ADHD
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common mental disorders affecting children. Symptoms of ADHD include inattention (not being able to keep focus), hyperactivity (excess movement that is not fitting to the setting) and impulsivity (hasty acts that occur in the moment without thought). ADHD is considered a chronic and debilitating disorder and is known to impact the individual in many aspects of their life including academic and professional achievements, interpersonal relationships, and daily functioning (Harpin, 2005). ADHD can lead to poor self-esteem and social function in children when not appropriately treated (Harpin et al., 2016). Adults with ADHD may experience poor self-worth, sensitivity towards criticism, and increased self-criticism possibly stemming from higher levels of criticism throughout life (Beaton, et al., 2022). Of note, ADHD presentation and assessment in adults differs; this page focuses on children.
An estimated 8.4% of children and 2.5% of adults have ADHD (Danielson, 2018; Simon, et al., 2009). ADHD is often first identified in school-aged children when it leads to disruption in the classroom or problems with schoolwork. It is more commonly diagnosed among boys than girls given differences in how the symptoms present. However, this does not mean that boys are more likely to have ADHD. Boys tend to present with hyperactivity and other externalizing symptoms whereas girls tend to have inactivity.
There are three main types of ADHD:
- Predominantly inattentive presentation.
- Predominantly hyperactive/impulsive presentation.
- Combined presentation.
A diagnosis is based on the presence of persistent symptoms that have occurred over a period of time and are noticeable over the past six months. While ADHD can be diagnosed at any age, this disorder begins in childhood. When considering the diagnosis, the symptoms must be present before the individual is 12 years old and must have caused difficulties in more than one setting. For instance, the symptoms can not only occur at home.
