The early diagnosis of Alzheimer's disease is essential to enable patients to have access to the available treatments. However, there is a delay between the diagnosis and the onset of symptoms, which can range from 1 year to more than 5 years. In clinical practice, the hippocampal volume, measured by the Scheltens index, is currently used as a marker of the progression of the disease. The purpose of this study is to determine whether the patient's sex, age and ethnicity can influence the delay in the expression of cognitive troubles reported by the family at the first medical consultation, as well as to determine if there is a correlation between the delay reported by the family and the Scheltens index.
