Brief Summary

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).

Outcome Measures

Primary Outcomes (1)

  • rate of inappropriate behavioural intentions

    It is measured by the REALSoCog task through a question asking the participant to specify his behavioral intention in the case where he would have declared his intention to act in front of the social situation presented. These questions are asked for each social situation presented, i.e. for a total of 16 situations

    1 hour and a half

Secondary Outcomes (3)

  • Assessment of Moral cognition

    1 hour and a half

  • Evaluation of Empathy and emotional reactivity

    1 hour and a half

  • Assessment of theory of mind

    1 hour and a half

Study Arms (2)

Patients

EXPERIMENTAL

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

Other: REALSOCOGOther: BCS

Relatives

OTHER

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

Other: Hetero-questionnaires

Interventions

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.

Also known as: neuropsychological test
Patients
BCSOTHER

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.

Also known as: Social-Cognition Battery
Patients

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.
