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.

A shear force generating device includes a shear-force generator structured for exerting a shear force at to each volume element of a sample of body fluid or tissue and a native conformation prion protein arranged in a container. A controller controls the shear-force generator to exert a shear-force of at maximum 10% of one shear-force intensity to each volume element of the sample arranged in the container. A light source is directed into the container. An optical detector is arranged to detect light emanating from the container. The detector is coupled to a computer including code to analyze light detected by the optical detector as a measure for the content of aggregated prion protein by comparing the light detected to a Reference Information Database.

The present invention generally relates to apparatus, software and methods for assessing ocular, ophthalmic, neurological, physiological, psychological and/or behavioral conditions. As disclosed herein, the conditions are assessed using eye-tracking technology that beneficially eliminates the need for a subject to fixate and maintain focus during testing or to produce a secondary (non-optical) physical movement or audible response, i.e., feedback. The subject is only required to look at a series of individual visual stimuli, which is generally an involuntary reaction. The reduced need for cognitive and/or physical involvement of a subject allows the present modalities to achieve greater accuracy, due to reduced human error, and to be used with a wide variety of subjects, including small children, patients with physical disabilities or injuries, patients with diminished mental capacity, elderly patients, animals, etc.

Provided are systems and methods for medical diagnosis. The systems and methods may identify a coherence between paired sensor data respectively measured from a first sensor attached to a head of a subject and a second sensor attached to a body part of the subject. The systems and methods may determine an amount of volition in the subject's body based on the coherence. The systems and methods may determine a diagnosis or a treatment plan for a subject based on the amount of volition. The system and methods may be used to track interaction between individuals in a clinical setting or in a social group.

An earbud system integrates real-time EEG monitoring with audio playback. Using specialized silicone electrodes, it captures and interprets EEG data, serving as a passive and continuous tool for screening neurological conditions. This allows for on-the-spot brain monitoring while retaining conventional earbud functions. It can particularly be used in medical scenarios, like open brain surgery, where traditional EEGs cannot be integrated during the operation itself. The system aids emotional balance, stress relief, and neurostimulation, bolstering brain health, mood enhancement, and relaxation. Its applications span wellness for therapeutic interventions and entertainment for tailored content using biometric feedback. This invention broadens traditional earbud capabilities, merging biometrics, health tracking, and customized audio suggestions.

A computer-implemented cognitive assessment tool is provided for assessing cognitive ability of an individual while multi-tasking. In one embodiment, a computer processing system on which the tool is implemented may receive form the individual first responses to a first task and second responses to a second task, where the first task and the second task are presented to the individual simultaneously. The system may determine that the first task and the second task are performed by the individual based on the first responses and the second responses, and compute a cognitive measure using one or both of the first responses and the second responses. Further, computing the cognitive measure may be based on performance measures of one or both of the first responses and the second responses. Based on the cognitive measure, the system may output a cognitive assessment to the individual.

Provided are a biosignal visualizing system, which may easily learn a biosignal, may easily make a diagnosis, and may perform analysis in real time, and an effective pattern extracting method using the same, in order to determine a disease using a biosignal via deep learning.

A system and a method measure volumetric changes of brain structures. The method includes initializing an intensity value of all voxels of a 3D voxel dataset representing the brain of a subject to an initial value preferentially equal to 0. For all voxels that belong to a segmented brain structure for which reference data of a longitudinal reference model exists, automatically executing the following steps: calculating a deviation of a volume change for the segmented brain structure from the longitudinal reference model, normalizing the deviation to obtain a quantitative value of the volume change on a same scale for voxel's belonging to different brain structures; and setting the intensity value of the voxels to the previously obtained quantitative value Q. The voxels of the 3D voxel dataset are displayed in a form of a longitudinal deviation map.

The present specification discloses systems and computer implemented assessment methods including a system and method of assigning an individual to a group participating in a clinical study regarding a psychotic disorder, a system and method of determine whether and what type of psychotic disorder an individual may be suffering from; and a system and method of recommending a therapy to treat an individual with a psychotic disorder. All disclosed systems and computer implemented assessment methods use a non-invasive computational device-based test that uses a graphical user interface to measure a latent inhibition response of an individual to calculate a latent inhibition score and assess working memory. The latent inhibition score determines whether the individual exhibits an attenuated latent inhibition response, a normal latent inhibition response or an enhanced latent inhibition response.

A body monitoring system is designed for patients of varying needs with patients at risk for seizures, epilepsy, stroke, heart attack, bedsores, dementia, mental disorders, Old aged people on elderly, children specifically hyperactive ones. This system provides the user the control by online observation and activities algebra sum table sand database. The system has two warning systems: in APP and cell phone in the emergency. A plurality of sensors measuring angle and movement and acceleration in the XYZ axes in combination with a plurality of GPS sensors and GPS boundary makers and a heart rate sensor is used. Show and control and monitoring positions of the body during resting and the time and place activities and body movement of patients the states and tensions have problems psychological. Online display current status of patient and saving the states and conditions of the patient.
