Premorbid Personality Profile of Patients With Cognitive and Behavioral Disorders

Relationship Between Premorbid Personality Traits and Cognitive and Behavioral Disorders

Damages in frontal area present in neurodegenerative disease (frontotemporal degeneration, frontal variant of Alzheimer disease) and in psychiatric disease (bipolar disorder) can affect behavior and cognition including social cognition. Symptoms vary both quantitatively and qualitatively from disease to another and from person to person. It cannot be completely excluded that in some cases, factors of susceptibility such as premorbid personality traits lead to frontal fragility.

The study will assess the relationship between premorbid profile using NEO-PI 3 inventory and cognitive and behavioral/psychobehavioral manifestations in patients with behavioral variant of frontotemporal disorder (bvFTD), phenocopy frontotemporal dementia (phFTD), frontal variant of Alzheimer disease, bipolar disorder characterized with frontal damages.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Behavioral variant of frontotemporal disorder (bvFTD); A group of participants who fulfill Rascovsky criteria (2011) for behavioural variant Frontotemporal Dementia	Other: Submission of the NEO-PI-3 questionnaire; The questionnaire contains 240 statements. For each statement, the patient chooses the answer that best corresponds to their choice (FD: strongly disagree - D: disagree - N: neutral - A: agree - FA: strongly agree).; Other: Submission of the Interpersonal Reactivity Index questionnaire (IRI); The test assesses two cognitive and two affective components of empathy that influence each other and affect attitudes and behaviors toward others.
Phenocopy frontotemporal dementia (phFTD); A group of participants who fulfill who fulfill Rascovsky criteria (2011) for possible behavioural variant Frontotemporal Dementia and have no imaging abnormalities.

For each statement, the patient chooses the answer that best corresponds to their choice (FD: strongly disagree - D: disagree - N: neutral - A: agree - FA: strongly agree).; Other: Submission of the Interpersonal Reactivity Index questionnaire (IRI); The test assesses two cognitive and two affective components of empathy that influence each other and affect attitudes and behaviors toward others.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Premorbid personality traits	Premorbid personality traits will be assessed by the NEO- NEO Personality Inventory-3 (NEO-PI-3). The NEO PI-3 measures the five major domains of personality: Neuroticism, Extraversion, Openness to experience, Conscientiousness and Agreeableness. Each domain is defined by 6 facets. NEOPI-3 includes 240 items and responses are made on a 5-point Likert -type scale ranging from strongly Disagree to strongly agree. The NEOPI 3 will be completed by a caregiver who has known the patient in the 10 years preceding the disease onset.	Baseline

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Interpersonal Reactivity Index (IRI)	IRI is a 28-item questionnaire measuring 4 aspects of empathy : perspective-taking, fantasy, empathic concern, personal distress. Each answer is rated from 1 (does not describe me well) to 5 (describes me very well).	Baseline
