ADHD 2.0

ADHD 2.0: New Science and Essential Strategies for Thriving with Distraction—from Childhood through Adulthood was published by Ballantine Books in January 2021. A slim book of about two hundred pages.

The authors are familiar: Edward M. Hallowell and John J. Ratey, both psychiatrists, both people who, in their own words, have this attention trait themselves. With Driven to Distraction in 1994 and Delivered from Distraction in 2005 they became the most widely read duo in this field. This book is their third joint ADHD book, and the "2.0" in the title carries a claim of being an update.

I could not find a verified Turkish edition; I am writing it under its English name.

What the "2.0" label promises

The title says that new science has been added on top of the previous two books. As I read, I tried to separate what is really new from what is familiar.

What is new: a narrative built on brain networks, putting the cerebellum at the center, giving relationship and belonging such prominence as a component of treatment, and the name VAST.

What is familiar: the language of case narratives, the warm and encouraging tone, the tendency to bring out the opportunities of ADHD, the emphasis on exercise.

Making this distinction matters, because the phrase "new science" on the cover pushes the reader to read every claim in the book as a summary of current research. Yet part of the new sections rests on solid findings, and part on ideas for which the evidence has not yet formed.

A proposal for a name change: VAST

The first chapter of the book describes ADHD as a spectrum. Alongside distractibility, impulsivity and restlessness, the drive to create and to act is also counted as part of this spectrum.

Here the authors propose a new name: VAST, that is, Variable Attention Stimulus Trait. Roughly: a trait of variable attention and seeking stimulation. The logic behind the proposal is that the words "deficit" and "disorder" weigh on people, and that it is not possible to describe both the pluses and the minuses of the picture with a single word.

The book also speaks of how modern life pushes everyone toward a scatteredness resembling ADHD. It says that technology, constant notifications and speed produce similar symptoms in people who have no diagnosis.

When these two stand side by side in the same chapter, a problem arises. A clinical picture and a cultural fatigue come under the same roof. Reading as someone with a diagnosis, I felt that something that had impaired my functioning for years was being put in the same basket as everyone getting lost in their phones. The authors do make the distinction, but the general flow of the text blurs it.

The naming proposal itself is also open to debate. The word "trait" may reduce stigma. The same word may weaken your hand when you request accommodations at work or school.

The VAST trap for a reader without a diagnosis

Considering the wide readership of this book, there is one more risk.

A reader who cannot lift their head from their phone, who somehow cannot focus, but has not been diagnosed with ADHD, may find themselves inside VAST when they read this book. That in itself is harmless. The problem arises where the description of a trait starts to be used like a diagnosis.

An ADHD diagnosis requires that symptoms have persisted since childhood, appear in more than one setting and impair functioning. Cultural scatteredness does not meet any of these criteria on its own. The book says this, but the appeal of the VAST concept casts this warning into shadow.

The noise inside the head

The second chapter brings the most useful concept in the book.

It talks about two large networks in the brain. The task-positive network is the system that comes into play when you focus on a task. The default mode network is the one that runs when there is no external task, associated with inward-directed activities such as daydreaming and thinking about the past and the future.

In the authors' account, the switch between these two networks is problematic in ADHD: when a task begins, the default mode network does not quiet down enough. The result is thoughts that keep circling in the head while trying to focus on a task, self-criticism, imagining the worst.

This account touched a very familiar place in me. It gave me a language in which I could explain to myself why, at my desk, my mind goes back to a conversation from last night.

On the research side, this idea has a counterpart. There are brain imaging studies reporting differences in the suppression of the default mode network during tasks in groups with ADHD. But these are group averages and are not enough to explain an individual's experience. The book turns these findings into a persuasive story, and the story speaks more definitively than the finding itself.

I put my pen down at the cerebellum chapter

The third chapter is devoted to the cerebellum, the little brain. The authors describe this structure's relationship to ADHD and put forward that stimulating the cerebellum with balance and coordination exercises may ease ADHD symptoms. Tools such as the balance board are suggested; in interviews Hallowell also gives examples such as standing on one foot or sitting on a ball.

There is a serious evidence gap here.

The imaging studies showing that the cerebellum is one of the structures associated with ADHD are real. But this does not mean that balance exercises reduce ADHD symptoms. In an interview with Hallowell in the Carlat Report, the interviewer stated plainly that cerebellar training techniques have not shown efficacy in controlled studies. Hallowell, in the same interview, described himself as a storyteller and said he leaves the double-blind studies to others.

I find this answer honest. But then a contradiction remains between the promise of "new science" on the book's cover and this chapter.

The balance exercise harms no one. The harm lies in the possibility that the reader invests time and hope in this instead of treatments with strong evidence.

Connection and the right challenge

The fourth chapter describes the healing power of relationship and belonging. Suggestions such as family meals, friendships, one-on-one time with a child and gratitude are listed. The authors' calling connection a kind of vitamin is memorable.

The suggestions in this chapter are commonsensical and apt when you consider that people with ADHD are more open to social loneliness. There is just one point: the authors also touch on the relationship between adverse childhood experiences and the severity of ADHD. This relationship is real but its direction is complicated; ADHD symptoms themselves also raise the risk of adverse experiences.

The fifth chapter carries the idea I like most in the book: everyone finding their own "right challenge." People with ADHD get bored and scattered very easily at a job that is too easy, and freeze at a job that is too hard. The band in between is the place where skill and interest are stretched just right. The authors also point to not asking for help as one of the biggest obstacles to progress after diagnosis. Reading this did me good.

For me the right-challenge idea became more than a piece of advice on choosing a job. It helped me understand why, during the day, I lose myself in some tasks and freeze at others. My attention scatters on very familiar and repetitive tasks; I cannot start on tasks that look vague and enormous. Either making a task a little harder or breaking it into smaller pieces is the way to pull it into that band.

The research counterpart of this idea is limited. But as a working tool it is a harmless suggestion that can be tried without needing evidence.

Environment, movement, medication

The sixth chapter describes building structure at home, at school and at work: regular sleep, a daily schedule, screen limits, nutrition.

The seventh chapter is devoted to exercise. Here the book stands on firm ground; Ratey is someone who has written a separate book on movement and the brain. There are meta-analyses showing that exercise has a moderate effect on ADHD symptoms. I collected the details in the article on ADHD and movement.

The eighth chapter is devoted to medication and its tone is balanced. It explains that medication works for most people and that stimulant medication used early and correctly does not increase the risk of substance use. Here the authors also give space to the concept of rejection sensitive dysphoria. I recommend that the reader read it knowing that this concept is not in the diagnostic criteria and that its research base is still thin. The decision about medication is always made with a doctor.

The price of a slim book

The book's biggest advantage is its readability. Short chapters, warm language, case examples. A book that a reader with ADHD can actually finish.

That is also where its price lies. When brain networks, the cerebellum, connection, environment, exercise, medication and a naming proposal are squeezed into two hundred pages, every subject stays on the surface. The point critics often raise is that a significant portion of the claims are not tied to a particular study within the text. Even the claims that are correct often pass without a source, and the reader cannot tell which are solid and which are the authors' clinical intuition.

The book's stance on heritability, on the other hand, is apt; it accepts that ADHD has a strong genetic component.

Where are the women

Looking at the chapter structure, there is no chapter devoted to ADHD in women.

For a book written in 2021 this is striking. In the last twenty years it has been discussed more and more that ADHD in women can look more inward, that masking delays diagnosis, and that hormonal periods such as the menstrual cycle and menopause can affect symptoms. These were the subjects that would have fit most comfortably under the "new science" title.

Reading the book as a woman, I felt this gap. I found myself in much of the scatteredness described, but I could not find the story of being noticed late, of wandering for years among other diagnoses.

Kinship with the superpower shelf

In the books of Hallowell and Ratey there has always been a tendency to see ADHD as a talent. ADHD 2.0 is the book where this tendency is most visible. The Ferrari engine and bicycle brakes analogy appears here too.

I discussed at length what this frame does in the article on the question of strengths in ADHD. In short: it reduces shame, and in doing so it risks lightening the difficulty.

It is only fair to say that the book does not sell ADHD as an outright gift. It plainly writes about the cost of the unmanaged picture, the risk of addiction, the need for medication. Still, from the cover to the last page, the energy of the text is on the side of opportunities.

For whom, in what order

A good door for someone newly diagnosed, who thinks of themselves as lazy or broken, and who does not have the strength to read a heavy book. It can be finished in a short time and it gives the reader hope.

For the parent of a child with ADHD, the environment and connection chapters are also useful.

If you are looking for information, it is not enough alone. This book needs to be read together with a book that gives sources and states its limits; otherwise you cannot tell which suggestion rests on evidence and which on the authors' belief.

As a reading order I recommend the first two chapters and the fifth. If you are going to read the third chapter, read it keeping in mind the difference between a claim and a finding. The seventh and eighth chapters are also short and useful.

If you have read Driven to Distraction, the narration here will feel familiar to you; what is new is the narrative built on brain networks and the cerebellum.
