“…As far as we know, this is the first study which has investigated the effects of bihemispheric stimulation on the recovery of language. As stated in the Introduction, several studies have already stressed the importance of associating specific language training with anodic unihemispheric tDCS stimulation over the perilesional language areas (Baker et al ., ; Fiori et al ., ; Fridriksson et al ., ; Marangolo et al ., ). This was based on the assumption that, in chronic patients, language recovery may be associated with the reactivation of left‐hemispheric perilesional structures (Warburton et al ., ; Saur et al ., ; Winhuisen et al ., ).…”

“…The aim of the present study was to investigate whether bihemispheric frontal stimulation would enhance language recovery and, in particular, language articulation, in a group of left chronic aphasic persons. Bihemispheric tDCS may potentiate the effects of anodic stimulation to the left lesioned hemisphere (Fiori et al ., ; Marangolo et al ., , ) through additional modulation of interhemispheric interactions via cathodic stimulation to the homologue contralesional area (Jung et al ., ; Kang et al ., ; You et al ., ). Indeed, only after the real stimulation condition, articulatory errors significantly decreased and all patients were faster in repeating the stimuli compared to the sham condition.…”

“…Indeed, after tDCS stimulation most patients were able to correctly produce the whole word and they showed a reduction in phonological errors, the reduction being due to improvement in speech praxis. This is consistent with previous transcranial direct current stimulation–tDCS literature showing longer‐term changes (at 1 month or more) in word retrieval and other language measures (Naeser et al ., , ; Marangolo et al ., , ).…”

“…In recent years, new treatment approaches have emphasised the role of brain stimulation techniques, such as transcranial direct current stimulation (tDCS), as adjuvant strategies to speed up the language recovery process. Indeed, it has been demonstrated that aphasic patients exhibited greater recovery of word‐retrieval deficits if the language treatment was coupled with repeated unihemispheric tDCS stimulation (Baker et al ., ; Fiori et al ., ; Flöel et al ., ; Fridriksson et al ., ; Kang et al ., ; Monti et al ., ; Marangolo et al ., ). In a preliminary study, persistent beneficial effects were found in three chronic aphasic patients after 1 week of intensive language treatment for their apraxia of speech together with 20 min of anodic tDCS stimulation over the left Broca's area (Marangolo et al ., ).…”

Several studies have already shown that transcranial direct current stimulation (tDCS) is a useful tool for enhancing recovery in aphasia. However, all tDCS studies have previously investigated the effects using unihemisperic stimulation. No reports to date have examined the role of bihemispheric tDCS on aphasia recovery. Here, eight aphasic persons with apraxia of speech underwent intensive language therapy in two different conditions: real bihemispheric anodic ipsilesional stimulation over the left Broca's area and cathodic contralesional stimulation over the right homologue of Broca's area, and a sham condition. In both conditions, patients underwent concurrent language therapy for their apraxia of speech. The language treatment lasted 10 days (Monday to Friday, then weekend off, then Monday to Friday). There was a 14-day intersession interval between the real and the sham conditions. In all patients, language measures were collected before (T0), at the end of (T10) and 1 week after the end of (F/U) treatment. Results showed that after simultaneous excitatory stimulation to the left frontal hemisphere and inhibitory stimulation to the right frontal hemisphere regions, patients exhibited a significant recovery not only in terms of better accuracy and speed in articulating the treated stimuli but also in other language tasks (picture description, noun and verb naming, word repetition, word reading) which persisted in the follow-up session. Taken together, these data suggest that bihemispheric anodic ipsilesional and cathodic contralesional stimulation in chronic aphasia patients may affect the treated function, resulting in a positive influence on different language tasks.

Estimulación eléctrica por corriente continua en el tratamiento de la afasia

Introducción. Los ictus son un problema médico con una alta prevalencia en España, y la afasia es una de las secuelas más comunes. Actualmente, la afasia se trata principalmente con terapia neuropsicológica y farmacológica. Sin embargo, en los últimos años, la estimulación eléctrica transcraneal por corriente continua se ha presentado como un complemento a los tratamientos más clásicos. Objetivos. Familiarizar al lector con la estimulación eléctrica transcraneal por corriente continua y revisar de forma crítica los beneficios de esta técnica en la rehabilitación de la afasia. Desarrollo. Tras describir en qué consiste la estimulación eléctrica transcraneal por corriente continua, posteriormente se analizan las evidencias existentes sobre los efectos de esta técnica en el tratamiento de la afasia. Para ello se ha realizado una búsqueda en la base de datos PubMed y se han revisado 19 estudios, publicados entre 2008 y 2016, en los que se utiliza la estimulación eléctrica por corriente continua para el tratamiento de la afasia. Conclusiones. Estos estudios sugieren que la estimulación eléctrica transcraneal por corriente continua es efectiva en el tratamiento de la afasia cuando se acompaña de terapia neuropsicológica. Además, sus beneficios parecen ser mayores cuando se aplica durante al menos cinco sesiones con intensidades superiores a 1 mA, estimulando zonas perilesionales, y en pacientes con afasias fluentes. Los estudios también sugieren que esta técnica no debe entenderse nunca como sustitutiva de la terapia neuropsicológica, sino como una forma de preparar al cerebro para ésta. Palabras clave. Afasia.
