PHYDDOPA: Neurophysiological Markers in the Depressive Episode Characterized by Anhedonic Drug Resistance: Evaluation of Motor Skills and P300 Wave
Study Details
Study Description
Brief Summary
Depression is currently the leading cause of disability and suicide death worldwide. Several studies, however, have shown that a significant proportion of patients do not respond to standard antidepressants, especially since their symptomatology is dominated by anhedonia or psychomotor retardation reflecting central dopaminergic dysfunction. In order to improve the efficiency and speed of the antidepressant response, it seems essential to highlight this dopaminergic dysfunction, by defining a P300 wave profile specific to the subtype of depressed patients with anhedonic phenotype to whom personalized treatment targeting dopaminergic transmission could in the future be proposed earlier. The investigators therefore wish to highlight an increase in the latency time of P300 and a modification of motor skills (of the walking cycle and of the movement of the hands), without modification of the dopaminergic transmission measured by PETScan, specific to the sub-type of depressive patients, resistant to at least 2 antidepressants of different classes with an anhedonia score> 5/14 on the SHAPS scale. The increased latency of P300 could then be used in the future as a predictive biomarker of resistance to conventional antidepressant treatments specific to this population of anhedonic depressed patients

Outcome Measures
Primary Outcome Measures
- Difference between latency of P300 wave during encephalogram [1 hour after inclusion]
Secondary Outcome Measures
- Difference in walking speed during an 8 meter-walk test between the group of patients with bipolar drug-resistant depression of the anhedonic type and the other groups of subjects [2 hours after inclusion]
- Stride length variation during an 8 meter-walk test between the group of patients with bipolar drug-resistant depression of the anhedonic type and the other groups of subjects [2 hours after inclusion]
- Difference in presynaptic fixation of 18-Fluorodopa during positron emission tomography between the group of patients with drug-resistant bipolar depression of the anhedonic type and the other groups of patients [4 hours after inclusion]
- Difference in the apathy assessment score performed by the Starkstein Apathy Scale (SAS) between the group of patients with drug-resistant bipolar depression of the anhedonic type and the other groups of subjects [30 minutes after inclusion]
Starkstein Apathy Scale (SAS) is scored from 0 to 42 42 = maximum severity of apathy ; Score <14 define a absence apathy Score ≥14 define the presence of a clinically significant apathy
- Difference in frequency of melancholic characteristics meeting the criteria of DSM-5 between the group of patients with drug-resistant bipolar depression of the anhedonic type and the other groups of subjects [30 minutes after inclusion]
melancholic characteristics of DSM-5 has 8 items (2 A catory and 6 B category) Presence of melancholic characteristics is defined by a presence of at least one item from A category and the presence of at least 3 items from B category Absence of melancholic characteristics is defined by no item from A category and less than 3 items from B category
- Difference in the Montgomery-Åsberg Depression Rating Scale (MADRS) assessment score for EDC severity between the group of patients with bipolar drug-resistant depression of the anhedonic type and the other groups of subjects [30 minutes after inclusion]
Montgomery-Åsberg Depression Rating Scale (MADRS) 10 items scored from 0 to 6 (6 correspond to maximal severity of the item). The score varies from 0 to 60 (60 = maximal severity of intensity of depression). Total score ≥ 8/60 defines a clinically significant intensity of depression. Total score > 30/60 defines a major intensity of depression
- Difference in the score for evaluation of repetitive negative thinking by the Perseverative Thinking Questionnaire (PTQ) between the group of patients with bipolar drug-resistant [30 minutes after inclusion]
the Perseverative Thinking Questionnaire (PTQ) has 15 items scored from 0 (never) to 5 (almost always = maximum severity of the dimension evaluated by the item). The score varies from 0 (absence of repetitive negative thinking) to 60 (maximum severity of the intensity of repetitive negative thinking)
- Difference in the score for the evaluation of parkinsonian symptoms (classification of Hoehn & Yahr) between the group of patients with bipolar drug-resistant depression of the anhedonic type and the other groups of patients [30 minutes after inclusion]
The score varies from 0 (no sign) to 5 (worse disability)
