A client of mine who is a mother recently shared something with me that many parents, partners and family members of adults with ADHD will recognize. “I’ve stopped believing her.”
She wasn’t talking about dishonesty. She was talking about promises.
Her adult daughter would promise to phone, promise to visit, promise to complete an important task, promise to reply to a message—and she genuinely meant every word. Yet, more often than not, the promise wasn’t kept.
Messages would go unanswered for days. Important items would disappear. Deadlines would be missed. Tasks that seemed straightforward to everyone else somehow remained unfinished. At the same time, her daughter never seemed idle. She was constantly busy, juggling multiple things at once—driving or working while listening to a podcast at double speed, starting several complicated construction projects and struggling to finish, working three jobs and being extremely detail-oriented in some ways, moving quickly from one activity to another.
From her mother’s perspective, it looked like carelessness. Or perhaps poor priorities. Eventually, she found herself asking painful questions.
- “If she really cared, wouldn’t she make more of an effort?”
- “Can I trust anything she says?”
Those questions are understandable. They are also questions that often emerge when we interpret neurodivergent behaviour through a neurotypical lens.
Learning about ADHD didn’t erase the challenges in their relationship. It did, however, completely change how this mother understood her daughter.
Instead of seeing repeated disappointments as a lack of love or respect, she began to recognize the reality of a differently wired nervous system. That shift changed everything.
Understanding ADHD in Relationships: Medical Model vs Neurodiversity
For many years, ADHD has primarily been understood through what is known as the medical model. This model focuses on symptoms, deficits and impairments that require treatment. That perspective remains valuable. ADHD can significantly affect education, employment, relationships, finances and mental health. Many people benefit enormously from medication, coaching, therapy and practical supports.
Alongside this understanding, another perspective has gained increasing recognition: the neurodiversity model. Rather than viewing neurological differences solely as disorders to be fixed, the neurodiversity perspective recognizes that human brains naturally vary. ADHD represents one form of this variation. It comes with genuine challenges, but it also brings unique strengths.
Seeing ADHD through a neurodiversity lens does not minimize the difficulties people experience. Instead, it invites us to ask a different question. Rather than asking, “What’s wrong with this person?” we begin asking, “How does this person’s brain work?” That distinction matters enormously in relationships.
ADHD Is an Interest-Based Brain
One of the most helpful ways to understand ADHD is to recognize that it is not simply an attention problem. It is a motivation system that works differently. Many neurotypical people operate largely from what researchers describe as an importance-based nervous system. They can prioritize tasks because they recognize their future importance. Paying bills, replying to emails or booking appointments may not be enjoyable, but future consequences provide enough motivation to get them done.
The ADHD nervous system often works differently. It is far more interest-based. Tasks become easier when they are interesting, novel, personally meaningful or urgent. Conversely, tasks that feel repetitive, emotionally flat or important primarily to someone else may feel almost impossible to initiate—even when the person desperately wants to complete them.
This is why well-meaning advice such as “just try harder” or “be more organized” is often ineffective. The difficulty is not a lack of caring. It is a difference in how the brain activates motivation.
Why People with ADHD Often Work Best Under Pressure
Many people with ADHD find themselves completing an entire project the night before it is due. To outside observers, this looks like procrastination and unnecessary stress.
In reality, urgency creates the level of stimulation the ADHD brain often needs to engage fully. The approaching deadline increases dopamine availability, allowing focus and sustained attention that may have been unavailable days earlier. This doesn’t make procrastination enjoyable. Most ADHDers would much prefer to begin earlier. But understanding this pattern helps us replace moral judgement with curiosity.
The PINCH Principle: How ADHD Motivation Works
Many ADHD clinicians use the acronym PINCH to describe the conditions that naturally activate an ADHD nervous system.
P – Passion and Play
Tasks connected to personal meaning, enjoyment or creativity become much easier to sustain. Even adding playful elements to routine tasks can make a remarkable difference.
I – Interest
Interest fuels attention. This is why many ADHDers develop extraordinary expertise in subjects they love and can spend hours immersed in learning.
N – Novelty
The ADHD brain responds well to variety and fresh experiences. Small changes in routine can significantly increase engagement.
C – Competition, Collaboration and Challenge
Working alongside another person—a strategy known as body doubling—often makes difficult tasks feel manageable. Healthy competition or the right level of challenge can also increase motivation.
H – Hurry
Urgency provides stimulation. Breaking large projects into several smaller deadlines can often be far more effective than relying on one distant due date.
Notice that none of these strategies depend on shame, criticism or increasing pressure. They work because they align with how the ADHD nervous system naturally functions.
The Hidden Strengths of the ADHD Brain
Conversations about ADHD understandably focus on difficulties. Yet an interest-based nervous system also brings remarkable strengths. Many ADHDers are deeply curious, highly creative and exceptionally innovative. They often make connections between ideas that others overlook. Their enthusiasm can be contagious. When something genuinely captures their attention, they may enter periods of intense concentration—known as hyperfocus—during which they produce extraordinary work. Many entrepreneurs, inventors and creatives describe this way of thinking as one of their greatest assets. The same nervous system that struggles with administrative paperwork may excel at solving complex problems or generating original ideas. Other professions in which ADHDers thrive are emergency responders (firefighters, paramedics), healthcare (nursing, ER doctors), and creative/media roles (journalists, graphic designers). These roles leverage ADHD strengths like quick thinking, adaptability, and hyper-focus.
How Understanding ADHD Improves Relationships
The mother I mentioned earlier still experiences disappointment. Her daughter still forgets things. She still occasionally misses deadlines. She still sometimes disappears for a day or two when overwhelmed. But her mother no longer interprets these behaviours as evidence that she is unimportant. Instead, she recognizes that her daughter is navigating a nervous system that works differently—and, at present, one that is also experiencing burnout. Understanding has not removed the need for boundaries or accountability. It has changed the story she tells herself.
She has become more realistic about what her daughter can consistently manage. They now communicate more openly about reminders, overwhelm and expectations. Compassion has replaced many of the assumptions that once fuelled conflict.
Understanding doesn’t necessarily change another person’s behaviour. It changes the meaning we attach to that behaviour. And that can transform a relationship.
In Part 2 of this post, we’ll explore why ADHD in girls and women is so often overlooked, why many spend years believing they are simply anxious, disorganized or “too much,” and how understanding the female presentation of ADHD can bring enormous relief—to women themselves and to the people who love them. Read Part 2 here.
In Part 3 of this ADHD series, we will take a look at impulsivity in women, from overspending to emotional reactions, and how understanding the ADHD brain can replace frustration and judgment with compassion and practical strategies for creating a pause between impulse and action. Read Part 3 here.
