Eligibility Criteria

Male or female participants from 18 years up to 55 years old.

Inclusion Criteria: - The patient is aged ≥18 years and ≤55 years. - The patient is willing and able to attend study appointments within the specified time windows. - The patient is an outpatient. - The patient is diagnosed with a primary diagnosis of ADHD according to the DSM-5™ classification. - The patient has an AISRS total score ≥24. - The patient has a CGI-S rating ≥4 (moderately ill or worse). Exclusion Criteria: - The patient has previously been treated with vortioxetine. - The patient has any current psychiatric disorder (DSM-IV-TR™ criteria), other than ADHD, as assessed using the Mini International Neuropsychiatric Interview (MINI). - The patient has a known first-degree relative with bipolar disorder. - The patient suffers from intellectual disability as evaluated by the Wechsler Abbreviated Scale of Intelligence (WASI) II vocabulary and matrix. - The patient suffers from organic mental disorders, or mental disorders due to a general medical condition (DSM-5™ criteria). - The patient has reported current use of, or has tested positive for, drugs of abuse (opiates,methadone, cocaine, amphetamines [including ecstasy], barbiturates, benzodiazepines, and cannabinoids). If a patient tests positive for opiates due to incidental use of codeine containing medication, as assessed in a clinical interview, the drug screen may be repeated up to three weeks later but the retest result must be available from the central laboratory latest at Visit 2 and has to be negative for this patient to be eligible for enrolment. If a patient tests positive for amphetamines due to his/her ADHD current treatment, as confirmed by a clinical interview, the patient is eligible for enrolment provided this treatment is discontinued two weeks prior to the Baseline Visit. - The patient has a history of two prior failed (<50% improvement in symptoms) adequate trials of ADHD treatment. - The patient has any other disorder for which the treatment takes priority over treatment of ADHD or is likely to interfere with study treatment or impair treatment compliance. - The patient has a history of moderate or severe head trauma or other neurological disorders or systemic medical diseases that are, in the investigator's opinion, likely to affect central nervous system functioning. - The patient has attempted suicide within the last 6 months or is at significant risk of suicide (either in the opinion of the Investigator or defined as a "yes" to suicidal ideation questions 4 or 5 or answering "yes" to suicidal behaviour on the Columbia-Suicide Rating Scale (C-SSRS) within the last 12 months).
