Abstract:

HD-tDCS is a new non-invasive brain stimulation method that improves current focality and intensity. In this study, the aim was to report a patient with intellectual disability and refractory focal epilepsy who participated in HD-tDCS intervention for his seizure control and assessing the quality of cognitive function variation. Five days LTM evaluation results show that there was a distinct focal epileptogenic lesion in the C4. We recorded EEG and used IVA+test in three steps; before the HD-tDCS sessions (10 sessions), at the end of the last stimulation and one month after. Attention performance showed little improvement in scores with regard to the IVA+test. The EEG studies showed a short-term benefit in reducing the generalized epilepsy severity. However, this effect did not last up to a one-month evaluation. More studies needed to be done in this area.
