OBJECTIVE To assess the impairment in daily living activities in older people with age related changes in white matter according to the severity of these changes. DESIGN Observational data collection and follow-up of a cohort of older people undergoing brain magnetic resonance imaging after non-disabling complaints. SETTING 11 European centres. (More)
BACKGROUND Previous research has indicated that corpus callosum atrophy is associated with global cognitive decline in neurodegenerative diseases, but few studies have investigated specific cognitive functions. OBJECTIVE To investigate the role of regional corpus callosum atrophy in mental speed, attention and executive functions in subjects with(More)
BACKGROUND Both types of cerebral white matter hyperintensities, periventricular (PVL) and deep white matter lesions (DWML) have been previously associated with the development of depression in older subjects. However, it remains controversial as to whether PVL, DWML, or both are most strongly associated with depression and this was the aim of the current(More)
Neuroimaging changes in the cerebral subcortical white matter (WMC) are recognized with the highest frequency in elderly subjects, particularly in those with vascular risk factors. WMC have been consistently reported to be associated with global or selective cognitive deficits, depression, motor and gait impairment. All these deficits are main contributors(More)
FLAIR and diffusion-weighted MRI were obtained twice (mean interval 20 +/- 4 months) in 10 patients with leukoaraiosis. At follow-up, visual extension of leukoaraiosis was unchanged, whereas the median of whole brain apparent diffusion coefficient (WB-ADC) histogram was increased (p= 0.008) and brain volume index (BVI) was decreased (p = 0.006). WB-ADC(More)
Parkinson's disease is a neurodegenerative disorder which is mainly characterized by degeneration of the dopaminergic cells in the nigro-striatal system. Due to a lowered L-tyrosine 3-monooxygenase activity, L-tyrosine is not sufficiently transformed to L-DOPA. To date the most common therapy is the administration of the dopamine precursor L-DOPA, with(More)
Evidence-based medicine's aims are to retrieve, screen and compound the best external evidence with the experience of the physician, and to best respond to the specific medical need of each individual patient. Clinical questions are better answered when good systematic reviews of randomised trials or good randomised clinical trials are available. On the(More)
OBJECTIVE To assess the ability of the Wisconsin Gait Scale to evaluate qualitative features of changes in hemiplegic gait in post-stroke patients. DESIGN A prospective observational study. SUBJECTS Ten healthy subjects and 56 hemiplegic outpatients, more than 12 months post-stroke, consecutively admitted in a rehabilitation centre. METHODS Patients(More)
The gastrin-releasing peptide receptor (GRPR) is overexpressed in a variety of human malignancies, including prostate cancer. Bombesin (BBN) is a 14 amino acids peptide that selectively binds to GRPR. In this study, we developed two novel Al(18)F-labeled lanthionine-stabilized BBN analogs, designated Al(18)F-NOTA-4,7-lanthionine-BBN and(More)
