1. An apparatus comprising:
a first temperature sensor positioned to measure a first temperature of a left Abreu Brain Thermal Tunnel (ABTT) terminus located between a left eyebrow and a left eye of a subject and to transmit a first signal representing the first temperature;
a second temperature sensor positioned to measure a second temperature of a right ABTT terminus located between a right eyebrow and a right eye of the subject and to transmit a second signal representing the second temperature;
a processor configured to receive the first signal and the second signal, the processor then configured:
to identify a temperature decrease of greater than or equal to 0.2 degrees Celsius at the left ABTT terminus and the right ABTT terminus after compensation of the temperature decrease of greater than or equal to 0.2 degrees Celsius for an ambient temperature, and to transmit a first alert signal when the temperature decrease of greater than or equal to 0.2 degrees Celsius is identified during a time interval of less than 120 minutes that occurs at a time that takes place before a sleep time;
to identify a temperature decrease of greater than or equal to 0.4 degrees Celsius at the left ABTT terminus and the right ABTT terminus after compensation of the temperature decrease of greater than or equal to 0.4 degrees Celsius for ambient temperature during a time interval of less than 96 hours, and to transmit a second alert signal when the temperature decrease of greater than or equal to 0.4 degrees Celsius is identified; or
to identify a temperature decrease of greater than or equal to 0.5 degrees Celsius at the left ABTT terminus and the right ABTT terminus after compensation of the temperature decrease of greater than or equal to 0.5 degrees Celsius for ambient temperature during any time interval, and to transmit a third alert signal when the the temperature decrease of greater than or equal to 0.5 degrees Celsius is identified; and
an alert device configured to receive the transmitted first, second or third alert signals and to provide an alert,
wherein the alert provided when the first alert signal is received by the alert device is for at least one selected from the group consisting of a seizure, a stroke, a heart attack, and heart disease.
