Unlike pencil-and-paper tests, virtual reality is useful to assess large-scale navigation strategies in patients with brain injury or schizophrenia, or in the context of ageing and dementia. Better knowledge about both the impact of the different aids and the cognitive processes involved is essential for the use of aids in neurorehabilitation.

Although spatial representations probably differ between the real and virtual environment, virtual reality remains a trusty assessment tool for spatial abilities.

AbstractEvery year, tens of thousands of people fall victim to one of invalidating neurological pathologies. Acquired brain injury leads to cognitive impairment and heavy loss of autonomy. Rehabilitation interventions are needed to enable people to recover capacity and return to Instrumental Activities of Daily Living (iADL), such as grocery shopping. Unfortunately, the resources made available in cognitive rehabilitation are insufficient for the growing needs of victims of brain damage. The goal of the AGATHE project is to develop a tool that will provide therapists with an innovative means of dealing with cognitive rehabilitation and offer patients customized rehabilitation sessions, on the basis of simulated iADL. AGATHE fits into accessibility prospects of the tool (for everyone, everywhere and anywhere) and reduction of the cost of rehabilitation. AGATHE allows the strengthening and diversification of skills and expertise of the project's clinical and research partners as well as the opening of a new application field to the technology of the industrial partners. Initial tests of the AGATHE tool have been performed among therapists and patients after brain injury in order to validate usability issues. Perspective of efficacy trials has been identified and development projects are explored.

The differential cognitive mediating effects for a similar everyday-like memory pattern are discussed by highlighting the need for more cautious interpretations of cognitive mechanisms behind similar behavioral patterns in different populations especially in clinical and rehabilitation settings.
