BACKGROUND AND PURPOSE Patients with obstructive sleep apnea syndrome (OSAS) present cognitive deficits similar to those observed with aging. The aim of the study was to assess the effects of age on cognitive functions in OSAS patients. It was hypothesized that older OSAS patients will exhibit significant cognitive dysfunction relative to younger OSAS(More)
We assessed the health-related quality of life (HRQoL) of patients with myasthenia gravis (MG) and correlated it with the physician's measurements of MG. Patients with MG were evaluated by means of (1) self-administered questionnaires, (2) clinical examination, (3) Osserman classification, (4) anti-AChR antibody, and (5) neurophysiology. Relationships(More)
We describe the development and validation of an outcome measure for patients with myasthenia gravis (MG) and show the correlation of the items with conventional MG measurements. In stage I, item generation, a group of methodologists, clinical experts generated a list of 56 items. The list was based on (1) a previous study on an MG sample, (2) clinical(More)
OBJECTIVE To investigate the regional cerebral perfusion in patients with idiopathic REM behavior disorder (RBD) in order to establish the topography of networks involved. METHODS We performed cerebral blood flow evaluation using (99m)Tc-Ethylene Cysteinate Dimer (ECD) SPECT on eight patients with polysomnographically confirmed RBD and nine age-matched(More)

Incidence of neuroepithelial Primary Brain Tumors (nPBT) varies, ranging from 7.3 to 11.6 cases/100,000/year across Europe. We present incidence and survival of nPBT in the Emilia-Romagna region (ER), Italy. This study is the largest in Southern Europe. Specialists in neurosurgery, neurology, neuroradiology, oncology, radiotherapy, genetics, and pathology(More)
One of the fundamental dynamics of psychic adaptation to both intra-psychic and relational stimuli is the defense mechanism of repression in correlation with that of isolation. Our work is concerned with testing whether the use of these mechanisms can constitute, in the case of MS patients, one of the factors which would explain various psychological(More)
