tDCS Effect on Cognitive Functions From Patients With Alzheimer's Disease or Progressive Primary Aphasia (ALSTICO)

October 12, 2017 updated by: Centre Hospitalier Universitaire de Besancon

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

60 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
ACTIVE_COMPARATOR: anodal tDCS on left DLPFC (F3)
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.
Device: transcranial Direct Current Stimulation (tDCS)
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.
Other Names:
  • EldithDC-NeuroConn Stimulator (NeuroConn Gmbh, Germany)
SHAM_COMPARATOR: sham tDCS on left DLPFC (F3)
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.
Device: transcranial Direct Current Stimulation (tDCS)
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.
