ADHD 101 

Written by: Gabrielle Lau

ADHD is the text in the image. It represents Attention Deficit Hyperactivity Disorder. The image also includes colorful pipe cleaners, flowers, and other decorative elements to illustrate the concept of a busy or chaotic mind, often associated with ADHD.

ADHD is a neurodevelopmental disorder involving two main groups of signs and symptoms: impulsivity-hyperactivity and inattention. As such, when licensed professionals (physicians, psychologists, and other trained medical/social work personnel) diagnose the disorder, they distinguish between “inattentive type ADHD”, “hyperactive-impulsive type ADHD” and “ADHD-combined”.    

Possible signs and symptoms of Hyperactive-impulsive type ADHD

A question mark. It's a symbol used to indicate uncertainty, inquiry, or a request for information.
A person sitting on a chair. It's a simple icon often used to represent waiting, seating, or a general human figure.
  • Trouble sitting still
A no-talking or silence symbol. It's a combination of a circle with a diagonal line through a speech bubble and an exclamation point. This icon is commonly used to indicate a quiet zone or a request for silence.
  • Interrupting others while they are speaking
A shushing gesture. It's an icon that represents a person with their finger placed over their lips, indicating a request for silence or secrecy.
  • Blurting out when expected to be quiet
A person running. This icon is often used to represent speed, movement, or action. The lines behind the figure suggest rapid motion.
  • Running or climbing when not appropriate to do so
A fidget spinner. It's a popular toy with a central bearing and three spinning arms. It's often used for stress relief or entertainment.
  • Fidgeting/squirming
An hourglass. It's a symbol representing time, particularly the passage of time or a limited amount of time. The sand flowing through the hourglass signifies the irreversible nature of time.
  • Trouble waiting for their turn
An exit sign. It's a symbol commonly used to indicate an emergency exit or a way out of a building or area. The figure running towards the arrow suggests a quick and urgent departure.
  • Always seeming “on the go” or appearing “driven by a motor”

Possible signs and symptoms of Inattentive type ADHD:

A question mark. It's a symbol used to indicate uncertainty, inquiry, or a request for information.
A person searching for answers. The image shows a person with a question mark above their head, holding a magnifying glass. It symbolizes the act of seeking information, solving a problem, or investigating a mystery.
  • Losing things often/easily
A person experiencing confusion or frustration. The image shows a person holding their head with one hand, while a question mark appears in a speech bubble above their head. This combination suggests a state of bewilderment, uncertainty, or exasperation.
  • Forgetfulness
A person overwhelmed by noise and communication. The image shows a person sitting at a computer with their hands covering their ears. A loudspeaker and a speech bubble are nearby, symbolizing the overwhelming noise and communication they're trying to avoid.
  • Often easily distracted 
A person facepalming. It's a gesture often used to express frustration, embarrassment, or disbelief. The image shows a person covering their face with their hand, indicating a strong emotional reaction.
  • Making mistakes that seem “careless”
Sisyphus pushing a boulder uphill. This image references the Greek myth of Sisyphus, who was condemned to eternally roll a boulder up a hill, only for it to roll back down, repeating the task endlessly. It symbolizes the futility of effort or the struggle against insurmountable odds.
  • Challenges with organizing materials or deadlines
A person giving up on their goals. The image shows a person sitting on the bottom step of a staircase with a "no" symbol above their head. A trophy sits atop the stairs, symbolizing success or achievement. The image suggests that the person has given up on their aspirations or has lost motivation to continue striving.
  • Failing to follow instructions

Other possible Signs and Symptoms of both types of ADHD:

A question mark. It's a symbol used to indicate uncertainty, inquiry, or a request for information.
Overwhelmed and stressed. The image shows a speech bubble with tangled lines, symbolizing confusion or stress. A lightning bolt and an exclamation mark within other speech bubbles represent sudden or unexpected events or challenges. The overall image suggests a feeling of being overwhelmed or bombarded with problems.
  • Difficulty starting, stopping or transitioning between tasks, especially those requiring concentration
A person looking in a mirror. The image shows a person's profile facing a mirror, with their reflection visible inside the mirror. This is a common symbol of self-reflection, introspection, or personal evaluation.
  • Feelings of low-self esteem or self-defeating thoughts
Negative feedback or criticism. The image shows a person with an exclamation mark above their head and a thumbs-down icon nearby. This combination suggests that the person is receiving negative feedback, disapproval, or criticism.
  • Sensitivity to criticism, strong desire to not let people down
A person with a cane walking alongside a clock. This image likely represents a visually impaired person using a cane to navigate with time as a factor. It could also symbolize the importance of being punctual or time-conscious, even for those with disabilities.
  • Time blindness i.e., losing track of time
The five senses and the mind. The image shows a person with five circles above their head representing the five senses: sight, hearing, taste, touch, and smell. A brain symbol is also included, representing the mind or cognitive function. This combination suggests the interconnectedness of the senses and the mind in perceiving and understanding the world.
  • Feelings of sensory overload by sights, smells, sounds, textures, or tastes; or the opposite experience of not enough stimulation in the environment
Insomnia or sleep disturbance. The image shows a person in bed with lightning bolts above their head, indicating restlessness or anxiety. A clock nearby suggests the struggle to fall asleep or stay asleep. This combination is often used to represent insomnia or other sleep disorders.
  • Trouble sleeping

It is important to note that you do not have to have every symptom to be diagnosed with ADHD and this is not an exhaustive list of symptoms. This list is not a diagnostic tool and if you suspect your child has ADHD you should see a licensed professional physician or psychologist.  

A doctor. The image shows a person wearing a doctor's coat and stethoscope, which are common symbols of the medical profession.
A key inside a human head. This image typically symbolizes unlocking potential, understanding, or solving a problem. The key represents the solution or answer, while the head signifies the mind or intellect.

Stigma and Stereotypes

In the last 20 or so years, discussions surrounding ADHD have become more positive than in the past and the stigma has reduced overall. However, stereotypes, “urban myths”, and the media often perpetuate negative associations with ADHD and promote misinformation. Examples of negative stereotypes include: students with ADHD are always “the bad kid” in class; people with ADHD are “not as smart as others”; and that people with ADHD are just “lazy”. Experimental and anecdotal evidence counteract these stereotypes by showing that someone with ADHD may or may not show obvious symptoms – they may be the loudest OR the quietest in the class, or anywhere in between. ADHD is also independent from intelligence and people with the diagnosis are found in every occupational field. Lastly, studying the ADHD brain and experience with rigorous scientific processes has disproved that laziness has anything to do with the disorder. It is a fundamental difference in the structure and function of the brain that causes ADHD and the struggles are apparent whether or not they desire to do whatever it is they are doing.

ADHD superpowers

Emerging evidence from studies in psychology and education show that people with ADHD are characteristically: 

A superhero or hero figure. The image shows a person with a cape, flying through the air. This is a common symbol of heroism, courage, or the ability to overcome challenges.
Two people hugging. This image represents a gesture of affection, support, or friendship. It often symbolizes comfort, closeness, or empathy.
  • Intuitive and empathetic: While ADHD can cause emotional challenges for diagnosed individuals, they are often highly in tune with how others are feeling and be sensitive to changes in others’ emotions that may go unnoticed by  non-ADHD individuals.
Creativity and innovation. The image shows a cloud with various art supplies like a pen, pencil, paintbrush, and ruler, along with a rocket launching from it. This combination represents the concept of creativity, inspiration, and the ability to launch new ideas or projects.
  • Creative and innovative: In a brain with ADHD the rapid flow of thoughts and ideas allow individuals to think outside of the box and become skilled problem-solvers.
A person jumping or leaping. The image shows a stick figure-like person in mid-air, with their legs bent and arms outstretched. The curved line beneath them suggests the momentum of their jump.
  • Energetic and enthusiastic: People with ADHD, especially those with  hyperactive-impulsive type, have loads of energy that, when channeled properly, allows for enthusiastic engagement and a strong sense of determination.
A target. It's a circular symbol with concentric rings and arrows pointing towards the center. Targets are often used to represent goals, objectives, or something to aim for.
  • Hyperfocus: While ADHD is often associated with distractibility, many individuals experience periods of intense focus (hyperfocus) when they are deeply interested in something. This allows them to excel in tasks that capture their attention, from creative projects to technical skills.

These strengths show that ADHD isn’t just a collection of challenges but can also be a source of unique abilities when understood and nurtured properly.

Mythbusters: ADHD in Boys and Girls

Contrary to some popular beliefs, ADHD occurs in populations of all genders, races, ages, and socioeconomic brackets. When it comes to ADHD in girls compared to ADHD in boys…

No brainwashing. The image shows a magnifying glass with a brain inside crossed out by a red X. This symbolizes the prevention or prohibition of manipulating or controlling people's thoughts or beliefs.
A pair of hands forming a frame. This image is often used to represent framing a photo or scene, focusing attention on a particular subject, or symbolizing the act of capturing or creating something.

Myth #1: Boys have ADHD way more often than girls.

Fact: While boys are diagnosed with ADHD more often, it’s not because they have it more. Girls often go undiagnosed or diagnosed later in life because their symptoms tend to be less overt and more inattentive (e.g., daydreaming, struggling with focus) than the hyperactive or impulsive behaviours boys often show.

A person with a question mark inside their head. This image represents confusion, uncertainty, or a need for information. The question mark inside the head symbolizes the internal query or doubt.

Myth #2: ADHD looks the same in boys and girls.

Fact: ADHD can present differently between genders. Girls are more likely to show internalized symptoms like being forgetful or easily distracted, while boys may exhibit more externalized behaviours like fidgeting and acting out. These subtle differences lead to under diagnosis in girls.

Overwhelmed and anxious. The image shows a person sitting with their knees pulled up to their chest, surrounded by lightning bolts. This represents a feeling of being overwhelmed, stressed, or experiencing anxiety. The lightning bolts symbolize the intensity of these emotions.

Myth #3: Girls with ADHD aren’t as affected as boys.

Fact: Girls with ADHD can experience just as much difficulty as boys but may express it differently. Undiagnosed or untreated ADHD can lead to issues with self-esteem, anxiety, and academic performance in girls.

A video game controller. It's a handheld device used to control video games, typically with buttons, joysticks, and triggers.

Myth #4 Boys only exhibit Hyperactive-Impulsive type ADHD

Fact:  Boys often go undiagnosed as they are not hyperactive but in fact experience inattention in the classroom and at home.  Just like girls, they may have difficulty paying attention or they might hyper focus on something positive like reading or something less positive like gaming.   They also may forget things and lose important items or are often late and have a limited sense of time.  

A person celebrating or rejoicing. The image shows a person with their arms raised in the air, indicating joy, excitement, or victory.

Myth #5 Girls do not have Hyperactive-Impulsive type ADHD

Fact:  Signs of hyperactivity in  girls are often different from boys. They may be chatty and talkative and interrupt or change topics mid sentence.   They may be described as a “tom boy” because they like physical activity.   They may also be overly emotional or get excited very easily. 

Two people helping each other. One person is standing on a platform, reaching down to help another person who is trying to climb up. This image represents assistance, cooperation, or teamwork.

ADHD doesn’t discriminate! Boys and girls can both experience it, but understanding the differences in how it presents helps ensure everyone gets the support they need.   In our next blog on ADHD we will discuss what to do after a diagnosis.   

If you suspect your child has ADHD you should see a licensed professional physician or psychologist.  

Two people having a conversation. The image shows two people sitting in chairs, facing each other with a speech bubble between them. This represents communication, discussion, or a meeting.
