Attention Deficit/Hyperactivity Disorder (ADHD)

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurobiological developmental disorders impacting individuals across the lifespan. According to the American Psychiatric Association (APA), it is estimated that 5% of children and anywhere from 2.5 to 4% of adults have ADHD. In order to be diagnosed with ADHD, an onset of symptoms must occur before the age of 12 and be present in at least two settings (e.g. school and at home). Some symptoms of ADHD include difficulty paying attention and staying focused, difficulty controlling behavior, and hyperactivity (over-activity).

There are three subtypes of ADHD: a predominantly inattentive presentation, a predominantly hyperactive/impulsive presentation, and a combined presentation which applies when there are six or more symptoms of inattention and six or more symptoms of hyperactivity-impulsivity.

It is important to note, that these symptoms can present differently between males and females and even between children and adults. These differences will be discussed in more detail in the following sections. How to manage symptoms of ADHD and the ways in which it can impact daily life (e.g. home, school, work, and interpersonal relationships) will also be discussed.
