Relieve symptoms of neurological disorders

Functional neurosurgery, performed by Dr. George Kakoulides, is a specialized approach to treating neurological conditions like Parkinson’s disease, essential tremor, epilepsy, and chronic pain when medications are no longer effective. By targeting dysfunctional brain or nerves, this surgical field helps restore quality of life and improve function for patients with complex neurological disorders.

Functional neurosurgery is a subspecialty that focuses on improving or restoring neurological function rather than just removing tumors or repairing injuries. It targets specific areas of the brain, spinal cord, or peripheral nerves responsible for abnormal electrical activity causing symptoms such as tremors, stiffness, or chronic pain. This approach is often used when medications fail to provide adequate relief. The goal is to alleviate symptoms and enhance overall quality of life for individuals with movement and neuropsychiatric disorders.

When is functional neurosurgery needed?

Functional neurosurgery is typically recommended when neurological symptoms persist despite conservative treatments like medication, physical therapy, or injections. It becomes necessary when conditions such as movement disorders, chronic pain, or severe spasticity interfere with daily life and cannot be effectively managed through non-surgical means.

You may need functional neurosurgery if conservative treatments fail to treat these conditions:

  • Parkinson’s disease (PD)
  • Essential tremor (ET)
  • Dystonia
  • Tourette syndrome & tic disorders
  • Chronic neuropathic pain
  • Epilepsy (selected cases)
  • Spasticity
  • Obsessive-compulsive disorder (OCD) (selected cases

What are the benefits of functional neurosurgery?

  • Provides relief when medications and therapies fail
  • Targets the source of abnormal brain or nerve activity
  • Improves motor control and reduces involuntary movements
  • Offers long-term symptom management for chronic conditions
  • Enhances overall quality of life and daily functioning
  • Minimally invasive options available for select procedures
  • Customizable treatment plans based on individual needs
  • May reduce the need for long-term medication use

The techniques used during functional neurosurgery

Deep Brain Stimulation (DBS)

Deep Brain Stimulation (DBS) involves implanting electrodes into areas of the brain that control movement or behavior. These electrodes deliver electrical impulses that regulate abnormal brain signals. DBS is widely used for Parkinson’s disease, essential tremor, dystonia, and in some cases, obsessive-compulsive disorder (OCD) and epilepsy.

MR-guided Focused Ultrasound (MRgFUS)

MRgFUS is a non-invasive treatment that uses focused ultrasound waves to create precise lesions in targeted brain tissue. Guided by real-time MRI, this technique treats conditions like essential tremor and Parkinson’s tremor without incisions or implants. It offers fast recovery and minimal risk, making it a powerful alternative to traditional surgery in select patients.

Vagus Nerve Stimulation (VNS)

Vagus Nerve Stimulation (VNS) involves implanting a device under the skin of the chest to send electrical signals to the vagus nerve in the neck. This stimulation helps regulate brain activity and is primarily used for patients with drug-resistant epilepsy or severe depression. It can reduce seizure frequency and improve mood and alertness over time.

Spinal Cord Stimulation (SCS)

Spinal Cord Stimulation (SCS) uses implanted electrodes along the spinal cord to deliver mild electrical pulses that interfere with pain signals before they reach the brain. It is commonly used to manage chronic neuropathic pain or complex regional pain syndrome (CRPS). Patients can adjust the stimulation level using an external device.

Intrathecal Baclofen Pump Placement

This technique involves surgically placing a small pump under the skin to deliver baclofen, a muscle relaxant, directly into the spinal fluid. It is used to manage severe spasticity caused by conditions like multiple sclerosis, spinal cord injury, or cerebral palsy. This method provides more effective relief with fewer side effects than oral medications.

Selective Dorsal Rhizotomy (SDR)

Selective Dorsal Rhizotomy (SDR) is a surgical procedure that targets and selectively severs overactive sensory nerve rootlets in the spine that cause spasticity. It is primarily performed in children with cerebral palsy but may also benefit adults. The goal is to improve muscle tone, mobility, and overall function, often as part of a comprehensive rehabilitation plan.

Lesioning Procedures

Lesioning procedures involve creating small, targeted areas of damage in the brain to disrupt abnormal electrical circuits. Thalamotomy is typically used to control tremors, while pallidotomy helps with rigidity and dyskinesia in Parkinson’s disease. Though less commonly performed today due to advancements in DBS, these techniques remain effective for select cases.

Functional Neurosurgery FAQs

How Do I Know If I Am A Candidate For Functional Neurosurgery?

Candidacy is determined through a comprehensive evaluation with Dr. Kakoulides, which includes a thorough review of your medical history, prior treatments, diagnostic imaging, and current neurological function. Generally, functional neurosurgery is considered when a diagnosed neurological condition has not responded adequately to medication or other conservative therapies. Dr. Kakoulides takes a patient-centered approach and will only recommend surgery when it represents the most appropriate and beneficial path forward for your specific situation.

Are The Effects Of Functional Neurosurgery Permanent?

The durability of results depends on the specific procedure and the condition being treated. Some techniques, such as DBS, are adjustable and reversible, giving both the patient and provider the flexibility to modify the treatment over time as needs evolve. Others, such as lesioning procedures, produce permanent changes to targeted tissue. Dr. Kakoulides will discuss the expected longevity and adjustability of any recommended approach during your consultation.

Will I Still Need Medication After Functional Neurosurgery?

In many cases, functional neurosurgery can significantly reduce a patient’s reliance on medication, though it does not always eliminate it entirely. For conditions like Parkinson’s disease or epilepsy, surgery may allow for lower dosages with fewer side effects, improving overall quality of life. Your care plan will be tailored to your individual needs, and Dr. Kakoulides will work closely with your broader medical team to coordinate the most effective long-term management strategy.

How Long Does Recovery From Functional Neurosurgery Take?

Recovery varies considerably depending on the type of procedure performed. Minimally invasive or non-invasive approaches such as MRgFUS typically involve very little downtime, while more involved procedures like DBS implantation or SDR may require a longer recovery period and rehabilitation. Dr. Kakoulides will provide a personalized recovery timeline and outline what to expect at each stage of the healing process during your consultation.

Is Functional Neurosurgery Available For Pediatric Patients?

Yes, certain functional neurosurgery procedures are appropriate for younger patients. Selective Dorsal Rhizotomy, for example, is primarily performed in children with cerebral palsy to improve muscle tone and mobility. Dr. Kakoulides evaluates each patient individually, and candidacy for pediatric cases is determined based on the specific condition, its severity, and the overall health and developmental profile of the child.
