When most people hear “ADHD,” they picture a hyperactive young boy bouncing off the classroom walls, unable to sit still or stop talking. But the reality is far more nuanced.
ADHD (Attention-Deficit/Hyperactivity Disorder) is a complex neurodevelopmental condition that can look very different depending on a person’s age, gender, and the specific type of ADHD they have. Our tendency to view ADHD through a narrow lens means many people, especially girls, women, and inattentive types, are overlooked or misunderstood, sometimes for years.
Let’s break down the three types of ADHD, explore how they show up across the lifespan and in different genders, and consider the impact of these differences on people’s lives.
The Three Types of ADHD
ADHD isn’t a single set of symptoms. It’s actually diagnosed as one of three types, based on which traits are most prominent:
Predominantly Inattentive Type (ADHD-I): Trouble focusing, forgetfulness, and disorganisation are the main features here. People with this type are often quiet, daydreamy, and may not show obvious signs of hyperactivity.
Predominantly Hyperactive-Impulsive Type (ADHD-H): This type is marked by high energy, impulsive actions, and difficulty sitting still. These are the classic “bouncing off the walls” behaviours.
Combined Type (ADHD-C): The most common, especially in children, this type includes significant symptoms of both inattention and hyperactivity-impulsivity.
How ADHD Looks at Different Ages
Children
In primary school, ADHD symptoms often stand out. Boys are more likely to be diagnosed because their hyperactive and impulsive behaviours, fidgeting, running around, blurting out answers, are disruptive and hard to miss. Girls, on the other hand, are more likely to have the inattentive type: they might be quietly daydreaming, losing things, or struggling to follow instructions, but they’re less likely to cause a scene. As a result, many girls fly under the radar, their struggles dismissed as “shyness” or “laziness”.
Teenagers
As kids move into adolescence, the picture shifts. Hyperactivity may become less obvious, replaced by inner restlessness or impulsive risk-taking. Teens with inattentive ADHD might fall behind academically, not because they’re not smart, but because they miss details, forget assignments, or can’t organise their workload. Socially, impulsivity can lead to trouble with friendships or risky behaviour. Girls with ADHD in their teens are still less likely to be diagnosed, but may experience anxiety, low self-esteem, or challenges with peer relationships.
Adults
ADHD doesn’t go away with age, but it can change shape. Adults with inattentive ADHD might struggle with chronic disorganisation, missed deadlines, and forgetfulness, which can impact their careers and relationships. Hyperactive-impulsive symptoms may show up as impatience, talking over others, or making snap decisions. Women are often diagnosed later in life, sometimes only after their own child is diagnosed, as they realise their lifelong struggles with focus and organisation weren’t “just being scatterbrained” after all.
Gender Differences: Why Girls and Women Are Missed
Research shows that boys are more likely to be diagnosed with the hyperactive-impulsive or combined types, while girls and women are more likely to have inattentive ADHD. This difference matters. The classic ADHD stereotype is loud and disruptive, traits more common in boys, so girls who are quietly struggling are often overlooked. They may internalise their difficulties, leading to anxiety, depression, or low self-worth. Even when girls and women are diagnosed, it’s often much later, after years of feeling “not good enough” or being labelled as lazy or disorganised.
The Impact of a Narrow View
When we only recognise the “hyperactive boy” version of ADHD, we miss countless others who need support. This narrow view can have real consequences:
Delayed Diagnosis: Girls, women, and inattentive types may go undiagnosed for years, missing out on early intervention and support.
Misunderstanding and Stigma: People with less visible symptoms are often misunderstood by teachers, employers, and even family members.
Mental Health: Undiagnosed ADHD can lead to anxiety, depression, and low self-esteem, especially in those who internalise their struggles.
Why a Broader Perspective Matters
Understanding the different types of ADHD, and how they show up across ages and genders, means more people can get the help they need. It’s not just about recognising the loudest or most disruptive behaviours; it’s about seeing the quiet daydreamers, the overwhelmed teens, and the adults who’ve spent a lifetime feeling “not quite together.”
If you suspect ADHD in yourself or someone you care about, don’t rely on stereotypes. Seek a professional assessment that takes into account the full range of symptoms and how they impact daily life.
