Registration Number
NCT06389903
Lead Sponsor
Centre Hospitalier du Rouvray
Brief Summary

This is a pilot, prospective, monocentric study concerning 15 Parkinson's disease patients requiring deep brain stimulation implantation.

The primary objective is to evaluate the psychiatric lesion effects of deep brain stimulation in patients with Parkinson's disease, using the Young Mania Rating Scale (YMRS), Big Five Inventory and the Hamilton Depression Rating Scale (HAMD 21).

Detailed Description

The patients included were adults suffering from Parkinson's disease (according to ICD-10). They had no severe psychiatric disorders, and no major neurocognitive disorders contraindicating surgery. An initial evaluation will be carried out 72 hours after surgery, then after one month, and finally 3 months after surgery.

Primary Outcome Measures
NameTimeMethod
Assessment of change of mania symptomsBaseline, 72 hours, 1 month and 3 months after surgery

The variation of Young Mania Rating Scale (YMRS). The YMRS total score ranges from 0 to 60 where higher scores indicate more severe mania.

Secondary Outcome Measures
NameTimeMethod
Assessment of confusion72 hours and 3 months after surgery

Confusion Assessment method (CAM). The CAM instrument assesses the presence, severity, and fluctuation of 9 delirium features: acute onset, inattention, disorganized thinking, altered level of consciousness, disorientation, memory impairment, perceptual disturbances, psychomotor agitation or retardation, and altered sleep-wake cycle.

Assessment of change of depressive symptomsBaseline, 72 hours, 1 month and 3 months after surgery

The variation of Hamilton Rating Scale for Depression (HAMD-21). HAMD21 is a 21-item assessment used to measure depression severity. Items were rated on a scale from 0 (symptoms not present) to a maximum of 2 to 4 (symptom extremely severe) for a total score ranging from 0 (not at all depressed) to 64 (severely depressed).

Assessment of change of ImpulsivityBaseline, 72 hours, 1 month and 3 months after surgery

The variation of the Dickman Impulsivity Inventory. It is a self report measure assessing dysfunctional impulsivity and functional impulsivity. Regarding dysfunctional impulsivity (12 items), higher score mean worse adaptation. Regarding functional impulsivity (11 items), higher score mean better adaptation.

Assessment of change of BehaviorBaseline, 72 hours, 1 month and 3 months after surgery

The variation of the Ardouin Scale of Behavior in Parkinson's Disease. The total score ranges from 0 to 84. Higher score mean worse outcome.

Assessment of change of ApathyBaseline, 72 hours, 1 month and 3 months after surgery

The variation of the Apathy Evaluation Scale. This 18 item scale ranges from 0 to 12. Higher score means worse outcome.

Assessment of personalityBaseline

Big Five inventory. The test identified five factors as follows :

* openness to experience (inventive/curious vs. consistent/cautious)

* conscientiousness (efficient/organized vs. extravagant/careless)

* extraversion (outgoing/energetic vs. solitary/reserved)

* agreeableness (friendly/compassionate vs. critical/judgmental)

* neuroticism (sensitive/nervous vs. resilient/confident)

Assessment of executive functionsBaseline, 72 hours, 3 months after surgery

Frontal Assessment Battery at Bedside. Thebattery consists of six subtests exploring the following: conceptualization, mental flexibility, motor programming, sensitivity to interference, inhibitory control, and environmental autonomy.
