A 38-year-old female executive presents for evaluation of concentration difficulties that have worsened since her recent promotion to a senior management role. She describes difficulty prioritizing competing tasks, frequently starting projects but not completing them, chronic lateness despite multiple alarm systems, and an inability to maintain organizational systems at work. Her childhood school records describe her as 'bright but daydreamy' with inconsistent academic performance. She has no history of substance use, mood disorders, or anxiety, and her PHQ-9 score is 3. Neuropsychological testing reveals average IQ but significant deficits on the Wisconsin Card Sorting Test and Trail Making Test Part B. Which assessment interpretation best accounts for this clinical presentation?
