However, these medications have been shown to have a variable effect on tremors and some individuals experience medication-related side effects which can impact their quality of life (QoL). <\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">Deep Brain Stimulation (DBS) is an innovative treatment used for managing motor symptoms without medication-related side effects. DBS involves placing electrodes in specific areas of the brain to produce electrical impulses that help alleviate symptoms of neurodegenerative diseases such as Parkinson&rsquo;s. To be eligible for DBS treatment, a person needs to have had Parkinson&rsquo;s for over four years and can be benefitting from medication but faces motor complications such as significant \u201coff\u201d periods (when symptoms return because medication isn&rsquo;t working well) and\/or dyskinesia (uncontrolled, involuntary movements).<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">DBS has been commonly used as a second-line treatment for Parkinson&rsquo;s after medication has been tried. More recently, some experts have proposed earlier use of DBS to prevent medication-related side effects altogether. In fact, some trials have shown improved QoL when DBS was implemented prior to the onset of motor symptoms.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">The main challenge of early DBS treatment is that the course of Parkinson&rsquo;s remains unclear and is variable in individuals.

They discovered that the most significant baseline predictors of which Parkinson&rsquo;s patients would undergo DBS surgery in the future were: younger age at symptom onset, less severe initial disease stage, increased presence of tremor at diagnosis, as well as other markers. <\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">This study offers a unique window of opportunity to predict patients earlier on who would be eligible for DBS.
