6. If taking an approved cholinesterase inhibitor or NMDA antagonist for treatment of Alzheimer’s disease, treated with a stable dose for at least 6 months prior to the screening visit and the dose is not expected to change during the study as per investigators judgement, or must be off such Alzheimer medication for a period of 8 weeks prior to screening

Diagnóstico de EA y excluyendo otras posibles causas de demencia. Si ha habido un cambio significativo en el estado clínico indicativo de un accidente cerebrovascular u otra posible enfermedad neurológica central con inicio entre el momento de la última resonancia magnética o tomografía computarizada y la evaluación durante la selección, la exploración debe repetirse durante los procedimientos de selección si el investigador lo considera apropiado. 3. Edad 50 a 85. 4. IMC por encima de 18 y por debajo de 35 kg/m2 (preferiblemente por debajo de 30 kg/m2). 5. Si toma medicamentos concomitantes, y el tratamiento es con dosis estables de medicamentos esencialmente necesarios para condiciones médicas crónicas que no conducen a la exclusión, durante un período de al menos 3 meses antes de la selección, y se espera que el régimen de dosis permanezca estable durante la realización del estudio. 6. Si está tomando un inhibidor de la colinesterasa aprobado o un antagonista de NMDA para el tratamiento de la enfermedad de Alzheimer, tratado con una dosis estable durante al menos 6 meses antes de la visita de selección y no se espera que la dosis cambie durante el estudio según el criterio de los investigadores, o que no esté bajo ese tratamiento para el Alzheimer durante un período de 8 semanas antes de la selección. 7. Dispuesto y capaz de dar su consentimiento informado. 8. Contar con un cuidador que asista al participante todos los días y que tenga un conocimiento íntimo del estado cognitivo, funcional y emocional del participante y del cuidado personal del participante. El cuidador debe estar dispuesto a acompañar al participante a todas las visitas del estudio y supervisar la administración del fármaco del estudio e informar de las reacciones adversas. El cuidador debe estar dispuesto y ser capaz de dar su consentimiento informado para su propia participación, y saber leer y escribir. 9. Ser capaz de leer, escribir y hablar claramente para las pruebas cognitivas, con capacidad visual y auditiva suficientes para permitir la realización de las pruebas cognitivas. |
