Brain stimulation ‘can aid stroke recovery’

New research has shown the potential benefits non-invasive brain stimulation can provide in aiding recovery among stroke sufferers.

International studies presented at a meeting of cognitive neuroscientists in Chicago this week have shown that transcranial direct current stimulation (tDCS) can have various positive effects on the brain lasting for up to 12 months.

For example, a trial conducted by University College London demonstrated that tDCS treatment can aid the recovery of language skills, while a different set of experiments from the Mackenzie Presbyterian University in Sao Paolo showed it can stimulate better memory retention.

Meanwhile, research from the University of Oxford also showed that the technique can aid people with numeracy problems, suggesting potentially wide-ranging applications.

Roi Cohen Kadosh of the University of Oxford said: "Non-invasive brain stimulation can allow painless, inexpensive and apparently safe method for cognitive improvement with potential long-term efficacy."

Last month, a study from the University Tor Vergata in Rome suggested that patients who enjoy art are more likely to recover quickly following strokes.
