A study measuring the effect and safety of 10 or 20 mg/day of the study drug Lu AA21004 and placebo in the treatment of cognitive dysfunction (such as problems with the ability to think, learn and remember, plan, solve problems and concentrate) in adult patients with Major Depressive Disorder. Patients will be assigned to treatment based on computer-aided random draw and no one involved in the study will know what treatment is given until the whole study is finished
