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

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

    Abstract : 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.

  4. 2. 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

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

    Author : Linda Sandström; Fredrik Karlsson; Patric Blomstedt; Lena Hartelius; Adam Vogel; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. 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

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

    Author : Amar Awad; Johan Eriksson; Patric Blomstedt; Richard Levi; Lars Nyberg; Rick Helmich; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE
