Attention-Deficit Hyperactivity Disorder: Clinical Considerations for Women

Quantification of ADHD medication in biological fluids of pregnant and breastfeeding women with liquid chromatography: a comprehensive review

Attention Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that has long been considered a concern only in the pediatric population. However, symptoms often sustain into adulthood and may require medication. For women with ADHD, this also means dealing with the disorder during the reproductive period. Medication safety during pregnancy and breastfeeding is a critical concern, and the potential transfer of ADHD medication to infants remains a topic of scientific interest. The quantification of ADHD medications in both maternal blood and breast milk are vital for understanding their pharmacokinetics and potential exposure risks for (nursing) infants. This review aims (1) to compile and critically assess existing research on the transfer of ADHD medications into breast milk and the potential implications for nursing infants and (2) to provide a comprehensive overview and discussion of the literature regarding the quantification of methylphenidate, amphetamine, atomoxetine, viloxazine, guanfacine, clonidine and bupropion in the blood, urine, oral fluid, and breast milk with liquid chromatography. A literature search was conducted using PubMed, Scopus, and Web of Science, to identify relevant articles published from January 2014 up to December 2023. We illustrate the lack of methods to simultaneously monitor multiple ADHD medications as well as the lack of developed methods for breast milk. Finally, we highlight the need for continued research to refine our understanding of medication transfer into breast milk and potential risks, and to develop clinical guidelines to support mothers with ADHD in making informed choices regarding medication use during pregnancy and lactation.

Modelling ADHD-Like Phenotypes in Zebrafish

The use of multiple species to model complex human psychiatric disorders, such as ADHD, can give important insights into conserved evolutionary patterns underlying multidomain behaviors (e.g., locomotion, attention, and impulsivity). Here we discuss the advantages and challenges in modelling ADHD-like phenotypes in zebrafish (Danio rerio), a vertebrate species that has been widely used in neuroscience and behavior research. Moreover, multiple behavioral tasks can be used to model the core symptoms of ADHD and its comorbidities. We present a critical review of current ADHD studies in zebrafish, and how this species might be used to accelerate the discovery of new drug treatments for this disorder.

Pregnancy and Parenthood Among Autistic Adults: Implications for Advancing Maternal Health and Parental Well-Being

Background

Strikingly little research has considered how autistic adults experience pregnancy and parenthood, two key transition periods in adult development with potentially far-reaching implications for physical and psychosocial health outcomes across the lifespan. This article reviews the research on pregnancy and parenthood among autistic adults, to summarize existing research and identify future directions to advance this critical area of study.

Methods

We conducted a systematic review of the literature on pregnancy and parenthood among autistic adults. Researchers extracted selected articles for key information, including methodology and sample size, study location, demographic characteristics of participants, measurement approaches, and key study findings.

Results

Overall, we identified 13 studies that used a range of quantitative and qualitative approaches to study pregnancy experiences and outcomes and parenthood among autistic adults. The findings show that autistic adults (1) experience difficulties and dissatisfaction communicating with health care providers throughout pregnancy and birth, (2) are more likely to experience depression during and after pregnancy, and (3) experience higher rates of pregnancy complications, including preterm birth, cesarean delivery, and pre-eclampsia. During parenthood, autistic adults report lower parenting competence, experience parenthood as isolating, have difficulty communicating with professionals about their child and are questioned by providers about their ability to parent, experience high rates of involvement with child protective services, and express a desire for increased parenting support. Autistic adults also reported parenting strengths, including high levels of finding parenthood rewarding and putting their children's needs ahead of their own.

Conclusions

A key limitation of the literature is the significant lack of sociodemographic diversity among participants, the small number of existing studies, and reliance on cross-sectional mono-method designs. Future research should be conducted in partnership with autistic adults to develop assessment and intervention approaches for supporting pregnancy health and parental well-being among diverse and underserved communities.

Lay summary

Why is this topic important?: Very little is known about how autistic adults experience pregnancy and parenthood. Better understanding these experiences is important, because pregnancy and parenthood are key transition periods in adult development that are associated with a range of health outcomes later in life.What is the purpose of this article?: This article reviews the existing research on pregnancy and parenthood among autistic adults. We wanted to summarize what is already known, evaluate how that knowledge was created, and consider who has and who has not been included in this research to inform future research. We summarized 13 studies that considered pregnancy or parenthood among autistic adults.What did the authors find about pregnancy among autistic adults?: One study used data from hospital and birth records in Sweden, and showed that autistic women experience higher rates of pregnancy complications, such as preterm birth (early delivery before 37 weeks), cesarean delivery, and pre-eclampsia (a condition defined by high blood pressure during pregnancy). Two studies had autistic and nonautistic adults fill out online surveys about their experiences, and found that autistic adults are more likely to have depression during and after pregnancy, have more difficulty interacting with health care professionals at pregnancy appointments and during the birth process, and feel that information and support services for pregnancy do not always meet their needs. Autistic women also reported that sensory differences can make health care visits during pregnancy especially difficult, and described that they may experience anxiety and confusion when interacting with health care staff.What did the authors find about parenthood among autistic adults?: The research we reviewed showed that autistic adults experience strengths and difficulties in parenting. Many autistic adults found parenthood rewarding, but also felt isolated as parents and had difficulty communicating with health care professionals about their children. Autistic adults also had high rates of interacting with child protective services (CPS). Some research also found that autistic adults had lower self-confidence in parenting, although findings are mixed.What are the recommendations for future research and practice?: We need to develop support strategies to promote pregnancy health and parenting satisfaction in partnership with autistic adults. For example, it may be helpful to develop communication tools that can support autistic adults during pregnancy, labor, and birth. We also recommend that future research develop questionnaires to ask autistic adults about their pregnancy and parenting experiences in sensitive ways, so that in the future providers can regularly ask autistic adults about their support needs. Most importantly, it is critical that future research also include more diverse autistic participants in their research, including racial/ethnic and sexual and gender minorities.How will these findings help autistic adults now or in the future?: We hope that this article will help guide future research that strives to better understand how autistic adults experience pregnancy and parenthood. Ultimately, we believe this research can lead to supports and intervention strategies that can improve pregnancy health and parental well-being for autistic adults.
