Who may be evaluated for DBS
DBS candidacy is individualized. A movement-disorders neurologist and functional neurosurgery team usually review the diagnosis, symptom pattern, medication response, cognitive and psychiatric factors and the practical ability to attend programming visits after surgery.
- Confirmed movement-disorder diagnosis
- Symptoms that remain disabling despite optimized medical treatment or cause difficult medication-related complications
- A symptom pattern that is likely to respond to stimulation
- Acceptable surgical and anesthesia risk
- A realistic plan for post-operative programming and follow-up
What the pre-operative work-up can include
The exact evaluation differs by center and diagnosis. University programs commonly combine neurological examination, medication history, imaging and multidisciplinary review before a surgical decision is made.
- Detailed medication and symptom history
- Neurological examination and movement-disorder assessment
- Brain MRI or other imaging when required
- Cognitive or neuropsychological assessment in selected patients
- Neurosurgical consultation and discussion of target selection
- Review of expectations, device management and follow-up needs
How the treatment works
DBS involves implantation of electrodes into defined brain targets. The electrodes are connected to an implanted pulse generator. After surgery, stimulation settings are adjusted over time to balance symptom control and side effects. The precise target and programming strategy depend on the diagnosis and individual symptom profile.
What DBS can and cannot promise
DBS aims to improve selected symptoms and quality of life; it does not cure the underlying neurodegenerative disease. Medication may still be required, and some symptoms respond better than others. The likely benefit should be discussed before surgery using the patient’s own symptom profile rather than generic outcome claims.
What an international patient should prepare
For a meaningful remote review, prepare a concise neurological summary and records that show the course of the disease and response to previous treatment.
- Current neurological diagnosis and date of diagnosis
- Medication list with doses and previous medication trials
- Description of the most disabling symptoms and fluctuations
- Recent brain imaging if available
- Previous neurological or neuropsychological assessments
- Any prior device or surgical treatment
- A specific question: candidacy review, second opinion or surgery planning
