Evidence-based approaches to managing this condition.
First-line treatments
Advanced neuroimaging surveillance
Regular MRI and functional imaging to monitor structural changes in the subthalamic nucleus and assess disease progression or treatment response.
Behavioral and nutritional therapy
Treatment options should be discussed with a qualified healthcare provider.
Deep brain stimulation surgery
High-frequency electrical stimulation of the subthalamic nucleus to reduce hyperdirect pathway activity and normalize motor circuit function in movement disorders.
Additional treatment options
Antiparkinsonian medication adjustment
Optimization of dopaminergic therapy based on symptom response and motor complications, potentially reducing medication needs post-DBS.
