Hyperactive-impulsive ADHD is one of the three subtypes of ADHD, characterised primarily by restlessness and impulsivity. Unlike the inattentive type, which is mainly marked by difficulties with focus and organisation, the hyperactive-impulsive type is more noticeable due to outwardly disruptive behaviours. Individuals with this subtype often display excessive physical movement, difficulty sitting still, and challenges with controlling their impulses. 

This form of ADHD is commonly diagnosed in children, as the symptoms are more visible in environments like schools. However, many adults also experience this type, though the symptoms may manifest as internal restlessness or difficulty with self-regulation rather than overt hyperactivity.

Key Symptoms of Hyperactive-Impulsive ADHD 

Here are key symptoms of hyperactive-impulsive ADHD:  

Restlessness and Fidgeting  

Individuals with hyperactive-impulsive ADHD often feel the need to move constantly. This may manifest as fidgeting, tapping feet, or an inability to stay seated during tasks that require focus, such as meetings or lectures. 

Impulsivity  

Impulsivity is another hallmark symptom. People with this subtype may interrupt conversations, act without considering the consequences, or make hasty decisions in personal and professional settings. 

Difficulty Waiting and Impulse Control  

Patience is a challenge for individuals with hyperactive-impulsive ADHD. They may struggle to wait their turn in group settings or experience frustration when things don’t happen immediately. 

Excessive Talking or Interrupting  

Impulsivity often leads to talking excessively, interrupting others, or blurting out thoughts without thinking about how it may affect the situation. 

In conclusion, while hyperactive-impulsive ADHD is most diagnosed in childhood, it can persist into adulthood. If left unmanaged, it can cause challenges in both personal and professional life.
