Memantine (Namenda) is a low-affinity N-methyl-D-aspartate (NMDA) receptor antagonist believed to work by blocking prolonged low-level activation of the NMDA receptor and resultant neuronal damage caused by abnormal glutamatergic activity, yet also allowing normal physiological activity of the NMDA channel. Memantine (Namenda) was approved by the U.S. Food and Drug Administration in 2003 for the treatment of moderate to severe Alzheimer's disease. Memantine improves or delays the decline in cognition (attention, language, visuo-spatial ability), as well as functional and behavioral symptoms in adults with moderate Alzheimer's disease.
Although the efficacy and safety of memantine has not been tested in people with ADHD, the spectrum of disorders possibly amenable to NMDA receptor antagonist treatment may include ADHD and associated executive function deficits (EFDs). To this end, we are proposing an open-label pilot study of memantine in adult subjects with ADHD and ADHD Not Otherwise Specified (NOS).
This will be a 12-week, open-label pilot study to assess the efficacy and tolerability of memantine hydrochloride (Namenda) administered to 20 adults 18-55 years of age with ADHD and ADHD NOS. All subjects that enter the study will undergo standard screening and diagnostic procedures. After obtaining written informed consent from the subject, the diagnosis of ADHD will be established through clinical evaluation by an expert clinician. Only consenting subjects satisfying inclusion and exclusion criteria will be included in the study.

Other Name: Namenda
- DSM-IV ADHD Rating Scale (AISRS) Score Change [ Time Frame: Endpoint, following 12 weeks Memantine Monotherapy ]
AISRS used to assess 18 individual criteria symptoms of ADHD in DSM-IV on a severity grid (0=not present, 3=severe; minimum score=0, maximum score=54). This is a composite score assessing both inattention and hyperactivity, which are not assessed individually in this scale.
Score change from baseline.
