Attention Deficit Hyperactivity Disorder (ADHD)

Attention Deficit Hyperactivity Disorder (ADHD) is a childhood-onset neurodevelopmental disorder that interferes with functioning through a persistent pattern of inattention and/or hyperactivity-impulsivity.


What are the signs and symptoms?

Though most cases are diagnosed during childhood (children between 6 – 12 years old), it can also affect adults. Those with ADHD may experience high activity levels, difficulty remaining still for long periods of time, and limited attention spans.

ADHD is diagnosed as one of three types: Inattentive type, Hyperactive/Impulsive type or combined. 


Signs

Inattentive Type:

  • Has problems staying focused on tasks or activities, such as lectures, conversations, or long reading. (e.g. Short attention span and easily distracted)
  • Does not seem to listen when spoken to (mind seems to be elsewhere)
  • Does not pay close attention to details or makes careless mistakes in school or with job tasks
  • Has problems organizing and prioritizing tasks and work (e.g. misses deadlines, does not manage time well)
  • Avoids or dislikes tasks that require sustained mental effort, such as preparing reports and completing forms
  • Appears forgetful or loses things. (e.g. with doing chores and/or running errands. Older teens and adults may forget to pay bills, return phone calls)

Hyperactive/ Impulsive type:

  • Restlessness: for example - cannot sit still, constantly fidgeting, tapping hands or feet, running around)
  • Difficulty concentrating
  • Excessive talking
  • Lack of self-control or self-regulation: for example - cannot wait their turn, blurts out answers before a question has finished
  • Breaking boundaries: for example - cutting into conversations, games or activities or using other people’s things without permission.
  • Little or no sense of danger
