About ADHD Clinic
ADHD Klinik Copenhagen is part of Alethia, a clinic with psychiatrist and psychologist under one roof.
Our mission
Fast and thorough ADHD assessment
The public sector wait time for ADHD assessment is 1.5-3 years. This means many adults live with untreated ADHD for years, affecting their work, relationships, and quality of life.
We offer assessment with short wait times, where you are thoroughly evaluated by licensed psychologists and psychiatrists. No referral needed.
70-80% of everyone with ADHD has at least one comorbid condition. That is why we always start with a comprehensive screening, so we can provide the right treatment, not just for ADHD, but for the full picture.
Our approach
Evidence-based assessment
We use DIVA-5 as the primary diagnostic tool for ADHD assessment, recommended by the Danish Health Authority. DIVA-5 covers all DSM-5 criteria for ADHD, both in childhood and adulthood.
70 to 80 percent of everyone with ADHD has at least one comorbid condition. That is why we always start with a comprehensive clinical screening covering anxiety, depression, trauma, personality disorders, and other diagnoses that can resemble or overlap with ADHD.
Psychologists conduct interviews and assessment and reach the diagnostic conclusion. Psychiatrists review the full picture and manage medical treatment. The collaboration between disciplines ensures no part of your care is overlooked.
