Abstract
The present invention relates to a method of analyzing a subject for excessive daytime sleepiness, and more particularly to a quick (short duration), quantitative method of sleep disorder analysis. The present invention additionally relates to a method, which can be used to quantitatively measure the treatment endpoints for the subject, i.e., appropriate levels of stimulants. Additionally, the present invention relates to a device for sleep disorder analysis.
Claims20
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.
A method of analyzing a subject for excessive daytime sleepiness over a test time period comprising the steps of;
- a) using at least one sensor to measure a subject's brain wave signals over a measurement time period, the measurement time period comprising a number of time segments;
- b) analyzing the subject's brain wave signals to estimate or determine a power spectrum profile for each of the time segments of the measurement time period, the power spectrum for each time segment comprising an alpha component and at least one sub-alpha component, and from these components a ratio of the one or more sub-alpha components to the alpha components for each time segment;
- and
- c) making a determination of the degree of excessive daytime sleepiness based in part on the ratio of the over the measurement time period.
A method of analyzing a subject for sleep disorders comprising the steps of:
- a) placing electrodes onto a subjects head having a brain wave signal;
- b) providing a stimulus to the subject;
- c) measuring the subject's response to the stimulus and the brain wave signal;
- d) analyzing the brain wave signal;
- and
- e) making a determination that the subject has a sleep disorder based in part on the brain wave signal analysis over a period of time, and in part on the subjects response to the stimulus over the period of time.
