Temporal discrimination thresholds (TDT) for recognition of paired sensory (tactile, auditory and visual) stimuli given over a wide range of time intervals were assessed in 44 patients with Parkinson's disease (PD) and 20 age-matched normal subjects. A significant increment in TDT for all three sensory modalities was found in PD patients compared with(More)
We investigated the prevalence of dementing disorders in the city of Pamplona, Spain, using a door-to-door two-phase approach. We first administered the Cambridge Examination of Mental Disorders of the Elderly (CAMDEX) to all survivors, as of March 1, 1991, of a probability sample of the total population identified in 1989 (n = 1,127). Using specified(More)
BACKGROUND A recent pilot study suggested spasticity improvement during glatiramer acetate (GA) treatment in multiple sclerosis (MS) patients who previously received interferon-β (IFN-β). OBJECTIVE To evaluate changes in spasticity in MS patients switching from IFN-β to GA. METHODS Observational, multicentre study in patients with relapsing-remitting MS(More)
Somaesthetic temporal discrimination (STD) is the ability to perceive as separate two successive somaesthetic stimuli applied to the same or different parts of the body. Paired electrical stimuli were applied to the index finger, using different time-intervals, to study the STD threshold (STDT) in 84 normal subjects and 51 patients with focal cerebral(More)
OBJECTIVES Previous studies have reported an increased risk for epileptic seizures in multiple sclerosis (MS) patients. However, data on the pathogenesis of seizures remain inconclusive. The aim of our study is to evaluate prevalence, clinical and paraclinical features of epileptic attacks in our MS cohort and to search MS-specific risk factors for(More)
INTRODUCTION. Takotsubo syndrome (TTS) is a rare condition that mimics an acute myocardial infarction. It is associated with precordial pain, ST segment elevation, absence of coronary occlusion and reversible deformation of the left ventricle due to anteroapical dyskinesia that is reminiscent of a Japanese art of fishing octopuses (tako-tsubo). It is(More)
OBJECTIVE Vitamin D deficiency has been linked to increased risk of multiple sclerosis (MS) and poor outcome. However, the specific role that vitamin D plays in MS still remains unknown. In order to identify potential mechanisms underlying vitamin D effects in MS, we profiled epigenetic changes in vitamin D receptor (VDR) gene to identify genomic regulatory(More)
INTRODUCTION Recent studies have shown the need to optimise the management of patients after a first attack suggestive of multiple sclerosis (MS). Our aim is to determine whether the results from follow-ups in these studies are reproducible within a Spanish multi-centre context. PATIENTS AND METHODS The PREM study (observational prospective Spanish(More)
