A Systematic Review of the Relationship Between Neurodiversity and Psychosexual Functioning in Individuals with Autism Spectrum Disorder (ASD) or Attention-Deficit/Hyperactivity Disorder (ADHD)

Special considerations for assessing and caring for autism in girls and women

PURPOSE OF REVIEW

As the specificities of autistic women are increasingly recognized, this review aims to highlight emerging areas of research. These areas primarily focus on measurement bias of diagnostic tools, the physical and mental health of autistic women, and the unique aspects of the lives of autistic women, both personally and professionally across all life stages.

RECENT FINDINGS

Conventional diagnostic tools struggle to capture the specificities of autism in females, but more sensitive instruments like the GQ-ASC (Girls' Questionnaire for Autism Spectrum Conditions), later also referred to as Q-ASC (Questionnaire for Autism Spectrum Conditions) in the scientific literature, show better performances. Autistic women face particular challenges, including an increased risk of physical and mental health problems throughout their lives as women (puberty, motherhood, menopause). Autistic women also encounter specific difficulties in their employment that require greater consideration.

SUMMARY

The findings of this review identify research areas that need to be developed to better understand and support autistic girls and women and to enhance clinical practice for them.

Risk of suicide attempt with gender diversity and neurodiversity

There is growing concern about psychiatric illness co-occurring with gender-diversity and neurodiversity, including risk of suicidal behavior. We carried out systematic reviews of research literature pertaining to suicide attempt rates in association with gender- and neurodiversity, with meta-analysis of findings. Rates of suicidal acts ranked: gender-diverse versus controls (20.1% vs. 1.90%; highly significant) > autism spectrum disorder (4.51% vs. 1.00%; highly significant) > attention deficit-hyperactivity disorder (7.52% vs. 4.09%; not significant). Attempt rates also were greater among controls who included sexual minorities (5.35% vs. 1.41%). The rate among male-to-female transgender subjects (29.1%) was slightly lower than in female-to-male subjects (30.7%), who also were encountered 24.3% more often. In sum, suicidal risk was much greater with gender-diversity than neurodiversity. Suicide attempts rate was somewhat greater among female-to-male transgender subjects. Available information was insufficient to test whether suicidal risk would be even greater among persons with both gender- and neurodiversity.

Improving autism identification and support for individuals assigned female at birth: clinical suggestions and research priorities

Emerging evidence suggests that the higher prevalence of autism in individuals who are assigned male than assigned female at birth results from both biological factors and identification biases. Autistic individuals who are assigned female at birth (AFAB) and those who are gender diverse experience health disparities and clinical inequity, including late or missed diagnosis and inadequate support. In this Viewpoint, an international panel of clinicians, scientists, and community members with lived experiences of autism reviewed the challenges in identifying autism in individuals who are AFAB and proposed clinical and research directions to promote the health, development, and wellbeing of autistic AFAB individuals. The recognition challenges stem from the interplay between cognitive differences and nuanced or different presentations of autism in some AFAB individuals; expectancy, gender-related, and autism-related biases held by clinicians; and social determinants. We recommend that professional development for clinicians be supported by health-care systems, professional societies, and governing bodies to improve equitable access to assessment and earlier identification of autism in AFAB individuals. Autistic AFAB individuals should receive tailored support in education, identity development, health care, and social and professional sense of belonging.
