The study’s objective was to develop diagnostic predictive models using data from two commonly used [123I]FP-CIT SPECT assessment methods: region-of-interest (ROI) analysis and whole-brain voxel-based analysis. We included retrospectively 80 patients with vascular parkinsonism (VP) and 164 patients with Parkinson’s disease (PD) who underwent [123I]FP-CIT(More)
OBJECTIVES To analyse the differences in the clinical features and characteristics of (123)I-labelled 2β-carbomethoxy-3β-(4-iodophenyl)-N-(3-fluoropropyl) nortropane ((123)I-FP-CIT) single photon emission CT (SPECT) imaging among patients with vascular parkinsonism (VP) and Parkinson's disease (PD). METHODS We performed a case-control study to compare(More)
BACKGROUND Recent studies have shown altered cortical plasticity in adult patients with Tourette syndrome. However, the clinical significance of this finding remains elusive. METHODS Motor cortical plasticity was evaluated in 15 adult patients with severe Tourette syndrome and 16 healthy controls using the paired associative stimulation protocol by(More)
Drooling is a common symptom in parkinsonian disorders. Our aim was to assess the safety and effect of botulinum toxin when applied to parotid glands without ultrasound guidance for sialorrhea in parkinsonian disorders in a retrospective study with a long-term follow-up. We evaluated 53 patients (64.2 % male and 35.8 % female) with a mean age of 70.18 ±(More)
INTRODUCTION Uric acid is a natural antioxidant, and it has been shown that low levels of uric acid could be a risk factor for the development of PD. Our aim was to investigate whether uric acid plays a role in PSP. METHODS We carried out a cross-sectional study to compare serum uric acid levels between PSP patients, PD patients, and healthy controls. We(More)
Parkinson’s disease (PD) is a neurodegenerative disease caused by both genetic and environmental factors. Sirtuins are highly-conserved, NAD-dependent class III deacetylases that regulate a variety of cellular functions. Most of the known sirtuins have been involved in animal models of neurodegenerative disorders, such as PD. Although seven sirtuin family(More)
BACKGROUND The clinical profile in vascular parkinsonism (VP) patients is well described in the literature, but little is known about the neuropsychological features of this disease. The aim of our study was to evaluate the clinical characteristics and the profile of cognitive impairment in patients with VP. METHODS We prospectively evaluated 12 patients(More)
BACKGROUND Tourette syndrome is a disorder characterized by persistent motor and vocal tics, and frequently accompanied by the comorbidities attention deficit hyperactivity disorder and obsessive-compulsive disorder. Impaired synaptic neurotransmission has been implicated in its pathogenesis. Our aim was to investigate the association of 28 candidate genes,(More)
The short-term benefits of levodopa/carbidopa intestinal gel (LCIG) in patients with advanced Parkinson’s disease (PD) are well documented, but the long-term benefits are still uncertain. The aim of this study was to investigate the motor and cognitive outcome of LCIG treatment in advanced PD after a follow-up period of at least 24 months. We assessed 29(More)
Mutations in FBXO7 (PARK15) have been associated with a syndrome characterized by early-onset progressive parkinsonism with and without pyramidal tract signs. Therefore, our aim was to analyze this gene in a population from southern Spain (338 Parkinson's disease [PD] patients and 330 unrelated control subjects) to elucidate the potential involvement of(More)
