- Patients with early signs of dementia of Alzheimer Type - Male and female patients with an age of at least 55 years -MMSE 15-26 - All patients must sign and date an Informed Consent Form personally - Concomitant use of AChEIs is allowed but not required. Patients who are currently taking AChEIs are eligible as long as they have been using a stable dose for at least 3 months prior to screening and no change is foreseen for the duration of the study. This dose must be consistent with the product label in the concerned country. Patients who are not currently taking AChEIs but have taken them in the past are also eligible if AChEIs were stopped at least 3 months prior to screening.

Los pacientes que estén tomando actualmente IACEs son idóneos siempre y cuando hayan estado utilizando una dosis estable durante por lo menos 3 meses antes de la selección y no esté previsto ningún cambio durante el estudio. Esta dosis debe ser coherente con la información del producto en el país en cuestión. Los pacientes que no estén tomando en la actualidad IACEs pero que los hayan tomado en el pasado también son idóneos si los IACEs se suspendieron al menos 3 meses antes de la selección. - Los pacientes deben tener un mínimo de 6 años de nivel educativo formal y fluidez en el idioma de las pruebas, lo que el paciente deberá confirmar verbalmente y documentado por el investigador del estudio. - Los pacientes deben tener un cuidador del estudio fiable (según el criterio del investigador, por ejemplo, un miembro de su familia, pareja, etc., un tutor o, si procede, un representante legal). |
