Over a 3-year period cognitive deterioration can be expected in approximately one-third of MS patients with relatively short disease duration. The SDMT is particularly suitable for longitudinal assessment of MS-related cognitive changes.

SUMMARYThe Italian League Against Epilepsy has issued evidence-based guidelines to help practicing physicians in their decision to stop or withhold antiepileptic drugs (AEDs) in patients achieving a prolonged period of seizure freedom. Six adult and two child neurologists, divided into four pairs, critically appraised 128 published reports and provided graded recommendations answering 15 key questions: length of the seizure-free period after treatment initiation, difference in seizure-free periods in children and adults, electroencephalography (EEG) pattern at the time of discontinuation, etiology of epilepsy, seizure type(s), patient's age and sex, family history of epilepsy, history of febrile seizures, epilepsy syndrome, seizure frequency before entering remission, duration of active epilepsy, tapering period, number and type of AEDs taken at time of discontinuation, combination of risk factors for recurrence, and length of patient monitoring after treatment discontinuation. Based on the available data, the following recommendations can be outlined: (1) antiepileptic treatment might be discontinued after a minimum period of 2 years of seizure freedom; shorter seizure-free periods are associated to a higher risk of relapse; (2) in children, AED discontinuation could be considered after less than two seizurefree years because of a marginally higher risk of relapse for early withdrawal; (3) factors, such as abnormal EEG (including epileptiform abnormalities) at the time of treatment discontinuation, a documented etiology of seizures (including mental retardation, perinatal insults, and abnormal neurologic examination), partial seizures, or an older age at disease onset, enhance the risk of relapse; however, patients should not be encouraged to withhold treatment unless a combination of two or more of these factors is present; (4) female sex, family history of epilepsy, history of febrile seizures, disease length/severity, and number and type of drugs taken should not influence the decision to stop treatment; (5) epilepsy syndrome should be always included in the decision process; (6) slow (at least 6 months) AED discontinuation should be encouraged; in any case the duration of the tapering period should be tailored to the patient's needs and preference; and (7) patient discontinuing treatment should be followed for no <2 years. As a general habit, the decision to stop treatment should be discussed and shared with each patient, taking into account social and personal complications of a seizure relapse and the medical complications of chronic AED treatment.

SUMMAR Y The increased tendency to fall asleep during the daytime together with increased wakefulness during the night has been demonstrated in patients with advanced Alzheimer's disease (AD). The aim of this study was to assess daytime sleep propensity in a cohort of patients with mild/moderate AD and to correlate it with cognitive impairment. Twenty drug-free AD patients meeting the NINCDS-ADRDA criteria for probable AD were evaluated. According to their Clinical Dementia Rating scores, subjects were classified into mild (CDR1; n ¼ 11) and moderate (CDR2; n ¼ 9) dementia patients. A group of 12 healthy subjects was taken as controls. The subjects were evaluated by the multiple sleep latency test (MSLT) after their nocturnal sleep pattern had been assessed by a polysomnographic recording throughout the night before. Both groups of AD patients showed a higher level of daytime sleepiness, which was statistically significant for mean daytime sleep latency (MDSL) (controls versus CDR1 and versus CDR2, CDR1 versus CDR2) and for 10:00 and 12:00 hour naps (controls versus CDR1, controls versus CDR2

ObjectiveTo evaluate whether vagus nerve stimulation (VNS) as adjunct to best medical practice (VNS + BMP) is superior to BMP alone in improving long-term health-related quality of life (HRQoL).MethodsPuLsE (Open Prospective Randomized Long-term Effectiveness) was a prospective, randomized, parallel-group, open-label, and long-term effectiveness study (conducted at 28 sites in Europe and Canada). Adults with pharmacoresistant focal seizures (n = 112) received VNS + BMP or BMP (1:1 ratio). Medications and VNS parameters could be adjusted as clinically indicated for optimal seizure control while minimizing adverse effects. Primary endpoint was mean change from baseline HRQoL (using Quality of Life in Epilepsy Inventory-89 total score; QOLIE-89). Secondary endpoints included changes in seizure frequency, responder rate (≥50% decrease in seizure frequency), Centre for Epidemiologic Studies Depression scale (CES-D), Neurological Disorders Depression Inventory-Epilepsy scale (NDDI-E), Clinical Global Impression-Improvement scale (CGI-I), Adverse Event Profile (AEP), and antiepileptic drug (AED) load. The study was prematurely terminated due to recruitment difficulties prior to completing the planned enrollment of n = 362. Results for n = 96 who had baseline and at least one follow-up QOLIE-89 assessment (from months 3-12) were included in this analysis. Mixed model repeated measures (MMRM) analysis of variance was performed on change from baseline for the primary and secondary endpoints.ResultsSignificant between-group differences in favor of VNS + BMP were observed regarding improvement in HRQoL, seizure frequency, and CGI-I score (respective p-values < 0.05, 0.03, and 0.01). More patients in the VNS + BMP group (43%) reported adverse events (AEs) versus BMP group (21%) (p = 0.01), a difference reflecting primarily mostly transient AEs related to VNS implantation or stimulation. No significant difference between treatment groups was observed for changes in CES-D, NDDI-E, AEP, and AED load.SignificanceVNS therapy as a treatment adjunct to BMP in patients with pharmacoresistant focal seizures was associated with a significant improvement in HRQoL compared with BMP alone.

Mild AD significantly impaired simulated driving fitness, while MCI limitedly affected driving performance. Unsafe driving behaviour in AD patients was not predicted by MMSE scores.
