Getting your child an ADHD diagnosis can be an overwhelming process. At Lavendla, we want to give you a clear and thorough insight into the process to make the difficult easier.

What is ADHD?

Attention deficit hyperactivity disorder (ADHD) is a neuropsychological disorder that affects concentration, organization and planning. The most common characteristics of ADHD are difficulty concentrating, impulsivity and hyperactivity. Children with ADHD may also have difficulty managing their emotions and have poor self-esteem and self-image.

It is not entirely clear what causes ADHD, but there are certain factors that seem to contribute to the diagnosis. These factors include genetics, central nervous system differences, and the environment. There may also be biological causes such changes in dopamine and norepinephrine production.

Each child’s experience with ADHD is unique, making a thorough assessment essential.

What set our therapist apart was her genuine empathy and personal insight. Not only did she possess a deep understanding of neurodiversity, but she also shared personal experiences that resonated with us, creating an instant connection and fostering a sense of trust!

First step: Identifying symptoms

It is important to know what to look out for if you suspect your child may have ADHD. Symptoms may include:

  • Difficulty maintaining attention
  • Hyperactive behaviour
  • Impulsive actions
  • Difficulty organizing and completing tasks

If you notice these symptoms and see that they affect your child’s daily life, it may be time to consider an assessment.

Private child ADHD assessments

An ADHD assessment at a private clinic follows the same procedure as if you were to go through the public healthcare system:

  • First contact: You will be put in touch with a licensed psychologist who has experience conducting ADHD assessments for children.
  • Initial meeting: We hold an initial assessment meeting to discuss your child’s symptoms and needs. This may include a discussion of the family’s medical history but also information about problems at school.
  • Investigation phase:
    • You will see a doctor who specializes in psychiatry for an assessment.
    • We perform standardized tests to evaluate attention, impulse control and other cognitive functions.
    • We conduct diagnostic interviews with the child but also with parents and teachers to get a better picture.
  • Evaluation and diagnosis: After all the data has been collected, the doctor and psychologist make a joint assessment and possibly a diagnosis.
  • Treatment plan: If a diagnosis of ADHD is made, an individual treatment plan is created. Interventions may include medication, cognitive behavioural therapy adapted for ADHD, and caregiver training for family members.
  • Follow-up and support: Regular follow-ups to review and adjust the treatment plan may occur as needed.

When can an ADHD assessment happen?

Each child is unique, so it is important to tailor the assessment process to the specific needs of each child. Symptoms of ADHD can have many causes and before starting an assessment it is important to rule out that the symptoms are not due to other factors in the child’s life. These may include stress, parenting difficulties or bullying. Schools also have a duty to put measures in place to support students, so connecting with them to explore options and accommodations to see if that helps is also a good first step. Additionally, children should ideally be between 4-12 for their initial assessment. This is because behaviour can change rapidly in very young children, and in adolescence changes in development can make it difficult to distinguish from symptoms of ADHD . An ADHD assessment takes about 20 hours and usually takes place over 2-3 months.

What happens after an assessment?

After the assessment, the next step is to discuss interventions and treatment plans. Treatment can include medication, psychological treatment with cognitive behavioural therapy or a combination of both. Next, the school is involved, so that they can be made aware of the treatment plan and start implementing accommodations. It is also important that parents receive support with understanding ADHD and learning how to best support their child.

Parenting a child in need of additional support can be a difficult journey. But remember, it’s never too late to seek help and get the care you and your child need. The first step is to talk to a healthcare provider who can guide you through assessment and diagnosis.

Why is an assessment important?

An assessment can give you answers and an understanding of your child’s potential difficulties, which in turn can lead to better support and help. It can also be a relief to have an explanation for certain behaviours or challenges. There are also hereditary factors in ADHD, so it is not uncommon for parents to identify symptoms in themselves as well.

Seeking help for your child is a big step and we are here to support you through the process. Remember that an assessment can be the start of a journey towards understanding and support, which can make a significant difference in your child’s life.


12 common questions and answers about ADHD assessments

What is an ADHD assessment for children?

An ADHD assessment is a process in which psychologists and doctors carry out various tests and interviews to determine whether a person has an attention problem with impulsivity and hyperactivity.

How does an ADHD assessment work?

The assessment typically includes cognitive tests, diagnostic interviews and a thorough medical and psychological history to understand the child’s history and current situation, involving both parents and the school.

How long does an assessment for ADHD for children take?

The duration of an ADHD assessment can vary, but it usually takes at least 20 hours and is usually completed in about 2-3 months.

What are the symptoms to look out for that could indicate ADHD?

Symptoms that may warrant an assessment for ADHD in children include difficulty listening, being easily distracted, forgetting and losing things, restlessness and impulsivity.

At what age can an ADHD assessment be carried out?

Children should ideally be between 4-12 for their initial assessment. This is because behaviour can change rapidly in very young children, and in adolescence changes in development can make it difficult to distinguish from symptoms of ADHD. It can be helpful to have tried preventive measures before starting an assessment. It is also possible to have unnoticed symptoms that only become apparent or problematic in adulthood as demands and responsibilities increase, which can lead to a late diagnosis.

My child often fights, do they have ADHD?

Children can be disruptive, however this does not mean that it is due to ADHD. It could be difficulties in expressing their feelings and getting their needs met. Adolescence is also a time of great change. That’s why it’s important to have a thorough assessment before an investigation to get the right support.

Do I need a referral for an ADHD assessment?

In public health care, a referral from a health care center is needed. Private clinics accept patients without a referral and often have shorter waiting times.

What interventions are available if my child is diagnosed with ADHD?

Treatment can include extra support measures at school, but also medication, cognitive behavioural therapy adapted to ADHD, and support strategies to cope with everyday life. It is also important for parents and caregivers to receive education about the condition.

What can I do to prepare myself and my child for an ADHD assessment?

It is important to talk to your child about the assessment and to have a dialogue with the school so that you can get an overall picture of your child’s concerns. If there are previous assessments, it is a good idea to bring documentation for these to the investigator.

Can ADHD be cured?

ADHD cannot be cured, but one third of all those diagnosed as children do not have symptoms of ADHD as adults. This suggests that symptoms can change over time as the brain matures, so it is important that a thorough assessment is carried out so that the child gets the right help.

What is the difference between ADD and ADHD?

ADD used to be its own diagnosis, but is now ADHD with inattentive and distractable subtype.

My child has other problems like sleep problems and anxiety, can I get help with this?

Usually during an ADHD assessment, a thorough assessment is conducted to rule out and treat other psychological problems that may be related to ADHD.

Steps in ADHD treatment for children

Seeking help and treatment for ADHD is an important process that can significantly improve quality of life. If you suspect that your child is suffering from ADHD-related symptoms, you can follow these steps:

1. Recognize symptoms

Note when and how your children experience symptoms and how it affects your daily life. This may include forgetfulness, difficulty organizing tasks, or intense activity levels.

2. Consult a licensed healthcare provider

Make an appointment with a licensed psychologist for an initial assessment. Here you can find out if it would be helpful to proceed with an assessment.

3. Evaluation and diagnosis

A doctor and psychologist will work together in the assessment, conducting interviews and cognitive tests to determine whether your child’s symptoms are consistent with ADHD. Involving your child’s school in this process is important.

4. Treatment plan

After diagnosis, we develop a treatment plan. This includes feedback to the school and interventions that may include medication, therapy and support for parents.

5. Medication

Stimulant and non-stimulant medications may be prescribed to help control symptoms. The effects and side effects of the drugs will be closely monitored.

6. Therapy and support

Cognitive behavioural therapy (CBT) adapted for ADHD may be recommended to help manage symptoms. Caregiver education and parental support are also important.

7. Adaptations at school

The school plays an important role in a child’s assessment. Sometimes it is the school itself that initiates an investigation. Regardless, it is important to involve the school in the assessment and support process to ensure that the child receives the right interventions during their time at school.

8. Follow-up and adjustment

Regular follow-up meetings with the treating doctor and psychologist to adjust the treatment plan may occur. This is also the time to address any side effects or questions.

What can I do for my child in everyday life?

Lifestyle is important for children with ADHD and routines such as regular exercise, a healthy diet and adequate sleep are essential. It is also important to teach your child how to manage their emotions, set healthy boundaries and build on their strengths. ADHD can lead to problems with self-esteem and self-image, so it is important to see your child for who they are and accept them despite their difficulties.

As starting treatment can often seem challenging, the best step in the right direction can be just having a conversation with a psychologist or therapist. This is why we offer introductory sessions with our therapists where you can connect over video for 20 or 45 minutes. Do not hesitate to reach out for support. Together, we can make the difficult easier.
