Mild to Moderate Iodine Deficiency in Pregnancy Associated with Lower Cognitive Functioning
Iodine is essential for thyroid hormone synthesis. We have known for a long time that severe iodine deficiency during pregnancy may affect the cognitive development of the unborn child. According to a recent Lancet study, even children born to women with mild-to-moderate iodine deficiency during pregnancy are at increased risk for lower IQ and reading ability (assessed at age 9). The most severe effects were observed among children born to women with severe deficiency (<50 mcg/g iodine:creatinine ratio).Â
Prenatal Exposure to Antidepressants and Risk of Autism
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.
Valproic Acid and Pregnancy: FDA Issues Warning
There have been multiple recent reports indicating that the use of valproate during pregnancy may be associated with lower IQ, cognitive problems, and developmental delays in exposed children. This has prompted the FDA to issue a warning regarding the use of valproate-containing drugs, including Depakote and Depakene, during pregnancy:
Soy Supplements for Menopausal Symptoms: Higher Doses and More Frequent Dosing May Help
Studies assessing the effectiveness of complementary and alternative medicines (CAM) for the treatment of menopause-related hot flashes have yielded conflicting results. Most studies have demonstrated that treatments such as soy and black cohosh are not likely to be effective in most women; however, a new study suggests that women who take higher doses (100 to 200 mg)of isoflavones and more frequent dosing (2-3 times per day) may experience a greater reduction in the frequency of hot flashes.
Atypical Antipsychotic Medications: What Do We Know About Their Reproductive Safety?
Atypical antipsychotic medications are commonly used for the treatment of schizophrenia and bipolar disorder. Despite the increasing use of these medications in women of child-bearing age, there is still relatively little data regarding the reproductive safety and long-term neurodevelopmental effects of these medications. A recent study assessed the development of 76 infants with fetal exposure to atypical antipsychotics.
New Research from the CWMH: Vasomotor Symptoms Frequently Recur After Discontinuation of SSRI
For the treatment of menopausal vasomotor symptoms (VMS), such as hot flashes and night sweats, selective serotonin reuptake inhibitors (SSRIs) are effective and well-tolerated. Positive effects are observed within 4 weeks of the initiation of treatment. However, we do not know how long treatment with an SSRI must be continued in order to maintain control of VMS. Nor do we know if VMS will recur after discontinuation of SSRI or if recurrent VMS may be less frequent or less bothersome after receiving SSRI treatment. A recent report from Dr. Hadine Joffe and colleagues at the Center for Women’s Mental Health assessed the recurrence of vasomotor symptoms in women treated with SSRIs.
