This study aims to prospectively examine the memory problem perceptions of patients with memory complaints [MCs] and their accompaniers during the diagnostic process.

Through the french adaptation of the "illness perception questionnaire memory", this study aims to prospectively examine the memory problem perceptions of patients with memory complaints [MCs] and their accompaniers during the diagnostic process. The investigators plan to recruit 125 patients with MCs who come for the first time at the Research and Resources Memory Center in Nancy, France. Participants have to express MCs and must be free of dementia diagnosis at the first visit. Participants also need to be accompanied by an accompanier and both have to be fluent in French. This study has been approved by our local Ethics Committee (Committee for the Protection of Persons) and the French Health Security Agency. After giving their informed consent, patients and accompaniers are followed up throughout the diagnostic process with three visits : at their first visit, at one month after the first visit, and at six months after the diagnosis disclosure.
