Visual Plasticity Following Brain Lesions

Description

The VIBRANT (Vision Improvement through Behavioral Rehabilitation And Neuroplasticity Training) study is a prospective, double-blind, crossover design (within-subject) in participants with homonymous hemianopia-a type of visual field loss resulting from damage to the post-chiasmatic visual pathways. It aims to investigate whether transcranial random noise stimulation (tRNS) combined with perceptual learning-based training has potential for improving visual impairments.

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.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 1. At least 18 years of age.
  • 2. Capable of providing informed consent and complying with study procedures.
  • 3. Unilateral or bilateral focal brain damage causing loss of vision.
  • 4. At least three months post-stroke or traumatic brain injury, or a stable brain tumor within the past year.
  • 1. Severe CNS diseases or disorders unrelated to the focal lesion, which could interfere with study results.
  • 2. Severe mental health challenges that could interfere with study results, or current or recent (within the past 6 months) drug or alcohol abuse or addiction as defined by DSM-5.
  • 3. Vision loss resulting from ocular disease or disorder.
