Deep brain stimulation for Parkinson's Disease may cause aggressive behavior. Adjusting stimulation intensity is crucial for managing emotional side effects and improving patient quality of life.

Area of Science:

  • Neuroscience
  • Neurosurgery
  • Psychiatry

Background:

  • Parkinson's Disease (PD) is a progressive neurodegenerative disorder.
  • Bilateral subthalamic nucleus deep brain stimulation (DBS) is an established treatment for PD.
  • DBS involves surgically implanting electrodes to modulate abnormal brain activity.

Observation:

  • A patient with PD experienced new-onset aggressive behavior disorder after DBS surgery.
  • Symptoms included disturbed impulse control and difficulty managing anger.
  • These behavioral changes emerged after the "switch-on" of the DBS device.

Findings:

  • The aggressive behavior is hypothesized to be related to the "switch-on" stimulation intensity.
  • Increased voltage may affect adjacent limbic system pathways involved in emotional regulation.

  • Subthalamic nucleus DBS may have unintended effects on affect and emotional behavior.

    • Implications:

    • Neuropsychological disturbances should be evaluated in patients undergoing DBS for PD.
    • The intensity of DBS stimulation may require careful titration to balance motor and behavioral outcomes.
    • Further research is needed to understand the relationship between DBS parameters and emotional regulation in PD patients.
