The present invention provides non-invasive methods for diagnosing Alzheimer's disease in a living human subject. One method employs a non-invasive automated apparatus which can continuously monitor pupil diameter size over time; repetitively measure pupil diameter size over time for a pre-chosen duration ranging from about less than 1 second to about 5 minutes; and cumulatively record size information as it is obtained over time. A second method employs an apparatus which can repetitively measu...

A system and method for performing a vision examination includes displaying a series of visual stimuli for observation by a patient and detecting the patient's visual evoked potentials in response to the visual stimuli. Electrical signals representative of the visual evoked potentials for each stimulus of each series of visual stimuli displayed is amplified, converted to digitized data, recorded and measured. The measured visual evoked potential data is then evaluated and compared to certain pre...

The present invention relates to an electrode detector, which comprises a contact electrode part adjustable to tissue, or being in touch with it and which contact electrode part is for monitoring biopotential or other physical magnitude, a conducting wire (2) attached to the contact electrode part, electroconductive material, non-electroconductive material and electronics processing the signal. The electrode detector in accordance with the invention comprises a ball-shaped or almost ball-shaped ...

There are provided a device which can measure a reaction performance of a neurotransmission system and that of a muscle expansion/contraction system in a specific body part easily, and gives a direction that a muscle in a specific body part is to be in an unreacted state by muscle unreacted state directing means, gives a direction that the muscle in the part is to be shifted into a reacted state by muscle reacted state directing means, continuously measures impedance and time until the reaction ...

Method and system for detection and treatment of visual attention deficit is suggested. The method is based on exposing a patient to a visual display, capable to generate various images suitable for use as stimuli and to run the stimuli with a required frequency in front of the patient. Following the training program, the patient's performance becomes considerably improved both in terms of display test and in daily reading tasks.

Apparatus is provided for high frequency ultrasound examination of the anterior segment of a patient's eyes. A liquid bath is established about a first eye of the patient to be examined. A fixed ultrasound transducer is placed in contact with the liquid bath and directs the beam of ultrasound energy to the first eye and receives echoes of the ultrasound energy. A fixation source is juxtaposed to the second eye of the patient and displays a fixation target. A controller operates the fixation sour...

A method for measuring perception of an observer comprises a) selecting a first, second, and third stimulus and presenting the stimuli to the observer; b) determining observer-defined fourth stimulus such that the observer perceives the fourth stimulus to be related to the third stimulus in the same way as the observer perceives the second stimulus to be related to the first stimulus; c) selecting a new first, second, and third stimulus, at least one of the new stimuli corresponding to a stimulu...

A device for the acquisition of coordinative abilities of a test person, allows different tests that test different coordinative abilities of the test person to be executed with the aid of a control unit. The control unit evaluates the individual test results and combines them to form a relevant quantitative overall assessment of the coordinative competence of the test person. This overall assessment is presented via a corresponding output unit, such as a screen.

The present invention provides a method and apparatus for implementing a training regimen which alleviates exaggerated sensory, perceptual, cognitive and/or emotional response problems. For example, in the aural domain, some autistic individuals are hypersensitive to one of the senses, e.g., sound. As discussed above, sounds at the specific frequency can cause discomfort to these autistic individuals even when presented at an intensity level which normally is not perceived as being too loud by m...
