Problems solved by technology

The problems with such diagrams are one of: scaling images for proper and constant linearization, contrast levels, and inability to establish a perceptual signature as described below because both static and dynamic stimuli are required

Embodiment Construction

[0023] refer to figure 1 , schematically shows a device 100 for measuring mild sensory impairment (MPI).

[0024] Apparatus 100 for measuring mild sensory impairment, comprising a generator of a stimulus applied to a human subject, the stimulus having at least one parameter. The stimulus generator includes a box-shaped housing 110 and a screen 112 mounted in the box-shaped housing 110 for displaying images, more specifically, visual stimulation. For example, the screen 112 may include an LCD (Liquid Crystal Display) screen, a plasma screen, AMLCD, LCOS, OLED, MEMS, or the like. Although the stimulus generator of device 100 may include, for example, figure 1 A single screen 112 is shown in , but this single screen 112 could also be replaced by two separate screens (not shown), including a first screen seen by the left eye 116 of the human subject 114 and the human subject's 114 screen. The second screen seen by the right eye 118 of the recipient 114.

Abstract

A device and method for measuring mild perceptual impairment of a human subject, in which a stimulus having at least one parameter is applied to the human subject. The human subject produces a response to the stimulus indicative of a perception by the human subject of the at least one parameter of the stimulus. The response of the human subject is then processed in view of determining if the human subject suffers from mild perceptual impairment.

Description

technical field [0001] The present invention relates to a device and method for measuring mild perceptual impairment (MPI) in human subjects, which can be used, for example, for screening, monitoring and / or Diagnostic measures of neurobiological alterations including brain trauma, Alzheimer's disease and autism. Background technique [0002] Studies have been conducted for many years to detect early changes in perception caused by subtle neurobiological alterations (NBAs), such as normal aging, neurotoxicity, glaucoma, and more recently, autism, x-ray syndrome (fragile x), mild brain injury and stroke. [0003] The underlying reason for these studies is to fill a gap in scientific knowledge about perceptual function, which lies between basic sensory measures (such as visual acuity) and high-level cognitive measures (such as neuropsychological profiles). Basic sensory measures are used to establish attenuation of the peripheral sensory mechanisms of the eyes and ears, while...
