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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of change of mania symptoms | Baseline, 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
| Measure | Time frame | Description |
|---|---|---|
| Assessment of change of Behavior | Baseline, 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 Impulsivity | Baseline, 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 Apathy | Baseline, 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 change of depressive symptoms | Baseline, 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 executive functions | Baseline, 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. |
| Assessment of confusion | 72 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 personality | Baseline | 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) |
