Attention Deficit Hyperactivity Disorder (ADHD) General Information

What is ADHD?

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder which presents inattentive/disorganized behaviours and/or hyperactive/impulsive behaviours.¹

Types of ADHD

There are 3 types of ADHD:

1. Predominantly inattentive/disorganized – describes people who may have trouble focusing, organizing, finishing tasks (especially those that require extra focus), and sticking to one task. They may also make careless mistakes.¹

• Predominantly hyperactive/impulsive – describes people who may be fidgety, chatty, and may experience difficulty waiting their turn and concentrating. They may also act without thinking and may have a poor sense of danger.¹

• Predominantly combined – describes people who have a mix of both inattentive and hyperactive traits.¹

Other Important Information

• People with ADHD are more likely to have other mental health conditions such as anxiety.¹
• Challenges may include academic struggle, poor self-esteem, and engaging in unfavourable behaviours (for example, acting out).²
• Women and girls with ADHD are more likely to go undiagnosed than men and boys because they present more inattentive symptoms, and are less disruptive.³
