This excerpt from "You Said, I Heard: ADHD in Relationships" discusses the challenges couples face when one or both partners have ADHD. It highlights how differences in thinking and processing information can lead to misunderstandings, emphasizing the importance of empathy and a shared approach to learning about ADHD. The text introduces the Executive Functions framework as a way to understand the underlying mechanisms of ADHD symptoms like inattention, impulsivity, and organization difficulties, and also presents the EcoSystem model (neurochemistry, metacognitive systems, and environment) to explain the various influences on executive function. The book suggests practical steps for couples to collaboratively understand and address these challenges, using real-life examples to illustrate the concepts.
