previously attributed to the two streams. For example, the involvement of the dorsal stream in near space reflects its role in vision for action, since it is within this spatial location that actions can be performed. The results also revealed that rFEF is involved in the processing of visual search in both near and far space, and may contribute to visuospatial attention and/or the control of eye-movements irrespective of spatial frame. We discuss our results with respect to their clear ramifications for clinical diagnosis and neurorehabilitation.Lane, 3

“…Un año después del ictus, los pacientes con HVE pueden seguir mostrando los sínto-mas propios de esta alteración (Karnath, Rennig, Johannsen, y Rorden, 2011;Rengachary, He, Shulman, y Corbetta, 2011). En un estudio reciente, Nijboer, Kollen y Kwakkel (2012) han investigado la persistencia temporal de la HVE en una muestra de 101 pacientes con un ictus en el hemisferio derecho; de estos pacientes, 51 presentaron HVE.…”

ResumenObjetivo: Realizar una revisión descriptiva sobre la heminegligencia visuo-espacial asociada a accidentes cerebro-vasculares. Se abordan los aspectos clínicos y teóricos más relevantes, así como las diferentes técnicas de intervención utilizadas actualmente. Desarrollo: La heminegligencia visuo-espacial es un déficit neuropsicológico multimodal asociado a lesiones cerebrales, principalmente de origen vascular. Su presencia implica una recuperación más lenta, mayor discapacidad y una respuesta precaria a la rehabilitación. Aunque la recuperación espontánea puede ocurrir en el transcurso de las primeras semanas o meses, el paso del tiempo no necesariamente implica una mejora de los síntomas. A día de hoy se han desarrollado múltiples estrategias de rehabilitación, pero son muy pocas las que demuestran efectos perdurables en el tiempo. Conclusiones: La adaptación de prismas es la técnica con la que se obtienen mejores resultados, aunque existen controversias respecto a sus beneficios a largo plazo. Las diferentes intervenciones que se describen en el artículo tienen un impacto transitorio y los resultados no acostumbran a traducirse en una mejora en las actividades de vida diaria. Las tendencias actuales apuestan por la aplicación combinada de diferentes técnicas.
