Abstract: The present invention relates to a cognitive impairment determination apparatus (10), comprising: an input unit (20): a processing unit (30, 120); and an output unit (40). The input unit is configured to provide the processing unit with a plurality of first task trial results, wherein the plurality of first task trial results is generated by a patient having conducted a plurality of trials of a first task. The processing unit is configured to determine an index for the patient, wherein the determination of the index comprises a calculation of a representation of fluctuations in the plurality of first task trial results. The processing unit is configured to determine that the patient should undergo a scan of the brain, wherein the determination comprises utilization of the index for the patient. The output unit is configured to output information that the patient should undergo the scan of the brain if the processing unit determines that the patient should undergo the scan of the brain.

Abstract: Embodiments described herein relate to automated digital prospective memory tests. In various embodiments, working memory instructions may be provided (402) that prompt a subject to perform working memory task(s). Additional instruction(s) may also be provided (404) prompting the subject to perform prospective memory task(s). Each additional instruction may prompt the subject to perform a respective prospective memory task after a predetermined time interval. During the predetermined time interval, the subject's performance of the working memory task(s) may be monitored (406) to determine a measure of engagement. An actual time interval between provision of a given additional instruction and performance of the prospective memory task prompted by the given additional instruction may be determined (408). If the measure of engagement satisfies a criterion, a certified prospective memory measure of the subject, calculated based at least in part on the actual time interval, may be provided (412).

Abstract: The invention relates to a system and a method for creating an ambient experience for a person, particularly for a patient to be examined in a medical imaging device having a bore into which a patient table can be moved. In a preferred embodiment, the system comprises a display (30) for displaying an image content such as a video for the relaxation of a patient, and an illumination device (40) for illuminating the surroundings with polarized light. Moreover, it comprises a viewing aid, particularly a pair of glasses (20), that is designed to at least partially block light from the illumination device (40) while letting light from the display (30) pass. The viewing aid (20) may for example comprise a polarization filter (23) that lets linearly polarized light (4) from the display (30) pass while blocking light from the illumination device (40) that is polarized in a perpendicular direction. A patient on the patient table can thus view the display (30) without being disturbed by an illumination of the surroundings.

Abstract: A system and method are provided for use in the assessment of an attentional deficit. During the assessment, a test image is presented to a subject on a display. A camera image is obtained from a camera which is indicative of a geometric relation between the head of the subject and the display during the assessment. The camera image is analyzed to determine a deviation in the geometric relation between the head of the subject and the display from a reference geometric relation. Deviation data is then generated and output which is indicative of the deviation. Advantageous uses of the deviation data include providing visual feedback to the user, adjusting the test image, and taking the deviation into account when processing test data of the assessment. Advantageously, the need for a trained professional to be present during the assessment is reduced or avoided.

Abstract: A method and system for assessing a subject using fMRI analysis of the brain activity of a subject while they perform a set of cognitive tasks. For each task, a first level of performance in completing the task is derived. For at least some of the tasks which have been completed to a satisfactory level of performance, it is assessed if any of those tasks showed increased activity, above a threshold, of a region of the brain different to a region of the brain associated with the task. For those tasks, a further fMRI analysis is carried out while they perform a further cognitive task but with additional cognitive loading. The fMRI analysis and the further fMRI analysis are compared. This for example enables determination that a patient is using compensation mechanisms to complete the cognitive tasks.

Abstract: A method and apparatus for use as part of diagnostic analysis of the psychiatric or neurological health of a patient based on use of a normative database of fMRI data results and cognitive task results for a population of prior patients. Embodiments propose to acquire fMRI data of a particular set of one or more regions of the brain of a patient while the patient is performing a cognitive task, and to record at the same time results of the patient's performance in the cognitive task. A combination of both the cognitive task results and the fMRI data for the brain regions is used to provide an indicator as to a cognitive health status of the patient. More particularly, a normative database of fMRI data results and cognitive task results for a population of patients is used as a reference. This may store results both for healthy patients and pathological patients, to provide a normal and abnormal reference.
