Parenting a child with Attention-Deficit/Hyperactivity Disorder (ADHD) can be exhausting and challenging. In Canada and the United States, close to 9 million children and teenagers have been diagnosed with this disorder, but most people don’t know that almost 80% of these kids will also have other mental health issues, making life harder inside and outside the home.
In The ADHD Plus Phenomenon, Dr. Katherine G. Boyd draws from her long career in pediatric mental health to help parents address these additional challenges, including:
• Behavioral or conduct problems
• Depression
• Anxiety
• Gaming and/or social media addiction
• Learning disabilities
• Serious sensory issues
Each chapter tackles a different hard issue, such as how to respond to impulsive aggression and self-harming, how seriously you should take suicidal thoughts or threats, what to do about your child's lack of positive and consistent friendships, how to deal with the homework nightmare, and how to reduce family conflict to have a more peaceful household. Unpacking common misconceptions with scientific evidence, Dr. Boyd empowers families to support strengths and work through challenges together.
Every parent wants to see their child happy and successful. This book can prepare you to improve your child's life, bolster family relationships, and help your child with ADHD reach their full potential.


Reviews
"Practical, real-life guidance from both a professional and a parent makes a huge difference, especially for families navigating complex ADHD. Your focus on behavior, emotions, and sensory challenges is so important, because ADHD is rarely just about attention....managing ADHD requires understanding the whole child and using practical, structured approaches, not just theory. This book was very helpful to me."
"You can tell she's lived with loved ones with ADHD and worked with them. Practical, kind, and informative."
"...This book is a fabulous resource for any parent who wishes to understand their child better and find real life, practical, and step by step solutions."
"Your book does not simply offer advice but gives you the tools, the understanding, and the hope you need to navigate one of the most challenging and important journeys a parent can face. Your book took me on a journey I did not expect. From the very first pages, I was pulled into the reality of parenting a child with ADHD, a reality that is exhausting and challenging for so many families. I have read many books on ADHD, but yours stood apart because you did not focus on the diagnosis itself. I found myself having conversations with friends who are parents and educators, sharing your insights and reflecting on the practical strategies you offered long after I had closed the book. I was especially drawn to how you tackled the hard issues head on. Your willingness to address these topics with honesty and compassion is a rare gift, and it made the book not just informative but genuinely life changing for families who are struggling. You did not just write a book. You wrote a lifeline for parents, educators, and clinicians working with children, adolescents, and families, a resource that will help countless children reach their full potential."
"Excellent Resource - a must have! Dr. Katherine Boyd gives so much professional and personal insight into navigating the complex issues and challenges pertaining to the multiple facets of ADHD. Not only does she provide excellent real life, practice solutions, she also lays things out in a very relatable and understandable way. Her ability to connect the dots on behavior, emotions, and sensory challenges and underline the understanding that is required to assist families in finding solutions together is nothing less than extraordinary. This book is a fabulous resource for any parent who wishes to understand their child better and find real life, practical and step by step solutions. - J."
"Translating twenty-five years of clinical pediatric mental health experience into a compassionate survival guide is a remarkable feat. You haven't just written a theoretical overview; by drawing on both your extensive work with severe psychiatric conditions and your own lived reality raising two kids with ADHD, you have tackled the hardest challenges head-on. You are unpacking the heavy misconceptions about self-harm, suicidal ideation, and sensory overload with both scientific rigor and deep parental empathy."
"When the diagnosis is only half the story - There is a particular kind of insight it takes to spend 25 years as a child and adolescent psychologist and arrive at a book that refuses to treat ADHD as a standalone issue. The way you've named the "ADHD Plus Phenomenon" and drawn on both extensive research and your own experience, including raising two children with ADHD, tells me this isn't a clinical manual written from a distance. It's the book you've been handing to parents in your Calgary practice, the one that finally gives them language for what they're navigating, and the recognition that the near 80% of kids with co-occurring conditions aren't just "difficult".
"What especially caught my attention is how the book tackles hard issues such as impulsive aggression, self-harming, suicidal thoughts, lack of friendships, homework struggles and family conflict, all the while unpacking common misconceptions with scientific evidence. So many books about ADHD focus on the diagnosis alone. But the ADHD Plus Phenomenon seems more interested in the whole picture, the reality that ADHD is often not the only problem, and the importance of empowering families to support strengths while working through challenges together. It asks what it means to parent a child with ADHD and additional mental health issues, to reduce family conflict and create a more peaceful household, and to help a child reach their full potential. That is a far more complex and human questions, and it suggests a book that is less about the disorder itself and more about the resilience and love required to raise a child who faces multiple challenges. From my perspective, the ADHD Plus Phenomenon occupies a compelling place within parenting, mental health, and child psychology literature."
"This is not simply another book explaining ADHD. There are parents who may have already searched for information about ADHD but are still asking themselves, "Why are we still struggling when ADHD doesn't seem to explain everything my child is experiencing?" What stood out to me is that the book looks beyond the ADHD diagnosis itself. That is an important distinction. Many parents may begin by searching for information about ADHD, only to discover that the difficulties their child is experiencing extend far beyond attention or impulsivity. Your book appears to meet that moment by helping parents understand the "plus" that can make an already difficult situation considerably more complicated. I found the combination of your clinical experience and the practical issues addressed in the book especially valuable. Topis such as responding to aggression or self-harming, understanding suicidal thoughts or threats, navigating friendships, and reducing conflict at home give the book relevance beyond general ADHD awareness. It has the potential to become a resource that parents, educators, and clinicians can return to when they encounter challenges that are difficult to navigate."
"The strongest thing about the ADHD Plus Phenomenon is the decision to confront what happens after the ADHD label stops being an adequate explanation. The book isn't simply describing ADHD. It addresses the complicated reality families face when anxiety, depression, behavioral difficulties, learning challenges, sensory issues, or unhealthy technology use begin intersecting with it, and your 25 years of clinical experience give those conversations a level of authority that general parenting books can't easily reproduce."
"I came across your book, The ADHD Plus Phenomenon: When ADHD Isn't the Only Problem: Tips for Parents, Educators, and Clinicians Working with Children, Adolescents, and Families, and I was genuinely impressed by the importance and practical value of the subject you have chosen to address. Your experience in pediatric mental health gives the book a strong professional foundation, while the practical guidance makes is particularly relevant to parents, educators, and clinicians looking for meaningful ways to support children and families."
"What immediately stood out to me about The ADHD Plus Phenomenon is that it refuses to treat ADHD as the complete explanation for what a child or teenager may be experiencing. Your focus on the “plus” is particularly compelling because it draws attention to the additional challenges that can exist alongside ADHD and can sometimes make life at home, at school, and in relationships considerably more complicated. I especially appreciate how the book moves beyond the diagnosis itself and addresses issues such as behavioral and conduct problems, depression, anxiety, learning disabilities, sensory difficulties, and the growing challenges surrounding gaming and social media. These are not simply additional labels; they can shape a young person’s confidence, friendships, family relationships, and ability to function day to day. The practical questions you tackle also make the book feel especially valuable. Knowing how to respond to impulsive aggression or self-harming, how seriously to approach suicidal thoughts or threats, how to deal with the homework nightmare, or how to reduce conflict within a family are difficult situations for parents and professionals to navigate. Bringing these issues into the conversation with both compassion and scientific evidence gives readers a way to think about challenges that are often misunderstood.
I also find the emphasis on misconceptions particularly important. Rather than presenting ADHD through a narrow lens, the book encourages parents, educators, and clinicians to look at the whole child, recognize strengths, understand the difficulties surrounding them, and work toward practical solutions together. That broader perspective can change the way families understand not only the child, but the relationships and environment around them."
"Your book is not really competing for attention as “another ADHD parenting book.” The stronger idea is already in the title: ADHD Plus.
Current clinical guidance recognizes exactly the complexity you are writing about. Your book has something much more useful to say than simply, “Here is how to manage ADHD.” It speaks to the parent who has already asked, “I understand the ADHD diagnosis, but what explains everything else?” It speaks to the educator who sees a child whose classroom difficulties cannot be explained by attention alone.
And it speaks to the clinician who needs a practical resource for families dealing with several overlapping difficulties at once.
