I’ve noticed a remarkable phenomenon over the last 20 years: Stimulant medication enhances empathy for many adults with ADHD. How is this possible? What is the connection among ADHD, empathy, and dopamine?
This post tackles the topic from several angles:
1. Defining empathy (it’s not what most people think).
2. Excerpting a passage on empathy and relationships from Is It You, Me, or Adult A.D.D.?
3. Sharing details from yet another study pointing to a connection between dopamine and cognitive empathy. (I’ll define cognitive empathy in a minute.)
A sneak preview of the study: It confirms my observation that stimulant medication often enhances empathy in people with ADHD.
But wait. This happens not because the medication “creates empathy.” Rather, the medication enhances dopamine transmission. That, in turn, allows some people with ADHD to focus on and access this “higher order” brain function. In fact, it is one they have always possessed but haven’t been able to reliably access.
Empathy sounds simple. But it’s really a complex phenomenon. Hang in there. The concept should become more clear as you keep reading.
Empathy is Not Sympathy, Forgiveness, or Compassion
Many people confuse empathy with other behaviors—sympathy, kindness, compassion, and the like. Empathy is not those things, though it might accompany them.
The most commonly accepted understanding of empathy is the quality that lets us “get in another person’s head.” When we empathize, we momentarily step outside of our own needs, thoughts, and desires. We contemplate what another person might be feeling.
In other words, there is a difference between empathy and “relating to.”
For example, if you have ever been in a bad car accident, for example, you are probably better able to relate to the experiences of other people who survive crashes. You “know how it feels.” But what if you’ve never been in an auto accident? What is the mental process that allows you to imagine what it is like for someone else?
That is a very simple example, but it is meant to drive home the point: Empathy is what allows us to imagine what another person is feeling, even if we’ve never been in that situation ourselves.
Moreover, empathy can allow us to step back from our own emotions, in trying to understand the mindset of a person who is disagreeing or even opposing us.
- Empathy is not compassion or kindness, not exactly. And it’s not sympathy.
- Contrary to widespread misperception, having empathy for a person is not forgiving that person or letting someone off the hook.
- On the simplest level, empathy is simply being able to “understand where that person is coming from. “
The cognitive scientists have terms for various types of empathy. But the one we’re most familiar with is called cognitive empathy. It simply means this: Imagining how the other person feels and what they might be thinking. It’s also called perspective-taking. Walking in another person’s moccasins.
Book Excerpt: ADHD and Empathy Impairments
Being able to empathize is key to successful negotiations, including in personal relationships. It can also help us understand why humans do some of the horrible things they do—and, with any luck, helping them to act in more humane ways.
Impaired empathy often destroys relationships where ADHD symptoms go unrecognized or unaddressed.
But deficits in empathy cut both ways in ADHD-challenged relationships. Both partners become more mutually empathic, once they both start learning about the many manifestations of ADHD.
Consider this excerpt from my book, Is It You, Me, or Adult A.D.D.?. In it, I name”low empathy” as one of three common ADHD-related deficits that can derail relationships:
3. Low empathy: “All take and no give”
“My wife seems to have empathy for movie characters, stray animals, or the grocery store clerk,” Alex offers. “But when it comes to her husband and teenage daughter, she often acts downright self-centered.”
Actually, empathy involves two sets of skills, according to [psychologist Robert] Brooks:
- The ability to take the perspective of another person
- The ability to understand and identify emotions
Yet, for many people with ADHD, the world can seem so chaotic and their focus so erratic, they don’t even know what they feel, much less what someone else feels.
Even if an adult with ADHD possesses both sets of empathic skills listed above, the person’s impulsivity or rigidity might obscure seeing the world through another’s eyes.
“And if a person is lacking in empathy,” Brooks adds, “he or she is likely to misread a situation and misunderstand the intentions of others. They often expect others to adapt to them, but they aren’t as willing to change themselves.”
It could be that change seems impossible—and the resulting feeling of powerlessness frustrates them even more.
In general, we can’t assume that all humans are capable of “normal” levels of empathy. Empathy is largely a function of the brain, and we all have different capacities.
Treating ADHD with medication often enhances the ability to act empathically. Certain coexisting conditions, however, such as Asperger’s Syndrome, complicate the picture.
[Don’t worry! Elsewhere in the book, I address the empathy deficits in the partners of adults with ADHD. But remember, some of them have ADHD, too.]
The Recent Study: Dopamine and Fair-Mindedness
The study from the University of California, Berkeley, published in Current Biology, isn’t the first to examine the effects of dopamine’s effects in the brain when it comes to empathy.
For example, 0ne 2014 study, The dopamine D4 receptor gene shows a gender-sensitive association with cognitive empathy: evidence from two independent samples, showed that gender plays a role in cognitive empathy. Interesting, eh?
This study is particularly relevant to ADHD, because this D4 gene variant has been associated with (but is not exclusive to) ADHD.
Women carriers of a certain gene variant (the 7R-allele) scored higher in cognitive empathy than female noncarriers. In men, however, those with the 7R variant scored lower than than men who did not have it.
The UC-Berkley researchers took a different approach in their paper: Dopamine Modulates Egalitarian Behavior in Humans.
Study Details: Follow the Money
Study participants, on two separate visits, received a pill containing either a placebo or a medication called tolcapone.
(Tolcapone prolongs the effects of dopamine, a neurotransmitter associated with reward and motivation in the brain. Stimulant medications such as Ritalin and Vyvanse also target dopamine; they slow the re-uptake of dopamine at the synapse, the gap between neurons. Tolcapone works a bit differently. This FDA-approved drug is used to treat people with Parkinson’s disease, a progressive neurological disorder affecting movement and muscle control, which are also affected by dopamine.)
This double-blind study of 35 participants, including 18 women. Neither participants nor study staff members knew which pills contained the placebo or tolcapone.
Participants then played a game in which they divided money among themselves and an anonymous recipient.
The result: Participants receiving tolcapone divided the money with the strangers in a fairer, more egalitarian way, compared to participants who received the placebo.
Medication Increased Sensitivity to Inequality
According to the press release at the UC-Berkley website, “Altering brain chemistry makes us more sensitive to inequality”:
By connecting to previous studies showing that economic inequity is evaluated in the prefrontal cortex, a core area of the brain that dopamine affects, this study brings researchers closer to pinpointing how pro-social behaviors such as fairness are initiated in the brain.
“We have taken an important step toward learning how our aversion to inequity is influenced by our brain chemistry,” said the study’s first author, Ignacio Sáez, a postdoctoral researcher at the Haas School of Business. “Studies in the past decade have shed light on the neural circuits that govern how we behave in social situations. What we show here is one brain ‘switch’ we can affect.”
The researchers also say that future research may lead to a better understanding of the interaction between altered dopamine-brain mechanisms and mental illnesses, such as schizophrenia or addiction, and potentially light the way to possible diagnostic tools or treatments for these disorders.
“Our hope is that medications targeting social function may someday be used to treat these disabling conditions,” said Andrew Kayser, a co-principal investigator on the study, an assistant professor of neurology at UC San Francisco and a researcher in the Helen Wills Neuroscience Institute at UC Berkeley.
This is a small study, one that remains to be replicated.
(I’m not sure what to make of the fact that it was jointly sponsored by the school of business and the neuroscience center, with funding from sources including the Defense Department.)
But the study adds to the increasing body of research around the role of dopamine and so-called “pro-social” behaviors such as fairmindedness and empathy.
Now, what about you?
What has been your experience of empathy as it relates to ADHD?
If you have ADHD, or if your loved one does, have you seen empathy impairments or enhanced abilities to empathize with medical treatment?
Or maybe you’ve seen something else entirely.
