Neurostimulation In Adult Survivors of Childhood Acute Lymphoblastic Leukemia (ALL)

Eligible participants will be randomized to receive 1 mA direct current stimulation over the left dorsolateral prefrontal cortex or placebo/sham for 20 minutes. All participants will receive home-based computerized cognitive training. Participants will complete tDCS paired with cognitive training 2 times per week for 6-months.

Long-term survivors of ALL are at-risk for neurocognitive impairment, particularly in the area of executive functioning. Relatively limited research has focused on interventions for improving neurocognitive outcomes in long-term survivors of ALL. A promising technique for cognitive enhancement is Transcranial Direct Current Stimulation (tDCS) which differs from conventional cognitive remediation approaches in that it directly stimulates specific brain regions responsible for cognitive processes and activates functional networks similar to those activated during cognitive training. Primary Objective To evaluate the efficacy of home-based transcranial direct current stimulation (tDCS) paired with remote cognitive training on direct testing of executive function in survivors of ALL. Secondary Objectives To evaluate the efficacy of home-based transcranial direct current stimulation (tDCS) paired with remote cognitive training on patient-reported symptoms of executive dysfunction in survivors of ALL. To examine the effects of home-based tDCS paired with remote cognitive training on patterns of regional brain activation as measured by functional magnetic resonance imaging. To examine the effects of home-based tDCS paired with remote cognitive training on white matter integrity and structure as measured by diffusion tensor imaging.
