[On disclosing a diagnosis of dementia].

Disclosing a diagnosis of dementia to the patient has become a scientific topic only in the last decade. This review gives an up-to-date account of ongoing research. After an introductory discussion of the pros and cons, the unsatisfactory situation of disclosure in the European Union is analysed. Afterwards, the wish of being told a diagnosis of dementia among healthy old people, people with dementia and their relatives is described. The first empirical studies about coping with the diagnosis are presented. Suggestions of new directions in coping research are made. Finally, recommendations for communicating the diagnosis to the patient and the family are given.
