Emotion regulation in adults with Klinefelter syndrome (47,XXY): Neurocognitive underpinnings and associations with mental health problems

This paper is from ACRC member and AXYS Family Conference presenter Dr. Sophie van Rijn. While only 26 men participated in this study and the results are from a self-reported questionnaire, this paper shines a light on issues commonly faced by adults with 47,XXY.

The aim of this study was to evaluate if language and executive functioning deficits in individuals with 47,XXY contribute to emotion regulation problems.

Results: Atypical emotion regulation strategies were found in the XXY group, with increased expression of emotions (69%), avoiding (65%), distraction seeking (54%), and passive coping (54%). More difficulties in mental flexibility and attention regulation, and speeded responding were associated with more pronounced emotion expression (emotional outbursts). Emotion regulation problems were associated with symptoms of anxiety, depression, thought problems, and hostility.

Conclusion: This study has identified emotion regulation as a potential target for treatment and intervention, with a specific focus on executive functions in the management of emotions in individuals with 47,XXY.

A review of neurocognitive functioning and risk for psychopathology in sex chromosome trisomy (47,XXY, 47,XXX, 47,XYY)

Dr Sophie van Rijn, one of our 2019 Family Conference speakers, wrote this excellent opinion paper “A review of neurocognitive functioning and risk for psychopathology in sex chromosome trisomy (47,XXY, 47,XXX, 47,XYY).”

This paper reviews studies that illustrate an increased risk for social, emotional and behavioral problems in individuals with 47,XXY, 47,XXX, or 47,XYY. The primary focus of research in this area has been on language and learning problems; more recent research suggests that impairments in executive functioning, social cognition and emotion regulation may also be key factors underlying the risk for behavioral problems and mental disorders. Directions for future research are provided.

Social cognition and underlying cognitive mechanisms in children with an extra X chromosome: a comparison with autism spectrum disorder

This 2014 paper by Dr. Sophie van Rijn is an excellent study on the Theory of Mind and “the reported social behavioral difficulties in individuals with an extra X chromosome” that “include shyness, social withdrawal, social anxiety, social immaturity, difficulties in peer relationships, social impulsivity, communication difficulties, reduced social assertiveness and difficulties with ‘being sensitive and responsive to the feelings and rights of others.”

“Individuals with an extra X chromosome are at increased risk for autism symptoms. This study is the first to assess theory of mind and facial affect labeling in children with an extra X chromosome.”

Recent advances in managing and understanding Klinefelter syndrome

Klinefelter syndrome can present as a wide spectrum of clinical manifestations at various stages in life, making it a chromosomal disorder with no standardized set of guidelines for appropriate management. Understanding the genetic and hormonal causes of this syndrome can allow physicians to treat each patient on a more individualized basis. The timing of diagnosis and degree of symptoms can guide management. This report will provide an updated review of the clinical presentation at various stages in life and the implications for management.

When It’s Not Just ADHD: Uncovering Comorbid Conditions

Research has shown that a high percentage of individuals with x and y chromosome variations often have one or more characteristics associated with ADHD. Other research has shown that a high percentage of ADHD individuals may also have secondary conditions that can benefit from treatment. These conditions would include depression, anxiety, learning disabilities, language disabilities, executive function difficulties and others. This month’s featured research article provides more information about these relationships and secondary conditions.

Anxiety and depression in Klinefelter syndrome: The impact of personality and social engagement

Neuroses and neuroticism: What’s the difference?

Research Suggests a Cure for Neuroticism

The December Featured Research article is a very recent paper from the Klinefelter adult specialty clinic in Denmark. Dr. Gravholt and his team examined the relationships between personality traits, social engagement, and anxiety & depression symptoms among KS patients. Their research suggests that neuroticism may play a central role in attention switching, anxiety and depression among patients with Klinefelter syndrome. The central role of neuroticism suggests that it may be used to help identify and treat KS patients at particularly high-risk for attention switching deficits, anxiety and depression and could be very helpful in designing interventions and programs to significantly help these individuals.

We are also including several papers that may help explain more about neuroses, neuroticism and treatment suggestions.

Transitioning to Adulthood

The suggested Featured Research paper this month is actually a link to the 10-part series of booklets on the AXYS website titled Transitioning to Adulthood (located under the Resources tab). This series provides excellent information for all parents/individuals trying to understand or respond to the challenges that can be associated with this transition. It was originally written for the 48,XXYY population but it has broad applicability to any person or family that may be struggling with various issues associated with any SCA condition. We highly recommend reviewing this information for everyone with teenagers that may have an X or Y chromosome variation.

Executive Function 101

This month’s research paper is actually an e-book published by The National Center for Learning Disabilities titled Executive Function 101.  This is such a critical area for both children and adults and we believe it is frequently under-diagnosed and under-recognized by many health and education professionals that are working with SCA individuals. It is important that parents and SCA individuals learn more about the underlying brain functions that are associated with executive skills and take steps to improve and develop these skills. They are extremely important for general social functioning, learning, working and relationships and it will be very helpful to read and consider some of the suggestions that are presented in this book. There are also many papers and other books on Executive Function that you can find in the AXYS library as well. The more you know, the better you will be able to assist your child or get others to understand how to help.

Living with Klinefelter Syndrome (47,XXY) Trisomy X (47, XXX) and 47, XYY: A Guide for Families and Individuals Affected by Extra X and Y Chromosome Variations

This month’s featured research paper is actually Virginia Cover’s excellent resource book that has been in the AXYS library for a number of years but we felt it was important to put it in the spotlight again for parents and individuals dealing with x and y chromosome variations. It provides invaluable information that will help you better understand these conditions and should be used to learn more about ways to support growth and development as well as teaching others (doctors, schools, family and friends) about the challenges that may be involved. We highly recommend reading this book and making sure others are aware of the information it contains.

Cognitive and Neurological Aspects of Sex Chromosome Aneuploidies (from thelancet.com/neurology)

This month’s paper, by Drs. Reiss and Hong at Stanford University and first published in 2014, is a strong science-based discussion on the impact of XXY and XYY on cognitive and neurological functions. It can be difficult to interpret all the information provided, but it is an excellent research article for other health and education professionals to help them understand the neurophysiology involved and why individuals with challenges may require special diagnoses and treatment. We often hear reports from families and individuals that health professionals do not seem to be aware of current research involving non-medical aspects of SCA conditions so this definitely should be shared with physicians, teachers and others involved in any treatment or support programs. It also reinforces why it can be so important to have evaluations completed at specialty clinics by experienced clinicians.
