About this study
Official title: Evaluation de l'Effet de la tDCS Sur Les Fonctions Cognitives de Patients Souffrant de Maladie d'Alzheimer et Maladies apparentées au Stade léger
The purpose of this study is to evaluate the effect of 10 sessions of anodal transcranial Direct Current Stimulation (tDCS - 1 mA) applied to left Cortex DorsoLateral PreFrontal (CDLPF) of Alzheimer's or Primary Progressive Aphasia (PPA) patients compared to the application of a placebo tDCS (sham procedure) on cognitive functions, which are evaluated at short term (1 week post-treatment) and mild term (3 weeks post-treatment).
After unblinding, patients who received placebo treatment could be received active tDCS.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
transcranial Direct Current Stimulation (tDCS)Device
Also called EldithDC-NeuroConn Stimulator (NeuroConn Gmbh, Germany)
After locating the stimulation areas, treatment will be delivered during 30-minute session. Treatment will be occur 2 session per day during 5 consecutive days. Subjects will be monitored during tDCS sessions for any side effects or adverse events.
| Study group | Role | What they receive |
|---|---|---|
| anodal tDCS on left DLPFC (F3) | Active comparator | tDCS is a non-invasive neuromodulation method, which delivers a constant current of low intensity (1 mA) during 30 minutes for 10 sessions. Anode is placed on the scalp facing on left DLPFC (F3) and cathode between Fp2-F8 EEG-repair. Receives: Device: transcranial Direct Current Stimulation (tDCS) |
| sham tDCS on left DLPFC (F3) | Sham comparator | Sham tDCS differs from active tDCS by the interruption of stimulation after 15 sec and reactivation of the stimulation 15 sec before the end of the session (30 minutes - 10 sessions. Anode is placed on the scalp facing on left DLPFC (F3) and cathode between Fp2-F8 EEG-repair. Receives: Device: transcranial Direct Current Stimulation (tDCS) |
What is being measured
The primary outcome is the main question the study is designed to answer.
change from baseline cognitive functions at 3 weeks
neuropsychological assessments include Rapid battery tests (Bereay et al., 2015)
Measured: baseline, day 5 and 3 weeks post-tDCS

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to evaluate the effect of 10 sessions of anodal transcranial Direct Current Stimulation (tDCS - 1 mA) applied to left Cortex DorsoLateral PreFrontal (CDLPF) of Alzheimer's or Primary Progressive Aphasia (PPA) patients compared to the application of a placebo tDCS (sham procedure) on cognitive functions, which are evaluated at short term (1 week post-treatment) and mild term (3 weeks post-treatment).
After unblinding, patients who received placebo treatment could be received active tDCS.

Questions about this trial
What is this clinical trial studying?
A study testing transcranial Direct Current Stimulation (tDCS) in people with Alzheimer's Disease and Progressive Primary Aphasia, run by Centre Hospitalier Universitaire de Besancon at 3 sites in France.
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 5 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 13 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in France. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Pierre Vandel, MD PhD (+33381219007, pierre.vandel@univ-fcomte.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
change from baseline cognitive functions at 3 weeks (time frame: baseline, day 5 and 3 weeks post-tDCS). 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 NCT02873546, which also lists 1 linked publication.
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 13 Oct 2017; AzTrials last refreshed its copy on 6 Nov 2026.
