A study testing neuroConn_CE_DC-STIMULATOR in people with Traumatic Brain Injury, run by Loewenstein Hospital at 1 site in Israel.
Trial summary
Traumatic brain injury (TBI) particularly affects the frontal lobes and patients often suffer from executive dysfunction and behavioral disturbances.

About this study
Official title: Feasibility of the Use of Electrical Stimulation Using tDCS to Influence Executive Abilities After Traumatic Brain Injury Patients
Traumatic brain injury (TBI) particularly affects the frontal lobes and patients often suffer from executive dysfunction and behavioral disturbances. These types of injuries often involve axonal damage to pre frontal brain areas, which mediate various cognitive and behavioral functions. Dorsolateral prefrontal circuit lesions cause executive dysfunction, orbitofrontal circuit lesions lead to personality changes characterized by disinhibition and anterior cingulate circuit lesions present with apathy. Patients who suffered traumatic frontal lobe damage often demonstrate a lasting, profound disturbance of emotional regulation and social cognition.
Weak transcranial direct current stimulation (tDCS) induces persisting excitability changes in the human motor cortex. this effect depends on the stimulation polarity and is specific to the site of stimulation. Interacting with cortical activity, by means of cortical stimulation, can positively affect the short-term cognitive performance and improve the rehabilitation potential of neurologic patients. In this respect, preliminary evidence suggests that cortical stimulation may play a role in treating aphasia, unilateral neglect, and other cognitive disorders.

Several possible mechanisms can account for the effects of tDCS and other methods on cognitive performance. They all reflect the potential of these methods to improve the subject's ability to relearn or to acquire new strategies for carrying out behavioral tasks. It was also found that Activation of prefrontal cortex by tDCS reduces appetite for risk during ambiguous decision making.
In this tDCS study the investigator uses one anode and one cathode electrode placed over the scalp to modulate a particular area of the central nervous system (CNS). The stimulation is administered via the neuroConn DC.Stimulator Serial number 0096. The DC-STIMULATOR is a micro-processor-controlled constant current source. The DC-STIMULATOR is a CE-certified medical device for conducting non-invasive transcranial direct current stimulation (tDCS) on people.Electrode positioning is determined according to the International EEG 10-20 System.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline MindStreams-NeuroTrax MINDSTREAMS-NEUROTRAX
Computerized tests assess brain wellness across an array of cognitive domains including: memory, executive function, visual spatial perception, verbal function, attention, information processing speed, and motor skills. The psychometric properties of the tests exploit the advantages of computerized testing, providing precise accuracy and reaction time measurements. NeuroTrax offers an unbiased, standardized, accurate and inexpensive tool with a wide range of applicability. The specific tests that will be administered are Go-No Go Response Inhibition and Visual Spatial Processing
Measured: day 1 (twice), day 15, day 21
Secondary outcomes (2)
Change from baseline Behavior Rating Inventory of Executive Function- (Adult Version) BRIEF-A
Measures an adult's views of him- or herself and captures important observer information for a comprehensive picture of the rated individual's executive functioning.
Measured: day 1, day 21
Change from baseline Wechsler Adult Intelligence Scale (WAIS-III )
- The WAIS-III, a subsequent revision of the WAIS and the WAIS-R, was released in 1997. It provided scores for Verbal IQ (Intelligence quotient ), Performance IQ, and Full Scale IQ, along with four secondary indices (Verbal Comprehension, Working Memory, Perceptual Organization, and Processing Speed).
Measured: day 1 (twice), day 15, day 21

Traumatic brain injury (TBI) particularly affects the frontal lobes and patients often suffer from executive dysfunction and behavioral disturbances. These types of injuries often involve axonal damage to pre frontal brain areas, which mediate various cognitive and behavioral functions. Dorsolateral prefrontal circuit lesions cause executive dysfunction, orbitofrontal circuit lesions lead to personality changes characterized by disinhibition and anterior cingulate circuit lesions present with apathy. Patients who suffered traumatic frontal lobe damage often demonstrate a lasting, profound disturbance of emotional regulation and social cognition.

Questions about this trial
What is this clinical trial studying?
A study testing neuroConn_CE_DC-STIMULATOR in people with Traumatic Brain Injury, run by Loewenstein Hospital at 1 site in Israel.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from baseline MindStreams-NeuroTrax MINDSTREAMS-NEUROTRAX (time frame: day 1 (twice), day 15, day 21). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02331615, which also lists 23 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Aug 2018; AzTrials last refreshed its copy on 30 Oct 2026.
