Welcome, everybody. My name is Eric Welin, and I am a team member here at FRAXA Research Foundation. I am also a parent of two wonderful boys with fragile X syndrome, which makes World Fragile X Day particularly special to me. Today, we have Dr. Carrie Banan joining us. She will be discussing anxiety, and I will turn it over to her now.
Wonderful! Thank you so much, Eric, for the introduction. I am really excited to be here, especially on World Fragile X Day. As Eric mentioned, I am a physician and a developmental-behavioral pediatrician at the Greenwood Genetic Center in Greenville, South Carolina. I have been involved in the fragile X space for close to ten years. I currently direct the fragile X Clinic at the Greenwood Genetic Center and serve as the principal investigator on several clinical trials involving fragile X syndrome. Our Center is also a participating site in the FORWARD study, the fragile X natural history study.
I wanted to mention my background to highlight my personal connection to fragile X syndrome. There are many families and individuals affected by fragile X syndrome who are very dear to me. Today, I stand with these families and all of you to celebrate those who shine in the face of fragile X syndrome, as the FRAXA website says. I am here celebrating my families, my patients, and all of you as well. Thank you for having me here today.
As I mentioned, I will be discussing anxiety in fragile X syndrome and its many manifestations. Anxiety is a vital topic regarding fragile X because most, if not all, individuals with fragile X syndrome experience anxiety, with many facing high levels of it. It is especially important to recognize the various ways anxiety can manifest in this population. In both children and adults with fragile X, we see behaviors such as irritability, aggression, perseverative behavior, reassurance-seeking, pacing, and many other maladaptive behaviors. Today, I will explain how anxiety often underlies these behaviors.
Anxiety is frequently cited as one of the most problematic symptoms of fragile X syndrome. A notable study published in 2019 by Jane Dixon Weber and others examined treatment priorities among 467 participants, which included family members, caregivers, professionals, and individuals with fragile X. The study found that anxiety was the most problematic symptom of fragile X syndrome, followed by behavior problems, which many acknowledged are often a result of anxiety. The third area of concern reported was learning and cognitive challenges.
Understanding why anxiety is so prevalent in fragile X syndrome is key. Individuals with fragile X syndrome are neurobiologically predisposed to significant anxiety, meaning their nervous systems and brains are structured in a way that makes them more susceptible to experiencing high levels of fear and anxiety compared to the neurotypical population.
To explain this further, the amygdala, a small almond-shaped structure in the brain, is responsible for emotional processing, particularly fear and anxiety. When our environments prompt fear, the amygdala sends a distress signal to the hypothalamus, activating the sympathetic nervous system and triggering the fight-or-flight response. This process generates behavioral outputs related to fear and anxiety, which we have all experienced under threat.
In those with fragile X syndrome, studies have shown that there are denser neural connections within the amygdala, leading to chronic overstimulation, which gives them an anxious brain. This means that even minor environmental changes can provoke a dramatic fight-or-flight response that is disproportionate to the actual threat. For example, unexpected changes—such as taking a different route to school—could trigger a response in a child with fragile X similar to what they would experience if faced with a bear.
Chronic overstimulation of the amygdala means that individuals with fragile X are hyperaroused and in a constant state of vigilance. Situations that seem minor to us can trigger severe anxiety responses, leading to behaviors such as aggression, avoidance, or complete shutdown. This can be incredibly impairing both for the individual and their families, affecting their overall quality of life.
As we celebrate World Fragile X Day, it’s essential to acknowledge the accomplishments of individuals despite these challenges. Many experience significant anxiety daily, often resulting in behaviors that may appear as aggression or avoidance, which are actually responses to overwhelming fear. Thus, understanding these connections helps us frame interventions.
Some maladaptive behaviors linked to anxiety include irritability and aggression, often leading to fight responses like meltdowns. In contrast, some may exhibit flight responses such as shutting down or avoidance. In these circumstances, the underlying anxiety is not merely an emotional issue but a physiological one that drives behavior, illustrating the need for appropriate interventions and understanding.
Next, I would like to discuss non-pharmacological interventions aimed at managing anxiety. Occupational and speech therapies can significantly reduce anxiety and improve overall functioning by addressing communication skills and helping individuals learn calming techniques. Avoiding environmental triggers is also crucial. Maintaining predictable environments, using clear language, and implementing consistency can help create a calming atmosphere. Each person is unique, and strategies should be tailored to their specific needs.
While non-pharmacological options can be effective, some individuals may also benefit from medication to manage anxiety. It’s important to work with qualified healthcare providers who understand fragile X syndrome and can tailor treatment plans accordingly.
I want to emphasize that resources are available for individuals and families affected by fragile X syndrome. There are guides and webinars offered by organizations such as the FRAXA Research Foundation, providing valuable insights into managing daily challenges and improving quality of life.
Before concluding, I’d like to address some specific questions that have been submitted regarding anxiety, treatment options, and clinical trials associated with fragile X syndrome.

In summary, understanding anxiety in fragile X syndrome requires recognizing its physiological roots and varied manifestations. We must address the needs of individuals with fragile X syndrome holistically—both through therapeutic interventions and medications when necessary—to enhance their quality of life and support their families. Thank you all for your participation today, and I hope this discussion has been informative and beneficial to you. Thank you, everyone!
