What Are the Core Symptoms of Hyperactivity in ADHD? 

Core hyperactivity symptoms in ADHD include behaviours such as impulsivity, fidgeting, and restlessness, which are typically characterised by a constant need for movement and difficulty staying still. These symptoms can interfere with daily life, affecting a child’s ability to focus, follow instructions, or engage in calm activities. Hyperactivity in ADHD is one of the primary symptoms and often manifests in various ways, particularly in social and academic settings, where sitting still and focusing for extended periods is required. 

The Role of Hyperactivity in ADHD 

Hyperactivity is often seen alongside other ADHD symptoms, such as impulsivity and inattention, contributing to challenges in regulating emotions and behaviour. The core hyperactivity symptoms of ADHD are most evident in children but can continue into adulthood, often appearing in different ways. Although hyperactive behaviours may be less visible in adults, symptoms such as restlessness and difficulty focusing often remain and can affect work, relationships, and daily life.  

How Core Hyperactivity Symptoms Manifest in ADHD 

This is how the core hyperactivity symptoms typically appear in individuals with ADHD: 

Impulsivity and Acting Without Thinking

A key symptom of hyperactivity in ADHD is impulsivity, the tendency to act without thinking about the consequences. This can include interrupting conversations, making abrupt decisions, or having difficulty waiting for one’s turn. This can lead to social challenges, misunderstandings, and problems in structured environments like school or work. 

Fidgeting and Inability to Stay Still 

Children and adults with ADHD often experience fidgeting and may have difficulty remaining seated in situations that require it, such as in class, meetings, or at the dinner table. They may tap their feet, twirl pens, or squirm in their seats. This can lead to difficulties in completing tasks, staying focused, and participating in quiet activities, which may disrupt social interactions and academic performance. 

Restlessness and Excessive Movement

Restlessness is a common symptom of hyperactivity, where the individual feels a constant need to move or be active. This can manifest as pacing, walking around, or engaging in repetitive motions. It is challenging for individuals with ADHD to relax, complete sedentary tasks, or engage in activities that require calmness, like reading or sitting through a meeting.
