What is being measured
The primary outcome is the main question the study is designed to answer.
performance in LOCATO task (visual-spatial learning and memory) after a combination of intensive visual-spatial training and tDCS
Investigation whether the combination of intensive visual-spatial training (LOCATO task) and tDCS leads to improvement of visual-spatial learning and memory measured by the performance in LOCATO task after end of a 3 day period of training compared to sham stimulation.
Measured: immediately after end of a 3 day period of training in tDCS condition vs sham condition
Secondary outcomes (6)
long term effects
long term effetcs measured by performance in LOCATO task after end of training and after 1 month compared to control conditions
Measured: after 1 month vs baseline
functional changes: Connectivity
Connectivity (measured by resting-state fMRT and correlation analysis) at baseline compared to end of training
Measured: after end of 3-day cognitive training vs baseline
cortical excitability
cortical excitability measured by transcranial magnetic stimulation (TMS)
Measured: at baseline
Quality of Life
quality of life as measured by standardized questionaire at baseline compared to quality of life measured 1 month after intervention (training and stimulation vs. training and sham-stimualtion)
Measured: after 1 month vs baseline
memory
memory performance tested at baseline compared to memory performance after the end of a 3-day cognitive training period and after 1 month (posttraining) in training and stimulation vs. training and sham stimulation
Measured: immediately after end of 3-day of cognitive training, after 1 month vs. baseline
genotyping of learning related polymorphisms
To assess predictors of positive reaction to brain stimulation, genotyping of several learning related polymorphisms will be performed (i.e., APOE, BDNF Val66Met, COMT Val158Met).
Measured: once

Questions about this trial
What is this clinical trial studying?
A study testing tDCS and training in people with Healthy Young Adults, run by Charite University, Berlin, Germany at 1 site in Germany.
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 3 inclusion and 5 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 27 Jul 2017. 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 Germany. 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?
performance in LOCATO task (visual-spatial learning and memory) after a combination of intensive visual-spatial training and tDCS (time frame: immediately after end of a 3 day period of training in tDCS condition vs sham condition). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 27 Jul 2017.
