What is ADHD?
There are many different thoughts and theories about what ADHD is and what it isn't.
As research on ADHD evolves, so does our thinking.
It means changes to the language we use and how we interpret and manage symptoms. If you are trying to understand ADHD symptoms in yourself or someone around you it is important to build an informed approach to living with ADHD by looking at a variety of information sources and checking for accuracy and context.
Current Medical Definition
ADHD is currently described as a neurodevelopmental condition associated with differences in attention, motivation, emotional regulation and executive functioning.
​
The diagnostic description can be found in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), a guide used by clinicians when assessing and diagnosing conditions such as ADHD.
​
​
Description of Symptoms
ADHD is often described in terms of symptoms, difficulties and differences from what is considered typical.
There are strengths that accompany ADHD, such as creativity, curiosity, problem-solving and the ability to think differently from those around you.
​
As well as core symptoms there are many everyday signs of ADHD.
​
Impact of ADHD
ADHD affects people in a wide variety of ways.
Some people experience only minor difficulties, while others find that work, relationships, confidence and everyday responsibilities become increasingly difficult to manage.​
The impact of ADHD can change in line with different life phases - such as work, family, health, age and hormones.
​
What Causes ADHD?
Shifts in Thinking
Our understanding of ADHD is evolving because new research continues to add to the picture.
For many people, understanding that ADHD is not caused by laziness, poor parenting or a lack of willpower is an important shift.
​
Helping to replace self-criticism with curiosity and develop a better understanding of an ADHD mind really works.
Biological Perspectives
Research suggests ADHD has a strong genetic component. Scientists have also identified differences in brain development and functioning, particularly in areas linked to attention, motivation, emotional regulation and executive functioning.
​​​​
Environmental Perspectives
Researchers continue to explore how factors such as early life experiences, stress, trauma, sleep and physical health may influence how ADHD develops or is experienced. The extent of these influences remains an area of ongoing discussion.​​
​
Evolutionary Perspectives
Others view ADHD as part of the natural variation found within human populations. Characteristics such as curiosity, novelty-seeking, adaptability and risk-taking may have offered advantages in different environments throughout human history, even if they can create challenges within modern systems.​​
Whatever perspective you find most helpful, understanding ADHD is often less about finding a single cause and more about understanding how it affects you as an individual.
