In fragile X syndrome, hyperactivity and inattention are frequently observed behavioral manifestations. This condition is associated with a range of cognitive and developmental challenges, leading to difficulties in attention regulation and increased activity levels. Individuals with fragile X often exhibit symptoms similar to those seen in Attention-Deficit/Hyperactivity Disorder (ADHD), which includes impulsivity, hyperactivity, and challenges with maintaining focus on tasks. These behavioral characteristics are tied to the underlying genetic and neurobiological factors associated with fragile X syndrome, resulting in observable patterns in children and adolescents.

While there may be other behavioral issues present, such as obsessive behaviors, severe withdrawal, and a higher likelihood of comorbidity with autism spectrum disorders, the hallmark symptoms related to hyperactivity and inattention are more commonly referenced in the context of fragile X syndrome. The prevalence of these symptoms significantly impacts the daily functioning and educational experiences of affected individuals.
