ADHD in children: diagnosis in private practice

The teacher mentions that your child has difficulty sitting still, following instructions, and finishing their work. At home, homework turns into a two-hour marathon. Frustration outbursts are frequent. You've been looking for explanations for several months, maybe even several years. Getting an ADHD evaluation within the public healthcare system in Quebec can take many months depending on the region. This is where private medical clinics play a concrete role.

Approximately 5 to 8 % of school-aged children have ADHD, making it the most common neurodevelopmental disorder (CADDAC, 2023). Most of them can be effectively supported with a timely diagnosis and appropriate management.

Signs that warrant evaluation

ADHD manifestations in children vary based on the dominant subtype. The inattentive profile is characterized by difficulties maintaining attention on tasks, frequent forgetfulness, a tendency to lose personal belongings, poor organization, and high distractibility. The child may appear dreamy, slow to start their work, as if they aren't listening despite normal hearing.

The hyperactive-impulsive presentation is characterized by persistent motor restlessness, difficulty remaining seated, a tendency to run or climb in inappropriate situations, impulsivity in responses, frequent interruption of conversations, and difficulty waiting one's turn. The combined presentation, which is the most common, shows manifestations of both dimensions.

These behaviors must be present in multiple contexts, home and school, and for at least six months to meet the diagnostic criteria. A child who is only restless at home or only at school warrants an evaluation, but the picture is more complex to interpret.

The medical evaluation process

ADHD assessment in children is clinical. It is based on gathering information from parents and teachers, using standardized questionnaires such as the Conners or SNAP-IV, and a medical examination to rule out other causes for the observed difficulties, particularly vision or hearing problems, sleep disorders, anxiety, or learning disabilities.

The physician or NP who conducts the assessment also collects developmental history, school results, family history of ADHD, and possible comorbidities. A neuropsychological assessment performed by a neuropsychologist can complement the medical evaluation, particularly when the clinical picture is complex or learning disabilities coexist.

Support options

ADHD management in children is multimodal. Behavioral interventions, including child-adapted cognitive-behavioral therapy and parent training programs, form the cornerstone of management, particularly in preschool and school-aged children. School accommodations, such as extra time for exams or a less stimulating work environment, can make a significant difference without requiring medication.

Stimulant medication, primarily methylphenidate in Quebec, is effective in reducing ADHD symptoms in about 70-80 % of children and improves academic performance and social interactions in many cases. The decision to medicate is made jointly by the doctor, parents, and, as much as possible, the child, after evaluating the expected benefits and possible side effects.

Frequently Asked Questions about ADHD in Children

Can a child have ADHD and be intellectually gifted?
Yes. Giftedness and ADHD can coexist, which is called twice-exceptionality. Twice-exceptional children can compensate for their attention difficulties with their intelligence, which often delays diagnosis. Their difficulties only clearly manifest when academic demands exceed their capacity to compensate.

Is ADHD caused by too much screen time?
No. Current data indicate that ADHD is a neurodevelopmental disorder with a strong genetic basis. Excessive screen time can worsen some attention-related symptoms, but it is not the cause of them.

Does ADHD disappear in adolescence?
Not necessarily. For many children, symptoms persist into adolescence and adulthood, even if their expression changes. Motor hyperactivity tends to decrease, while inattention and impulsivity can persist.

When to consult a healthcare professional

If your child has persistent attention, behavioral, or academic difficulties that match the signs described, if the school has expressed concerns, or if you wish to obtain an evaluation without waiting for public network delays, a medical consultation is necessary.

A doctor or a specialized nurse practitioner can conduct an initial assessment, use standardized questionnaires, and refer you to appropriate diagnostic and therapeutic resources. An in-person consultation at one of the service points Omicron Clinic in Quebec gives you quick access.
