2015, Brain Research BulletinCitation Excerpt :We have shown that stimulation intensity in children might have to be reduced to induce intended effects, since 1 mA cathodal tDCS, which reduces excitability in the adult motor cortex, enhanced it in children, whereas 0.5 mA tDCS resulted in the expected excitability reduction (Moliadze et al., 2015). Several studies demonstrated lower cortical excitability and higher intracortical inhibition in children (Garvey and Mall, 2008) as well as higher pre-activation (Siniatchkin and Gerber, 2002; Siniatchkin et al., 2000). Recent studies which performed current flow modeling in children suggested that a reduced tDCS current intensity is enough to produce the same peak brain electric fields in children compared with adults (Minhas et al., 2012).
Stimulation intensities of transcranial direct current stimulation have to be adjusted in children and adolescents
2015, Clinical NeurophysiologyCitation Excerpt :In disorders with an altered cortical excitability such as migraine, tDCS may induce paradoxical effects: the anodal tDCS may cause a reduction of excitability and the cathodal tDCS opposite changes (Siniatchkin et al., 2012). Several studies demonstrated lower cortical excitability and higher intracortical inhibition in children (note for example higher motor thresholds in children compared with adults, (Garvey and Mall, 2008) as well as higher pre-activation (note higher amplitude of evoked and event-related potentials and lower habituation in children compared with adults (Siniatchkin and Gerber, 2002; Siniatchkin et al., 2000). These developmental characteristics may interfere with effects of tDCS.
