Question 12

Attention-deficit/hyperactivity disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent patterns of inattention and impulsivity. These symptoms can significantly impact daily functioning and development in various settings, such as at school and home.

A) Autism spectrum disorder

Autism spectrum disorder (ASD) is primarily characterized by challenges in social communication and the presence of restricted or repetitive behaviors. While individuals with ASD may exhibit attention issues, it is not defined primarily by inattention and impulsivity, making it an incorrect choice for this question.

B) Tourette syndrome

Tourette syndrome is a neurological disorder characterized by repetitive, involuntary movements and vocalizations known as tics. It does not inherently involve symptoms of inattention or impulsivity, thus it is not applicable to the question regarding a disorder defined by these traits.

C) Fragile X syndrome

Fragile X syndrome is a genetic condition that causes intellectual disability and developmental delays, which can include attention deficits. However, it does not specifically classify as a disorder of inattention and impulsivity, making it an unsuitable choice for this question.

D) Attention-deficit/hyperactivity disorder

Attention-deficit/hyperactivity disorder is indeed the neurodevelopmental disorder that is explicitly defined by symptoms of inattention and impulsivity. This disorder is recognized for its impact on an individual’s ability to focus and control impulses, aligning perfectly with the question's criteria.

Conclusion

Attention-deficit/hyperactivity disorder is the only option that accurately describes a neurodevelopmental disorder characterized by inattention and impulsivity. The other options, while related to developmental and neurological conditions, do not fulfill the specific criteria outlined in the question. Thus, ADHD is definitively the correct answer.
