New Dystonia Paper in Science Translational Medicine

Link to paper Abstract: Dystonias are a group of chronic movement–disabling disorders for which highly effective oral medications or disease-modifying therapies are lacking. The most effective treatments require invasive procedures such as deep brain stimulation. In this study, we used … Continue reading

Cell-specific effects of a Dyt1 knock-out model

Abstract Pubmed Link DYT1 dystonia is a debilitating movement disorder characterized by repetitive, unintentional movements and postures. The disorder has been linked to mutation of the TOR1A/DYT1 gene encoding torsinA. Convergent evidence from studies in humans and animal models suggest … Continue reading

New study on DBS in Essential Tremor

https://www.ncbi.nlm.nih.gov/pubmed/31794958 OBJECTIVE:  Essential tremor (ET) prominently affects the upper-limbs during voluntary movements, but can also affect the lower-limbs, head, and chin. Although deep brain stimulation (DBS) of the ventral intermediate nucleus (VIM) of thalamus improves both clinical ratings and quantitative … Continue reading

Beta Band EEG Relates to Putamen fMRI in Parkinson

Download Paper Abstract We investigated the effect of acute levodopa administration on movement-related cortical oscillations and movement velocity in Parkinson’s disease (PD). Patients with PD on and off medication and age- and sex-matched healthy controls performed a ballistic upper limb … Continue reading
