    RECENT PUBLICATIONS

    Maternal periconceptional folic acid intake and risk of autism spectrum disorders and developmental delay in the CHARGE (CHildhood Autism Risks from Genetics and Environment) case-control study (Schmidt et al., 2012; University of California Davis).

    Periconceptional folate is essential for proper neurodevelopment. Maternal folic acid intake was examined in relation to the risk of autism spectrum disorder (ASD) and developmental delay (DD). Families enrolled in the CHARGE (CHildhood Autism Risks from Genetics and Environment) Study from 2003 to 2009 were included if their child had a diagnosis of ASD (n = 429), DD (n = 130), or typical development (TD; n = 278) confirmed at the University of California Davis Medical Investigation of Neurodevelopmental Disorders Institute by using standardized clinical assessments. Average daily folic acid was quantified for each mother on the basis of dose, brands, and intake frequency of vitamins, supplements, and breakfast cereals reported through structured telephone interviews. Mean (±SEM) folic acid intake was significantly greater for mothers of TD children than for mothers of children with ASD in the first month of pregnancy (P1; 779.0 ± 36.1 and 655.0 ± 28.7 μg, respectively; P < 0.01). A mean daily folic acid intake of > 600 μg (compared with < 600 μg) during P1 was associated with reduced ASD risk (adjusted OR: 0.62; 95% CI: 0.42, 0.92; P = 0.02), and risk estimates decreased with increased folic acid (P-trend = 0.001). The association between folic acid and reduced ASD risk was strongest for mothers and children with MTHFR 677 C>T variant genotypes. A trend toward an association between lower maternal folic acid intake during the 3 months before pregnancy and DD was observed, but not after adjustment for confounders. In summary, periconceptional folic acid may reduce ASD risk in those with inefficient folate metabolism. The replication of these findings and investigations of mechanisms involved are warranted.


    Moderators, mediators, and other predictors of risperidone response in children with autistic disorder and irritability (Arnold et al., 2010; Ohio State University).

    The National Institute of Mental Health (NIMH) Research Units on Pediatric Psychopharmacology (RUPP) Autism Network found a large effect size (d=1.2) in favor of risperidone on the main outcome measure in an 8-week double-blind, placebo-controlled trial for irritability in autistic disorder. This paper explores predictors of response including moderators and mediators of this effect. Intention-to-treat (ITT) analyses were conducted with suspected moderators and mediators entered into the regression equations. MacArthur Foundation Network subgroup guidelines were followed in the evaluation of the results. Only baseline severity moderated treatment response: Higher severity showed greater improvement for risperidone but not for placebo. Weight gain mediated treatment response negatively: Those who gained more weight improved less with risperidone and more with placebo. Compliance correlated with outcome for risperidone but not placebo. Higher dose correlated with worse outcome for placebo, but not risperidone. Of nonspecific predictors, parent education, family income, and low baseline prolactin positively predicted outcome; anxiety, bipolar symptoms, oppositional-defiant symptoms, stereotypy, and hyperactivity negatively predicted outcome. Risperidone moderated the effect of change in 5'-nucleotidase, a marker of zinc status, for which decrease was associated with improvement only with risperidone, not with placebo. In summary, the benefit-risk ratio of risperidone is better with greater symptom severity. Risperidone can be individually titrated to optimal dosage for excellent response in the majority of children. Weight gain is not necessary for risperidone benefit and may even detract from it. Socioeconomic advantage, low prolactin, and absence of co-morbid problems nonspecifically predict better outcome. Mineral interactions with risperidone deserve further study.

    RECRUITING FOR RESEARCH STUDIES (STANFORD/LPCH)

    Below we have highlighted just a few of our studies that we are recruiting for. For a complete list of all currently recruiting research studies please visit our new website at autismdd.stanford.edu


    Oxytocin treatment trial for social deficits in children with autism

    Stanford University researchers are currently recruiting children with autism to participate in a research study which tests the effects of intranasal oxytocin on social functioning.
    In order to participate in this research study your child must:
    • Be diagnosed with autistic disorder.
      or
    • Be between the ages of 6 and 12 years.
    • Be willing to take an oxytocin nasal spray for at least 4 weeks and provide blood samples.
    • Be willing to participate in behavioral and cognitive testing.
    • Have no serious medical problems.

    You will also receive generalized results regarding your child's cognitive and behavioral assessments. Please contact us at (650) 736-1235 if you are interested.


    New Clinical Trial for Adults with Autism

    This study explores the safety and effectiveness of Pregnenolone, a neuroactive steroid medication to improve behavioral deficits in adults with Autism.

    To be eligible for this study you must:
    • Be between the ages of 18 and 45.
    • Have been diagnosed with an autism spectrum disorder.
    • Be willing to provide blood and urine samples.

    Children and Adolescents are Needed to Participate in Research Studies

    We are actively recruiting children who are typically developing or who have one of several neuropsychiatric diagnoses for many of our studies. We are looking for individuals who are or who have one of the following:

    • Typically Developing
    • Autism Spectrum Disorder diagnosis

    Subjects must be a same-sex twin pair:
    • Where one or both have been diagnosed with an Autism Spectrum Disorder (ASD).
      or
    • Where both are typically developing and in good medical health.
    • Between ages 3-14 years old.

    We are interested in the relationship between hormones and sex steroids in children with autism. We are looking for children (typically developing or with ASD diagnosis):

    • Between the ages of 3-12 years old.
    • Born preterm or full term.
    • Willing to provide a blood sample and complete IQ testing.

    Participants receive up to $50 for completing the study. Please contact us at (650) 736-1235 if you are interested.


    Autism and ADHD Study

    Researchers at Stanford University are recruiting individuals with ASD, ADHD, and typically developing children.

    We are looking for children who:

    • Are between ages of 2-18 years old
    • Are in good medical health
    • Are willing to provide blood, saliva and urine samples

    Each participant will receive $50 upon completion of the study. Please contact us at (650) 736-1235 if you are interested.



    Emotional Reactivity and Regulation in Individuals with Autism Spectrum Disorders

    This study looks at how youth with autism experience their emotions, and to what extent they use emotion regulation strategies to change specific emotions and thus alter the way they feel about a given situation. We hope that our research will lead to changes in increasing the effectiveness of current autism therapies.

    In order to participate in this research study your child must:

    • Between the ages of 8-21 years old in good medical health with or without an ASD diagnosis
    • Be willing to participate in psycholophysiological and neuroimaging experiments
    • Be willing to come to Stanford Hospital and Psychophysiology Lab up to four times

    Each participant will be paid $30 for each completed session. For more information please call (650) 353-5777
