BACKGROUND:Transcranial direct current stimulation (tDCS) is a method of noninvasive neuromodulation and potential therapeutic tool to improve functioning and relieve symptoms across a range of central and peripheral nervous system conditions. Evidence suggests that the effects of tDCS are cumulative with consecutive daily applications needed to achieve clinically meaningful effects. Therefore, there is growing interest in delivering tDCS away from the clinic or research facility, usually at home. OBJECTIVE:To provide a comprehensive guide to operationalize safe and responsible use of tDCS in home settings for both investigative and clinical use. METHODS:Providing treatment at home can improve access and compliance by decreasing the burden of time and travel for patients and their caregivers, as well as to reach those in remote locations and/or living with more advanced disabilities. RESULTS:To date, methodological approaches for at-home tDCS delivery have varied. After implementing the first basic guidelines for at-home tDCS in clinical trials, this work describes a comprehensive guide for facilitating safe and responsible use of tDCS in home settings enabling access for repeated administration over time. CONCLUSION/CONCLUSIONS:These guidelines provide a reference and standard for practice when employing the use of tDCS outside of the clinic setting.

INTRODUCTION/BACKGROUND:To demonstrate the broad utility of the remotely supervised transcranial direct current stimulation (RS-tDCS) protocol developed to deliver at-home rehabilitation for individuals with multiple sclerosis (MS). METHODS:Stimulation delivered with the RS-tDCS protocol and paired with adaptive cognitive training was delivered to three different study groups of MS patients to determine the feasibility and tolerability of the protocol. The three studies each used consecutively increasing amounts of stimulation amperage (1.5, 2.0, and 2.5 mA, respectively) and session numbers (10, 20, and 40 sessions, respectively). RESULTS:High feasibility and tolerability of the stimulation were observed for n = 99 participants across three tDCS pilot studies. CONCLUSIONS:RS-tDCS is feasible and tolerable for MS participants. The RS-tDCS protocol can be used to reach those in locations without clinic access and be paired with training or rehabilitation in locations away from the clinic. This protocol could be used to deliver tDCS paired with training or rehabilitation activities remotely to service members and veterans.

Pediatric multiple sclerosis (MS) is an increasingly recognized rare subgroup of patients presenting with a unique set of diagnostic challenges. Understanding the early development of MS may offer a window into the pathogenesis of disease; however further research is needed, particularly within the field of genetics and to understand the complex environmental and biological interactions at work. Acute disseminated encephalomyelitis (ADEM) remains a hallmark presentation of early pediatric disease and can be a monophasic illness or end up being reclassified as a relapsing disorder. The clinical expression is shaped in part by the prepubertal or postpubertal state of the patient. Other syndromes can also present with ADEM, and a specific differential diagnosis exists for children presenting with any initial demyelinating event (IDE). New definitions and criteria have allowed early detection of MS. However applying adult criteria to very young children should be approached with caution. There is now a major effort in studying disease-modifying therapy (DMT) in children due to requirements from regulatory authorities. Pediatric patients respond well to therapy and often do best with an interdisciplinary approach focusing on social aspects, cognition, and fatigue which enhances the achievement of successful outcomes.
