Antidepressants do not cause autism

PlayPlay

In all the recent hype on the “overprescribing” of psychiatric medications, there is a circulating rumor antidepressant use in the mother during pregnancy has could be linked to an autism diagnosis in the child. Thankfully, there is research on this topic, and the results are clear: antidepressant exposure during pregnancy does not cause autism in children. Where would this idea come from? Early studies did show a weak link, but the association arises because there is a genetic link between having a psychiatric disorder like anxiety and stress and autism. Don’t stop taking your meds unless you discuss it with your doctor. References below:

What is the real prevalence of ASD?

Unfortunately this podcast does not really provide an answer, but does highlight data published over the holidays which shows in another dataset, that the prevalence of autism seems to be leveling out, rather than continue to increase as it has done for the past several decades.  It isn’t the final word and clearly there may be exceptions, but now two national datasets have shown no further increase in autism prevalence in the last few years of looking.  Is it 1:68 as reported in one study or 1:39 in another?  Is it somewhere in between?  Still to early to say, but white boys seem to be the most likely to get a diagnosis no matter where you look.  Also, folic acid proves to show an effect on the probability of not just an autism diagnosis, but autism symptoms.  This is especially important for women taking anti epileptic medications for seizures and bipolar depression.  Welcome to 2018!
