Applicability of an immersive virtual reality system to assess egocentric orientation of older adults.

Background: Spatial orientation is a cognitive domain frequently compromised in patients with Alzheimer disease (AD) and may be one of its first clinical manifestations. Some studies have shown that allocentric integration with egocentric spatial information seems to be impaired in this pathology. There is no consensus on how best to assess spatial orientation and traditional tests lack ecological validity, but, recently, virtual reality (VR) has provided new opportunities for this assessment.

Applicability of an immersive virtual reality system for assessing route learning in older adults.

Unlabelled: Spatial orientation is defined as the ability to find one's way around an environment, follow familiar routes, recognize places, and learn new routes. Spatial disorientation is one of the early symptoms of Alzheimer's disease (AD), and traditional cognitive evaluation lacks ecological validity. Therefore, new assessment methods are needed for the early identification of this cognitive impairment.

Two Immersive Virtual Reality Tasks for the Assessment of Spatial Orientation in Older Adults with and Without Cognitive Impairment: Concurrent Validity, Group Comparison, and Accuracy Results.

Objective: Spatial disorientation is common in Alzheimer's disease (AD), Mild Cognitive Impairment (MCI), and preclinical individuals with AD biomarkers. However, traditional neuropsychological tests lack ecological validity for the assessment of spatial orientation and to date, there is still no gold standard. The current study aimed to determine the validity and accuracy of two virtual reality tasks for the assessment of spatial orientation.

Immersive Virtual Tasks With Motor and Cognitive Components: A Feasibility Study With Young and Older Adults.

Objective: To analyze the feasibility, safety, and acceptability of immersive virtual tasks.

Methods: The authors recruited 11 young adults and 10 older adults. The participants performed three virtual reaching tasks while walking on a virtual path.

Two new virtual reality tasks for the assessment of spatial orientation Preliminary results of tolerability, sense of presence and usability.

Unlabelled: Spatial orientation is a cognitive domain frequently impaired in Alzheimer's Disease and can be one of its earliest symptoms.

Objective: This paper describes the results of tolerability, sense of presence and usability of two immersive virtual reality tasks for the assessment of spatial orientation, using VR headset in adults.

Methods: 31 healthy adults recruited from university and the local community performed two experimental immersive virtual reality tasks of spatial orientation: the SOIVET-Maze for the assessment of allocentric to egocentric spatial abilities and the SOIVET-Route for the assessment of spatial memory and landmark recognition.
