Did you know ADHD can present differently in adults than in children?

Attention Deficit Hyperactivity Disorder (ADHD) is often thought of as a childhood condition. Many people picture a child who is constantly moving, interrupting, or struggling to sit still in class. While these signs are common in children, ADHD does not disappear with age. Instead, it changes how it shows up in daily life. Understanding these differences can help adults recognize their own challenges and seek support that fits their needs.

How ADHD looks in children

In childhood, ADHD symptoms are often more visible because of the structured environment children face. Schools expect students to sit still, listen, and complete tasks on time. Children with ADHD may:

Appear very active or restless, often fidgeting or leaving their seat
Act impulsively, interrupting conversations or acting without thinking
Struggle to focus on lessons or follow multi-step instructions
Have difficulty finishing homework or classroom assignments

These behaviours stand out because they clash with the rules and routines children must follow. Teachers and parents often notice these signs early, which can lead to diagnosis and support.

How ADHD changes in adulthood

As children with ADHD grow up, the outward signs often become less obvious. Physical hyperactivity tends to decrease, but other challenges remain or even increase. Adults with ADHD may experience:

Mental restlessness, feeling like their mind is always racing
Difficulty organising tasks and managing time effectively
Problems with focus, especially on long or boring tasks
Emotional ups and downs, including frustration or mood swings
Chronic feelings of overwhelm or fatigue from trying to keep up with daily demands

Many adults develop coping strategies to hide or manage their symptoms. For example, they might create detailed to-do lists, use reminders on their phone, or avoid situations that require intense focus. These strategies can mask ADHD, making it harder to recognize and diagnose in adulthood.

Why ADHD is often diagnosed later in life

Some adults only learn they have ADHD after years of struggling without understanding why. This is especially true for people who were academically successful or described as quiet and anxious children. Because their symptoms were less disruptive, their ADHD went unnoticed. However, the world has a much greater understanding of ADHD now, particularly with the influence of social media and increased awareness. Information about ADHD is more accessible, and conversations surrounding mental health have become more open, allowing individuals to recognise their symptoms and seek help.

Late diagnosis can bring relief and clarity. Adults may finally understand why they have faced certain challenges and how to address them. It also opens the door to support that respects their unique experiences.

The core features of ADHD remain the same

Despite the differences in how ADHD looks at different ages, the underlying traits stay consistent. These include:

Inattention: Difficulty sustaining focus or following through on tasks
Hyperactivity: Physical restlessness in children, mental restlessness in adults
Impulsivity: Acting without thinking or struggling to control emotions

Recognising that ADHD is a lifelong condition helps reduce stigma. It also encourages people to seek help that fits their current needs, whether they are children or adults.
