Wanted: ADHD Research on Women & Girls

It is indefensible how little is known about ADHD in women today. Research is nearly non-existent in the way ADHD symptoms change with the hormonal fluctuations of puberty, pregnancy, menopause, and beyond. And experts who study ADHD are deeply concerned — outraged even — about the persistent lack of research on a population that is chronically underdiagnosed and misdiagnosed.

“For decades, girls and women with ADHD have missed out on critical interventions to help manage their ADHD symptoms, primarily because they have largely been left out of ADHD research studies,” says Julia Schechter, Ph.D., co-director of the Duke Center for Girls and Women with ADHD. “Females with untreated ADHD have been put at higher risk for depression and anxiety, intimate partner victimization, and risky sexual behaviors resulting in teen and unplanned pregnancies. Research devoted to girls and women with ADHD is not only an issue of equity but of life or death for some.”

Here, leading experts weigh in on where research is critically needed to guide accurate diagnosis and effective treatment of ADHD in females.

ADHD Research Priority: Defining Sensitive and Precise Screening Tools

Julia Schechter, Ph.D., co-director of the Duke Center for Girls and Women with ADHD

There are numerous research topics related to girls and women with ADHD that deserve thorough investigation. Three specific areas of research that span the life course include:

1. Developing more sensitive and precise screening tools that can better identify girls and women who may have ADHD and require comprehensive evaluation. Many screening tools — particularly those that are freely available — ask raters to report on overt behaviors that align with DSM-5 criteria. Yet, this approach may not be as effective for girls and women. Females with ADHD often compensate for and “mask” their symptoms, making it difficult for observers to rate how frequently a symptom is occurring or whether it is present at all. Research can also focus on developing additional prompts that could be incorporated into existing tools to help raters consider how symptoms may present differently in girls and women (e.g., more likely to be hyperverbal rather than hyperactive). Once developed, these gender-sensitive tools need to be free to use, easy to implement, provide gender or sex-based norms, and be interpretable by those without specialty mental health backgrounds (e.g., teachers, pediatricians).

2. Investigating the role of hormones in ADHD symptom expression in girls and women. This research should examine hormonal levels across the reproductive lifespan including puberty onset, menstrual cycle, pregnancy, postpartum period, and menopause, and post-menopause.

3. Assessing the degree to which girls and women with ADHD require additional or unique treatment approaches. For example, studies can investigate the efficacy of ADHD medication type and dose for girls and women and whether medication effectiveness might interact with hormone levels. With regard to behavioral treatments, research questions might include whether additional modules of CBT for ADHD or behavioral parent training potentially targeting emotion dysregulation could enhance the effectiveness of these psychosocial interventions. In addition, research can explore whether there are certain treatment delivery formats, such as group therapy (vs. individual therapy), that might be more effective for girls and women with ADHD.

ADHD Research Priority: Why ADHD Exacts a Greater Toll on Women

Ellen Littman, Ph.D., clinical psychologist and co-author of Understanding Girls with ADHD

The overarching research question is: Why does ADHD exact a far greater toll on women? Why have researchers refused to explore the dramatic sex/gender differences in outcomes — and how can we compel researchers to care?

Here is the most urgent research needed to improve care for females:

• Studies that will increase recognition and understanding of the widest continuum of presentations, complex trajectories, hormonal mediation, cumulative mood-based impairments, and severity of outcomes.
• How do cycling hormones impact all aspects of female behavior and impairment —including PMS and PMDD (premenstrual dysphoric disorder), and the postpartum, perinatal, and menopause stages?
• To what degree do isolation, shame, and despair lead to self-harm and earlier mortality in females?
• How can we identify symptoms earlier in girls?

These findings will provide a basis for revised, inclusive diagnostic criteria and rating scales to assess internalizing symptoms, functional impairments, masking, and symptom proliferation after puberty.

ADHD Research Priority: The Impact of Perimenopause and Menopause on ADHD Symptoms

Jeanette Wasserstein, Ph.D., clinical assistant professor of psychiatry, at the Icahn School of Medicine at Mount Sinai

An ADDitude survey found that an enormous number of women are diagnosed with ADHD during the perimenopausal and menopausal years and that those who were previously diagnosed experienced a worsening of symptoms. These observations correlate with a period of significant underlying hormonal changes. Since ADHD is a neurodevelopmental disorder thought to be typically present during the childhood or teen years, this apparently ‘new onset’ or worsening of ADHD implies an important role for sex hormones in the expression of some ADHD symptoms.

Such observations also imply that there may even be two types of women who are diagnosed with ADHD during this period: Those who were borderline ADHD their whole lives but did not meet criteria until their symptoms worsened and those who are entirely ‘new onset.’ Unfortunately, almost no research exists regarding the role of hormones on ADHD during the climacteric. Since women represent 50% of the world’s population and all will experience menopause if they live into their 60’s the impact of perimenopause and menopause on ADHD symptoms is an enormously unrecognized and important topic in global female health.
