What is ADHD?

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that affects concentration, impulse control, and sometimes hyperactivity. It manifests differently in each individual and can have a significant impact on their daily lives.

The different types of ADHD

There are three main types of ADHD:

  • ADHD with predominantly inattentiveness : Affected individuals primarily have difficulty concentrating, staying organized, and completing tasks.

  • Predominant hyperactivity and impulsivity : This type of ADHD is characterized by constant restlessness, frequent interruptions, and decisions made without thinking.

  • Combined form : This form combines the symptoms of the first two types, with inattention, hyperactivity and impulsiveness.

ADHD in adults and children

The manifestations of ADHD often differ between children and adults.

In children, this disorder manifests as difficulty concentrating in class, marked impulsiveness and an almost constant need to be on the move, which can lead to problems at school or in social interactions.

In adults, however, symptoms often take different forms, including time management problems, frequent forgetfulness, high impulsiveness in personal or professional relationships, and a feeling of frustration that can sometimes build up and cause stress.

These differences highlight the importance of a diagnosis adapted to each stage of life.

How is ADHD diagnosed?

Diagnostic process

Identifying ADHD requires a thorough assessment conducted by a specialized healthcare professional, such as a psychiatrist, psychologist, or pediatrician. This assessment process combines several essential steps to ensure an accurate diagnosis.

First, standardized questionnaires are typically used to examine the presence and intensity of key symptoms, such as inattention, hyperactivity, and impulsivity.

Then, an observation of behaviors in different contexts at home, at school or at work allows us to assess the functional impact of ADHD on daily life.

Finally, collecting medical, family and school history plays a crucial role in identifying hereditary factors or other elements that may influence the development of symptoms.

This approach ensures tailored and individualized care for each person concerned.

Role of health professionals

Healthcare professionals provide tailored advice, taking into account the specific needs of each individual.

This may include the implementation of personalized educational strategies, adjustments in school or work settings, or even therapeutic recommendations, such as behavioral or medical therapy.

They work collaboratively with families, teachers, and other stakeholders to create a supportive environment where the person with ADHD can thrive.
