Medication remains the primary method of treating Parkinson’s disease (PD). However, neuromodulation, or therapies that involve the manipulation of brain circuitry, can also be very effective in controlling PD symptoms in particular clinical situations.
Two current neuromodulatory techniques for PD are deep brain stimulation (DBS) and high intensity focused ultrasound (HIFU). DBS requires the implantation of a wire deep into the brain which stimulates the abnormal circuitry with electricity. HIFU requires the directing of focused ultrasound waves on a small area of the brain to create a lesion.
