2. 1. Deep brain stimulation of the posterior subthalamic area in the treatment of movement disorders

   Author : Anders Fytagoridis; Patric Blomstedt; Joachim Krauss; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Deep brain stimulation; Movement disorders; Posterior subthalamic area; Zona incerta; Prelemniscal radiations; Tremor; Essential tremor; Parkinson s disease; neurokirurgi; Neurosurgery;

   Abstract : Background: The posterior subthalamic area (PSA) is essentially composed of the caudal Zona incerta and the prelemniscal radiation. Subthalamotomy in the PSA was renowned for its effectiveness in alleviating movement disorders and particularly tremor. READ MORE

4. 2. Stereotactic imaging in functional neurosurgery

   Author : Hidehiro Hirabayashi; Patric Blomstedt; Takaomi Taira; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Deep brain stimulation; pallidotomy; thalamotomy; Parkinson s disease; essential tremor; CT; MRI; neurokirurgi; Neurosurgery;

   Abstract : Background: The birth of stereotactic functional neurosurgery in 1947 was to a great extent dependent on the development of ventriculography. The last decades have witnessed a renaissance of functional stereotactic neurosurgery in the treatment of patients with movement disorders. READ MORE

5. 3. Thermocoagulation in Deep Brain Structures : Modelling, simulation and experimental study of radio-frequency lesioning

   Author : Johannes Johansson; Karin Wårdel; Stefan Andersson-Engels; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosurgery; Radiofrequency ablation; Finite element method; Blood perfusion; Cerebrospinal fluid; Free convection; Neurosurgery; Neurokirurgi;

   Abstract : Radio-frequency (RF) lesioning is a method utilising high frequency currents for thermal coagulation of pathological tissue or signal pathways. The current is delivered from an electrode with a temperature sensor, permitting control of the current at a desired target temperature. In the brain RF-lesioning can e.g. READ MORE

6. 4. Deep brain stimulation targeting the caudal zona incerta as a treatment for parkinsonian and essential tremor

   Author : Rasmus Stenmark Persson; Patric Blomstedt; Sara af Bjerkén; Marwan Hariz; Anders Fytagoridis; Alfonso Fasano; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; movement disorders; parkinson s disease; tremor; essential tremor; deep brain stimulation; zona incerta; posterior subthalamic area; Neurology; neurologi; neurokirurgi; Neurosurgery;

   Abstract : Background: Deep brain stimulation (DBS) is used as a treatment for Parkinson’s disease (PD) and Essential tremor (ET) when medications are insufficient. The most common DBS-targets for PD and ET, the subthalamic nucleus (STN) and the ventral intermediate nucleus of the thalamus (Vim) respectively, have certain side effects and limitations. READ MORE

7. 5. Analysis of deep brain stimulation and ablative lesions in surgical treatment of movement disorders : with emphasis on safety aspects

   Author : Patric Blomstedt; Bengt Linderoth; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; deep brain stimulation; pallidotomy; thalamotomy; complications; Parkinson s disease; essential tremor; Clinical Neurophysiology; klinisk neurofysiologi;

   Abstract : Background The last decade has witnessed a renaissance of functional stereotactic neurosurgery in the treatment of patients with movement disorders, especially advanced Parkinson’s disease (PD), essential tremor (ET) and dystonia. Ablative lesions such as thalamotomy and pallidotomy have been gradually replaced by the technique of chronic deep brain stimulation (DBS) applied to targets in the basal ganglia and thalamus, and assumed to be more lenient to the brain than stereotactic radiofrequency lesions.
