Health-related quality of life (HRQoL) has been more intensively studied in multiple sclerosis (MS) than in any other neurological disorder. Traditional medical models of impairment and disability are an incomplete summary of disease burden. Quality of life can be thought of as the sum of all sources of satisfaction (including anticipated sources) minus all(More)
The prevalence of Parkinson's disease (PD) and other types of parkinsonism in three elderly populations of central Spain was investigated using a door-to-door, two-phase approach. This design called for the administration of a brief questionnaire to subjects 65 years of age or older taken from the census of one urban municipality of Greater Madrid(More)
There are few data on the co-morbidity of essential tremor (ET) with depression. To assess the associations of ET with self-reported depression and antidepressant medication use. In a population-based study in central Spain, participants were evaluated at baseline (1994-1995) and 3 years later. Self-reported depression and use of antidepressant medications(More)
BACKGROUND AND PURPOSE Although digital subtraction angiography (DSA) is the reference standard for assessing carotid arteries, it is uncomfortable for patients and has a small risk of disabling stroke and death. These problems have fueled the use of spiral CT angiography and MR angiography. We prospectively compared elliptic centric contrast-enhanced MR(More)
Although essential tremor (ET) is considered the most prevalent adult movement disorder, the available information on its prevalence and distribution worldwide is not completely understood. We investigated the prevalence and distribution of ET in three elderly Spanish populations using a door-to-door, two-phase approach. A brief screening instrument was(More)
OBJECTIVES Until relatively recently southern Europe was regarded as having a medium to low multiple sclerosis prevalence, of about 20 or less per 100,000. However, recent studies in Sardinia, Sicily, continental Italy, Cyprus and Spain have yielded higher MS prevalence rates, between 32 and 102.6 per 100,000. We present the results of a prevalence study of(More)
Parkinson's disease (PD) is a neurodegenerative disorder that imposes an important burden upon the patient's caregiver. This study aims at assessing caregiver burden (CB) and analyzing its relationship with sociodemographic, emotional, and functional factors, as well as health-related quality of life (HRQoL). The following measures were applied to 80(More)
Essential tremor (ET) is a late-life neurological disease. Mild cognitive deficits as well as an association with prevalent dementia have been reported in recent case-control studies. We determined whether ET was associated with an increased risk of incident dementia. In a population-based study of older people in central Spain (NEDICES), nondemented ET(More)
Essential tremor (ET) has been associated with a spectrum of clinical features, with both motor and nonmotor elements, including cognitive deficits. We employed resting-state functional magnetic resonance imaging (fMRI) to assess whether brain networks that might be involved in the pathogenesis of nonmotor manifestations associated with ET are altered, and(More)
To evaluate the mortality, thirteen years after the baseline wave (1994), of participants suffering dementia in the Neurological Disorders in Central Spain (NEDICES) Cohort Study, we conducted a population-based cohort study in the elderly (65 years and more) with 5,278 screened participants at baseline. Mortality has been evaluated by means of the National(More)
