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.
