Gentle brain zaps may help stroke survivors regain spatial awareness

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Hemorrhagic or ischemic stroke in the right hemisphere. * Stroke 3 to 12 months since the event (regardless of whether or not they have received prior rehabilitation). * 18 to 99 years-old. * Neuroimaging study. * Absence of previous strokes. * Functional capacity that allows him/her to remain seated and active for one hour (Barthel Index score greater than 5 in the item of transfers between chair and bed; this item can be scored from 0 to 15, being 0 totally dependent and 15 totally independent). * Right-handed manual dominance * Neglect scores on at least two of the three tests administered for the assessment of visuospatial neglect. * Signature of informed consent by the patient or his/her legal guardian. Exclusion Criteria: * Dermatological problems (psoriasis, dermatitis on the scalp or face). * Presence of implants or metal parts in the head excluding fillings. * Pacemakers, medication pumps, stimulators (vagal, cerebral, transcutaneous), ventriculoperitoneal shunts or aneurysm clips. * Presence of previous strokes. * Neurological disease other than stroke described in the inclusion criteria. * Severe cognitive impairment assessed using the Mini-mental state examination (MMSE), excluding patients with scores under 24 (the score of MMSE are between 0 and 30, being 0 severe cognitive impairment and 30 no cognitive impairment). * Significant language difficulties that not allow proper understanding of activities or severely limit expression. * History of alcohol or drug abuse. * Moderate or severe active depression. * Uncontrolled medical problems (pathologies in acute phase without medical or pharmacological treatment with proven efficacy or pathologies with imminent life risk). * Pregnancy or suspected pregnancy that will be checked by pregnancy test at the beginning of the study in patients of childbearing age and with the recommendation of the use of contraceptive methods until the end of the intervention.
