Background: Deep brain stimulation (DBS) of the bilateral subthalamic nuclei (STN) or globus pallidus internus (GPi) for Parkinson's disease (PD) and dystonia is known for its efficacy despite potential complications. Although acute complications such as intracranial hemorrhage and infections are documented, delayed occurrences like normal pressure hydrocephalus (NPH) post-DBS has not been reported so far.
Cases: We present a case series of seven PD patients (from 974) who developed NPH, an average of 10.
