181 Clinical Trials for Various Conditions
This project is a double-blind, sham-controlled, parallel-arm, randomized controlled trial. We will recruit n=170 people living with MS, who are experiencing an episode of depression in the context of a major depressive episode (MDE). Using our remotely supervised (RS) tDCS protocol, enrolled participants will complete 30 days of 30-minute tDCS (2.0, DLPFC left anodal) while listening to mindfulness meditation. Over the course of the study, participants will complete assessments of depression and MS symptoms. Participants will be randomized 1:1 active:sham tDCS.
The purpose of this clinical trial is to investigate the effects of multiple sessions of transcranial direct current stimulation (tDCS) delivered while participants complete tasks that target social learning with high functioning adults with ASD and/or high traits of ASD. The main question it aims to answer is: What are the effects of multiple sessions of active compared to sham tDCS, with tDCS simultaneously paired with social learning tasks, from employing a within-subject, cross-over randomized controlled trial design? Participants will: * Complete a randomly assigned block of 5 sessions of active and a block of 5 sessions of sham tDCS, with a four-week break occurring between the two blocks. * Complete social learning tasks simultaneously during receipt of tDCS at each session (whether receiving active or sham tDCS). * Complete behavioral, physiological, and electrophysiological testing before and after each block of active or sham tDCS. * Complete a social validity questionnaire after completion of the study.
This technology development project will be informed and guided by initial data collection of human subject data. For this purpose, the investigators will recruit n=100 people with mild to moderate depression in a double-blinded, parallel-arm, sham-controlled data collection period administered at home and using the investigator's remotely supervised (RS) tDCS protocol. Enrolled participants will complete 10 days of 30-minute tDCS (2.0, DLPFC left anodal) using the RS-tDCS protocol. During each daily session, standard HR and impedance-based HR (i-HR), obtained from the tDCS headset, will be collected to identify a possible marker of response to tDCS in depression. Participants will be randomized 2:1 to active vs. sham tDCS.
The researchers are trying to test the feasibility and acceptability of using transcranial Direct Current Stimulation (tDCS) in hospitalized adult patients with Treatment Resistant Depression (TRD), assess for any preliminary effect on depressive and cognitive symptoms, and explore the utility of biomarkers to assess response to tDCS.
The purpose of this research study is to investigate the effects of transcranial direct current stimulation (tDCS) on some of the challenges faced by children with Autism Spectrum Disorder (ASD).
The purpose of this study is to establish the feasibility of a program of remotely supervised transcranial direct current stimulation (RS-tDCS) paired with language skills practice for people living with the semantic or logopenic variants of primary progressive aphasia (PPA). There are currently no established standard-of-care treatments for PPA. This study will evaluate whether RS-tDCS combined with language skills practice is a feasible study design for individuals with PPA.
Cognitive impairment refers to when an individual struggles to learn, concentrate, remember, or make decisions. This can be due to underlying neurological diseases (i.e. Alzheimer's disease, dementia, etc.), caused by viral illness (i.e. brain fog experienced by COVID-19 survivors) or physical trauma (i.e. concussion). Recent reports indicate that two out of three Americans experience some amount of cognitive impairment in their lifetime. There are a number of therapies that have been used to help address this condition. One of these is transcranial direct current stimulation (tDCS), which delivers sustained direct current to to the head area via electrodes. A number of studies have indicated that this form of therapy is safe and efficacious at inducing neuroplasticity and exciting neuronal activity. These factors can help improve aspects of cognitive functioning such as working memory, learning, and task performance. The purpose of this pilot study is to examine the acceptability and proof of concept effectiveness of a wireless, transcranial direct current stimulation for people with cognitive impairments.
Significant motor impairments occur in 80% of individuals after moderate to severe stroke and impact the body side to the lesioned hemisphere. Typical motor impairments involve loss of dexterity with highly prevalent upper limb flexion synergy. Advances in treating flexion synergy impairments have been hampered by a lack of precision rehabilitation. Previous studies suggest and support the role of cortico-reticulospinal tract (CRST) hyperexcitability in post-stroke flexion synergy. CRST hyperexcitability is often caused by damage to the corticospinal tract (CST). We hypothesize that: 1) inhibiting the contralesional dorsal premotor cortex (cPMd) will directly reduce the CRST hyperexcitability and thus, reduce the expression of the flexion synergy; 2) facilitating the ipsilesional primary motor cortex (iM1) will improve the excitability of the damaged CST, therefore reducing the CRST hyperexcitability and the flexion synergy. we propose to use a novel targeted high-definition tDCS (THD-tDCS) to specifically modulate the targeted cortical regions for testing his hypothesis, via the following aims: Aim 1. Evaluate the effect of cathodal THD-tDCS over the cPMd on reducing the CRST hyperexcitability and the expression of flexion synergy. Aim 2. Evaluate the effect of anodal THD-tDCS over the iM1 on improving the excitability of the CST, and determine whether this, thus, also reduces the CRST hyperexcitability and the flexion synergy. Aim 3. Evaluate the confluence effect of bilateral THD-tDCS, i.e., simultaneous cathodal stimulation over the cPMd and anodal over the iM1.
The purpose of this study is to assess acceptability, and safety of providing tDCS to ADRD patients with behavioral symptoms and to assess the efficacy of tDCS for ADRD-related symptoms, mainly behavioral symptoms.

This is an open label pilot feasibility telemedicine study. This pilot will involve a total of 37 at-home stimulation sessions (30-minutes each) of multichannel excitatory tDCS targeting the left dorsolateral prefrontal cortex (DLPFC) administered over 8 weeks, with a follow-up period of 4 weeks following the final stimulation session.
The purpose of this research is to understand how a neurostimulation technique, transcranial electrical stimulation (tES), affects brain function in adults with major depression measured with functional magnetic resonance imaging (fMRI). This study targets a specific kind of tES called transcranial direct current stimulation (tDCS), where a mild, constant current is passed between electrodes placed on the scalp.
Reducing pain and recovery of strength and function are major challenges in physical therapy. Transcranial direct current stimulation (tDCS) is a novel intervention that has gained popularity in the rehabilitation of athletic injuries, pain management, and sports performance. Acute application of tDCS has been shown to modulate the perception of effort and fatigue, enhance motor learning, improve endurance performance, and improve muscular power and strength. tDCS has also been shown to reduce pain in patients with chronic pain conditions. Using a double-blind, randomized clinical trial design, we aim to evaluate the effectiveness of tDCS plus standard rehabilitation compared to rehabilitation alone on pain, balance and proprioception, functional performance, and strength following acute ankle inversion sprain. We hypothesize that the group using tDCS will demonstrate superior outcomes in all variables of interest.
The objective of this study is to investigate the short- and long-term effects of multiple sessions of 4 mA M1 tDCS on fatigue and brain activity in recovered COVID-19 patients using established measures of perception of fatigue, performance fatigability, and cerebral glucose uptake. Our central hypothesis is that tDCS will improve fatigue short- and long-term, and thus will improve quality of life (QOL) in recovered COVID-19 patients and that these changes will be associated with alterations in brain activity.
The primary purpose of this research is to gather scientific information about how different people's brains work when they look at different types of pictures. This will help to improve the investigators' understanding of the way the brain works for people who are depressed or anxious, and this knowledge could help lead to better diagnosis and treatment.
In this study, the investigators aim to understand the role of transcranial direct current stimulation (tDCS) in modulating aberrant neurocognitive processes implicated in pediatric patients with obsessive compulsive disorder (OCD).
Noninvasive transcranial direct current stimulation (tDCS) is a low-intensity neuromodulation technique of minimal risk that has been used as an experimental procedure for reducing depressive symptoms and symptoms of other brain disorders. Though tDCS applied to prefrontal brain areas is shown to reduce symptoms in some people with major depressive disorder (MDD), the extent of antidepressant response often differs. Methods that map current flow directly in the brain while a person is receiving tDCS and that determine how functional neuroimaging signal changes after a series of tDCS sessions may help us understand how tDCS works, how it can be optimized, and if it can be used as an effective antidepressant. Investigators will address these questions in a two-part randomized double blind exploratory clinical trial. For this part of the study, investigators will determine relationships between target engagement and clinical outcomes (mood) and functional sub-constructs of cognitive control and emotion negativity bias, and whether imaging markers at baseline predict changes in antidepressant response. One hundred people with depression (50 in each group) will be randomized to receive either HD-tDCS or sham-tDCS for a total of 12 sessions each lasting 20 minutes occurring on consecutive weekdays. At the first and last session, subjects will receive 20-30 minutes of active or sham HD-tDCS in the MRI scanner, which will allow investigators to map tDCS currents, and track changes in regional cerebral blood flow (rCBF) pre-to- post treatment using completely non-invasive methods. At the first and last session and mid-way through the trial, participants will also complete a series of clinical ratings and neurocognitive tests.

This study will investigate the effects of mild electrical stimulation in conjunction with speech therapy for people with post-stroke aphasia to enhance language recovery.
The purpose of this study is to assess changes in language abilities of participants with chronic, post-stroke aphasia following an 8-week therapy period combined with brain stimulation. The investigators use a stimulation method called transcranial direct current stimulation (tDCS). The investigators cover two electrodes in damp sponges, place them on the scalp, and pass a weak electrical current between them. Some of this current passes through the brain and can change brain activity. One electrode is placed over language areas a bit above and in front of the left ear. The other is placed on the forehead above the right eye. Stimulation is provided twice a week for 8 weeks during aphasia therapy. The investigators believe that this stimulation may increase the effectiveness of therapy.
Aphasia is an acquired (typically left-hemisphere) multi-modality disturbance of language that impacts around 2 million people in the USA. Aphasia impacts language production and comprehension as well as reading and writing. The ramifications of aphasia extend beyond language impairment to negatively impacting a person's social, vocational, and recreational activities. Currently, the most effective way to treat aphasia is with speech-language therapy (SLT). However, even if SLT is intensive, persons with aphasia are left with residual language delays. Recent research suggests that pairing SLT with transcranial direct current stimulation (tDCS) a non-invasive, safe, low-cost form of brain stimulation may aid language recovery in persons with aphasia. However, results from tDCS studies are inconclusive. The success of tDCS in combination with SLT could depend on the timing of tDCS since tDCS-induced effects depend on the neuronal state of the brain-networks at the time of the stimulation. In this study, the differential impact of tDCS before behavioral SLT (offline-before therapy), tDCS after SLT (offline-after therapy), and tDCS concurrently with SLT (online) on functional language recovery in persons with aphasia will be investigated. Sham tDCS (i.e., SLT alone) as a control group will also be included in the study. The investigators hypothesize that both offline and online tDCS will improve language functioning than sham tDCS.
This study is aimed to test the efficacy of transcranial direct current stimulation (tDCS) combined with a physical activity (PA) program, in 80 individuals affected by Multiple Sclerosis (MS). In particular, this study will evaluate the efficacy of tDCS when administered simultaneously with PA on walking, functional mobility, and fatigue. The subjects enrolled will be randomly assigned to the active group (active tDCS+PA) or the sham group (sham tDCS+PA). Portions of this study may be completed remotely.
Intensive therapy for aphasia has been demonstrated to improve language functioning after stroke or other neurological injury. However, recovery is generally not complete and new therapies are needed to improve outcomes. Transcranial direct current stimulation (tDCS) has been shown to improve outcomes with motor therapy after stroke. This study will examine the feasibility of using tDCS with intensive language therapy as a way of enhancing language outcomes in aphasia
This research is being done to determine whether transcranial direct current stimulation (tDCS) can improve fatigue and certain thinking skills in women with breast cancer receiving chemotherapy. Transcranial Direct Current Stimulation is a form of brain stimulation during which low amounts of electrical current are delivered to the brain using electrodes attached to the scalp. The idea of using electrical stimulation to affect neurological symptoms has been around for more than 100 years with the first reported use in 1801. Since the 1960s, tDCS has been used in research for a variety of reasons including stroke rehabilitation, memory enhancement and for depression. People aged 18 or older who are currently receiving chemotherapy with docetaxel and who are experiencing fatigue may join.
This is a 4 week therapeutic pilot study with a 4 week follow-up period involving inpatients with treatment resistant DSM-IV schizophrenia or schizoaffective disorder diagnosis. Each eligible subject will receive either 20 minutes of active tDCS (transcranial direct-current stimulation) or sham stimulation twice a day on 5 consecutive weekdays for 4 weeks with a 4 week follow-up period.
The overall objective of this study is to explore whether transcranial Direct Current Stimulation (tDCS) can accelerate associative learning and boost associative memory in healthy subjects.
