System And Method For Treating And Preventing Cognitive Disorders
A computer system is configured to present an individual having Alzheimer's disease or other form of dementia by stimulating the individual's brain using one or both of sensory stimulation and an electrical current. The individual's brain may be stimulated while the individual is awake, or asleep. In situations where the individual is asleep, the computer system may also determine the individual's sleep-stage. Stimulating the individual's brain induces gamma frequency activity in the individual's brain. The gamma frequency activity is captured and used to provide real-time feedback in a loop to the user regarding their brain's oscillatory activity to enhance the entrainment of the gamma frequency by the sensory stimulation and/or the electrical current.

USPTO Full Text Publication >
- 1. A method for treating an individual with a cognitive disorder, the method comprising:
stimulating an individual's brain using one or both of sensory stimulation and an electrical current; and
while the individual's brain is being stimulated:
receiving signals indicating gamma frequency oscillatory activity in the individual's brain induced by the stimulation;
generating feedback information based on the signals indicating the gamma frequency oscillatory activity in the individual's brain;
outputting the feedback information in a feedback loop; and
enhancing entrainment of gamma frequency induced by the stimulation in the individual's brain responsive to the feedback information in the feedback loop.
- 14. A computing device for treating an individual with a cognitive disorder, the computing device comprising:
communications interface circuitry configured to with an Electroencephalography (EEG) device attached to an individual being treated for a cognitive disorder; and processing circuitry operatively coupled to the communications interface circuitry, and configured to:
stimulate an individual's brain using one or both of sensory stimulation and an electrical current; and
while the individual's brain is being stimulated:
receive EEG signals indicating gamma frequency oscillatory activity in the individual's brain induced by the stimulation;
generate feedback information based on the EEG signals indicating the gamma frequency oscillatory activity in the individual's brain;
output the feedback information in a feedback loop; and
enhance entrainment of gamma frequency induced by the stimulation in the individual's brain responsive to the feedback information in the feedback loop.
- 24. A non-transitory computer-readable medium having a control application program stored thereon that, when executed by processing circuitry of a computing device, causes the computing device to:
stimulate an individual's brain using one or both of sensory stimulation and an electrical current; and while the individual's brain is being stimulated:
receive EEG signals indicating gamma frequency oscillatory activity in the individual's brain induced by the stimulation;
generate feedback information based on the EEG signals indicating the gamma frequency oscillatory activity in the individual's brain;
output the feedback information in a feedback loop; and
enhance entrainment of gamma frequency induced by the stimulation in the individual's brain responsive to the feedback information in the feedback loop.
