The primary outcome measures were changes in the speed and accuracy of information processing during neurocognitive testing using the computer-assisted CogScreen-Aeromedical Edition test, which measures working memory, information processing speed, mental flexibility, and other parameters.Īt study week 3, accuracy scores on a visual-spatial working memory test were higher in the treatment group than the placebo group (95% vs 93% P =.
The treatment group received 20 mg mixed amphetamine salts XR daily in the first week, 40 mg/day in the second week, and 50 mg/day in the third week. In a recent study, 15 adults aged 19 to 25 with ADHD were randomized to receive mixed amphetamine salts XR or placebo for 3 weeks and were then crossed over to the other group for another 3 weeks. Analysis of the National Comorbidity Replication Survey revealed that 3% of a nationally representative sample of 10,000 US adults satisfied diagnostic criteria for ADHD, and that more than one third of those diagnosed with ADHD had not been diagnosed until adulthood. Once thought to be primarily a disorder of childhood, ADHD is now known to frequently extend into adolescence and adulthood. TORONTO, Canada-Treatment with mixed amphetamine salts extended release (XR) (Adderall XR) improves information processing speed and accuracy in adults with attention-deficit/hyperactivity disorder (ADHD), according to findings presented at the annual meeting of the American Psychiatric Association.
