Study Summary

Other psychiatric disorders, including anxiety, often co-occur with adult ADHD; with 85% of ADHD patients having at least one other psychiatric condition. The presence of a co-occurring anxiety disorder has been associated with additive clinical effects, leading to more global impairment, poorer outcome, greater resistance to treatment and increased costs of illness. Stimulants are effective first-line treatments for adult ADHD patients, however the literature has mostly examined these treatments in pure ADHD populations (i.e. without other psychiatric disorders). Thus, there is little information to guide physicians in making treatment decisions for patients with ADHD and a co-occurring condition. This trial aims to evaluate the efficacy and safety of methylphenidate hydrochloride controlled release capsules (Foquest) in treating adults aged 18-65 years with DSM-5 ADHD with and without a co-occurring anxiety disorder.The study uses a 14-week, randomized, placebo-controlled, cross-over design.
