Attention-Deficit/Hyperactivity Disorder (ADHD)

ADHD is a developmental disorder associated with an ongoing pattern of inattention, hyperactivity, and/or impulsivity. Symptoms of ADHD can interfere with daily activities and relationships. Although the symptoms typically appear in childhood, ADHD can continue through adolescence and adulthood. Learn more about attention-deficit/hyperactivity disorder (ADHD).

SKIP for PA Study: Team and Leadership Level Implementation Support for Collaborative Care

Study Type: Interventional
Start Date: November 29, 2021
Location: Pittsburgh, Pennsylvania, United States
Eligibility: Ages 18 and Older, Does Not Accept Healthy Volunteers

In a prior application (MH064372), the investigators' treatment research program (Services for Kids In Primary-care, SKIP) developed and tested a chronic care model-based intervention, called Doctor Office Collaborative Care (DOCC), that was found to be effective in the management of childhood behavior problems and comorbid ADHD. In the "SKIP for PA Study", the investigators propose to conduct a randomized clinical trial to evaluate the effects of team- and practice leadership-level implementation strategies designed to enhance the use and uptake of DOCC in diverse pediatric primary care offices.

Brain Imaging of Childhood Onset Psychiatric Disorders, Endocrine Disorders and Healthy Volunteers

Study Type: Observational
Start Date: June 19, 1990
Location: Bethesda, Maryland, United States
Eligibility: Ages 3 and Older, Accepts Healthy Volunteers

Magnetic Resonance Imaging (MRI) unlike X-rays and CT-scans does not use radiation to create a picture. MRI use as the name implies, magnetism to create pictures with excellent anatomical resolution. Functional MRIs are diagnostic tests that allow doctors to not only view anatomy, but physiology and function. It is for these reasons that MRIs are excellent methods for studying the brain. In this study, researchers will use MRI to assess brain anatomy and function in X and Y chromosome variation, healthy volunteers, and patients with a variety of childhood onset psychiatric disorders. The disorders include attention deficit disorder, autism, congenital adrenal hyperplasia, childhood-onset schizophrenia, dyslexia, obsessive compulsive disorder, Sydenham's chorea, and Tourette's syndrome. Results of the MRIs showing the anatomy of the brain and brain function will be compared across age, sex (gender), and diagnostic groups. Correlations between brain and behavioral measures will be examined for normal and clinical populations.

Pilot Testing PREschooler Care, Community Resources, Advocacy, Referral, Education (PRE-CARE)

Study Type: Interventional
Start Date: November 30, 2021
Location: Boston, Massachusetts, United States
Eligibility: Ages 16 and Older, Accepts Healthy Volunteers

The goal of this proposed study is to pilot test a novel treatment model (PRE-CARE) addressing unmet social needs for families of preschool-age children with Attention Deficit/Hyperactivity Disorder (ADHD) symptoms. The investigators will conduct an adaptive, pilot randomized controlled trial (RCT) of the intervention with parents of 60 low-income children age 3-5 (36-71 months) with ADHD symptoms in order to: optimize intervention delivery; field test study logistics (e.g., recruitment, enrollment, randomization, retention); explore putative intervention mechanisms; and obtain estimates of study parameters to plan an appropriately powered RCT of the intervention. The PRE-CARE intervention is adapted from Well Child Care, Evaluation, Community, Resources, Advocacy, Referral, Education (WE CARE), a screening and referral intervention that has been shown to be feasible and effective in addressing the family psychosocial stressors of low-income families seen in pediatric medical homes. Given the negative impact that socioeconomic stressors can have on the health and development of young children with ADHD symptoms, tailored interventions such as PRE-CARE may serve as a vital early intervention strategy to promote long-term well-being.

Brain Plasticity Underlying Acquisition of New Organizational Skills in Children

Study Type: Interventional
Start Date: October 01, 2019
Location: New York, New York, United States
Eligibility: Ages 8-12, Does Not Accept Healthy Volunteers

Organizational, time management and planning (OTMP) skills deficits are impairing features of developmental disorders, such as Attention Deficit Hyperactive Disorder (ADHD), which compromise school performance and family relations. The manualized Organizational Skills Training program (OST) was designed to target children's specific OTMP deficits. However, the brain mechanisms of treatment-induced changes remain unknown. The current study combines a training intervention (OST) with non-invasive MRI imaging in a pre-/post-design in a randomized two-arm (treatment vs. waitlist) trial to address this question.

A Novel fNIRS Neurofeedback Intervention for Enhancement of Working Memory in Attention Deficit Hyperactivity Disorder (ADHD)

Study Type: Interventional
Start Date: August 16, 2019
Location: Stanford, California, United States
Eligibility: Ages 7-11, Does Not Accept Healthy Volunteers

The proposed study is to test and validate a novel intervention that integrates computerized cognitive training with real-time neuromonitoring and neurofeedback to enhance working memory by probing the individualized neural systems underlying working memory. We will test the proposed intervention on children with ADHD with working memory deficits. The R61 proof-of-concept phase will assess the target engagement, effective dose and feasibility.
