This study aims to develop and validate a sensitive and non-invasive eye-tracking software application. This study will obtain participant responses to brief cognitive tests designed to evaluate several key functions known to be affected by neurological disorders and non-invasive eye movement measurements in response to visually presented stimuli during specifically designed eye-tracking tests. The study data will be used to develop machine learning algorithms and validate a software application intended to track the progressive component of neurological disorders and associated cognitive changes.

Symbol Digit Modalities Test (SDMT) score, one time, at the day of enrolment.
The SDMT is used to assess divided attention, visual scanning, tracking and motor speed. Using a reference key, the examinee has 90 seconds to pair specific numbers with given geometric figures. Scoring involves summing the number of correct substitutions within the 90 second interval.
Time frame: Baseline
Brief International Cognitive Assessment for MS (BICAMS) score, one time, at the day of enrolment.
The BICAMS is a battery of tests recommended by multiple sclerosis (MS) experts to monitor MS-related cognitive impairment. It includes the Symbol Digit Modalities Test (SDMT), the California Verbal Learning Test-2 (CVLT2) and the Brief Visuospatial Memory Test-Revised (BVMT-R)
Time frame: Baseline
Multiple sclerosis functional composite (MSFC) score, one time, at the day of enrolment.
A clinical trial outcome measure of assessing the severity of multiple sclerosis (MS) primarily. used in research. The score is based on a combination of timed tests of walking, arm function, and cognitive ability. It is a three-part, standardized, quantitative, assessment instrument for use in clinical studies, particularly clinical trials, of MS. The MSFC can produce scores for each of the three individual measures as well as a composite score.
Time frame: Baseline
The Montreal Cognitive Assessment (MoCA) score, one time, at the day of enrolment.
The Montreal Cognitive Assessment (MoCA) is a brief 30-question cognitive screening test designed to assist Health Professionals in the detection of mild cognitive impairment and Alzheimer's disease. It assesses different cognitive domains: attention and concentration, executive functions, memory, language, visuoconstructional skills, conceptual thinking, calculations, and orientation. Scores on the MoCA range from zero to 30, with a score of 26 and higher generally considered normal.
Time frame: Baseline
The Mini-Mental State Exam (MMSE) score, one time, at the day of enrolment.
The Mini-Mental State Exam (MMSE) is a widely used test of cognitive function among the elderly, it includes tests of orientation, attention, memory, language and visual-spatial skills. It consists of a series of questions and tests that can be used by clinicians to help diagnose dementia and to help assess its progression and severity.
Time frame: Baseline
The Controlled Oral Word Association Test (COWAT) score, one time, at the day of enrolment.
The Controlled Oral Word Association Test from the Halstead-Reitan Neuropsychological Battery is a verbal fluency test in which participants are asked to say as many words as possible from a given category and in a specified timeframe (typically 60 seconds).
Time frame: Baseline
The Trail Making Test (TMT) Parts A & B score, one time, at the day of enrolment.
The Trail Making Test (TMT) is a neuropsychological test that provides information on visual search, scanning, speed of processing, mental flexibility and executive functions. The TMT consists of two parts. TMT-A requires an individual to draw lines sequentially connecting 25 encircled numbers distributed on a sheet of paper. Task requirements are similar for TMT-B except the person must alternate between numbers and letters (e.g., 1, A, 2, B, 3, C, etc.). The score on each part represents the amount of time required to complete the task.
Time frame: Baserline
The Hopkins Verbal Learning Test-Revised (HVLT-R) score, one time, at the day of enrolment.
The Hopkins Verbal Learning Test (HVLT-R) is a neuropsychological test that provides information on verbal learning and memory. The assessment consists of memorization of a list of words to test the ability to recall immediately after memorization (immediate recall) and after a 20-minute delay (delayed recall).
Time frame: Baseline
The Functional Assessment of Cancer Therapy - Cognitive Function (FACT-Cog), one time, at the day of enrolment.
The Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog), currently in its third version, is a questionnaire that evaluates patients' self-reported perceptions of their cognitive abilities and the effects of these cognitive changes on their Health-related quality of life (HRQOL).
Time frame: Baseline
The Beck Anxiety Inventory (BAI), one time at the day of enrolment.
The Beck Anxiety Inventory (BAI) consists of 21 self-reported items (four-point scale) used to assess the intensity of physical and cognitive anxiety symptoms during the past week. Scores may range from 0 to 63: minimal anxiety levels (0-7), mild anxiety (8-15), moderate anxiety (16-25), and severe anxiety (26-63).
