There is evidence that proneness to experience psychological distress is a risk factor for Alzheimer's disease (AD). In the present study, an attempt is made to examine the possible association between stressful events and cognitive impairment of the elderly, based on a sample of 1271 patients (500 male, 771 female) diagnosed with dementia according to the(More)
BACKGROUND Depression and anxiety are common psychiatric symptoms in patients with epilepsy, exerting a profound negative effect on health-related quality of life. Several issues, however, pertaining to their association with psychosocial, seizure-related and medication factors, remain controversial. Accordingly, the present study was designed to(More)
BACKGROUND TMS is being increasingly used as a noninvasive brain stimulation technique for the therapeutic management of partial epilepsies. However, the acute effects of TMS on epileptiform discharges (EDs, i.e. interictal epileptiform activity and subclinical electrographic seizure patterns) remain unexplored. OBJECTIVE To investigate whether TMS can(More)
BACKGROUND Adverse reactions, particularly injection site reactions (ISRs), are common reasons for nonadherence to injectable multiple sclerosis (MS) treatments. Adherence to MS treatment is important to ensure good treatment outcomes. OBJECTIVE The aim of this study was to assess the local tolerability of subcutaneous (SC) serum-free interferon (IFN)(More)
Other outcomes assessed up to week 24 (last MRI scan) • Change in T2 lesion volume from baseline • Proportion of patients free from new T2 lesions • Gd+ lesion count • Proportion of patients free from Gd+ lesions • Proportion of patients free from relapses Analysis sets • Modified full analysis set (mFAS): patients completing 8 weeks of fingolimod therapy(More)
BACKGROUND The aim of the study was to assess the plasma levels of homocysteine in patients with multiple sclerosis (MS) and to investigate whether an association with depression exists. METHODS Plasma homocysteine (Hcy), vitamin B12 and plasma folate were measured in 65 moderately disabled patients with relapsing/remitting MS (RR-MS) and 60 healthy(More)
OBJECTIVE To investigate, by transcranial magnetic stimulation, the effects of valproate on silent period and corticomotor excitability. METHODS thirty patients with generalized epilepsy were studied at baseline, and re-examined 4 (S1) and 25 (S2) weeks after the administration of valproate (mean dose: 1040 +/- 284 mg). Transcranial magnetic stimulation(More)
BACKGROUND AND OBJECTIVES Numerous controlled clinical trials have demonstrated the safety and efficacy of pregabalin in the treatment of neuropathic pain. The objectives of the present study were to assess the impact of pregabalin under real-world conditions on pain, pain-related sleep interference and general well-being, and to assess the tolerability and(More)
Cognitive event-related potentials (ERPs) are widely employed in the study of dementive disorders. The morphology of averaged response is known to be under the influence of neurodegenerative processes and exploited for diagnostic purposes. This work is built over the idea that there is additional information in the dynamics of single-trial responses. We(More)
