We report a patient with advanced Parkinson's disease, including severe and frequent off periods with freezing of gait, moderate dysphonia, and some cognitive impairment, who underwent bilateral subthalamic nucleus (STN) stimulation. The patient was followed for 1 year after surgery, showing persistent good mobility without off periods and without freezing,(More)
Deep brain stimulation (DBS) of the nucleus ventralis intermedius thalami (Vim) in the treatment of essential tremor (ET) is well documented concerning the acute effects. Reports of the long-term effects are, however, few and the aim of the present study was to analyse the long-term efficacy of this treatment. Nineteen patients operated with unilateral(More)
Deep brain stimulation (DBS) is an established treatment for essential tremor (ET). The nucleus ventralis intermedius thalami (Vim) is the target of choice, but promising results have been presented regarding DBS in the posterior subthalamic area (PSA). The aim of this study was to evaluate the possible influence of gender, age and severity of disease on(More)
PURPOSE Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has been the mainstream surgical procedure for advanced Parkinson's disease (PD) during the last decade. Reports from a few individual centres have hinted that women who receive STN DBS are under-represented. We aimed to evaluate the gender distribution of patients with PD who had(More)
Walking difficulties are common in neurological and other disorders, as well as among the elderly. There is a need for reliable and valid instruments for measuring walking difficulties in everyday life since existing gait tests are clinician rated and focus on situation specific capacity. The Walk-12G was adapted from the 12-item multiple sclerosis walking(More)
BACKGROUND Deep brain stimulation (DBS) is an established treatment for patients with advanced parkinson's disease (PD). Research shows that women are under-represented among patients undergoing DBS surgery. This may be due to gender-biased selection of patients, but patients' wishes and attitudes may also contribute. This study investigated the decision(More)
OBJECTIVES To report long-term effects of thalamic deep brain stimulation (DBS) on activities of daily living (ADL) and health-related quality of life (HRQoL) in patients with essential tremor (ET). MATERIALS AND METHODS Nineteen consecutive patients were evaluated at baseline, at a mean of 1 year, then at a mean of 7 years after DBS using Tremor Rating(More)
Fifty-eight patients, 36 with essential tremor (ET) and 22 with Parkinson's disease (PD), received deep brain stimulation (DBS) in the thalamic ventral intermediate (Vim) nucleus. The mean follow-up was 17 months for ET and 21 months for PD patients. Stimulation parameters were adjusted as needed, at various intervals after surgery. Results were assessed(More)
OBJECTIVES To evaluate the impact of thalamic deep brain stimulation (DBS) on disability and health-related quality of life in patients with essential tremor. METHODS Twenty seven consecutive patients were evaluated prospectively, before surgery and at a mean of 12 months (range 6-26) after thalamic DBS. Assessment tools included the Fahn-Tolosa-Marìn(More)
Chronic thalamic stimulation (CTS) has a documented good effect on tremor in patients with Parkinson's disease (PD) and essential tremor (ET). This study evaluates whether the alleviation of impairment, i.e., tremor, translates into improvement of the patient's ability in performing instrumental activities of daily living (IADL). Thirteen patients were(More)
