+Medical questionnaires and forms play a crucial role in diagnosing diseases and gathering essential patient information. Traditionally, these assessments are conducted through face-to-face interactions or phone calls, which can be time-consuming, costly, and inefficient. To address these challenges, digital adaptations of medical questionnaires have been developed, enabling faster and more accessible data collection across various platforms and applications.
+
+ResearchKit, an open-source framework introduced by Apple, allows researchers and developers to create robust mobile applications for medical research. By leveraging this technology, large-scale data collection can be conducted efficiently, facilitating real-time analysis while reaching a broader population.

+### Visual Interface
+
+The first part for develop a application is the visual part, you need to create a visual interface because the participants need a intuitive screen. This repository is not about the interface part, only about the ResearchKit part, therefore, we will skip the visual part, we can only say that it is necessary to place 3 buttons, one for consent, another for IPAQ and another for MMSE.

+The visual interface needs to be easy, intuitive, but the design is part of you.
