Essentially this paper focuses on the events where diabetes patients might have initialized a stroke event, so that the necessity to make the best decision is critic in order to guarantee a fast recover in the short term.

When all these variables are fully interconnected among them the full response might very encouraging in those cases where critic and non-critic patients might to anticipate unexpected events against their wellness in the shortest times in comparison with current systems.
