The KORDIAL study is a randomized, controlled, parallel-group trial evaluating the efficacy of a cognitive behavioral therapy for patients at the early stage of Alzheimer's disease. The 3-month experimental intervention consists of 12 individual sessions with regular involvement of carers or other patient proxies. Strategies for improving the patient's coping ability and for enhancing their psychological well-being are combined. The primary outcome criterion is functioning in the everyday context after completion of the intervention and after another 6 months. The control condition will be treatment as usual. The study will be conducted in 5 university outpatient units and in 5 specialist offices.
