Abstract

Automated behavioral methods and systems for treating Insomnia that use passive means for determining wake/sleep states.

Claims

1. An automated system for facilitating the implementation of Behavioral Therapy that exploits information indicative of a user'"'"'s wake/sleep state to improve the user'"'"'s sleep or sleep hygiene, comprising:

means for passively determining information indicative of the user'"'"'s wake/sleep state; and

means for implementing the steps of the Behavioral Therapy utilizing the user'"'"'s wake/sleep state information.

2. The system of claim 1 in which the Behavioral Therapy comprises at least Stimulus Control Therapy, Sleep Restriction Therapy, Relaxation Therapy, Cognitive Behavioral Therapy for Insomnia, Behavioral Therapy for Insomnia, and combinations of two or more of Stimulus Control Therapy, Sleep Restriction Therapy, Relaxation Therapy, Cognitive Behavioral Therapy for Insomnia, and Behavioral Therapy for Insomnia.

3. The system of claim 1 including means for choosing the Behavioral Therapy to be implemented for a user based on the user'"'"'s personal wake/sleep information.

4. The system of claim 1 in which information indicative of user'"'"'s sleep/wake state is taken from the group consisting of:

EEG, EMG, PAT, systolic upstroke time, ECG/EKG, EOG, oximetry, heart rate variations, heart rhythm variations, actigraphy, body movement, GSR, respiratory changes, respiratory variability, eye movements, and combinations of two or more of these means for passively determining information indicative of the user'"'"'s wake/sleep state.

5. The system of claim 1 in which drug Therapy is used in conjunction with the Behavioral Therapy.

6. The system of claim 1 in which active means for determining the wake/sleep state are used to supplement the means for passively determining information indicative of the user'"'"'s wake/sleep state.

7. The system of claim 1 in which the Behavioral Therapy is Stimulus Control Therapy including means for implementing the Stimulus Control Therapy using the following rules:

a) never alert a user while they are asleep,

b) alert a user only when at least a first predetermined number of contiguous of wake epochs are achieved, and

c) if any sleep of at least the second predetermined number of contiguous epochs is achieved, designate the user in maintenance mode and if any sleep of at least the second predetermined number of contiguous epochs is not achieved, designate the user not in maintenance mode whereby

if the user is in maintenance mode, examine a past third predetermined number of epochs and if the user was awake for at least a fourth predetermined number of epochs out of the past third predetermined number of epochs, alert the user, but

if the user is not in maintenance mode and if there is no sleep of at least a fifth predetermined number of contiguous epochs within a first period of trying to fall asleep, then alert the user upon a lapse of the first period; and

if the user is not in maintenance mode and there is a contiguous sleep period contained within the first period of trying to fall asleep that is greater than or equal to the fifth predetermined number of epochs but less than the second predetermined number of epochs, then inhibit the alert for an additional period.

8. The method of claim 7 in which an epoch is about 30 seconds, the first predetermined number of contiguous wake epochs is 2, and the second predetermined number of contiguous epochs is 20 epochs, the third predetermined number of contiguous epochs is 30 epochs, the fourth predetermined number of epochs is 28 epochs;

the fifth predetermined number of contiguous epochs is 10 epochs;

the first period is 40 epochs, and the additional period is 20 epochs.

9. The system of claim 1 in which the Behavioral Therapy parameters are optimized for each user based upon the user'"'"'s wake/sleep information.

10. An apparatus for facilitating the implementation of Behavioral Therapy for a user seeking to improve the user'"'"'s sleep or sleep hygiene comprising:

means for processing information which is indicative of the user'"'"'s wake/sleep state;

means for implementing the Behavioral Therapy utilizing the wake/sleep state information.

11. The system of claim 10 in which means for processing information which is indicative of the user'"'"'s wake/sleep state is taken from the group consisting of:

EEG, EMG, PAT, systolic upstroke time, ECG/EKG, EOG, oximetry, heart rate variations, heart rhythm variations, actigraphy, body movement, GSR, respiratory changes, respiratory variability, eye movements, and combinations of two or more of these means for passively determining information indicative of the user'"'"'s wake/sleep state.

12. The apparatus of claim 10 in which the Behavioral Therapy is Stimulus Control Therapy comprising:

means for determining whether the user should get out of the bed in accordance with the rules of the Stimulus Control Therapy; and

means for alerting the user to leave the bed in accordance with the rules of the Stimulus Control Therapy if a determination is made.

13. The apparatus of claim 10 in which the Behavioral Therapy is Sleep Restriction Therapy comprising:

means for calculating the program parameters including a sleep period for the upcoming sleep session based on previously acquired wake/sleep state information in accordance with the rules of the Sleep Restriction Therapy;

means for determining whether the user has completed the sleep period; and

means for displaying the calculated program parameters to the user for the upcoming sleep session.

14. The apparatus of claim 10 in which the Behavioral Therapy is chosen from the group consisting of Stimulus Control Therapy, Sleep Restriction Therapy, Relaxation Therapy, Cognitive Behavioral Therapy for Insomnia, Behavioral Therapy for Insomnia, and combinations of two or more of Stimulus Control Therapy, Sleep Restriction Therapy, Relaxation Therapy, Cognitive Behavioral Therapy for Insomnia, and Behavioral Therapy for Insomnia.

15. The apparatus of claim 10 including means permitting the user to review and adjust system settings chosen from the group consisting of time, age, sleep goals, alert preferences, language, setup parameters, and display preferences.

16. The apparatus of claim 10 in which the Behavioral Therapy is optimized for each user based upon the user'"'"'s wake/sleep state information and/or wake/sleep state history.

17. The apparatus of claim 10 including means permitting the user to review information previously acquired by the apparatus.

18. The apparatus of claim 10 including means for computing the user'"'"'s sleep statistics based on the user'"'"'s previous wake/sleep state history.

19. The apparatus of claim 10 in which an indication of whether the user is in bed or not is acquired along with the wake/sleep state information.

20. The apparatus of claim 10 in which there is a means for turning off any alert and a means to display the user'"'"'s current sleep statistics when a determination is made that the user is no longer in bed.

21. The apparatus of claim 10 in which there is a means for turning off any alert and a means of providing the user with sleep instructions when a determination is made that the user is no longer in bed.

22. The apparatus of claim 12 in which the alerting means are chosen from the group consisting of:

a text display of warning conditions, text display of instructions or information, a display backlight, a blinking light, an audible indication, a tactile indication, a synthesized or recorded voice, a low level electrical stimulus and an aroma generated by appropriate device.

23. The apparatus of claim 10 includes a means to allow the user to specify a predetermined wakeup time.

24. The apparatus of claim 12 including user-controlled means for canceling the alerting means.

25. The apparatus of claim 12 including a visual or audible presentation of instructions or information.

26. The apparatus of claim 12 including a means for providing an indication to the user after the user has been in bed for a recommended length of time.

27. The apparatus of claim 13 including means enabling the user to review and adjust the program parameters after display of such parameters for an upcoming sleep session.

28. The apparatus of claim 10 in the form of a single portable unit wearable by the user.

29. The apparatus of claim 10 including means for calculating a time interval corresponding to the highest likelihood of being able to sleep to assist the user in planning the user'"'"'s sleep.

30. The apparatus of claim 29 including means for informing the user as the user approaches the time interval corresponding to the highest likelihood of sleeping.
