Description

This invention relates to a device for neuropsychological evaluation and rehabilitation of mental disorders. Neuropsychology is the study of the relationship between cognitive activity, or mental activity, and the corresponding brain states, or states related to the brain or brain parenchyma. The brain, composed of the brainstem, diencephalon, and cerebrum, forms the central nervous system together with the spinal cord. Neuropsychology assesses cognitive function using psychometric and physiological tests in cases of structural or functional impairment of the central nervous system, and rehabilitates these deficits. Even with advances in brain imaging technology, limitations remain in spatial resolution (electroencephalography, magnetoencephalography, transcranial magnetic stimulation) and temporal resolution (magnetic resonance imaging, positron emission tomography, diffusion tensor imaging). Furthermore, the interpretation of the results depends on the neuropsychological questions at the time of imaging. Therefore, neuropsychology is an important field of study at the intersection of multiple medical and non-medical disciplines, crucial for understanding the functional mechanisms of cognition and the brain. Visual neuropsychology is a field that specializes in the study of the cognitive and neurological aspects of vision, i.e., neurovision. Neurovision includes visual pathways (traditionally afferent pathways) extending from the retina of each eye to various brain regions, and motor pathways (traditionally efferent pathways) extending from various brain regions to the extraocular and intrinsic eye muscles of each eye. Humans possess at least five visual pathways: the retino-occipital lobe pathway, the retino-superior colliculus (or retino-tectum) pathway, the retino-pretectal pathway, the retino-hypothalamic pathway, and the accessory visual system. Motor pathways involve motor neurons and premotor centers in the brainstem, as well as higher-level brain regions that control them, such as the superior colliculus (traditionally the superior colliculus or anterior quadratic tubercle), the basal ganglia, and some cortical regions (Coubard, 2011; Coubard, 2015). These neurovisual brain circuits (visual and motor pathways) together account for approximately 60% of the entire brain and are naturally involved in cognitive functions other than neurovision. From this configuration, the following physiological principle can be derived: by appropriately utilizing the visual and motor pathways of neurovision, it is possible to influence various functions in which they interact (Coubard, 2015). This device is shown in the seven drawings created by the inventor. Figure 1 shows a two-dimensional side view of the device. Figure 2 shows a three-dimensional top view and a side view of the device. Figure 3 shows a top view of the mathematical form of this device. Figure 4 shows various visual stimulation methods. Figure 5 shows various visual stimulus filtering methods. Figure 6 shows the neuropsychological assessment steps. Figure 7 shows the neuropsychological evaluation process. As shown in Figures 1(1), 2(1), and 3(1), the device is equipped with a lamp positioned in the patient's sagittal plane, the length of which varies from 10 centimeters to 200 centimeters, including the depth of the eyeglass bridge, and is used for near and far vision. The lamp is equipped with a graduated ruler for manually or electronically adjusting the viewing distance of the stimulation screen, bar, filter screen, and hybrid screen. While this device can accommodate all lamp lengths, in practical applications it is preferable to use different devices for different lamp lengths. By definition, the ramp allows each of its supporting components (bar, filter screen, hybrid screen, and stimulation screen) to slide without restriction. According to this definition, a lamp does not fall under any of the following categories, where the elements remain fixed: “rod” (FR1), “beam” (FR2), “hollow beam with darkroom” (FR3), or “horizontal beam” (FR4, EU1). The lamp is supported by the legs shown in Figures 1(7) and 2(7), and is placed on the floor at long viewing distances, on a table at intermediate and near viewing distances, and folded and held by the patient at near viewing distances. The leg portion is detachable vertically to allow contact between the patient's nasal bridge and the eyeglass bridge. The lamp is movable in all spatial planes thanks to its legs, which allows for... - Yaw rotation to the left or right around the **longitudinal axis (anterior-posterior or posterior-inferior direction)**, which is the intersection of the sagittal plane and the frontal plane. - Pitch rotation upward or downward around the transverse axis (horizontal direction), which is the line of intersection of the frontal plane and the horizontal plane. - Roll rotation to the left or right around the anterior-posterior axis (rostrochordal axis), which is the intersectio
