About this study

Official title: Effects of Transcranial Direct Current Stimulation on the Apathy of Alzheimer's: a Randomized, Sham-controlled Clinical Trial

This is a phase 2 double-blind, randomized, sham-controlled study to investigate the effects of repeated transcranial direct current stimulation for the treatment of apathy in moderate Alzheimer's Disease in patients selected from an outpatient clinics in São Paulo, Brazil.

Read the detailed description

Forty patients were randomized to receive either active or sham-tDCS over the left dorsolateral prefrontal cortex (DLPFC). Patients received six sessions of intervention during two weeks and were evaluated at baseline, at week one and two, and after one week without intervention. Clinical raters, patients, and caregivers were blinded. The primary outcome was apathy. Global cognition and neuropsychiatric symptoms were examined as secondary outcomes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Apathy Symptoms

    Apathy evaluated by Apathy Scale by Starsktein et al, 1992, which consists of 14 items phrased as questions that are to be answered by the caregiver on a four-point Likert scale. The total score range from 0 to 42, with higher scores indicating greater apathy severity. Apathy was assessed at baseline and at the end of the sixth session (second week).

    Measured: Differences in outcome measure comparing second week to baseline

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Transcranial direct current stimulation in people with Apathy and Alzheimer's Disease, run by University of Sao Paulo at 1 site in Brazil.

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 4 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 Jan 2014. 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 Brazil. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 Jan 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Apathy Symptoms (time frame: Differences in outcome measure comparing second week to baseline). 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 NCT01481558, 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 9 Jan 2014.
