Who is a candidate for deep brain stimulation?

Introduction to Deep Brain Stimulation

Overview:

  • Definition of Deep Brain Stimulation (DBS).
  • History and development of DBS.
  • General mechanism and how it works.

Conditions Treated:

  • Movement disorders (e.g., Parkinson’s disease, essential tremor, dystonia).
  • Neuropsychiatric conditions (e.g., obsessive-compulsive disorder, depression).
  • Other potential uses (e.g., epilepsy, Tourette syndrome).

Page 2: Parkinson’s Disease

Candidates:

  • Patients with a definitive diagnosis of Parkinson’s disease.
  • Those experiencing motor complications not adequately controlled by medication.
  • Patients with severe tremors, rigidity, or bradykinesia.

Considerations:

  • Optimal candidates are typically those who respond well to levodopa.
  • Age and overall health of the patient.
  • Duration and progression of the disease.

Page 3: Essential Tremor

Candidates:

  • Patients with significant tremors affecting daily activities.
  • Those who do not respond to medications such as beta-blockers or anticonvulsants.

Considerations:

  • The severity and impact of tremors on quality of life.
  • Previous treatments and their effectiveness.
  • Potential risks and benefits of the procedure.

Page 4: Dystonia

Candidates:

  • Patients with primary dystonia (genetic or idiopathic).
  • Secondary dystonia patients after careful evaluation.

Considerations:

  • The type and severity of dystonia.
  • Age of onset and progression of symptoms.
  • Response to previous treatments, including botulinum toxin injections.

Obsessive-Compulsive Disorder (OCD):

  • Patients with severe, treatment-resistant OCD.
  • Comprehensive evaluation by a multidisciplinary team.

Depression:

  • Patients with major depressive disorder who have not responded to multiple treatments.
  • Detailed psychiatric assessment to rule out other conditions.

Page 6: Epilepsy

Candidates:

  • Patients with refractory epilepsy not controlled by medications or other surgical interventions.
  • Specific types of epilepsy (e.g., focal seizures).

Considerations:

  • Detailed seizure mapping and localization.
  • Previous surgical outcomes and potential for improvement.

Page 7: Tourette Syndrome and Other Conditions

Tourette Syndrome:

  • Patients with severe tics impacting daily functioning.
  • Those who have not responded to behavioral therapy and medications.

Other Conditions:

  • Investigational uses for conditions like chronic pain, cluster headaches, and Alzheimer’s disease.
  • Ongoing clinical trials and emerging research.

Page 8: General Candidate Assessment and Contraindications

Evaluation Process:

  • Comprehensive neurological and psychological evaluation.
  • Brain imaging studies (e.g., MRI, CT scans).
  • Assessment by a multidisciplinary team including neurologists, neurosurgeons, and psychiatrists.

Contraindications:

  • Patients with significant cognitive impairment or dementia.
  • Those with uncontrolled psychiatric conditions.
  • Presence of severe comorbidities increasing surgical risk.

Conclusion:

  • Summary of key points.
  • Future directions and potential advancements in DBS.
  • Importance of individualized patient assessment for optimal outcomes.
