Is impulsivity more common in children or adults with ADHD? 

Impulsivity in children and adults with ADHD is a core symptom, but its manifestation can differ significantly across age groups. While impulsivity is commonly associated with children, it also affects adults with ADHD, though in different ways. So, is impulsivity more common in children or adults with ADHD, and how does it vary across developmental stages? 

Impulsivity in Children 

For children with ADHD, impulsivity is often seen as impulsive behaviour such as interrupting others, acting without thinking, or struggling to sit still in class. Children may find it difficult to wait their turn, blurt out answers, or engage in risky behaviours without considering the consequences. Age differences in ADHD play a role here; young children are still learning to regulate emotions and actions, making impulsivity a more visible trait. 

Impulsivity in Adults 

In adults with ADHD, impulsivity in children and adults can appear more subtle. While they might no longer interrupt conversations as often, impulsivity can still affect decision-making, finances, relationships, and work. Adults may struggle with impulse control when making hasty career choices, spending decisions, or reacting emotionally in stressful situations. As the individual matures, impulsivity becomes more internalised, leading to greater frustration or feelings of being overwhelmed. 

Key Differences Between Children and Adults 

The age differences in ADHD play a major role in how impulsivity manifests. In children, impulsivity is often external, visible in physical actions and verbal outbursts. In contrast, adults may experience internal struggles with decision-making and self-control, which can have long-term consequences in their personal and professional lives. 

In conclusion, impulsivity in children and adults is a common symptom of ADHD, but it presents differently depending on age and developmental stages. While it is typically more noticeable in children, adults with ADHD continue to experience impulsivity in more nuanced ways.
