Understanding ADHD

This module establishes a strong foundation by defining ADHD as a neurodevelopmental, evidence-based condition characterised by persistent patterns of inattention and/or hyperactivity-impulsivity. It explores global prevalence, lifespan persistence, and the three DSM-5-TR presentations, helping participants understand that ADHD is not a result of poor parenting or lack of effort.

The module also examines the historical evolution of ADHD, highlighting the shift from stigma to scientific understanding. It emphasises the functional impact of untreated ADHD, including academic difficulties, relationship challenges, mental health risks, and reduced quality of life. Participants gain a clear, stigma-free understanding of ADHD and its real-world significance.

This module provides an in-depth understanding of the neurobiology of ADHD, focusing on the role of dopamine and norepinephrine in regulating attention, behaviour, and executive functioning. It introduces the “Goldilocks principle” of optimal neurotransmitter balance and explains how disruptions affect the prefrontal cortex.

Participants explore brain structure and network differences, including delayed cortical maturation and dysfunction in attention and reward systems. The module also covers genetic influences and environmental risk factors, reinforcing that ADHD is highly heritable and biologically driven. Barkley’s behavioural inhibition model is introduced to explain how executive function difficulties arise from core neurological mechanisms.

This module examines the core symptoms of ADHD—inattention, hyperactivity, and impulsivity—along with their varied presentations across age, gender, and context. It provides practical examples to help participants recognise how these symptoms appear in real-life situations.

A key focus is emotional dysregulation, an often overlooked but highly impactful feature of ADHD, including rejection sensitivity and rapid emotional shifts. The module also highlights under-recognised groups, such as girls and adults, and addresses common misinterpretations that lead to delayed or missed diagnoses. Participants develop a more nuanced understanding of ADHD presentations and contributing factors.

This module outlines the comprehensive clinical process required for accurate ADHD diagnosis, emphasising that no single test is sufficient. It explains DSM-5-TR diagnostic criteria, including symptom thresholds, early onset, functional impairment, and the need for evidence across multiple settings.

Participants learn about multi-informant assessments, including input from parents, teachers, and individuals, as well as the importance of developmental history and clinical observation. The module also covers differential diagnosis and comorbid conditions, helping distinguish ADHD from anxiety, depression, autism, and other overlapping conditions. This ensures a clear and accurate understanding of how ADHD is identified in practice.

This module introduces a multimodal, evidence-based approach to ADHD management, combining pharmacological and non-pharmacological interventions. It explains how stimulant and non-stimulant medications work, their effectiveness, and their role in improving both symptoms and overall quality of life.

In addition, the module explores psychosocial interventions such as behavioural parent training, cognitive behavioural therapy, and school-based strategies. It also highlights the importance of lifestyle factors, including sleep, exercise, and nutrition, as supportive elements in ADHD management. Participants gain practical tools and strategies to support individuals with ADHD across different environments.

This module consolidates all key learning from the programme, reinforcing ADHD as a valid, neurobiological, and highly treatable condition supported by extensive scientific evidence. It revisits major concepts from each module and integrates them into a cohesive understanding.

A strong focus is placed on challenging myths and reducing stigma, helping participants replace misconceptions with evidence-based knowledge. The module also emphasises real-life application, encouraging participants to translate learning into practical strategies for home, school, or professional settings. It concludes with guidance on next steps, ongoing support, and maintaining long-term positive outcomes.
