A retrospective study of memantine in children and adolescents with pervasive developmental disorders.

RATIONALE: There are no drugs that have been shown to effectively treat the core social impairment of autism. OBJECTIVES: The purpose of this study was to examine the effectiveness and tolerability of memantine for social impairment in children and adolescents with pervasive developmental disorders (PDDs). MATERIALS AND METHODS: Medical records of 18 patients with PDDs consecutively treated with open-label memantine were retrospectively reviewed. The data reviewed included prospectively obtained assessments of severity (S) and improvement (I) using the Clinical Global Impressions Scale (CGI). Pretrial and follow-up parent ratings were also available on six patients using the Aberrant Behavior Checklist (ABC). RESULTS: Eighteen patients (15 male, 3 female; mean age=11.4 years, range 6-19 years) received memantine (mean dosage=10.1 mg/day, range 2.5-20 mg/day) over a mean duration of 19.3 weeks (range 1.5-56 weeks). Eleven of 18 (61%) patients were judged responders to memantine based on a rating of "much improved" or "very much improved" on the CGI-I. Significant improvement was also seen on the CGI-S. Improvement was primarily seen clinically in social withdrawal and inattention. Adverse effects occurred in 7 of 18 (39%) patients and led to drug discontinuation in 4 of 18 (22%) patients. Thirteen of 18 (72%) patients received stable doses of concomitant medications during the memantine trial. CONCLUSIONS: In this open-label retrospective study, memantine was effective in a number of patients with PDDs. Controlled studies are warranted to further assess the efficacy and safety of memantine in PDDs.

Gastrointestinal factors in autistic disorder: a critical review.

Interest in the gastrointestinal (GI) factors of autistic disorder (autism) has developed from descriptions of symptoms such as constipation and diarrhea in autistic children and advanced towards more detailed studies of GI histopathology and treatment modalities. This review attempts to critically and comprehensively analyze the literature as it applies to all aspects of GI factors in autism, including discussion of symptoms, pathology, nutrition, and treatment. While much literature is available on this topic, a dearth of rigorous study was found to validate GI factors specific to children with autism.

Risperidone in pervasive developmental disorders.

Atypical antipsychotics are increasingly used in the treatment of severe behavioral disturbances in people with pervasive developmental disorders. Among these compounds, risperidone has been the most broadly studied. This drug profile will review the available data on the use of risperidone in individuals with pervasive developmental disorders. In addition, the chemistry, pharmacokinetics, pharmacodynamics and metabolism of risperidone are discussed. Emphasis will be placed on adverse effects associated with risperidone in these people, including a discussion of measures that can be taken to monitor for these effects. Finally, a discussion of the future direction of risperidone use in this population and key issues will be presented.

Neurochemistry in the pathophysiology of autism.

Significant progress has been made in the search for underlying pathophysiologic mechanisms in autism over the past 50 years. The cause of the disorder, however, remains largely unknown. This article reviews neurochemical contributions to the pathophysiology of autism with a focus on monoamines, glutamate/gamma-aminobutyric acid systems, and neuropeptides. As these efforts move forward, it will be important to begin to integrate genetic studies with those involving neuroimaging and postmortem research in each of these 3 areas, as well as with pharmacologic treatment approaches.

The use of selective serotonin reuptake inhibitors in autism and related disorders.

This paper reviews the published literature on the use of selective serotonin reuptake inhibitors (SSRIs) for the treatment of symptoms associated with autistic disorder and other pervasive developmental disorders (PDDs) in both children and adults. To date, placebocontrolled studies of SSRIs have involved only fluvoxamine (in children and adults) and fluoxetine (in children). Open-label and retrospective studies of all other SSRIs in PDDs have also been published that suggest effectiveness. Despite these positive reports, there continues to be questions about the tolerability and appropriate dosing of SSRIs in children with PDDs. Because of the limited number of placebo-controlled studies, definitive conclusions about the role SSRIs should play in the clinical treatment of children with PDDs cannot be drawn. Larger, placebo-controlled studies of SSRIs are needed to guide clinical treatment.
