BACKGROUND AND PURPOSE Several studies have reported that diffusion-weighted imaging (DWI) is able to help discriminate a Parkinson variant of multiple system atrophy (MSA-p) from Parkinson's disease (PD) on the basis of the increased regional apparent diffusion coefficient (rADC). We analyzed the usefulness of DWI by using the rADC for differential(More)
Parkinson's disease (PD) can be divided into the akinetic-rigid (ART), mixed (MT), and tremor-dominant (TDT) subtypes according to the clinically dominant symptoms. We analyzed the correlations between (123)I-meta-iodobenzylguanidine (MIBG) uptake and the clinical features of patients with various PD subtypes. In addition, we evaluated the relationship(More)

Although several placebo-controlled trials have documented the clinical efficacy and safety of frovatriptan in adults with migraine, this drug has not previously been studied in Asian including Korean patients.

PURPOSE To analyze the characteristics of neuropsychological profiles and gray matter volume in de novo, drug-naïve Parkinson's disease with mild cognitive impairment (PD-MCI). METHODS Fifty-two newly diagnosed PD patients were assessed with neuropsychological testing, and PD-MCI was defined in patients with at least one or more abnormal cognitive test(More)
Extrapyramidal signs are neurological dysfunction commonly associated with Wilson's disease (WD). In addition, cognitive dysfunction has been reported in the early stages of WD. In this report, we describe a 49-year-old woman presenting with memory impairments and without Parkinsonian or extrapyramidal signs. She was diagnosed with WD based on the presence(More)
BACKGROUND AND PURPOSE Although peripheral trauma induced movement disorders have been rarely reported, diagnostic criteria for peripherally induced movement disorders (PIMD) have been established. Because preexisting subclinical movement disorders, or secondary gain for compensation and legal purposes are difficult to confirm, differential diagnosis for(More)
