1. DEEP BRAIN STIMULATION DR SHALOM NWACHUKWU

2. What is dbs? Elective surgical procedure to implant a device that sends electrical signals to brain areas responsible for body movement. Used in treatment of movement and psychiatric disorders

3. History of deep brain stimulation

4. Who is a candidate? Deep brain stimulation can be used to treat a range of movement disorders refractory to (or complicated by) pharmacological therapy. It includes conditions such as: a movement disorder with worsening symptoms (tremor, stiffness) and your medications have begun to lose effectiveness. troubling "off" periods when your medication wears off before the next dose can be taken. troubling "on" periods when you develop medication-induced dyskinesias (excessive wiggling of the torso, head, and/or limbs).

5. The DBS system involves three distinct components:

6. Testing & Diagnosis Blood and urine tests MRI/CT SCAN MEDICAL CLEARANCE

7. Step 1: attach stereotactic frame Step 2 MRI or CT scan Step 3 skin and skull incision Step 4 insert electrode in the brain Step 5 stimulate the brain cells and closure PROCEDURE

8. Advantages and complications Advantages - Can be performed on one or both sides of the brain, depending on symptoms. - The effects are reversible and can be customized individually for each patient’s clinical status. -Stimulation settings can be modified to diminish potential side effects and improve effectiveness over time. -The device can provide continuous symptom control 24 hours a day. -Patients who have undergone DBS can participate in other treatments, such as stem cell or gene therapy, when they become available. Complications - Operation-related complications: perioperative intracranial haemorrhage and electrode malposition. - Hardware-related complications include electrode migration, electrode fracture, and infection and erosion - Stimulation-related complications include sensorimotor conditions including dyskinesia and blepharospasm, transient confusion, mood changes, or even psychiatric conditions, such as manic episodes
