Types of impulsivity are crucial to understand when discussing ADHD, as impulsive behaviours manifest in various ways. While impulsivity is a hallmark symptom of ADHD, it isn’t just one uniform behaviour. In fact, there are distinct behavioural subtypes of impulsivity that impact both children and adults with ADHD. So, how do these different types of impulsivity show up, and how do they affect daily life?

Types of Impulsivity in ADHD 

Impulsivity in ADHD can be broken down into two primary categories: cognitive impulsivity and behavioural impulsivity. Let’s dive deeper into these subtypes and how they differ: 

Cognitive Impulsivity 

Cognitive impulsivity refers to quick, often unreflected thinking. People with ADHD may struggle to pause and think through decisions, leading to snap judgments and risky choices. This type of impulsivity can affect decision-making in everyday life, such as making purchases without consideration, rushing through tasks, or jumping into new projects without planning. It can also lead to challenges with problem-solving, as impulsive decisions often prevent individuals from thinking through all possible solutions. 

Behavioural Impulsivity 

Behavioural impulsivity is more outwardly visible and is characterised by actions taken without thinking. This includes interrupting conversations, speaking out of turn, or engaging in risky behaviours. Children with ADHD might be particularly affected by behavioural impulsivity, acting before thinking through the consequences of their actions. In adults, behavioural impulsivity might show up in actions like blurting out opinions or making quick, unplanned decisions that have lasting consequences. 

In conclusion, types of impulsivity, can both have a significant impact on individuals with ADHD. Recognising these subtypes is essential for better understanding ADHD and creating effective treatment plans.
