ADHD With Working Memory Deficits Clinical Trial
Official title:
rTMS and Executive Functioning Training for Working Memory Deficits in Adolescent Psychopathology
Executive functioning (EF) deficits are a core, transdiagnostic feature of psychopathology and one of the strongest predictors of clinical and functional outcomes, yet there remains a dearth of treatments available for EF deficits. EF is a collection of cognitive control processes that includes working memory (i.e., maintain/manipulate data not perceptually present), inhibition (i.e., inhibit/control of attention, thoughts, behaviors) and flexibility (i.e., shift flexibly between tasks/sets). These EF subdomains are subserved by a network (i.e., cognitive control network) of frontal (e.g., dorsolateral prefrontal cortex [DLPFC]), parietal and subcortical regions, with hypoactivation in such regions often underlying EF deficits. There is a recent call in psychiatry to develop experimental therapeutics that target anomalous neural systems underlying symptomology. Repetitive transcranial magnetic stimulation (rTMS) is a therapeutic, non-invasive method of cortical excitability modulation. High frequency rTMS to the left DPLFC has an activating effect on the cognitive control network, with initial research in adults finding a subsequent enhancing effect on working memory, inhibition, and flexibility. rTMS represents a very promising potential tool to target EF deficits in psychopathology.
