..However, their use is limited by actual and perceived adverse events (AE). To our knowledge, no study has evaluated for predictors of these problems...

..This supports segregation between task-specific tremor and essential tremor but does not support the specific diagnosis of "writing tremor" because many patients progress to tremor with other tasks...

..Falls lessened with activation in ET patients. Motor control testing was not changed. Bilateral Vim DBS activation mostly improved balance, but may modestly worsen other specific features...

..The medication was well tolerated. The most common adverse event on drug was a sense of "light-headedness" or "dizziness." GABA antagonists represent a novel potential treatment class for PD...

..This may be partially due to a selection bias, but it may also indicate that prior pallidotomy is a negative predictor of outcome of STN DBS and should be considered in patient selection...

..Although the VIM DBS improved tremor, none of the subjects felt there was any meaningful effect on their RLS symptoms. The VIM thalamus, which is involved in ET and Parkinson's disease, does not seem to be primarily involved in RLS...

..The aetiology of EDS is probably multifactorial but is probably exacerbated by dopaminergic medications. Modafinil is a wake-promoting agent approved for use in narcolepsy, but it is often used to treat a variety of somnolent conditions...

..Furthermore, some patients have adapted this simple eye closing strategy when writing, especially signatures...

..It additionally suggests phenotypic overlap between PD and ET...

..All patients who remain on methadone report at least a 75% reduction in symptoms, and none have developed augmentation. Methadone should be considered in RLS patients with an unsatisfactory dopaminergic response...

..05). Total motor Unified Parkinson's Disease Rating Scale scores modestly improved (P < 0.05). There were no adverse events. Mechanisms by which flumazenil could improve PD are discussed...

..Because treatment is so dependent on the underlying etiology, this article mostly concerns diagnosis and provides descriptive case studies...

..TBZ was well tolerated and resulted in a significant improvement in modified AIMS scores in HD patients. These results support the use of TBZ for chorea in patients with HD...

..Restless legs syndrome (RLS) and Parkinson disease (PD) are common neurological conditions that respond to dopaminergic therapy. To our knowledge, the relationship between the two has not been thoroughly explored...

..We conclude that VIM DBS may mildly improve ipsilateral ET, and that concerns about meaningful ipsilateral tremor augmentation after device deactivation are not warranted...

..PD is associated with a variety of sleep problems. The dopamine agonists (DA) pramipexole and ropinirole were recently implicated in causing "sleep attacks" and motor vehicle accidents...

..There are, however, relatively little data concerning bilateral thalamic DBS and no thorough comparisons between the 2 methods...

..To assess hearing in patients with essential tremor (ET) vs patients with Parkinson disease (PD) and normal controls...

..26 +/- 19 (P < 0.05). BTX may help chronic daily headache and appears to have a cumulative effect with subsequent injections. The treatment was very well tolerated...

..Despite the high concordance rate, the disease severity, age at onset, and symptom descriptions often varied between twins. Birth order, birth weight, and serum ferritin levels did not predict RLS severity or age at onset...

..Based on the relatively high rates of dry mouth seen with botulinum toxin B, there is reason to suspect that it may also improve sialorrhea...

..Progressive supranuclear palsy (PSP) is a neurodegenerative disorder that is frequently mistaken for Parkinson's disease (PD) in its early stages...

..Augmentation-an increase in the duration, intensity, and anatomy of RLS symptoms-is commonly associated with dopaminergic treatments; however, risk factors for this troubling scenario have not been formally evaluated...

..Tetrabenazine, a monoamine depleter and dopamine receptor blocker, is used to treat several hyperkinetic movement disorders. The authors studied the use of tetrabenazine for tardive dyskinesia...

..The frequency and amplitude of the episodes initially markedly improved after the addition of carbamazepine. We suggest that the movements seen in this case of SSPE may represent basal ganglia ictal activity...

..Ambulatory monitoring of gait objectively measures the dynamic locomotor response to levodopa, and this information could be used to improve daily management of motor fluctuations...

..Rasagiline was well tolerated, with 11.3% of patients (45/398) withdrawing because of an adverse event. Rasagiline therapy for PD was effective, well tolerated, and safe in this long-term trial...

..8%) of all patients exposed to drug (including those originally randomly assigned to placebo) remained on olanzapine. In patients with PD, low-dose olanzapine did not significantly improve hallucinations but did worsen motor function...

..In this study, we compare our results using thalamotomy and pallidotomy to treat patients with different forms of dystonia, and we discuss our results in the context of other published series...

..It is postulated that one type of postural tremor in Parkinson's disease represents a rest tremor that re-emerges after a variable delay while maintaining posture, hence "re-emergent tremor"...
