- Purpose: To evaluate the incidence of unprovoked seizures in children and the prevalence of related neurodevelopmental comorbidities at the time of the presumed first seizure and six months thereafter. Methods: The medical records of all children (0-18 years of age) seeking medical attention as the result of a first unprovoked seizure between September 1, 2001 and December 31, 2006, and registered in the population-based Stockholm Incidence Registry of Epilepsy (SIRE) were reviewed. Neurodevelopmental comorbidities were evaluated on the basis of the medical records from this first visit and from other healthcare during the following six months. Results: The incidence of unprovoked seizures was between 30 and 204/100,000 person years (n=766) in the different age groups. It was highest among the youngest children and lowest among the 18-year-olds with small gender differences. The most common neurodevelopment comorbidities were developmental delay (22%, CI: 19-25%), speech/language and learning difficulties (23%, CI: 20-26%) and intellectual disability (16%, CI: 13-18%). The types of neurodevelopmental comorbidity varied by age at the time of seizure onset, with cerebral palsy being more common among the 0-5-year-olds, attention deficits among the 6-16-year-olds, and autism and psychiatric diagnosis among the older children. An associated neurodevelopmental comorbidity was more common among those experiencing recurrent than single seizures during follow-up six months from the index seizure (42% versus 66%). In 68% (CI: 64-71%) of the children there was no known or suspected neurodevelopmental comorbidity. Conclusion: The incidence of unprovoked, non-febrile seizures among 0-18-year-olds included in the SIRE was 67/100,000 person-years. Neurodevelopmental comorbidities were common already at the time of onset of the seizure disorder, indicating that neither seizure treatment nor seizures were the underlying cause of other neurodevelopmental symptoms in these patients during the period studied.

- Objective: The aim of this study is to systematically review the scientific literature to investigate if use of antiepileptic drugs (AEDs) is associated with falls and/or recurrent falls in old age. Method: We searched the literature for relevant articles in PubMed and Embase published up until 3rd December 2015. Studies on people aged 60 years and over with an observational design assessing the risk of fall in people exposed to AEDs compared to people not exposed to AED were included. Results: We found 744 studies by searching Medline and Embase and an additional 9 studies by reviewing relevant reference lists. Of these studies, 13 fulfilled our predefined criteria. The articles were of various study design, sizes and follow-up times, and presented the results in different ways. Also, confounder adjustment varied considerably between the studies. Ten studies presented results for the association between use of any AED and any fall/injurious fall. Of these studies, 6 presented adjusted estimates, of which all but one showed statistically significant associations between use of any AED and any fall/injurious fall. Six studies investigated the association between use of any AED and recurrent falls. Of these, only 3 studies presented adjusted effect estimates of which 2 reached statistical significance for the association between use of AEDs and recurrent falls in elderly people. Conclusion: Our results indicate an association between use of AEDs and risk of falls and recurrent falls in older people. This finding may be clinically important given that a substantial amount of older people use these drugs. However, further research is needed to increase the knowledge about the actual risk of falls when using these drugs in old age.

- Purpose: To follow children with newly diagnosed unprovoked seizures to determine (1) whether the prevalence of neurodevelopmental comorbidities and cerebral palsy (CP) changed after the initial seizure, and (2) the association between studied comorbidities and seizures 13-24 months after seizure onset or initiation of treatment. Methods: Analyses were based on 750 children (28 days-18 years) with a first unprovoked seizure (index) included in a population-based Incidence Registry in Stockholm between 2001 and 2006. The children were followed for two years and their medical records were examined for a priori defined neurodevelopmental/psychiatric comorbidities and CP and seizure frequency. Baseline information was collected from medical records from before, and up to six months after, the index seizure. Odds ratios (OR) of repeated seizures 13-24 months after the first seizure or after initiation of anti-epileptic drug treatment was calculated by logistic regression and adjusted for age and sex. Results: At baseline, 32% of the children had neurodevelopmental/psychiatric comorbidities or CP compared to 35%, 24 months later. Children with such comorbidities more often experienced seizures 13-24 months after the index seizure (OR 2.87, CI 2.07-3.99) with the highest OR in those with CP or attention deficit hyperactivity disorder (ADHD). Children diagnosed at age < 1 year exhibited the highest prevalence of comorbidities as well as OR for repeated seizures. A combination of young age and comorbidity was associated with an OR for repeated seizures of 5.12 (CI 3.03-8.65). Among the children without comorbidities 76% were seizure free 13-24 months after the index seizure or after initiation of AED treatment compared to 53% of children with comorbidities. Conclusions: This study indicates that neurodevelopmental comorbidities and CP in children with epilepsy tend to be present already at seizure onset and that such comorbidities are strong indicators of poor outcome regarding seizure control with or without treatment.

- To evaluate the effects of eslicarbazepine acetate (ESL) on lipid metabolism and to determine whether reduced statin exposure during ESL therapy has clinical consequences.We conducted a post-hoc analysis of pooled data for serum lipids (laboratory values) from three phase III, multicenter, randomized, double-blind, placebo-controlled trials of adjunctive ESL therapy (400, 800, or 1200mg once daily) in patients with treatment-refractory partial-onset seizures. Changes from baseline in serum lipid levels were analyzed according to use of statins and/or enzyme-inducing antiepileptic drugs (EIAEDs) during the baseline period.In total, 426 and 1021 placebo- and ESL-treated patients, respectively, were included in the analysis. With regard to the changes from baseline in serum concentrations, there were statistically significant differences between the placebo and ESL 1200mg QD groups, for both total cholesterol (TC) and high-density lipoprotein cholesterol (HDL-C), but the effect sizes were small (+4.1mg/dL and +1.8mg/dL, respectively). A small but significant difference in low-density lipoprotein cholesterol (LDL-C; -5.0mg/dL) was observed between the ESL 400mg QD group and the placebo group. In patients not taking a concomitant EIAED, there were no changes with ESL 400mg QD, but modest and statistically significant increases in cholesterol fractions (TC, LDL-C and HDL-C) with ESL 800mg QD (<6mg/dL) and ESL 1200mg QD (<10mg/dL). ESL had no consistent effect on lipids in patients taking a concomitant EIAED. In patients taking statins during baseline, there were no clinically relevant changes in serum lipids during use of ESL, although the subgroups were small.These results suggest that ESL does not appear to have clinically significant effects on serum lipids, nor does the pharmacokinetic interaction between ESL and statins have an impact on serum lipid concentrations.
