Tremor is an involuntary rhythmic muscle movement assessed subjectively by specialists. To improve accuracy and mitigate bias, tremor must be video recorded and rated by multiple experts. Existing video-based motion tracking techniques can be applied

The aim of the present study was to assess the effects of dopaminergic medication on the selection-for-action mechanisms in Parkinson's disease (PD). PD subjects were tested after not having taken medication for at least 12 h ("Off' state) and then r

Patients with intractable tremor not alleviated by pharmaceutical therapies can be successfully treated using Deep Brain Stimulation of subcortical areas such as the Subthalamic Nucleus (STN). Current DBS devices produce constant-current or constant-

This report details the emergence of a progressive parkinsonian syndrome, dementia and behavioural disturbance in a 33 year-old woman which can be dated to the delivery of her first child. The findings of this case indicate that cortical Lewy body di

Data regarding the effect of deep brain stimulation (DBS) surgery on the dopamine dysregulation syndrome (DDS), impulse control disorders (ICDs) and punding in Parkinson’s disease (PD) are limited. We present a case series of 21 operated PD patient

Deep brain stimulation (DBS) is used to alleviate tremor in patients diagnosed with Essential Tremor who do not respond to conventional treatments. To achieve optimal tremor suppression, a large stimulus parameter space needs to be explored. In pract

Although some motor functions of the basal ganglia have been well studied, the oculomotor functions are not well established. We studied eye movements in patients with Parkinson's disease (PD) undergoing pallidotomy to assess the role of the globus p

Whilst pallidotomy is emerging as a popular approach to the treatment to Parkinson’s disease, little is yet known about the cognitive effects of this procedure. This study presents 19 patients (6 right, 13 left) who were assessed both before and af
