Which set of behaviors is commonly observed in Fragile X Syndrome?

• A. Hyperactivity, hand flapping and problems with social interactions
• B. Weight gain and fatigue
• C. Excellent language skills
• D. Strong memory and focus

Answer: (A)

Fragile X syndrome is an inherited neurodevelopmental disorder that often presents with behavioral and social-communication challenges. The combination of hyperactivity, repetitive hand movements (like hand-flapping), and difficulties in social interactions is a characteristic pattern seen in many individuals with this condition. These behaviors reflect difficulties with attention, sensory processing, and social reciprocity that are common in Fragile X.

The other descriptions don’t align with the typical Fragile X profile. Weight gain and fatigue aren’t defining features of the syndrome. Language skills are usually affected, with language delays or uneven development rather than excellent language. Memory and focus are not typically described as strong in Fragile X, where attention and executive functioning can be impacted.
