摘要:
A system configured to monitor autoregulation includes a medical sensor configured to be applied to a patient and to generate a regional oxygen saturation signal. The system includes a controller having a processor configured to receive the regional oxygen saturation signal and a blood pressure signal and to determine a cerebral oximetry index (COx) based on the blood pressure signal and the regional oxygen saturation signal. The processor is also configured to apply a data clustering algorithm to cluster COx data points over a range of blood pressures, identify a first cluster of COx data points that corresponds to an intact autoregulation zone for the patient, and provide a first output indicative of the intact autoregulation zone for the patient.

Systems and methods for treating a subject with a psychiatric disorder are provided in which a therapy session is conducted. In the therapy session, each respective expression image in a plurality of expression images is sequentially displayed. Each expression image is independently associated with an expression. The successive display of images is construed as a tiled series of expression image subsets, each consisting of N expression images. Upon completion of the display of each respective subset, the user is challenged as to whether the first and the last images in the respective subset exhibit the same emotion. A score is determined for the respective subset based on whether the subject learned to respond correctly. The number of images in each subset is adjusted to a new number based on these scores. A treatment regimen is prescribed to the subject for the psychiatric disorder based at least in part on the scores.
摘要:
An apparatus and method enables a reading of a continuous beat to beat heart rate at the superficial temporal artery to give an indication of blood pressure of the brain and blood related diseases. The apparatus is non-invasive. Preferably a reading of a continuous beat to beat heart rate is measured on both the left superficial temporal artery and the right superficial temporal artery simultaneously during the same heart beat. Where the wave form measured from the left temporal artery differs from the wave form measured from the right temporal artery this may be an indication of an impending stroke or an indication that a stroke has recently happened. Further, the indices of the wave forms may be used as a clinical indication of other blood related diseases.

The invention concerns a method of analysing the brain activity of a patient performing a given task or in response to an external stimulus, by comparison of standardized data with data in a database, by means of fuzzy logic algorithms.
摘要:
Neural activity in the brain arising from a stimulus is monitored. A stimulus is applied to a target structure of the brain and a neural measurement is obtained from at least one electrode implanted in contact with the target structure. The neural measurement is configured to capture a measure of any late response arising in the target structure, typically being a neural response arising after conclusion of an ECAP, such as in the period 1.5-10 ms after stimulus onset. The late response(s) can be a useful biomarker such as of therapeutic ranges of deep brain stimulation, disease progression, medication efficacy, and intra-operative changes.

The present disclosure provides a device with electrodes configured to record electrical activity that are confined to a restricted area, using recorded biological electrical signals to control cursor position in a speech-assistance interface, and using recorded biological signals to detect arousals during sleep.
摘要:
A method for monitoring an intrabody region of a patient. The method comprises intercepting electromagnetic (EM) radiation from the intrabody region in a plurality of EM radiation sessions during a period of at least 6 hours, calculating a dielectric related change of the intrabody region by analyzing respective the intercepted EM radiation, detecting a physiological pattern according to said dielectric related change. and outputting a notification indicating the physiological pattern.
摘要:
A system for treating a patient comprises a stimulator for stimulating brain tissue, a controller for setting stimulation parameters and a diagnostic tool for measuring patient parameters and producing diagnostic data. The stimulation parameters comprise test stimulation parameters and treatment stimulation parameters. The stimulator delivers test stimulation energy to the brain tissue based on at least one test stimulation parameter and delivers treatment stimulation energy to the brain tissue based on at least one treatment stimulation parameter. One or more treatment stimulator parameters are determined based on the diagnostic data produced by the diagnostic tool The system is constructed and arranged to treat a neurological disease or a neurological disorder. Methods of treating a neurological disease or neurological disorder are also provided.
摘要:
A method for providing electrical stimulation to a user as a user performs a set of tasks during a time window, the method comprising: providing an electrical stimulation treatment, characterized by a stimulation parameter and a set of portions, to a brain region of the user in association with the time window; for each task of the set of tasks: receiving a signal stream characterizing a neurological state of the user; from the signal stream, identifying a neurological signature characterizing the neurological state associated with the task; and modulating the electrical stimulation treatment provided to the brain region of the user based upon the neurological signature, wherein modulating comprises delivering a portion of the set of portions of the electrical stimulation treatment to the brain region of the user, while maintaining an aggregate amount of the stimulation parameter of the treatment provided during the time window below a maximum limit.
摘要:
