General questions
An ADHD assessment costs 9,700 DKK at ADHD Klinik Copenhagen, and with medication initiation a typical course is around 14,800 DKK. This includes clinical interview and screening (2 hours, 3,200 DKK), diagnostic assessment with DIVA-5 (2 hours, 3,500 DKK), feedback where the psychologist compiles the assessment into a written report and treatment plan (1 hour) plus a follow-up feedback session (1 hour, 3,000 DKK total), first psychiatrist consultation with somatic screening (1 hour, 2,700 DKK), and 2 medication adjustments (30 min, 1,200 DKK each). Some people need more medication adjustments, so the total can be higher. You pay per session and are not locked into a package. Payment is made online at booking or by invoice after the session.
Some of our practitioners work with us as independent consultants through their own company, often alongside a position in the public health system, rather than being salaried employees, so we carry less administrative overhead than a traditional clinic. We pass that saving on to you, without cutting the time or quality you get in your assessment.
You do not need a referral to book at ADHD Klinik. You can book directly through our online booking system or email booking@alethia.dk. We are registered with Sygeforsikring Danmark (groups 1, 2, 5, and S). If you are 25 or younger and have a GP referral, you may be eligible for partial reimbursement on assessment. Reimbursement does not cover medication treatment. If you have private health insurance (e.g. through your employer), you pay us directly and apply for reimbursement with the detailed receipt we always provide.
Yes, we offer full assessment and treatment in Danish, English, Norwegian, and Swedish. We prefer the clinical interview (step 1) and first psychiatric consultation to take place in person at our clinic on Fiolstræde 14, but after that, therapy, medication adjustments, and follow-ups can be conducted online. This also applies to clients across Denmark and Danish expats abroad.
ADHD Klinik primarily assesses and treats adults aged 18 and over. Our diagnostic tools (DIVA-5, clinical interview, self-report scales) and our psychiatrists' medication expertise are specifically geared toward adults with ADHD and ADD. In some cases, we can accept clients who are 17 if they turn 18 during the course of the assessment. For children and adolescents under 17, we recommend contacting your GP for a referral to a child and adolescent psychiatric department.
You can book online through our booking system. If you have questions, we prefer that you first send us an email at booking@alethia.dk. We usually reply by email and strive to answer within two business days. If you would rather talk on the phone, include your phone number and a few words about what you would like help with, and we will call you. You can also call us at +45 42 62 00 51 during phone hours (Monday 08:00–10:00 and Thursday 14:00–16:00). You can also ask questions to our AI assistant on the contact page, which can answer the most common questions about assessment, pricing, and wait times. The clinic is located at Fiolstræde 14, 1st floor, 1171 Copenhagen K, in the Latin Quarter near Nørreport Station (approx. 5 min walk).
ADHD assessment
ADD (Attention Deficit Disorder) refers to ADHD without hyperactivity, the predominantly inattentive form. In Denmark ADD is a separate diagnosis. In the international diagnostic systems DSM-5 and ICD-11, ADD falls under ADHD as one of three forms: predominantly inattentive, predominantly hyperactive-impulsive and combined. The inattentive form is often overlooked because it lacks visible hyperactivity. At ADHD Klinik Copenhagen, we assess all three forms using DIVA-5, a semi-structured diagnostic interview. Whether you use the term ADD or ADHD, the assessment process is the same. DSM-5 defines the diagnostic criteria with 18 symptoms across inattention and hyperactivity/impulsivity.
An ADHD assessment at ADHD Klinik follows five steps. Step 1 is a clinical interview and screening (approx. 2 hours, 3,200 DKK), where we conduct a broad psychopathological screening because concentration difficulties can stem from many things beyond ADHD. If the interview points to another condition, we may send a relevant self-report questionnaire for you to complete at home before the next session. Step 2 is diagnostic assessment with DIVA-5, where we recommend bringing a relative (approx. 2 hours, 3,500 DKK). If the screening points to other factors, e.g. autism, we add AAA or an autism anamnestic interview (3,500 DKK). Step 3 is feedback, where the psychologist compiles the assessment into a written report with treatment plan and reviews it with you (3,000 DKK). Step 4 is medication with our psychiatrist including somatic screening (2,700 DKK + follow-ups at 1,200 DKK). Step 5 is therapy and follow-up as needed (1,250 DKK/session). From first contact to stable treatment typically takes 2-3 months.
All new clients start with the clinical interview, including those with an existing diagnosis. This is for several reasons: external diagnoses vary in quality, and research shows that up to 80% of adults with ADHD have at least one other mental health disorder, such as anxiety, depression, or substance use, which can change the treatment plan. Concentration difficulties can also appear in many conditions. The interview ensures we see the full picture so the psychiatrist can create the best possible treatment plan for you. It is not a repetition but a quality assurance that often uncovers factors the previous assessment missed.
Yes, many adults first discover their ADHD in their 30s, 40s, or later. This is especially true for the predominantly inattentive form (ADD), which is often overlooked because symptoms are less visible than hyperactivity. Women are particularly underdiagnosed because ADHD in women more often presents as inner restlessness, emotional dysregulation, and difficulty organizing daily life rather than classic hyperactivity. Many have developed compensatory strategies that mask symptoms. If you recognize persistent problems with concentration, planning, impulsivity, or emotion regulation, an assessment can provide clarity. Our ASRS screening on the website (18 questions, 5 minutes) can be a good starting point.
Yes, concentration difficulties and impulsivity can appear in many conditions: anxiety, depression, bipolar disorder, trauma (PTSD), sleep disorders, and substance use. That is why every course starts with a clinical interview where we screen broadly, so the whole picture is covered. This is crucial for ensuring a correct diagnosis and avoiding incorrect medication. Our model with both psychologists and psychiatrists provides multiple clinical perspectives on the same presentation. If during the assessment we find it is not ADHD, we continue the assessment in the same process with the same psychologist.
For the DIVA-5 interview (step 2), we recommend bringing someone who knew you as a child, such as a parent, sibling, or other close relative. DSM-5 requires that ADHD symptoms were present before age 12, and a relative's perspective significantly strengthens the assessment of childhood symptoms, because many adults with ADHD have difficulty remembering their own childhood precisely. The informant participates in part of the session where the clinician asks questions about your behavior as a child. If it is not possible to bring a relative, we find alternative ways to gather the information, such as school reports, old medical records, or detailed questionnaires.
After the assessment, you receive a written epicrisis with your diagnosis and an individual treatment plan. The epicrisis can be used as documentation for employers, educational institutions, insurance companies, or other healthcare providers. If ADHD is confirmed and medication is relevant, you book an appointment with our psychiatrist. The first consultation includes somatic screening and medication selection. This is followed by follow-up consultations for dose optimization. The psychiatrist retains treatment responsibility for a minimum of 6 months before your GP can take over ongoing prescriptions. Your GP can generally only continue the same dose or reduce it. You can always continue with us beyond the 6 months or return at a later time. We also offer psychotherapy and psychoeducation tailored to your needs.

Diagnostic tools and methods
DIVA-5 (Diagnostic Interview for ADHD in Adults) is the most widely used diagnostic interview for ADHD in adults in Denmark and a semi-structured interview of the type recommended in the Danish clinical guideline for adult ADHD assessment (DMPG, 2025). It systematically reviews all DSM-5 criteria for ADHD, divided into 9 symptoms of inattention and 9 symptoms of hyperactivity/impulsivity, for both current symptoms and childhood symptoms. The interview is semi-structured, meaning the clinician can follow up with clarifying questions based on your answers. We recommend that a relative participates to validate childhood symptoms. DIVA-5 was developed by the DIVA Foundation in the Netherlands and has been translated into over 20 languages.
At ADHD Klinik, psychologists conduct the clinical interview, administer the diagnostic tools (DIVA-5), and make the diagnosis independently. The psychologists are authorized clinical psychologists (the title that from 1 January 2026 corresponds to the former 'autoriseret psykolog') and have experience from both public and private psychiatry. Psychiatrists contribute medical evaluation, somatic and cardiovascular screening, and manage ADHD medication treatment. It is a collaboration between psychiatrist and psychologist, where the psychologist is the primary assessor and the psychiatrist the medical specialist. Both professions are authorized and supervised by the Danish Patient Safety Authority. The advantage of this model is that you get assessment, medication, and therapy all under one roof.
An epicrisis is the written diagnostic report you receive after your assessment at ADHD Klinik. It contains your diagnosis (or conclusion if ADHD is not confirmed), a clinical evaluation of your cognitive functions, results from the diagnostic tests, and an individual treatment plan with recommendations for next steps. The epicrisis is an official health document that can be used to document your diagnosis for other healthcare providers, your GP, employers (e.g. for workplace accommodations), educational institutions (SPS support), insurance companies, or municipal caseworkers. You receive the epicrisis as part of the feedback session (step 3).
ASRS v1.1 (Adult ADHD Self-Report Scale) is a screening tool developed by WHO in collaboration with Harvard Medical School. The test on our website contains all 18 questions: Part A with 6 screening questions that are most predictive of ADHD, and Part B with 12 supplementary questions that provide a broader picture. The test takes about 5 minutes and is completely anonymous. Your answers are not saved or sent to any server; everything is processed locally in your browser. ASRS is a screening tool, not a diagnosis. A high score does not mean you have ADHD, but that it may be worth speaking with a professional. The screening can be a good starting point if you are considering an assessment.
Treatment and therapy
Medication treatment for ADHD is managed by our two psychiatrists and two senior psychiatry residents: Rasmus Wæhrens (specialist in psychiatry, PhD) and Robert Bering (specialist in psychiatry), together with doctors Rafl Adnan and Markus Hjorth. The first psychiatric consultation takes approximately 1 hour (2,700 DKK) and includes somatic and cardiovascular screening, medication selection, and an initiation plan. Methylphenidate is the first-line choice, and approximately 70% respond to it. This is followed by 2 follow-up consultations of 30 minutes (1,200 DKK) over 4-8 weeks for dose optimization and side effect monitoring. You do not need a separate referral to a psychiatrist. Once a stable dose is achieved, typically after at least 6 months of specialist follow-up, your GP can take over ongoing prescription management.
Our psychologists work eclectically, meaning every therapy process is tailored to the individual client. We don't believe in manual-based therapy, but in a meeting between two people, where we draw on the approaches that make sense for you specifically. This may include psychodynamic therapy, cognitive behavioral therapy (CBT), schema therapy, narrative therapy, trauma treatment (CPT), or psychoeducation. Psychoeducation is an important part of ADHD treatment and covers understanding your diagnosis, strategies for planning and structure, emotion regulation, and stress management. For many people, medication and therapy complement each other. Therapy costs 1,250 DKK per session and can take place at the clinic on Fiolstræde 14 or online.
Practical information
In the public system, an ADHD assessment is free, but the adult wait is typically a year and a half or more: psychiatrists' stated waits averaged 80 weeks in 2023 (Danish Health Authority, 2025). At ADHD Klinik, we have short wait times, and an ADHD assessment costs 9,700 DKK, and with medication initiation a typical course is around 14,800 DKK; some people need more follow-ups. We use the DIVA-5 diagnostic interview. The advantages of private assessment are short wait times, flexible booking, and assessment, medication, and therapy all under one roof with psychologist and psychiatrist. You pay per session and are not locked into a full pathway. All new clients start with the clinical interview, regardless of any existing diagnosis.
