The present disclosure relates to systems and methods for accessing a data structure including a subject identifier identifying a subject and a subject connectivity value derived from at least one of a scan or test provided to the subject, the subject connectivity value representing a magnitude of a connection associated with at least one sub-processing region of a nervous system of the subject; comparing the subject connectivity value to a connectivity threshold value to determine a classification of the subject; determining that the subject connectivity value exceeds the connectivity threshold value, storing in the data structure, an association between the subject identifier and a first classification value corresponding to a first classification or determining that the subject connectivity value is less than the connectivity threshold value, and storing in the data structure, an association between the subject identifier and a second classification value corresponding to a second classification.
