A developmental disorder marked by persistent difficulty sustaining attention,…

Concept

Neurodevelopmental disorders begin during development and affect cognitive, behavioural, or learning-related functioning.

ADHD is characterized by a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development.

Application

The stem combines sustained-attention difficulty, reduced impulse control, and hyperactivity. These are the core symptom domains used to describe ADHD.

Contrast

• Visual-perceptual processing difficulty concerns interpreting visual information, such as spatial relationships or visual discrimination.

• Language processing disorder concerns understanding, organizing, or expressing spoken or written language.

• Executive functioning difficulty concerns planning, working memory, inhibition, and task management; it names a set of cognitive-control difficulties rather than this full symptom cluster.

• ADHD names the neurodevelopmental condition defined by the combined symptom pattern in the stem.

Cross-check

The attention, impulse-control, and activity-level clues span multiple domains, so a single visual, language, or executive-process difficulty does not account for the entire pattern.

Result

Therefore, the disorder is Attention-Deficit/Hyperactivity Disorder (ADHD).
