Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

It is now established that disturbances in social cognition are frequent in neurology and that they contribute to the development of social conduct disorders. Their assessment is therefore essential, particularly in order to propose early and adapted care. However, this assessment remains limited today. A new serious game-type test, REALSoCog, has been developed to address the shortcomings of current tools and to highlight disturbances in social behaviors. The latter are not always observed in consultation although they are often reported by caregivers. The objective of this research is therefore to validate the REALSoCog task in a pathological population (currently being standardized in the general population: CER-U, IRB N°: 00012020-115). The clinical interest of this task will be tested with a group of patients suffering from a neurodegenerative disease (Alzheimer's disease (AD), dementia with Lewy bodies (DCL), fronto-temporal lobar degeneration (FTD)) in order to assess its sensitivity and specificity in the detection of social-cognitive disturbances, and in particular in terms of social behaviors (detection of social behavioral disorders reported in daily life). The objective is also to document the socio-cognitive profiles in the mentioned diseases thanks to a more ecological test, and to better understand the links between socio-cognitive processes on the one hand, and individual characteristics on the other hand (e.g. mood and social participation).

Patients

Patients suffering from a neurodegenerative disease (Alzheimer's disease (AD), dementia with Lewy bodies (DCL) or fronto-temporal lobar degeneration (FTD))

Group Type EXPERIMENTAL

REALSOCOG

Intervention Type OTHER

Patients will be asked to perform the REALSoCog serious game-type social cognition assessment task developed by the LMC2 laboratory (UR 7536). Their performance will be compared to those of control individuals recruited in parallel (independant clinical study: CER-U, IRB N°: 00012020-115). Participants will be asked to think about 16 social situations (6 control situations and 10 experimental situations) encountered in a virtual environment representing a city. REALSoCog can be used on a laptop computer, without any additional technical device.

BCS

Intervention Type OTHER

Social-cognitive tasks from the BCS (Ehrlé et al., 2011) will also be offered to patients to test the concurrent validity of REALSoCog. This battery assesses social cognition. It includes paper-and-pencil tasks.

Relatives

Caregivers or relatives of included patients, having regular contact with the patient (≥ 2 times per month).

Group Type OTHER

Hetero-questionnaires

Intervention Type OTHER

Hetero-questionnaires assessing patients' social behavior will be transmitted to their relative or primary caregiver (Godefroy \& le GREFEX, 2008; Gury and Ehrlé, in progress of validation) in order to verify the concurrent validity of REALSoCog. These hetero-questionnaires aim to identify and quantify the presence of social skills and behaviour disorders.
