1. A method of using a personal mobile device to monitor a patient having a predetermined mental and/or behavioral disorder comprising the steps of: logging historic measured input from at least one of a plurality of sensors provided by the personal mobile device, wherein the measured input represents values attributed to at least one physical behavior of the patient, and wherein the DSM defines the at least one physical behavior as representative of a symptom of the predetermined mental/behavior health disorder; establishing a baseline of measured input from the logged historic measured input when the historic measured input is associated with normal behavior of the patient as defined by a supporting environment of the patient; establishing a threshold of measured input based in part on the baseline of measured input and a deviation in values attributed to the at least one physical behavior, wherein the DSM defines the deviation in values as indicative of an abnormal mental state of the patient for the predetermined mental and/or behavioral disorder; and comparing a current measured input from the at least one of the plurality of sensors so as to determine if the current measured input exceeds the threshold of measured input, so as to monitor the patient.
