Study summary

The goal of this observational study is to evaluate the long-term effect of DBS-STN on cognitive and behavioral outcomes in Parkinson's disease (PD) patients.

PD patients will be assessed over time using tests, questionnaires and standardized clinical scales. An initial assessment (T0) and annual follow-up assessments will be carried out for 5 years.

Researchers will compare data collected from patients with DBS versus patients with best medical therapy.

What researchers measure

Primary outcomes

  1. Long-term characterization of DBS-STN on cognitive outcomes

    Cognitive impairment change from baseline until 5 years in Montreal Cognitive Assessment (MoCA; min. 0, max. 30, higher score means better outcome) \[Time Frame: Annual assessments up to 5 years\]

    Time frame: Annual assessments up to 5 years

  2. Beck Depression Inventory

    Depressive symptoms change from baseline to 5 year (BDI-II, min 0, max 63, higher score means worse outcome)

    Time frame: Annual assessments up to 5 years

  3. State-Trait Anxiety Inventory

    Anxiety symptoms change from baseline to 5 year (STAI, min 20, max 80, higher score means worse outcome)

    Time frame: Annual assessments up to 5 years

  4. Questionnaire for Impulsive-Compulsive Disorders in Parkinson

    Impulsivity change from baseline to 5 years (QUIP, min 0, max 112, higher score means worse outcome)

    Time frame: Annual assessments up to 5 years

  5. Pittsburgh Sleep Quality Index

    Sleep Quality change (PSQI, min 0, max 21, higher score means poorer sleep quality)

    Time frame: Annual assessments up to 5 years

  6. Parkinson's Disease Questionnaire-8

    Quality of life change from baseline to 5 years (PDQ-8, min 0, max 100, higher score means worse outcome)

    Time frame: Annual assessments up to 5 years

  7. Minnesota Multiphasic Personality Inventory 2-RF

    Personality change from baseline to 5 years (MMPI-2-RF, cut-off: T\>65 for clinical scales)

    Time frame: Annual assessments up to 5 years
