# Source Monitoring Déficit in Neuropsychiatric Population

**NCT ID:** [NCT03886584](https://clinicaltrials.gov/study/NCT03886584)

## Key Facts

- **Status:** RECRUITING
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 300
- **Lead Sponsor:** Hôpital le Vinatier
- **Conditions:** Psychiatric Disorder
- **Start Date:** 2019-03-08
- **Completion Date:** 2026-07-31
- **CT.gov Last Update:** 2025-07-31

## Brief Summary

the investigators will measure source-monitoring ability in patients with several neuropsychiatric condition and in healthy controls appaired in age, sex and educational level. Source-monitoring will be measured thanks to internal- and reality-monitoring informatic tasks.The investigators hypothesized patients with fronto-temporal abnormalities would show more marked deficits than patients with only frontal abnormalities.

## Detailed Description

Source-monitoring abilities will be measured thanks to reality-monitoring testing (i.e. the ability to distinguish internal-generated events from external ones) and internal-monitoring testing (i.e. the ability to distinguish an imagined source from a performed one). A source-monitoring deficit have been demonstrated in patients with psychiatric conditions such as schizophrenia and seems linked to frontotemporal abnormalities (frontotemporal dysconnectivity and temporal hypoactivity). With a total of 150 patients, the investigators will include 30 patients per group: patients with pre-dementia stage Alzheimer, Alzheimer, Fronto-Temporal dementia, Lewy Body dementia or Parkinson and Bipolar Disorder, with the hypothesis that Bipolar Disorder patients will present less marked deficit. The investigators will recruit 150 healthy controls.

## Eligibility

- **Minimum age:** 18 Years
- **Maximum age:** 80 Years
- **Sex:** ALL
- **Healthy Volunteers:** Yes

```
Inclusion Criteria:

* Subjects who gave their free and informed consent;
* Men and women;
* Aged 18 to 80;
* Having normal or corrected vision;
* Mastering the French language (read and spoken);
* All subjects will not have a working memory deficit preventing the test from being passed (MMSE short version):AM patients should have a score of \<MMSE \<26; Patients with pre-dementia AD will be diagnosed according to Dubois criteria (Dubois et al., 2016); patients with early FTD will be diagnosed according to Rascovsky's criteria (Rascovsky et al., 2011); Patients with DCL will be diagnosed according to McKeith's criteria (McKeith et al., 2005), TBP patients will be diagnosed using DSM 5 criteria (Arlington VA, 2013).

Exclusion Criteria:

* Inadmissibility of the consent or refusal of the subject.
* Patients under guardianship
```

## Arms

- **Patients with with neuropsychiatric conditions** (EXPERIMENTAL) — In this arm, five groups :

* Patients with DFT, diagnosed according Racovsky criteria
* Patients with Lewi Body dementia, diagnosed according McKeith criteria
* Patients with pre-demential Alzheimer, diagnosed according Dubois criteria
* Patients with Alzheimer, diagnosed according MMSE
* Patients with bipolar disorder, diagnosed according DSM 5
- **Healthy subjects** (ACTIVE_COMPARATOR) — Healthy controls appaired in age, sex and educational level

## Interventions

- **Monitoring source test** (OTHER) — Internal- and external-monitoring correct responses and inversions

## Primary Outcomes

- **measure source memory performance** _(time frame: one year)_ — in patients with neuropsychiatric disorders with or without temporal involvement (pre-dementia Alzheimer's disease, Alzheimer's disease - AD, fronto-temporal dementia - DFT, Lewy body dementia - DCL and bipolar disorder - TBP) and healthy volunteers matched in age, gender, and level of education.

## Secondary Outcomes

- **measure the recognition of distractors** _(time frame: one year)_
