Secondary characteristics of ADHD

Written By Tanya Keto

There is so much more to ADHD than inattention, hyperactivity and impulsivity.

Over time, people with ADHD may develop secondary characteristics, or patterns and behaviors arising from primary symptoms.

Although they’re often misunderstood and overlooked, secondary traits of ADHD, also known as coexisting conditions or comorbidities, can have a significant effect on emotional wellbeing, relationships, academics, work performance and everyday life.

Secondary characteristics may include:

  • Behaviour disorders, like oppositional defiance disorder (ODD) and/or conduct disorder (CD)

  • Mood disorders, like depression and bipolar disorder

  • Anxiety

  • Tics and Tourette Syndrome

  • Learning disorders

  • Sleep disorders

  • Substance abuse

Learning about secondary characteristics leads to improved support for students, families and educators navigating the ADHD journey.
