Posterior hypothalamic-deep brain stimulation (pHyp-DBS) has been reported as a successful treatment for reducing refractory aggressive behaviors in patients with distinct primary diagnoses. Here, we report on a patient with cri du chat syndrome presenting severe self-injury and aggressive behaviors toward others, who was treated with pHyp-DBS. Positive results were observed at long-term follow-up

Aligning Dentato-Rubro-Thalamic Tract and Subthalamic Nucleus Targets in a Patient with Comorbid Essential Tremor and Parkinson’s Disease: Case Report Stereotact. Funct. Heurosurg. (IF 1.7) Pub Date : 2022-11-29 Alexandra Boogers, Tine Van Bogaert, Jana Peeters, Ugur Kilic, Stefan Sunaert, Wim Vandenberghe, Myles Mc Laughlin, Philippe De Vloo, Bart Nuttin
Deep brain stimulation is an established treatment option for both essential tremor (ET) and Parkinson’s disease (PD), although typically targeting different brain structures. Some patients are diagnosed with comorbid ET and PD. Selecting the optimal stimulation target in these patients is challenging. We present a patient with comorbid ET and PD in whom we used bilaterally a single parietal trajectory

MRI Changes in Failed Radiosurgery for Vestibular Schwannomas Stereotact. Funct. Heurosurg. (IF 1.7) Pub Date : 2022-11-10 Nicolas Massager, Cecile Renier
Introduction: Radiosurgery is now a recognized treatment of vestibular schwannoma (VS); however, radiosurgical irradiation sometimes fails to stop tumor growth in the long term. Some changes in MR imaging after radiosurgery that are supposed to be related to permanent tumor control may be observed in patients with failed treatment. The objective of the present study was to evaluate the MRI changes

Cerebellar Cortex Stimulation for Acquired Dystonia: A Case Report and Review of Its Role in Modern Surgical Practice Stereotact. Funct. Heurosurg. (IF 1.7) Pub Date : 2022-09-12 Anna Stroud, Stephen Tisch, Benjamin P. Jonker
Background: Cerebral palsy (CP) is a common cause of acquired dystonia, which can lead to significant interference with quality of life and societal participation. In the last two decades, the surgical treatment of dystonia has primarily focused on deep brain stimulation targeting the basal ganglia and thalamic circuits. However, stimulation of the basal ganglia has generally been less effective in
