  1. 1. Stereotactic functional procedures in the treatment of essential tremor

    Författare :Ulrika Sandvik; Patric Blomstedt; Lars-Owe Koskinen; Stig Rehncrona; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Essential Tremor; Stereotactic Functional Neurosurgery; Deep Brain Stimulation; Posterior Subthalamic Area; Thalamotomy; Zona incerta; caudal Zona incerta; Quality of Life; Vim; neurokirurgi; Neurosurgery;

    Sammanfattning : Background: Essential tremor (ET) is the most common movement disorder. In cases resistant to pharmacological treatment, functional stereotactic neurosurgery can be an alternative. Lesional surgery has largely been replaced by deep brain stimulation (DBS). The current target of choice is the ventrolateral thalamus (Vim). LÄS MER

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

    Författare :Rasmus Stenmark Persson; Patric Blomstedt; Sara af Bjerkén; Marwan Hariz; Anders Fytagoridis; Alfonso Fasano; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Impact of deep brain stimulation in the caudal zona incerta on voice tremor and speech in persons with essential tremor

    Författare :Linda Sandström; Fredrik Karlsson; Patric Blomstedt; Lena Hartelius; Adam Vogel; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caudal zona incerta; deep brain stimulation; essential tremor; speech function; speech intelligibility; speech production; voice tremor;

    Sammanfattning : Objectives: Deep brain stimulation (DBS) is a symptomatic treatment for people with essential tremor (ET) who have unsatisfactory tremor relief with pharmacological treatment alone. A common symptom of ET is voice tremor, but only about 50% of patients with voice tremor get a satisfactory result with DBS. LÄS MER

  5. 4. Cognitive effects of deep brain stimulation : focus on caudal zona incerta for essential tremor and Parkinson´s disease, and on bed nucleus of stria terminalis for obsessive compulsive disorder

    Författare :Johanna Philipson; Patric Blomstedt; Marjan Jahanshahi; Marwan Hariz; Jean-Luc Houéto; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Deep brain stimulation. Neuropsychology. Cognition. Parkinson’s disease. Essential tremor. Obsessive-compulsive disorder. Caudal zona incerta. Bed nucleus of stria terminalis. Functional MRI.; Neurology; neurologi;

    Sammanfattning : Preserved cognition is an important determinant for perceived Quality of Life (QoL) and has been found to be essential in order to translate improvements in primary symptoms following Deep Brain Stimulation (DBS) into activities of daily living that drive QoL. Therefore, it is important to evaluate not only the clinical improvement, but also the cognitive impact of DBS. LÄS MER

  7. 5. Deep brain stimulation of the posterior subthalamic area in the treatment of movement disorders

    Författare :Anders Fytagoridis; Patric Blomstedt; Joachim Krauss; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
