Memantine for Executive Dysfunction in Adults With ADHD: A Pilot Study
March 10, 2014 updated by: Joseph Biederman, MD, Massachusetts General Hospital
This is a 12-week clinical trial evaluating the efficacy and safety of memantine hydrochloride (Namenda) in the treatment of executive function deficits (EFDs) in adults with Attention Deficit Hyperactivity Disorder (ADHD) receiving open-label treatment with OROS-Methylphenidate (OROS-MPH, Concerta).
The study aims to examine the effects of treatment with memantine on ADHD symptoms.
Following screening procedures, memantine is prescribed in randomized, double-blind fashion (equal chance of medication or placebo) for 12 weeks, along with open-label OROS-MPH (everyone receives medication).

Participant Group / Arm |
Intervention / Treatment |
---|---|
Placebo Comparator: Placebo
Subjects randomized to receive memantine-matched placebo in addition to open-label OROS-Methylphenidate
|
Memantine-matched placebo will be prescribed following approved FDA dosing guidelines for Alzheimer's dementia, beginning at 5mg in AM and increasing in BID doses by 5mg weekly to a maximum dose of 10mg BID.
OROS-Methylphenidate will be openly prescribed, starting with an initial dose of 36mg/day and titrated to optimal response to a maximum daily dose of 1.3mg/kg or 108mg/day, whichever is lower, according to clinician judgment.
During titration, dose will be increased on a weekly basis in 36mg/day increments.
The dose may be reduced by 18 or 36mg/day increments if adverse effects occur or if the subject discontinues treatment.

Time Frame |
---|---|---|
Percent Change in Global Executive Composite T-Score on the Behavior Rating Inventory of Executive Function-Adult (BRIEF-A)
Time Frame: baseline, 12 weeks
|
This is a 75-item checklist with a large normative sample, internal consistency, test-retest reliability, inter-rater reliability, and external and concurrent validity, divided into nine empirically and theoretically derived and T-scored subscales: Inhibit, Shift, Emotional Control, Self-Monitor, Initiate, Working Memory, Plan/Organize, Task Monitor, and Organization of Materials.
Example item: "I make careless errors when completing tasks."
Items are rated 1 "Never," 2 "Sometimes," or 3 "Often."
The Global Executive Composite (GEC) Score is calculated by totaling all items on the scale.
GEC T-scores range from 34-108, with higher scores indicating more difficulties with executive function.
