  1. 1. Quantitative methods for evaluation of tremor and neuromotor function: Application in workers exposed to neurotoxic metals and patients with essential tremor

    Författare :Gunilla Wastensson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tremor; neuromotor function; neurobehavioral methods; mercury vapor; manganese; previous exposure; welding; essential tremor; deep brain stimulation;

    Sammanfattning : The overall purpose of this thesis was to investigate the usefulness of certain quantitative methods for detecting or quantifying changes in tremor or other neuromotor functions. Tremor and impairment in neuromotor function may be the early signs of adverse effects due to low-level exposure to neurotoxic metals such as mercury and manganese, and are also common features of neurological diseases.

  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. Functional brain imaging of sensorimotor dysfunction and restoration : investigations of discomplete spinal cord injury and deep brain stimulation for essential tremor

    Författare :Amar Awad; Johan Eriksson; Patric Blomstedt; Richard Levi; Lars Nyberg; Rick Helmich; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sensorimotor control; fMRI; discomplete spinal cord injury; essential tremor; deep brain stimulation; cerebello-thalamo-cerebral circuit; Physiology; fysiologi; neurokirurgi; Neurosurgery; Neurology; neurologi; rehabiliteringsmedicin; Rehabilitation Medicine;

    Sammanfattning : The nervous system exists to generate adaptive behaviour by processing sensory input from the body and the environment in order to produce appropriate motor output, and vice versa. Consequently, sensorimotor dysfunction is the basis of disability in most neurological pathologies. LÄS MER

  7. 5. 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
