Abstract

Objective: High-definition transcranial direct current stimulation (HD-tDCS) has the potential to improve cognitive functioning following neurological injury and in neurodegenerative conditions. In this case report, we present the first use of HD-tDCS in a person with severe anterograde amnesia following carbon monoxide poisoning.

Method: The participant underwent two rounds of HD-tDCS that were separated by 3 months (Round 1 = 30 sessions; Round 2 = 31 sessions). We used finite element modeling of the participant's structural MRI to develop an individualized montage that targeted multiple brain regions involved in memory encoding, as identified by Neurosynth.

Results: Overall, the participant's objective cognitive functioning improved significantly following Round 1, declined during the 2 months without HD-tDCS, and again improved following Round 2. Subjective informant reports from family and medical personnel followed this same pattern of improvement following each round with a decline in between rounds. We also provide preliminary evidence of altered brain activity during a learning/memory task using functional near-infrared spectroscopy, which may help establish the physiological effects of HD-tDCS in future work.

Conclusion: Overall, these findings reinforce the potential value of HD-tDCS as a user-friendly method of enhancing cognition following anoxic/hypoxic brain injury.

期刊介绍: The Journal of the International Neuropsychological Society is the official journal of the International Neuropsychological Society, an organization of over 4,500 international members from a variety of disciplines. The Journal of the International Neuropsychological Society welcomes original, creative, high quality research papers covering all areas of neuropsychology. The focus of articles may be primarily experimental, applied, or clinical. Contributions will broadly reflect the interest of all areas of neuropsychology, including but not limited to: development of cognitive processes, brain-behavior relationships, adult and pediatric neuropsychology, neurobehavioral syndromes (such as aphasia or apraxia), and the interfaces of neuropsychology with related areas such as behavioral neurology, neuropsychiatry, genetics, and cognitive neuroscience. Papers that utilize behavioral, neuroimaging, and electrophysiological measures are appropriate. To assure maximum flexibility and to promote diverse mechanisms of scholarly communication, the following formats are available in addition to a Regular Research Article: Brief Communication is a shorter research article; Rapid Communication is intended for "fast breaking" new work that does not yet justify a full length article and is placed on a fast review track; Case Report is a theoretically important and unique case study; Critical Review and Short Review are thoughtful considerations of topics of importance to neuropsychology and include meta-analyses; Dialogue provides a forum for publishing two distinct positions on controversial issues in a point-counterpoint format; Special Issue and Special Section consist of several articles linked thematically; Letter to the Editor responds to recent articles published in the Journal of the International Neuropsychological Society; and Book Review, which is considered but is no longer solicited.
