The frequency of sleep disturbances in patients with epilepsy and their impact on quality of life (QoL) have been documented in a few reports, and the results are conflicting. We identified 124 consecutive epilepsy out-patients who visited the epilepsy out-patient clinics at the University Hospital of Alexandroupolis, the AHEPA Hospital in Thessaloniki and(More)
UNLABELLED Interleukin-15 (IL-15) is a novel proinflammatory cytokine having similar biological activities to IL-2 which is implicated in the pathogenesis of multiple sclerosis. It is produced by activated blood monocytes, macrophages and glial cells. There is little information about the involvement of IL-15 in the development of multiple sclerosis (MS).(More)
Aim of the report was the study of the clinical features of neurosyphilis in the last 40 years (1965-2005). The investigation was based on the retrospective review of patients with neurosyphilis hospitalized in our hospital from 1965 to 2005 (period A: 1965-1984 and B: 1985-2005). Eighty one patients with neurosyphilis were studied. Typical forms represent(More)
Auditory event-related potentials (AERP) were elicited in 68 epileptic patients and 30 age-matched controls. Epileptic patients had significantly prolonged N2 and P300 (P3) latencies compared with controls. Seven patients were above the range of 3 standard deviations from the control mean values. Amongst epileptics, patients with temporal lobe epilepsy had(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)
Sedated sleep and sleep deprivation are commonly used methods to increase the diagnostic yield of the electroencephalogram (EEG), especially in the evaluation of people with epilepsy, but the rate of activation achieved by them is controversial, as is the issue of whether it is sleep itself, or sleep deprivation which is responsible for their alleged(More)
We investigated the effects of add-on lamotrigine treatment on plasma glutamate (Glu) levels, in 29 epileptic patients. Plasma Glu levels were determined by high-performance liquid chromatography at baseline and at 1 and 3 months post-treatment. In patients with a seizure reduction of > or = 66% a decrease of Glu at month 1 was noted, followed by return to(More)
Auditory event-related potentials (AERP) were elicited in 47 patients with relapsing-remitting (RR) multiple sclerosis (MS) and 24 age-matched controls. MS patients had significantly prolonged N2 and P3 latencies as well as low P3 amplitude compared with controls. Seven of them exceeded 3 standard deviations from the control mean values. The observed N2 and(More)
Auditory ERP (AERP) studies have been performed in 56 patients with central nervous system disturbances. Forty seven patients (90.5%), had AERP component abnormalities concerning mainly P300 topography alterations and secondarily P300 latency prolongation. It is concluded that P300 is a very useful tool in clinical neurology and that P300 topography or(More)
OBJECTIVES We evaluated cross-sectionally the associations of depression and anxiety with age, sex, duration of illness, educational level, degree of disability and treatment with interferon-beta in outpatients with relapsing-remitting multiple sclerosis (RRMS) during a clinically stable phase of their illness. MATERIALS AND METHODS The depression status(More)
