Cognitive impairment and dementia pose particular challenges in the management of patients with Parkinson's disease (PD). Decision-making capacity can render patients vulnerable in a way that requires careful ethical considerations by clinicians with respect to medical decision making, research participation, and public safety. Clinicians should discuss how(More)
Oral squamous cell carcinoma has a remarkable incidence worldwide and a fairly onerous prognosis, encouraging further research on factors that might modify disease outcome. In this review article, the authors approach the factors that may exert influence on the prognosis and eventually guide the selection of patients for more aggressive therapies. Published(More)
Parkinson's disease (PD) is one of the most common neurodegenerative disorders. The condition causes a heavy burden both on those affected, as well as their families. Accurate diagnosis is critical and remains founded on clinical grounds as no specific diagnostic test is available so far. The clinical picture of PD is typical in many instances; however,(More)
Background Improving survival and extending the longevity of life for all populations requires timely, robust evidence on local mortality levels and trends. The Global Burden of Disease 2015 Study (GBD 2015) provides a comprehensive assessment of all-cause and cause-specifi c mortality for 249 causes in 195 countries and territories from 1980 to 2015. These(More)
Parkinson's disease is a common and often debilitating disorder, with a growing prevalence accompanying global population aging. Current drug therapy is not satisfactory enough for many patients, especially after a few years of symptom progression. This is mainly due to the motor complications that frequently emerge as disease progresses. Deep brain(More)
Motion processing involves multiple hierarchical steps, from the magnocellular pathway, sensitive to high temporal frequency modulations, to subsequent motion integration within the visual cortical dorsal stream. We have tested whether motion integration deficits in mild Parkinson disease (PD) can be explained by visual deficits in earlier processing nodes.(More)
Progressive myoclonus epilepsies (PMEs) are a group of rare, inherited disorders manifesting with action myoclonus, tonic-clonic seizures and ataxia. We sequenced the exomes of 84 unrelated individuals with PME of unknown cause and molecularly solved 26 cases (31%). Remarkably, a recurrent de novo mutation, c.959G>A (p.Arg320His), in KCNC1 was identified as(More)
INTRODUCTION Deep brain stimulation (DBS) is effective in advanced Parkinson's disease (PD), improving motor symptoms, fluctuations and quality of life. However, adverse psychiatric outcomes have been reported, albeit variably and in an unstandardized fashion. We aimed to summarize the published evidence on the outcomes of anxiety and depressive symptoms in(More)
A 23-year-old man with a clinically isolated syndrome (right optic neuritis) diagnosed 6 months before, presented with recurrent, brief, painful, stereotyped, involuntary posturing movements of the left upper limb. The neurological examination was otherwise unremarkable (except for right optic atrophy). Intravenous methylprednisolone was initiated; the(More)
Tourette syndrome (TS) is a potentially disabling chronic tic disorder often associated with neuropsychiatric comorbidities and typical onset during childhood [1]. Medication frequently causes bothersome adverse effects and deep brain stimulation (DBS) has been tried in severe refractory cases [2]. A 14-year-old boy with several motor and phonic tics(More)
