Portable Brain and Vision Diagnostic and Therapeutic System
A portable wireless neuromonitoring device can be used to diagnose and/or treat conditions of the brain and vision system. The device includes a sensor unit mountable on the head of a human subject and capable of recording signals from the brain in EEG and/or EFEG (electric field encephalography) mode, and the device can be used for simultaneous stimulus display and recording with latency of less than 1 millisecond. The device also includes electrodes that allow rapid set-up and measurement with low impedance contact with the scalp. The device can also be used in conjunction with virtual reality or alternate reality environments.
Systems and Methods for the Identification of Medical Conditions, and Determination of Appropriate Therapies, by Passively Detecting Acoustic Signals Generated from Cerebral Vasculature
The present specification describes a system for diagnosing or screening one or more pathologies in a patient. The system includes a headset with at least one microphone or accelerometer to passively receive vibrations generated by the cerebral vasculature of the patient's brain, computing devices coupled with the headset for processing the received vibrations to obtain a unique signal, and a signal analyzer to analyze the signal in order to determine if the data includes patterns uniquely indicative of at least one of tension headaches, migraines, depression, dementia, Alzheimer's disease, epilepsy, Parkinson's disease, autism, cerebral vasospasm and meningitis.
MULTIMODAL BRAIN SENSING LEAD
A medical lead with at least a distal portion thereof implantable in the brain of a patient is described, together with methods and systems for using the lead. The lead is provided with at least two sensing modalities (e.g., two or more sensing modalities for measurements of field potential measurements, neuronal single unit activity, neuronal multi unit activity, optical blood volume, optical blood oxygenation, voltammetry and rheoencephalography). Acquisition of measurements and the lead components and other components for accomplishing a measurement in each modality are also described as are various applications for the multimodal brain sensing lead.
Monitoring treatment compliance using patient activity patterns
Methods and systems for monitoring compliance of a patient with a prescribed treatment regimen are described. Patient activity is detected unobtrusively with an activity sensor at the patient location, and activity data is transmitted to a monitoring location. Patient speech detected during use of a communication system such as a mobile telephone by the patient may also be used as an activity signal. Patient activity and/or speech is processed at the patient location or monitoring location to identify activity parameters or patterns that indicate whether the patient has complied with the prescribed treatment regimen. The activity sensor and other components at the patient location may be incorporated into, or associated with, a cell phone, computing system, game system, or vehicle system, for example. The system may provide a report to an interested party, for example a medical care provider or insurance company, regarding patient compliance with the prescribed treatment regimen.
METHOD FOR SCREENING OF MOVEMENT DISORDERS
A method of screening a patient for a degenerative neurological disorder. The method can comprise the steps of: providing a tablet computer having a touchscreen to the patient, instructing the patient to draw a plurality of shapes, wherein each shape of the plurality of shapes is of varying complexity, recording at least one drawing characteristic for each shape drawn by the patient, mathematically analyzing the at least one drawing characteristic to determine an objective rating for each shape, analyzing the objective rating for each shape using a random forest comprising a plurality of decision trees to determine an objective probability that the patient has a neurological deficit, wherein the objective probability that the patient has a neurological deficit is the percentage of the plurality of decision trees which indicate a disease state.
Apparatus and related method to facilitate testing via a computing device
This disclosure relates to a device to mechanically and electrically connect with a touch screen computing device, such as a tablet computer. The device can include a platform that can be moved into and out of physical contact with a surface of a touch screen. During engagement with the surface, the moveable platform electrically interacts with the touch screen (e.g., via capacitive coupling) to enable detection by the touch screen of contact members (e.g., pegs) even in the absence of user contact with the pegs.
SYSTEMS AND METHODS FOR COMPREHENSIVE HUMAN MOVEMENT ANALYSIS
A method, system, and computer-readable medium receive module configuration settings to configure a customized human movement examination module for a human movement examination item. A patient is instructed with audio instructions associated with the customized human movement examination module. A single camera is controlled having progressive scan capabilities according to the module configuration settings to allow recording of a performance by the patient of the human movement examination item. The recorded data is analyzed based on the information provided by the single camera to measure human movement exhibited by the patient.
AUGMENTED REALITY DISPLAY SYSTEM FOR EVALUATION AND MODIFICATION OF NEUROLOGICAL CONDITIONS, INCLUDING VISUAL PROCESSING AND PERCEPTION CONDITIONS
In some embodiments, a display system comprising a head-mountable, augmented reality display is configured to perform a neurological analysis and to provide a perception aid based on an environmental trigger associated with the neurological condition. Performing the neurological analysis may include determining a reaction to a stimulus by receiving data from the one or more inwardly-directed sensors; and identifying a neurological condition associated with the reaction. In some embodiments, the perception aid may include a reminder, an alert, or virtual content that changes a property, e.g. a color, of a real object. The augmented reality display may be configured to display virtual content by outputting light with variable wavefront divergence, and to provide an accommodation-vergence mismatch of less than 0.5 diopters, including less than 0.25 diopters.
NON-INVASIVE MAGNETIC OR ELECTRICAL NERVE STIMULATION TO TREAT OR PREVENT DEMENTIA
Devices, systems and methods are disclosed for treating or preventing dementia, such as Alzheimer's disease. The methods comprise transmitting impulses of energy non-invasively to selected nerve fibers, particularly those in a vagus nerve, that modulate the activity of a patient's locus ceruleus. The transmitted energy impulses, comprising magnetic and/or electrical energy, stimulate the selected nerve fibers to cause the locus ceruleus to release norepinephrine into regions of the brain that contain beta-amyloids. The norepinephrine counteracts neuroinflammation that would damage neurons in those regions and the locus ceruleus, thereby arresting or slowing the progression of the disease in the patient.
PARETIC LIMB REHABILITATION METHODS AND SYSTEMS
Generator systems and methods are provided for generating a neuromuscular-to-motion decoder from a healthy limb. The generator system is configured to receive neuromuscular signals from neuromuscular sensors associated to predefined muscle/nerve locations of at least one pair of agonist and antagonist muscles/nerves of the healthy limb, obtained during performance by the person of a predefined exercise (defined by predefined exercise data) with the healthy limb; to receive motion signals from motion sensors associated to predefined positions of the healthy limb, during performance by the person of the predefined exercise with the healthy limb; and to generate the neuromuscular-to-motion decoder by mapping the neuromuscular signals to the motion signals over time using a mapping method. Rehabilitation systems are also provided for rehabilitating a paretic limb by using a neuromuscular-to-motion decoder produced by a generator system.
