Assessments for ADHD

Assessments for ADHD

Attention Deficit Hyperactivity Disorder is a complex diagnosis that requires a comprehensive evaluation.  It is characterized by symptoms of inattention, hyperactivity, and impulsivity.  All children demonstrate these behaviours to some degree.  However, individuals with ADHD have symptoms that far exceed others their age and significantly impact their ability to function.  These symptoms can impact school performance, daily living, and social functioning.

Parents may notice signs such as:

  • Lack of focus

  • Interrupting

  • Trouble waiting their turn

  • Daydreaming

  • Forgetfulness

  • Difficulty getting organized

  • Difficulty managing emotions

  • Teacher reporting concerns about a child’s ability to pay attention in class

It is important to keep in mind that not all individuals with ADHD demonstrate these symptoms and symptoms can change based on a child’s developmental period.

There is no single checklist that can reliably diagnose ADHD.  An important part of the diagnosis is gathering information regarding an individual’s developmental history, as well as information from teachers and parents.

ADHD is also associated with other complicating factors.  For example, a high percentage of individuals with ADHD also have learning disorders / learning disabilities.  In addition, many individuals with ADHD demonstrate relative cognitive weaknesses.  For example, they can have difficulties with memory or speed of processing.  ADHD can also coexist or be misdiagnosed due to symptoms of emotional (i.e. anxiety, depression), behavioural (conduct issues), developmental (language or learning disorders), and physical (i.e. lack of sleep, tics) issues.

During the assessment process, it is important to determine whether or not other factors may better account for the challenges an individual is experiencing.  It is highly recommended that a formal cognitive and academic assessment is completed to identify academic performance and underlying learning problems that may be impacting performance.  In addition, evaluating an individual’s executive functioning skills provides further information for programming.

A comprehensive evaluation will provide guidance in terms of recommendations for interventions at home and at school.  In addition, parents will have the peace of mind that a thorough evaluation has taken place.  With identification and intervention, individuals can lead successful lives and reach their potential.
