Earlier this week, JAMA Pediatrics released the findings of a study which suggested that prenatal exposure to antidepressants may increase the risk of autism spectrum disorders (ASDs). Not surprisingly, this has created a considerable amount [...]
Last week was National Folic Acid Awareness Week at the Centers for Disease Control (CDC), so this seems like a great time to remind women (and their caregivers) of the importance of folic acid in the prevention of birth defects. By taking the recommended dosage of folic acid daily, women will reduce the risk of neural tube defects by 50% - 70%. In addition, women who take folic acid supplements are less likely to give birth to a child with an autism spectrum disorder.
The European Medicine Agency (EMA)'s Pharmacovigilance and Risk Assessment Committee recently recommended strengthening the restrictions on the use of valproic acid in women of reproductive age. Over the last few years, we have seen a host of articles documenting the deleterious effects of valproic acid on the developing fetus:
Autism spectrum disorders (ASDs), which include childhood autism, autistic disorder, Asperger syndrome, atypical autism, and other pervasive developmental disorders, are characterized by social and communication difficulties and by stereotyped or repetitive behaviors and interests. It [...]
We have received many emails and calls from colleagues and patients regarding the recent article on the safety of SSRI use during pregnancy published in the New York Times. In this article, health writer Roni Caryn Rabin, detailed the risks associated with the use of antidepressants during pregnancy.
Two recent epidemiologic studies have demonstrated an association between prenatal exposure to selective serotonin reuptake inhibitor antidepressants (SSRIs) with autism spectrum disorders (ASD; Croen et al 2011, Rai et al, 2013). One important imitation of these two studies is that parental psychiatric disorder in itself is associated with an increased risk of ASD in the offspring, and these studies could not distinguish between the effects of drug exposure and the consequences of the underlying maternal psychiatric illness. Two new studies shed light on the association between prenatal antidepressant exposure and risk of autism spectrum disorder in the offspring.
In a recent editorial in The Annals of Internal Medicine entitled “Enough Is Enough: Stop Wasting Money on Vitamin and Mineral Supplements,” authors make a case that multivitamins are not a good value (Dec 17, 2013 issue). This editorial was based on new research that demonstrated that there was no association between multivitamin use and rates of mortality, cognitive decline and recurrent cardiovascular events in three different studies. The assertion that multivitamins are not worth the money was widely reported in the media.
It is estimated that autism spectrum disorders (ASD) affect about 1% to 2% of children. Research carried out in twins and families indicate that ASD is highly heritable; however, it is generally believed that while genetic factors play an important role, there is an interplay between genetic and environmental factors in the etiology of this disorder. Various environmental exposures have been implicated, including vaccinations, mercury, air pollution, insecticides, and infection.
There have long been concerns regarding the use of the anticonvulsant valproate (Depakote, VPA) during pregnancy. First trimester use of valproate has been associated with a 3-5% risk of neural tube defects, as well as an increased risk of other malformations affecting the heart and other organ systems. Multiple reports have also indicated that in utero exposure to valproate may also negatively affect cognitive development.
It is now estimated that autism spectrum disorders (ASD) affect about 1% to 2% of the population. Data derived from twin and sibling studies indicate that ASD is highly heritable. While genetic factors clearly play an important role, other studies point to an interplay between environmental and genetic factors in the etiology of this disorder. Over the years, various environmental exposures have been implicated, including vaccinations, mercury, and insecticides; however, it has been difficult to generate solid evidence linking specific environmental factors with increased risk for autism.
