Application of Digital Twins' Technology in Patients Who Had a Stroke, With Moyamoya Disease and With Cerebral Amyloid Angiopathy (CAA) During the Secondary Prevention Phase: A Proof of Concept Using a Randomized Control Trial (Clinical Study 6, STRATIF-AI Project)

The goal of this clinical trial is to obtain initial feedback on the implementation of the STRATIF-AI platform and digital twin in the secondary prevention phase in patients with stroke, Moyamoya disease and Cerebral amyloid angiopathy, including adults of both sexes. The main questions it aims to answer is: how is the patients' experience regarding the use of the STRATIF-AI platform? Researchers will compare Arm 1, who use the STRATIF-AI app in addition to standard secondary prevention, against Arm 2, who receive standard secondary prevention only, to collect feedback regarding the platform usability. Participants in the Arm 1 will: * Complete cognitive and psychological assessments at the time of the first visit and after six months * Follow the indications received from the clinician for standard secondary prevention * Use the STRATIF-AI app daily for health management * Optionally, purchase wearable devices that connect to the app. * Participate in interviews at the six-month mark to share their experiences with the app. Patients in the Arm 2 will: * Complete cognitive and psychological assessments at the time of the first visit and after six months * Follow the indications received from the clinician for standard secondary prevention
