Brief Summary: The purpose of this randomized withdrawal study is to evaluate the safety, tolerability, and efficacy of memantine compared with placebo in pediatric patients with autism, Asperger's Disorder, or Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS).

Every effort should be made to maintain the same caregiver as used in the lead-in study throughout this study
5. Have normal results from the physical examination, laboratory tests, ECG, and vital signs at Visit 1 of this study (last visit of Study MEM-MD-91). Any abnormal findings must be deemed not clinically significant by the Investigator and documented
6. Be able to speak and understand English sufficiently (or their native language if this can be accommodated by the site), as well as have a caregiver and parent/guardian/LAR who is able to speak and understand English sufficiently (or their native language if this can be accommodated by the site), to comprehend the nature of the study and to allow for the completion of all study assessments
7. Have a family that is sufficiently organized and stable to guarantee adequate safety monitoring and continuous attendance to clinic visits for the duration of the study
