Objective: Minimally-invasive intracranial drain placement is a common neurosurgical emergency procedure in patients with intracerebral hemorrhage (ICH). We aimed to retrospectively investigate the accuracy of conventional (bedside) hemorrhage drain placement and to prospectively compare the accuracy [for full text, please go to the a.m. URL]

Objective: To evaluate safety and efficacy of disconnection of epileptogenic hypothalamic hamartomas with stereotactic radiofrequency thermocoagulation (SRT). Methods: Between 07/2015 and 11/2020 we treated 30 consecutive patients (9 female, 21 male) with epileptogenic hypothalamic hamartomas[for full text, please go to the a.m. URL], 72.

Objective: For our youngest pediatric patients the use of a stereotactic frame is still controversial. In a retrospective study we analyzed the medical records of these patients. Methods: Since 1990 a total of 928 children (mean age 9.89 years) underwent 1650 frame based stereotactic procedures,[for full text, please go to the a.m. URL], 70.

For more than 15 years deep brain stimulation of the subthalamic nucleus and globus pallidus internus have become therapeutic options in advanced Parkinson's disease. The number of patients with long-term treatment is increasing steadily. This review focuses on issues of the long-term care of these Parkinson's patients, including differences of the available deep brain stimulation systems, recommendations for follow-up examinations, implications for medical diagnostics and therapies and an algorithm for symptom deterioration. Today, there is no profound evidence that deep brain stimulation prevents disease progression. However, symptomatic relief from motor symptoms is maintained during long-term follow-up and interruption of the therapy remains an exception.

Camptocormia is recognised as a severe postural movement disorder complicating neurodegenerative diseases like Parkinson's disease (PD) and multisystem atrophy. Pathophysiologically two main hypotheses are discussed: (i) a disorder of the basal ganglia resulting in axial dystonia and rigidity on the one hand and (ii) an extensor truncal myopathy on the other hand. Therapeutic efforts often result in limited success. Therefore, reports on improvements by deep brain stimulation (DBS) are of great interest. However, the role of DBS in the treatment of camptocormia remains unclear. Here, we report a female PD patient who responded well to DBS of the subthalamic nucleus for severe dyskinesias and fluctuations. However, after 6 months she started to develop a rapidly progressing camptocormia which did not respond to DBS. The clinical and electrophysiological examination suggested a truncal erector myopathy. The inconsistent reports on the effects of DBS on camptocormia in PD patients suggest heterogeneous pathogenetic pathways. A pathophysiological subtype with predominant basal ganglia dysfunction and responsivity to DBS, however, seems to be rather rare. A myopathy, in contrast, seems to be more frequent and DBS is not effective in this condition. Therefore, camptocormia in PD patients is not an established indication for DBS.

Objective: An inquiry among 16 patients treated with bilateral thalamic (Vim: Nucleus ventralis intermedius thalami) deep brain stimulation (DBS) for essential tremor revealed that the majority (10/16) suffered from stimulation induced taste disturbances.

Objective: The amount of resection is closely related to survival in brain tumours. To enhance resection, especially intraoperative magnetic resonance imaging (MRI) has been applied. The aim of this prospective, randomized study was to test if intraoperative 3-D ultrasound likewise can be used for resection[for full text, please go to the a.m. URL], 62.

Objective: A 69-year-old patient with successful reduction of his disabling upper extremity essential tremor experienced an almost complete but during stimulation cessation reversible ageusia under bilateral thalamic ventral intermediate nucleus (VIM) deep brain stimulation (DBS).
