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

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.

Detailed Description

Cognitive impairment following moderate to severe traumatic brain injury are usual. To date, cognitive rehabilitation effects on cerebral plasticity and quality of life remain unproven essentially because of methodological biases. Transcranial Direct Current Stimulation is an innovative technique of noninvasive brain stimulation that showed efficacy in literature. The current study want to better understand cerebral plasticity mechanisms to optimize non-pharmacological rehabilitation approaches for patients with traumatic brain injury. The aim in the present study is to assess the effect of rehabilitation combined with Transcranial Direct Current Stimulation provided to traumatic brain injury patients with cognitive impairment on cerebral plasticity using functional magnetic resonance imaging. Effects of rehabilitation and Transcranial Direct Current Stimulation will be observed on functional magnetic resonance imaging activation maps acquired. Relationship between attentional outcomes measured in the neuropsychological assessment and activation extend will be explored.

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.
