The purpose of this study is to assess vitamin D as a therapeutic adjunct in the stimulant treatment of ADHD.


Clinical Trial Description

The specific aim of this study is to determine whether acute calcitriol (vitaminD) administration (compared to placebo) enhances the neurocognitive effects of of current stimulant medications as measured by tasks of vigilance/attention, spatial working memory, and reversal learning in individuals with (attention deficit hyperactivity disorder (ADHD) using a randomized, double-blind, placebo controlled, within-subject, two-day study design. Primary Hypothesis: It is hypothesized that calcitriol (versus placebo) administration will enhance positive neurocognitive effects of current stimulant medications in individuals with ADHD. Secondary (Exploratory) Hypothesis: It is hypothesized that calcitriol (versus placebo) administration alone will also enhance neurocognitive performance on tasks of attention/vigilance and/or spatial working memory. ;
