Brief Summary

      Intellectual impairment, particularly working memory deficits are a significant cause of
      morbidity in children with Neurofibromatosis type (NF1) with long-term implications on
      academic and occupational functioning. Whilst significant discoveries have been made in Nf1
      animal models in trying to find treatments for these conditions, human translational studies
      have not been successful. This mechanistic experimental study will investigate the neural
      mechanisms underlying working memory deficits in NF1. In particular, we will investigate how
      individual differences in inhibitory neurotransmitter GABA relate to performance on working
      memory tests. Further, we will investigate the use of a novel, experimental intervention
      called transcranial Direct Current Stimulation (tDCS);known to modulate GABA. Using a
      randomized, crossover design in a cohort of 30 adolescents aged 11-17 years, we will apply
      real or sham tDCS to the dorsolateral prefrontal cortex (DLPFC). State-of-art real time
      imaging techniques such as Magnetic Resonance Spectroscopy (MRS) and task based functional
      MRI (fMRI) will be used to investigate the effect of tDCS on GABA concentration, changes in
      functional plasticity and working memory. We expect that results from this study will help
      elucidate the neural mechanisms underlying working memory deficits in people with NF1 and
      show biologic activity for a novel, low-cost intervention that can be used for cognitive
      remediation in NF1. This kind of focused mechanism trial method is a highly promising
      approach to understanding the complex neural system pathology in a multifactorial
      neurodevelopmental condition like NF1.
