RESUMEN
OBJECTIVE: The primary objective was to study the association between fingolimod and the frequency of depression, anxiety, and insomnia symptoms among a cohort of Multiple Sclerosis (MS) patients with stress. The secondary objective was to examine the association between patient characteristics and these psychiatric symptoms. PATIENTS AND METHODS: Patients with MS and stress were recruited according to the Arabic version of the Perceived Stress Scale (PSS). Psychiatric outcomes were measured by validated scales. Logistic regression was used to estimate adjusted odds ratios (aORs) with 95% confidence intervals (CIs). Data from 324 participants were analyzed. RESULTS: Fingolimod was associated with a significantly lower adjusted odds ratio for depression (aOR 0.58, 95% CI 0.35-0.97, p<0.05) but less associated with anxiety (aOR 0.63, 95% CI 0.35-1.01, p=0.05) and insomnia (aOR 0.88, 95% CI 0.52-1.51, p=0.64). CONCLUSIONS: Close monitoring of mental health is required for patients with MS using disease-modifying therapies.

BACKGROUND AND PURPOSE: The purpose was to examine the consequences of antiepileptic drug (AED) exposure during pregnancy on language abilities in children aged 5 and 8 years of mothers with epilepsy. METHODS: The study population included children of mothers with and without epilepsy enrolled in the Norwegian Mother and Child Cohort Study 1999-2008. Mothers prospectively provided information on epilepsy diagnosis, AED use during pregnancy and the child's language abilities at age 5 and 8 years, in questionnaires with validated language screening tools. AED concentrations in gestation week 17-19 and in the umbilical cord were measured. RESULTS: The study population included 346 AED-exposed and 388 AED-unexposed children of mothers with epilepsy, and 113 674 children of mothers without epilepsy. Mothers of 117 and 121 AED-exposed children responded to the questionnaires at age 5 and 8 years, respectively. For AED-exposed children, the adjusted odds ratio for language impairment was 1.6 [confidence interval (CI) 1.1-2.5, P = 0.03] at age 5 years and 2.0 (CI 1.4-3.0, P < 0.001) at age 8 years, compared to children of mothers without epilepsy. Children exposed to carbamazepine monotherapy had a significantly increased risk of language impairment compared to control children at age 8 years (adjusted odds ratio 3.8, CI 1.6-9.0, P = 0.002). Higher maternal valproate concentrations correlated with language impairment at age 5 years. Periconceptional folic acid supplement use protected against AED-associated language impairment. CONCLUSION: Foetal AED exposure in utero is associated with an increased risk of language impairment in children aged 5 and 8 years of mothers with epilepsy. Periconceptional folic acid use had a protective effect on AED-associated language impairment.

OBJECTIVES: The present paper summarizes and compares data from our studies on subjective and objective sleep quality and pain thresholds in tension-type headache (TTH), migraine, and controls. MATERIAL AND METHODS: In a blinded controlled explorative study, we recorded polysomnography (PSG) and pressure, heat, and cold pain thresholds in 34 controls, 20 TTH, and 53 migraine patients. Sleep quality was assessed by questionnaires, sleep diaries, and PSG. Migraineurs who had their recordings more than 2 days from an attack were classified as interictal while the rest were classified as either preictal or postictal. Interictal migraineurs (n=33) were also divided into two groups if their headache onsets mainly were during sleep and awakening (sleep migraine, SM), or during daytime and no regular onset pattern (non-sleep migraine, NSM). TTH patients were divided into a chronic or episodic group according to headache days per month. RESULTS: Compared to controls, all headache groups reported more anxiety and sleep-related symptoms. TTH and NSM patients reported more daytime tiredness and tended to have lower pain thresholds. Despite normal sleep times in diary, TTH and NSM had increased slow-wave sleep as seen after sleep deprivation. Migraineurs in the preictal phase had shorter latency to sleep onset than controls. Except for a slight but significantly increased awakening index SM, patients differed little from controls in objective measurements. CONCLUSIONS: We hypothesize that TTH and NSM patients on the average need more sleep than healthy controls. SM patients seem more susceptible to sleep disturbances. Inadequate rest might be an attack-precipitating- and hyperalgesia-inducing factor.

OBJECTIVE: Neurophysiological studies have shown a fluctuating neural dysfunction in migraine. This pathophysiological feature has not previously been investigated by quantitative electroencephalography (QEEG). The alpha rhythm is especially interesting, because it is influenced by ischemia and neuronal dysfunction within the posterior circulation area. METHODS: We investigated alpha peak frequency, variability, peak power and asymmetry in 41 migraineurs and 32 controls. Electroencephalography (EEG) was recorded on three random days and retrospectively classified as preattack, attack, postattack or interictal, based on the patient's headache diaries. We also searched for correlations between alpha rhythm parameters and disease duration, attack duration, attack frequency, pain intensity and photophobia. RESULTS: Peak frequency reduction correlated with increasing disease- and attack duration. Frequency variability increased before the attack, while peak power increased during the attack. Alpha peak width, peak frequency and peak power were similar for migraineurs and controls in the interictal period. CONCLUSION: The accumulated burden of migraine caused slight alterations in the physiology of the visual cortex. Small alpha rhythm changes were observed along the migraine cycle. SIGNIFICANCE: This is a longitudinal, controlled study. It is the first to report changes in alpha rhythm with increased migraine load, even when the QEEG is not influenced by recent or imminent attacks.
