About this trial

This is an interventional diagnostic trial for Attention Deficit Hyperactivity Disorder focused on measuring ADHD, Adults, Electroencephalography (EEG), Concerta

Eligibility Criteria

18 Years - 55 Years (Adult)All SexesAccepts Healthy Volunteers

ADHD Subjects

Inclusion Criteria:

  • Male and female outpatients, aged 18-55 years
  • Subjects meeting full criteria for the diagnosis of DSM-IV (Diagnostic and Statistical Manual, Version 4) Attention Deficit Hyperactivity Disorder (ADHD)
  • Absence of pharmacological treatment for ADHD for at least one week.
  • Right handedness

Exclusion Criteria:

  • Any other current psychiatric or medical condition determined to be clinically significant.
  • Current use of psychotropics or any medication with clinically significant CNS (Central Nervous System) effects.
  • Mental retardation (IQ < 80).
  • Significant sensory deficits such as deafness or blindness.
  • Individuals with a history of substance dependence or abuse within the past 6 months.
  • Pregnant or nursing females.
  • Subjects with pre-existing structural cardiac abnormalities.
  • Clinically significant abnormal laboratory values, electrocardiogram or blood pressure reading

Healthy Control Subjects

Inclusion Criteria:

  • Males and females, aged 18-55 years
  • Subjects who do not meet full criteria for the diagnosis of DSM-IV Attention Deficit Hyperactivity Disorder (ADHD), as determined by clinical evaluation and/or ADHD module of structured diagnostic interview, completed by the study clinician.
  • Right handedness

Exclusion Criteria:

  • Any current psychiatric or medical condition determined to be clinically significant.
  • Current use of psychotropics or any medication with clinically significant CNS effects.
  • Mental retardation (IQ < 80).
  • Significant sensory deficits such as deafness or blindness.

Concerta

Control group

Arm Description

Open-Label Concerta (Osmotic Release Methylphenidate)

Healthy subjects without ADHD will be assessed using EEG.

Outcomes

Primary Outcome Measures

Adult ADHD Investigator Symptom Rating Scale (AISRS)
An 18-item scale rating a subject's level of impairment from 0 (none) to 3 (severe) for each symptom of DSM-IV ADHD, with a maximum possible score of 54. The measure was collected at Baseline and 6 weeks, and a total score was calculated to gauge treatment response of ADHD subjects to open-label Concerta.
Percent Errors in Visual Go/NoGo Task
The Go/NoGo visual task was completed by subjects with ADHD as well as healthy controls. The Go/NoGo task is used to assess inhibitory control, and targets response inhibition, executive functions, and sustained attention. The 'Go' stimulus occupies 80% of the trials, and requires the subject to perform a motor response each time it appears on the screen. A rare 'No Go' stimulus (occupies 20% of all trials) requires the subject to refrain from responding. The percentage of errors were measured for each group.

5. Study Description

Brief Summary
The purpose of this research study is to study a device called an electroencephalograph (EEG) in the diagnosis of treatment of attention deficit hyperactivity disorder (ADHD) in adults. People with ADHD have symptoms such as difficulty sustaining attention, organizing, and managing impulsivity. They can have trouble in school, at work, and at home. Subjects with ADHD who participate in this study will be given a once daily stimulant medication called osmotic release methylphenidate (Concerta) for 6 weeks, and have EEG testing done before and after the treatment period. Subjects will perform a computer based cognitive task during EEG testing. The U.S. Food and Drug Administration has approved osmotic release methylphenidate (Concerta) for the treatment of ADHD in adults and children. Similar procedures, without medication, will be performed with a sample of healthy adults without ADHD.

Intervention Description
During a 6 week treatment period, adult subjects with ADHD are prescribed, in an open label fashion, once daily doses of osmotic release methylphenidate to a maximum daily dose of 144 mg. Efficacy and tolerability assessments are completed, in addition to EEG and cognitive testing. Healthy adults without ADHD will not receive medication.
