Assessment of Hedonic and Motivational States in Major Depression ( MOODDIS)

Plain-language summary
Major depression is a frequent psychiatric disorder with an estimated lifetime prevalence of 16-17% in the general population. Although its pathophysiology is not completely understood, a large body of literature pleads for a causative role of disturbances in reward processes, referring to: i) the hedonic sensation (i.e. "liking") defined by the pleasure felt after exposure to appetitive stimuli, and ii) the motivation (i.e. "wanting") represented by the ability to initiate and maintain behavioral responses oriented toward appetitive stimuli. the investigators have therefore developed and tested a new experimental computer-based and easy-to-use test intended to provide an objective and quantitative measurement of both hedonic and motivational states in humans. According to the task, the subjects are asked to view and to compare two stimuli, an appetitive one (food pictures) and its devalued counterpart (food pictures in greyscale), at each trial, assessing either the size (task A) or the duration of presentation (task B). From these considerations, the present project aims at using our novel tool to: i) assess the hedonic and motivational state in subjects with major depression, ii) compare their responses with healthy volunteers. The present project should demonstrate that the behavioral tests validated in our laboratory are relevant experimental tools for the diagnostic/clinical assessment and for the phenotypic characterization of depressed patients. The application of the test in the therapeutic context could add further information about the efficacy and relevance of the chosen therapy.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

. to be free from any history of psychiatric disorder (substance abuse or alcohol abuse, dependence, mood disorders, etc.) that may require the prescription of long-term psychotropic treatment;
Exclusion criteria
. to have a previous history of somatic disease (hypertensive heart disease, Raynaud's syndrome, diabetes, adrenal insufficiency, Cushing's syndrome, peripheral neuropathy, epilepsy ...) or requiring long-term corticosteroid therapy;
. to experience serious visual disturbances affecting the visual perception of colors;
. to meet the DSM-5 diagnostic criteria for a primary psychiatric disorder such as bipolar disorder, schizophrenia, substance abuse / dependence or alcohol abuse, except for social phobia and generalized anxiety disorder that are commonly comorbid to major depression;
. to exhibit a moderate or high suicidal risk, assessed by using the corresponding section of the so-called structured diagnostic psychiatric interview "Mini International Neuropsychiatric Interview" (M.I.N.I. 6.0);
. to be exposed to the initiation of an antidepressant treatment with either a selective serotonin reuptake inhibitor or a dual serotonin-norepinephrine reuptake inhibitor within the week prior to the study or to be exposed to a change in the daily dosage of such an ongoing antidepressant treatment within the week preceding the study due to its potential sedative and orexigenic properties;
. to be exposed to an antidepressant treatment with antagonists at the presynaptic alpha-2 norepinephrine receptors or with tricyclic agents within the week prior to the study due to their potential sedative and orexigenic properties related to their anti-H1 pharmacological profile;
. to be exposed to the initiation of anxiolytic/hypnotic treatment within the week before the study or to be exposed to a change in the daily dosage of such an ongoing anxiolytic/hypnotic treatment within the week prior to the study due to its potential sedative properties in relation with its GABAergic activity;
. to be exposed to an antipsychotic treatment within the week prior to the study due to its potential sedative and orexigenic properties related to its anti-H1 pharmacological profile;
