Abstract:
1. A method of analyzing a subject for sleep disorders over a test time period comprising the steps of: a) determining that a subject has maintained a normal sleeping pattern prior to the analysis; b) using at least one sensor to measure the subject's brain wave signals over a measurement time period, the measurement time period comprising a number of time segments; c) analyzing the subject's brain wave signals to estimate or determine a number or a power spectrum profile for each time segment; and d) making a determination that the subject has a sleep disorder based in part on a computed number based on the number for each time segment over the measurement time period exceeding a predetermined threshold number, a profile of the numbers over the measurement time period exceeding a predetermined threshold profile over the time period, or the power spectrum profile exceeding a predetermined threshold power spectrum profile over the measurement time period.
