Maternal blood folate status during early pregnancy and occurrence of autism spectrum disorder in offspring: a study of 62 serum biomarkers

ConclusionsOur findings suggest that high maternal serum folate status during early pregnancy may be associated with the occurrence of ASD in offspring. No inference about physiological mechanisms behind this observation can be made at the present time because blood folate levels may have complex relations with nutritional intake, the cellular folate status and status of other B-vitamins. Therefore, further investigations, which may clarify the potential role and mechanisms of maternal blood folate status in ASD risk and the interplay with other potential risk factors, in larger materials are warranted.

This study investigated whether antenatal exposure to antidepressants (ADs) increases the risks of autism spectrum disorders (ASD), attention deficit/hyperactivity disorders (ADHD), schizophrenia and other mental illnesses, and cognitive and developmental deficits in infants or preschool children. PubMed, EMBASE, BIREME/BVS databases were searched to identify studies examining associations of ADs in pregnancy with neurodevelopmental and psychiatric disorders. Twenty studies addressed ASD and/or ADHD risks while 30 focused on developmental and cognitive deficits in infants or preschool children. Most studies detected no ass...

Autism spectrum disorder is a neurodevelopmental disorder characterized by reduced social interactions, impaired communications, and stereotypic and repetitive behavior with different degrees of severity. The etiology of autism spectrum disorder is unknown, although the interaction of genetic and environmental factors is believed to play a fundamental role in the process. The main aim of this narrative review is to discuss the current knowledge about the interrelationships between vitamin D deficiency during pregnancy and autism spectrum disorder development. Literature analysis showed that vitamin D supplementation during...

Existing evidences indicate that GLA has reproductive toxicity, while data concerning the effects of prenatal GLA exposure on neurodevelopment is rather limited. Here we employed a mouse model exposed to GLA prenatally. Reduced locomotor activity, impaired memory...

AbstractObjectiveTo evaluate the long-term pediatric neuropsychiatric morbidity of children born to obese patients.Study designA population-based cohort analysis was performed comparing all deliveries of obese (maternal pre-pregnancy body mass index of 30  kg/m2 or more) and non-obese patients between 1991 and 2014 at a single tertiary medical center. Hospitalizations of the offspring up to the age of 18  years involving neuropsychiatric morbidities were evaluated according to a pre-defined set of ICD-9 codes, including autistic, eating, sleeping and movement disorders, cerebral palsy, developmental disorders, an...

(University of Cambridge) Autistic mothers are more likely to report post-natal depression compared to non-autistic mothers, according to a new study of mothers of autistic children carried out by researchers at the University of Cambridge. A better understanding of the experiences of autistic mothers during pregnancy and the post-natal period is critical to improving wellbeing.

This study proposed a comprehensively integrated theoretical framework for examining the intention to undergo PGT to detect ASD susceptibility genes and subsequent abortion decision-making among Taiwanese mothers of children affected by ASD. Survey data from 333 mothers of children with ASD in 236 elementary schools with special education services in Taiwan were collected and analyzed using structural equation modeling. Approximately two-thirds of the participants (66.6%) would undergo PGT to detect ASD susceptibility genes; more than half (53.1%) would terminate the hypothetically ASD-affected pregnancy. Abortion intentio...
