Interictal Cognitive Performance in Children and Adolescents With Primary Headache: A Narrative Review. Front Neurol 2022; 13:898626. [PMID: 35911918 PMCID: PMC9326001 DOI: 10.3389/fneur.2022.898626] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Accepted: 06/21/2022] [Indexed: 11/13/2022] Open
Abstract
Primary headache is a very common and disabling disease. The burden of pain and recurrent attacks may lead to a poor quality of life, anxiety and depression. An increased risk of low functioning and curricular performances in young patients with primary headache has been described. The mechanisms underlying the relationship between migraine and poor school achievement may be various and could be a reflection of weak cognitive skills. Data concerning the cognitive functioning in the free pain interval in pediatric age are under-investigated and results are far from conclusive. The present review article suggests that, though considered a benign disease, pediatric migraine may be associated to altered neuropsychological functioning in the interictal phase. Although children and adolescents with migraine generally have a normal intelligence, they may show a not homogeneous cognitive profile, characterized by possible difficulties in verbal skills, in particular comprehension abilities. Pediatric primary headache may present altered neuropsychological functioning involving attentional resources, processing speed and memory, particularly verbal memory. Given the impact that this disease can have on school performance and the tendency to persist from childhood to adulthood, a cognitive screening in young patients affected by primary headache is pivotal. Additional neuropsychological research using more homogenous methods is needed.

Prognosis of headache in children: a 25-year follow-up. Childs Nerv Syst 2022; 38:619-626. [PMID: 35059785 DOI: 10.1007/s00381-021-05420-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Accepted: 11/19/2021] [Indexed: 11/03/2022]
Abstract
AIM To describe the natural history, evaluate the long-term prognosis, and identify predictors of a favorable outcome of childhood migraines in a cohort of children who had been diagnosed with migraine 25 years before. METHODS One hundred eighteen children with headache (ages 2 to 15), observed in a headache outpatient clinic of a University Hospital in 1994, by one of the authors, were revaluated in 2019/2020 by a standardized telephone interview specifying headache characteristics, treatment, precipitants, and family history. Headache diagnosis at follow-up was based on ID-Migraine and confirmed by a semistructured interview. RESULTS Revaluation was achieved for 88 (75%) patients (43 with migraine), 47 women and age average 41.2 ± 3.2. Over the follow-up (average 25.5 years), 33% of the patients had experienced remission, 41% maintained the same diagnosis, and 26% evolved into a different headache. Sixty six percent reported an improvement. Only eight patients were attending regular consultations because of headache. Male sex came out as the only predictor of a favorable outcome. CONCLUSION Most patients (66%) with pediatric headache continue to experience headache although reporting a significant improvement. Boys tended to remit more often than girls. This data suggests that age, genetics, and hormonal factors may play an important role in migraine phenotypic expression.

Headache in ADHD as comorbidity and a side effect of medications: a systematic review and meta-analysis. Psychol Med 2022; 52:14-25. [PMID: 34635194 PMCID: PMC8711104 DOI: 10.1017/s0033291721004141] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 09/08/2021] [Accepted: 09/23/2021] [Indexed: 01/02/2023]
Abstract
There is mixed evidence on the association between headache and attention-deficit/hyperactivity disorder (ADHD), as well as headache and ADHD medications. This systematic review and meta-analysis investigated the co-occurrence of headache in children with ADHD, and the effects of ADHD medications on headache. Embase, Medline and PsycInfo were searched for population-based and clinical studies comparing the prevalence of headache in ADHD and controls through January 26, 2021. In addition, we updated the search of a previous systematic review and network meta-analysis of double-blind randomized controlled trials (RCTs) on ADHD medications on June 16, 2020. Trials of amphetamines, atomoxetine, bupropion, clonidine, guanfacine, methylphenidate, and modafinil with a placebo arm and reporting data on headache as an adverse event, were included. Thirteen epidemiological studies and 58 clinical trials were eligible for inclusion. In epidemiological studies, a significant association between headache and ADHD was found [odds ratio (OR) = 2.01, 95% confidence interval (CI) = 1.63-2.46], which remained significant when limited to studies reporting ORs adjusted for possible confounders. The pooled prevalence of headaches in children with ADHD was 26.6%. In RCTs, three ADHD medications were associated with increased headache during treatment periods, compared to placebo: atomoxetine (OR = 1.29, 95% CI = 1.06-1.56), guanfacine (OR = 1.43, 95% CI = 1.12-1.82), and methylphenidate (OR = 1.33, 95% CI = 1.09-1.63). The summarized evidence suggests that headache is common in children with ADHD, both as part of the clinical presentation as such and as a side effect of some standard medications. Monitoring and clinical management strategies of headache in ADHD, in general, and during pharmacological treatment are recommended.

Abstract
INTRODUCTION The International Headache Society criteria were written in order to help physicians establish a headache diagnosis. However, sometimes children with headache do not seem to fit any diagnosis. The purpose of our study was to assess the application of the criteria in a clinical setting. METHODS Medical records of children referred for primary headache to the pediatric neurology clinic at Bnai Zion Medical Center from 2008 to 2017 were assessed. RESULTS A total of 989 patients (range 6-18 years; 53% female) were assessed at our neurology clinic. Twenty-four percent (n = 241) were diagnosed with tension-type headache, 26% (n = 256) with migraine, and 4.5% (45) with mixed headache. In 41.5% (410), we were unable to reach a specific diagnosis. No differences in gender or age were found between the groups. Children in the migraine group used more analgesic treatments to stop the headache attacks compared with the tension-type headache group (50% vs 38%, P = .001). Patients diagnosed with tension-type headache reported having more emotional difficulties (P = .001). No significant differences were found in headache characteristics (ie, location, sidedness, character), frequency, or intensity between the younger children (ages 6-11) and the adolescents (ages 12-18) within either the tension-type headache or migraine groups. CONCLUSIONS Retrospective application of International Headache Society criteria in a large cohort of children with headaches failed to diagnose a specific type of headache in 41.5% of children. Migraine and tension-type headache were equally prevalent, and both constituted a major burden on our patients' everyday lives. We found no major differences in frequency, intensity, and characteristics of pain between younger children and adolescents.

Abstract
Cognitive dysfunction has recently gained attention as a significant problem among migraine sufferers. All of the clinical studies show poor cognitive performance during migraine attacks, though, the interictal data are conflicting. Migraineurs show impaired cognitive function interictally in most of the clinic-based studies. Population-based studies did not reveal a difference in cognitive functions between migraineurs and controls. The specific cognitive domains involved are information processing speed, basic attention, executive functions, verbal and non-verbal memory and verbal skills. Neurophysiological, imaging and pharmacological studies support clinical symptoms of cognitive impairment in migraine. Longitudinal studies do not suggest progressive cognitive decline over time in migraine patients. Preventive medications and comorbid disorders such as depression and anxiety can impact cognitive function, but cannot fully explain the cognitive impairment in migraine. In contrast to migraine, tension type or cluster headache are not associated with cognitive impairment, at least during headache-free periods.

Abstract
Headache is one of the most common neurological disorders in developmental age. Several studies investigated the relationship between headache and emotional/behavioral problems. We studied non-verbal cognitive abilities, including non-verbal memory and attention skills, in order to evaluate the impact of primary headache on these domains. The latest version of the cognitive battery Leiter International Performance Scale – Third Edition (Leiter-3), a non-verbal test, was administered to 35 children and adolescents affected by migraine or tension-type headache and to 23 healthy subjects. We found that frequency of attacks and headache disability (evaluated with the Pediatric Migraine Disability Assessment Score Questionnaire) significantly correlate with non-verbal memory and sustained attention skills. However, we found that headache disability has a significant impact on specific cognitive domains related to sustained attention and non-verbal memory skills. The relationship between headache and memory/attention deficits may have an explanation based on a possible common physiopathology ground, including noradrenergic and dopaminergic pathways.

Abstract
PURPOSE OF REVIEW Headache is a common complaint among children and adolescents. School functioning is one of the most important life domains impacted by chronic pain in children. This review discusses the epidemiological and pathophysiological connections between headaches and school functioning including a suggested clinical approach. RECENT FINDINGS The connection between recurrent and chronic headache and learning disabilities might be psychosocial (fear of failure) or anatomical (malfunctioning of the frontal and prefrontal areas). Only few population-based and clinical studies were done and good studies are still needed in order to understand the complex relationship better. However, relating to our patients' learning and school performance, history is crucial when a child with primary headaches is evaluated. Learning disabilities seem to have a high prevalence among children with primary headache syndromes especially migraine. The connection between the two is complex and might be either part of a common brain pathophysiology and/or a consequence of poor quality of life.

Metacognition and Headache: Which Is the Role in Childhood and Adolescence? Front Neurol 2017; 8:650.

Abstract
Headache, in particular migraine, is one of the most frequent neurological symptoms in children and adolescents and it affects about 60% of children and adolescents all over the world. Headache can affect several areas of child’s functioning, such as school, physical activities, peer, and family relationship. The global and severe burden of this disease requires a multidisciplinary strategy and an effective treatment addressed all of the patient’s needs and based on cutting-edge scientific research. In recent years, research has focused on cognitive factors specifically in functions called metacognitive processes. Metacognition can be defined as the knowledge, beliefs, and cognitive processes involved in monitoring, control, and assessment of cognition. Metacognition seems to be closely related to the ability of theory of mind, the ability to infer, and reason about the mental states of other people in order to predict and explain own behavior. Recent studies found a relationship between metacognitive skills and anxiety, depression, motivation, academic performance, human social interactions, and stress symptoms. This relationship is very interesting for headache treatment, because these factors are the most commonly reported triggers in this disorder and there is a high comorbidity with anxiety and depression in children and adolescents with headache. So, headache and these comorbidities, in particular anxiety and depression, may have in common persistent and maladaptive patterns of thinking which are related to maladaptive metacognitive beliefs. Further research should assess metacognitive processes of children and adolescents with headache in order to increase their ability to control their own cognitive processes and consequently monitor factors which may trigger the attacks.

Abstract
BACKGROUND The aim of this study was to evaluate the changes in the cognitive performance of migraine patients using a comprehensive series of cognitive/behavioral and electrophysiological tests. METHOD A randomized, cross-sectional, within subject approach was used to compare neuropsychological and electrophysiological evaluations from migrane-affected and healthy subjects. RESULTS Thirty-four patients with migraine (6 males, 28 females, average 36 years old) were included. Migraineurs performed worse in the majority of the Montreal Cognitive Assessment (MoCA) (p = 0.007) compared to the healthy subjects, significantly in language (p = 0.005), memory (p = 0.006), executive functions (p = 0.042), calculation (p = 0.018) and orientation (p = 0.012). Migraineurs had a lower score on the memory trial of the Rey-Osterrieth complex figure test (ROCF) (p = 0.012). The P3 latency in Fz, Cz, Pz was prolonged in migraineurs compared with the normal control group (P < 0.001). In addition, we analyzed significant correlations between MoCA score and the duration of migraine. We also observed that a decrease in the MoCA-executive functions and calculation score and in the ROCF-recall score were both correlated to the frequency of migraine. Migraineurs were more anxious than healthy subjects (p = 0.001), which is independent of cognitive testing. Differences were unrelated to age, gender and literacy. CONCLUSIONS Cognitive performance decreases during migraine, and cognitive dysfunction can be related to the duration and frequency of a migraine attack.

Abstract
The aim of this study was to assess the role of the Addenbrooke's cognitive examination test (ACE-R) in the evaluation of cognitive status in migraineurs interictally. A total of 44 adolescent patients and 44 healthy controls, matched by age and gender, have undergone ACE-R testing. Migraineurs were additionally questioned about migraine aura features and presence of higher cortical dysfunctions (HCD) during an aura. According to the questionnaire results, patients were subsequently divided into HCD and Non-HCD group. ACE-R scores of migraine patients were significantly lower than in healthy controls (93.68 ± 3.64 vs 96.91 ± 2.49; t = 4.852, p < 0.001). Also, subscores of memory and verbal fluency were significantly higher in the control population. There was no correlation of HCD occurrence with cognitive examination score, although Non-HCD subgroup achieved better score (93.13 ± 3.91 vs 94.29 ± 3.30; t = 1.053, p = 0.298). Findings have shown that migraineurs get lower ACE-R test scores, with a tendency to have a poorer outcome in more complex aura. Also, our study has revealed that the ACE-R test is an easily administered test for brief assessment of cognitive status in migraineurs. Future perspectives could be further evaluation of ACE-R test in larger sample size and the impact of migraine with aura on cognitive function in adolescents.

Abstract
It is well documented that headache is a multifactorial disorder which includes not only genetic, biological, medical and neuropsychological factor but also psychological and personality traits. The close relationship between stress and migraine attacks and the significant psychiatric comorbidities in migraine provide evidence of a “paradigm” of tight interaction between somatic and psychological aspects in paediatric migraine. In particular in younger children, an uncomfortable situation, a psychological problem or an emotional distress is rarely expressed directly but usually through physical symptoms. So migraine may be considered as a disorder of psychobiological adaptation in which genetic predisposition interplays with internal and/or external environmental influences such as psycho-emotional, climatic, hormonal, dietary or other factors.

Abstract
The purpose of this study was to compare differences in temperament and emotional and behavioral problems in a community sample of young children who experience headaches to those without such complaints. The whole sample was comprised 75 non-referred, preschool-aged children (3-5 years old), including 22 with headache complaints and 53 without headaches (control group). The children's headache symptoms were assessed with a questionnaire that was given to the mothers. Rothbart's Children's Behavior Questionnaire was used to assess temperament, and the Child Behavior Checklist 1 ½-5 was used to assess emotional and behavioral problems. Compared with the control group, children with headache complaints showed more discomfort, which is the amount of negative affect induced by the sensory qualities of stimulation, including intensity, rate, or complexity of light, movement, sound, texture, or a combination of these modes of stimuli. These children also had higher scores for externalizing and internalizing emotional and behavioral problems compared to children without headaches. These findings show that the preschool-aged children with headaches presented more emotional and behavioral problems than the control group.

Gender differences of cognitive function in migraine patients: evidence from event-related potentials using the oddball paradigm. J Headache Pain 2014; 15:6.

Abstract
BACKGROUND Migraine shows gender-specific incidence and has a higher prevalence in females. Gender plays an important role in the prevalence of migraine, but few studies have investigated the effect of gender on the cognitive functions of migraine patients. This study investigated gender differences in the cognitive function of migraine patients without aura. METHODS We recruited 29 migraine patients (15 females; mean age 25.4 y) during the interictal period and 28 healthy age-matched participants (14 females; mean age 24.8 y). We used an auditory oddball paradigm to analyze target processing using event-related potentials. RESULTS We investigated the N2 and P3 components. The P3 amplitude was decreased in patients compared with the control, and this reduction was not modulated by gender. These results of the P3 provided a new evidence for the dysfunction of cognitive function in migraine patients. The N2 amplitude was larger for male than female migraine patients, and this gender effect was not found in the control group. CONCLUSIONS These results of the P3 provided a new evidence for the dysfunction of cognitive function in migraine patients. And those of N2 may explain that male patients have the super-sensitivity of cerebral function relevant to the early target-selection and response preparation. Our findings emphasize the importance of considering gender when researching the cognitive function of migraine patients.

Abstract
BACKGROUND Recently, an increasing number of articles have appeared on central auditory processing disorders, but in the literature there is only one study that evaluated the possible correlation between migraine in the critical phase and central auditory processing. The aim of our study was to assess the correlation between auditory processing information and childhood primary headaches in the intercritical phase. METHODS This is an observational study. We enrolled 54 patients, 30 with primary headache (migraine and tension headache) and 24 normal controls, matched for sex and age. The mean age at first observation was 9 years 10 months; the duration of observational follow-up was 2 years. Both groups had normal audiological and neurological profiles, normal peripheral hearing acuity and normal cognitive and behavioral skills. We excluded patients who had undergone pharmacological prophylactic treatment for headaches in the 6 months preceding the study and subjects with a frequency of headache lower than one every two months. After enrolment, both groups were analyzed with a computerized test battery for Speech Perception Tests in silence and in noise background to assess speech perception disabilities. In addition, with a test battery of Speech Perception Tests, we compared patients with migraines and tension-type headaches. The non-parametric χ2 test, the Mann-Whitney U-test and the Wilcoxon signed ranks test were used for statistical analysis. P-values <0.05 were considered significant and STATA 10 software was used for statistical analyses. RESULTS Our results showed that patients with primary headache (migraine and tension-type headache), had a deficit of auditory processing in noisy background compared to control cases, but we found no significant differences when we compared patients with migraine and tension-type headache. CONCLUSIONS This is a work in progress and further studies are needed to assess the relationship between the impairment of auditory processing and primary headache, not only to improve the diagnostic approach to primary headache, but also to improve therapeutic intervention.

Abstract
Background Primary headaches and Learning difficulties are both common in the pediatric population. The goal of our study was to assess the prevalence of learning disabilities and attention deficit disorder in children and adolescents with migraine and tension type headaches. Methods Retrospective review of medical records of children and adolescents who presented with headache to the outpatient pediatric neurology clinics of Bnai-Zion Medical Center and Meyer Children’s Hospital, Haifa, during the years 2009–2010. Demographics, Headache type, attention deficit disorder (ADHD), learning disabilities and academic achievements were assessed. Results 243 patients met the inclusion criteria and were assessed: 135 (55.6%) females and 108 (44.4%) males. 44% were diagnosed with migraine (35.8% of the males, 64.2% of the females, p = 0.04), 47.7% were diagnosed with tension type headache (50.4% of the males, 49.6% of the females). Among patients presenting with headache for the first time, 24% were formerly diagnosed with learning disabilities and 28% were diagnosed with attention deficit disorder (ADHD). ADHD was more prevalent among patients with tension type headache when compared with patients with migraine (36.5% vs. 19.8%, p = 0.006). Poor to average school academic performance was more prevalent among children with tension type headache, whereas good to excellent academic performance was more prevalent among those with migraine. Conclusions Learning disabilities and ADHD are more common in children and adolescents who are referred for neurological assessment due to primary headaches than is described in the general pediatric population. There is an association between headache diagnosis and school achievements.

Abstract
PURPOSE Epilepsy and migraine frequently show a clinical overlap. An increase in number of electroencephalographic abnormalities, such as centro-temporal spikes (CTS), may be observed in patients suffering from migraine, epileptic abnormalities that are typically in benign epilepsy of childhood with CTS (BECTS). The aim of this study is to better define the role of CTS in children with migraine compared to children with BECTS, in relation with their neuropsychological profile. METHODS Thirty-two children were enrolled and divided into three groups on the basis of their diagnosis: 16 children (eight males and eight females, aged 12.3 ± 2.58 years) affected by BECTS, 8 patients (four males and four females, aged 11.8 ± 3.47 years) affected by BECTS and migraine, and 8 children (four males and four females, aged 13.5 ± 1.79 years) affected by migraine showing CTS abnormalities. A cognitive and neuropsychological assessment was performed, using Wechsler Intelligence Scale for Children-third edition and NEPSY II, in all patients. RESULTS AND CONCLUSIONS A similar neuropsychological impairment was found in patients affected by BECTS and in those affected by BECTS and migraine; a significant deficit in short- and long-term verbal memory was evident in patients affected by migraine and CTS. CTS in patients with migraine can influence the neuropsychological tests, with a possible negative impact on language and learning development.

Psychophysiological mechanisms underlying spatial attention in children with primary headache. Brain Dev 2012; 34:640-7. [PMID: 22099868 DOI: 10.1016/j.braindev.2011.10.005] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2011] [Revised: 10/19/2011] [Accepted: 10/20/2011] [Indexed: 11/30/2022]
Abstract
OBJECTIVE Neurophysiological studies to evaluate spatial attention in children with primary headache are lacking. Tactile spatial attention modulates the N140 somatosensory evoked potential (SEP) amplitude. The aims of the study are: (1) to investigate the effect of spatial attention on the N140 amplitude in children with migraine and tension-type headache (TTH) and in healthy children, and (2) to correlate the neurophysiological results with a neuropsychological test for spatial attention. METHODS We studied 16 patients with migraine without aura (MoA), 12 TTH children and 10 healthy subjects. "Deux Barrage" test for spatial attention was administered. SEPs were recorded in a neutral condition (NC) and in a spatial attention condition (SAC). RESULTS No significant differences in neuropsychological measures were found between MoA, TTH and healthy subjects. The N140 amplitude increase during SAC, as compared to NC, was significantly higher in patients than in healthy controls. Migraineurs showed a positive correlation between the N140 amplitude increase during SAC and their neuropsychological performance. CONCLUSIONS Although spatial attention performances in children with headache are as good as in controls, the N140 amplitude increase during SAC in headache patients suggests that the psychophysiological mechanisms subtending spatial attention are different from those in healthy children.

Abstract
AIM We review the research literature examining neuropsychological performance in migraine. Findings were organized by neuropsychological construct assessed and results were reported using effect size conventions. Factors considered in explaining results included sample characteristics, migraine factors, and control for non-migraine variables. FINDINGS There is weak evidence for deficits in processing speed, attention, verbal memory, verbal skills, working memory, sustained attention, and inhibition in migraine relative to healthy controls. There are mixed results regarding deficits in visual memory, motor dexterity, visuospatial/constructional skills, visual reasoning, and mental flexibility in migraine relative to healthy controls. Mixed findings do not seem to be consistently related to study characteristics or presence of aura; other important migraine factors (such as migraine severity or presence of neuroradiological findings) remain understudied. Relative to non-healthy control groups, however, there is weak evidence for an effect of migraine in any cognitive domain. Longitudinal studies provide little evidence that neuropsychological functioning worsens over time in migraine or that migraine is a risk factor for Alzheimer's disease. RESEARCH IMPLICATIONS It remains possible that cognitive dysfunction is seen in only a subset of migraine sufferers, perhaps those with more severe illness or neurological involvement; however, more research is needed to examine this issue. Non-migraine differences among migraine sufferers, including medical and psychiatric comorbidities and variables associated with treatment seeking, may partially account for inconsistent findings and should be evaluated for in future research. CLINICAL IMPLICATIONS Clinicians should refer migraine patients for comprehensive neuropsychological evaluation only when there is sufficient evidence for concern. Such evaluations should include consideration of other psychological, neurological, and medical contributors to both migraine and cognitive status.

Abstract
OBJECTIVE The previous studies reporting consistent visual reaction times slowing in patients with migraine prompted us to verify if headache could be associated to a broader impairment of attention. This study aims to undertake a thorough investigation of attentional performance by extending the evaluation to children with primary headache of different types. METHODS We compared 62 children with headache (14 migraineurs with aura, 29 without aura and 19 with tension type headache) and 52 controls without headache, matched for age, sex, and intelligence using Conners' Continuous Performance Test. RESULTS The 3 clinical groups did not differ in attentional measures. The headache patients, collapsed in 1 single sample, had mean scores in Hit Reaction Time significantly different from those of controls and also had a higher percentage of atypical scores in 2 indices of the Conners' Continuous Performance Test (faster mean reaction time and more commissions). CONCLUSIONS Our results confirm the presence of an association between attentional problems and headache that may impact academic learning and daily activities on the long term. The finding that the 3 clinical groups did not show significant differences in attentional performance supports the hypothesis that migraine and tension headache form a continuum that may share the same pathophysiological mechanisms. These results are discussed considering that neurotransmitters and the cerebral circuits subserving headache, personality profile, and attention could overlap, thus predisposing these children to even mild attention malfunctioning.

Abstract
OBJECTIVE: Evaluate the cognitive functions of children with migraine and compare them to A control group. METHOD: 30 migraineur children and 30 control group children without migraine, age ranging from 8 to 12 years old, were subjected to a cognitive functions assessment with Wechsler Intelligence Scale for Children (WISCIII). RESULTS: Although both groups had a normal cognitive performance, children with migraine had significantly worse scores compared to the control group in the subtests of Information, Arithmetic, Vocabulary, Object Assembly and in the Indexes of Perceptual Organization, Resistance to Distraction and Processing Speed. CONCLUSION: Children with migraine had impairment in some cognitive functions such as attention, memory, information speed, and perceptual organization compared to the control group.

Abstract
PURPOSE To examine the adaptive functioning of children who underwent surgery for brain tumours with a view to analyse the related acute impairments and to describe their short-term outcome. METHOD We investigated adaptive functioning in 25 children (ranging from 2 to 18 years of age) for 40 days and again 3 and 6 months after they underwent surgery for various brain tumours. The Vineland Adaptive Behaviour Scales (VABS) were used to assess their adaptive functioning, considering the four main domains and all the subdomains. RESULTS The results remained stable over the follow-up period considered. The domain in which the scores were most severely affected was Daily Living, followed by the Socialisation and Communication domains. Within the Communication domain, the abilities investigated in the Receptive subdomain revealed the worst impairments. Within the Daily Living domain, impairments were most evident in the children's capacity to take care of themselves and handle domestic activities. In the Socialisation domain, Play and Leisure Time, and Interpersonal Relationships were the subdomains most severely impaired. CONCLUSIONS These findings are relevant because identifying children's adaptive functioning difficulties sooner could help their rehabilitation to be tailored and thus have a positive fallout on their long-term outcome.

Abstract
Migraine is a prominent cause of recurrent pain, affecting 12% of the population. In several case series, approximately 50% of migraineurs with aura were found to have patent foramen ovale (PFO). The pathophysiological mechanism is speculated to be passage of microemboli and vasoactive chemicals through the PFO, thereby evading pulmonary filtration and triggering migraine symptoms. This article presents the results of retrospective and prospective research studies documenting the effects of PFO closure on migraine symptoms and presents emerging theories on possible pathologic mechanisms that may partially explain the increased risk of ischemic stroke in the migraine population. Finally, evidence-based recommendations are presented for health care providers for managing patients who have migraine and PFO.

Cognitive effects of topiramate in migraine patients aged 12 through 17 years. Pediatr Neurol 2010; 42:187-95.

Abstract
Neuropsychologic data are presented from a randomized, double-blind, placebo-controlled, multicenter study with placebo, topiramate 50 mg/day, and topiramate 100 mg/day. The Cambridge Neuropsychological Test Automated Battery (CANTAB) and cognitive adverse events were used to evaluate neurocognitive effects of topiramate. Topiramate 100 mg/day vs placebo was associated with slight statistically significant score increases, indicating slowing, from baseline vs placebo in three CANTAB measures: five-choice reaction time (P = 0.028), pattern recognition memory mean correct latency (P = 0.027), and rapid visual information processing mean latency (P = 0.040). No other patterns related to topiramate treatment were observed in measurements of learning, memory, and visual information processing, except for potential improvement with topiramate 100 mg/day vs placebo in spatial span total errors (accuracy test) (P = 0.040). The most common cognitive and neuropsychiatric adverse events with a higher incidence in the topiramate 50 and 100 mg/day groups vs placebo were anorexia (9% and 11% vs 3%), insomnia (9% and 3% vs 3%), fatigue (6% and 9% vs 6%), and dizziness (6% and 9% vs 0%). Thus, topiramate 100 mg/day was associated with modest increases in psychomotor reaction times. Learning, memory, and executive function were unchanged. The tolerability profile, including cognitive adverse events, appeared to be acceptable.

Headache and cognitive profile in children: a cross-sectional controlled study. J Headache Pain 2009; 11:45-51.

Abstract
We investigated whether children affected by tension-type headache and migraine without aura, compared with a healthy control group that was matched by age, culturally and socioeconomically display a diverse intellectual functioning and have a separate “cognitive profile”. A cross-sectional study was conducted from January 2006 to November 2008 at “Sapienza University” in Rome. A total of 134 children were diagnosed as being affected by either migraine without aura (93) or tension-type headache (41). On the basis of our exclusion/inclusion criteria, we enrolled 82 of these 134 children, 63 of whom were affected by migraine without aura and 19 by tension-type headache. On entry, cognitive functions were assessed in both the affected subjects and the control group by the Wechsler Intelligence Scale for Children-revised. Significant differences were found between the headache and control groups in the mean total intelligence quotient and verbal intelligence quotient scores (p < 0.001). Significant negative correlations were found between the total intelligence quotient, verbal intelligence quotient, performance intelligence quotient and the frequency of attacks (r = −0.55 and p < 0.001, r = −0.61 and p < 0.001, r = −0.29 and p < 0.01, respectively), as well as between the total intelligence quotient score and the age at headache onset (r = 0.234, p < 0.05). Our results suggest that the cognitive profile of children affected by headache should be assessed at the first child neurology outpatient observation. From a therapeutic point of view, although within a normal range, the abilities most likely to be less brilliant in such children are verbal skills.

Abstract
The aim of this study was to evaluate the visual attention of children with migraine and compare it with a control group. Thirty migrainous children and 30 controls without headache were subjected to a visual attention assessment with Trail Making Tests (TMT) A/B, Letter Cancellation Test, and the Brazilian computerized test Visual Attention Test, third edition. The migraine group was evaluated after 2 days without headache. The migraine group had an inferior performance compared with the control group on TMT A ( P = 0.03) and B ( P = 0.001), and more errors on tasks 1 ( P = 0.032) and 2 ( P = 0.015) of the Visual Attention Test, presenting difficulty with selective and alternate attention. Attention is a neurological function that depends on structures such as the brainstem, cerebral cortex and the limbic system and on neurotransmitters such as dopamine and noradrenaline. The neurochemical aspects involved in the physiopathology of migraine and attention mechanisms probably predispose these children to visual attention deficits.

Abstract
Migraine is an independent risk factor for ischemic stroke, mainly in the subpopulation of women with migraine with aura who are younger than 45 years, particularly those that use estrogen containing oral contraceptives. Migraine however should be considered a benign condition as the absolute increase of stroke risk is small. Migraine is also associated with a high prevalence of cerebral white matter hyperintensities, occurring in the deep and periventricular white matter as well as infratentorial, mainly pontine. The pathogenesis and clinical significance of these hyperintensities is unclear. We do not know whether migraine may be considered a progressive disorder in a subset of patients because of accumulation of these hyperintensities over time. Studies on the relationship between migraine and cognitive functioning yielded conflicting results. Two recent studies have provided reassuring news for the migraine patient. A population-based twin study showed that a lifetime migraine diagnosis was not associated with cognitive deficits in middle-aged subjects. A long-term prospective study, assessing cognitive and memory changes in ageing individuals with and without a history of migraine, showed that migraineurs do not exhibit more decline on cognitive tests over time versus controls. Migraine is certainly not a recognized risk factor for (vascular) dementia.

Abstract
We investigated a possible correlation between brain excitability in children with migraine and tension-type headache (TTH) and their behavioural symptomatology, assessed by using the Child Behaviour Checklist (CBCL). The mismatch negativity (MMN) and P300 response were recorded in three successive blocks to test the amplitude reduction of each response from the first to the third block (habituation). MMN and P300 habituation was significantly lower in migraineurs and TTH children than in control subjects (two-way ANOVA: P < 0.05). In migraineurs, but not in TTH patients, significant positive correlations between the P300 habituation deficit and the CBCL scores were found ( P < 0.05), meaning that the migraineurs with the most reduced habituation showed also the worst behavioural symptomatology. To the best of our knowledge, this is the first study showing a correlation between neurophysiological abnormality and emotional symptomatology in migraine, suggesting a role of the latter in producing the migrainous phenotype.

Abstract
Migraine is an episodic headache disorder affecting as many as 10% of people worldwide. Familial hemiplegic migraine (FHM) is an autosomal dominant subtype of severe migraine accompanied by visual disturbances known as aura. Migrainous aura is caused by cortical spreading depression (CSD) - a slowly advancing wave of tissue depolarization in the cortex. More than half of FHM cases are caused by mutations in the CACNA1A gene, which encodes a neuronal Cav2.1 Ca2+ channel, resulting in increased Ca2+ flow into dendrites and excessive release of the excitatory neurotransmitter glutamate. In this issue of the JCI, Eikermann-Haerter et al. show that transgenic mice with FHM-associated mutations in Cacna1a have increased susceptibility to CSD compared with wild-type animals, likely due to augmentation of excitatory neurotransmission (see the related article beginning on page 99). Additional as-yet-undefined channel mutations may similarly render the migraine brain more susceptible to the initiation of CSD, with implications not only for the genesis of migraine but also for the hypoxic injury that accompanies its worst manifestation, complicated migraine.

Abstract
Psychiatric disorders, notably mood and anxiety disorders, are frequently associated with migraine and chronic daily headaches. The obsessive-compulsive disorder (OCD) is included in the spectrum of anxiety disorders and may be a comorbid condition in headache patients. However, little information has been reported in the literature about this association. This is an important issue as OCD may contribute to the development or maintenance of treatment-resistant chronic headaches. In this paper, we describe a young female patient with refractory chronic migraine and OCD. Considerations on diagnosis, management and treatment of these comorbid conditions are presented.

Abstract
Cortical spreading depression (CSD) is a self-propagating wave of cellular depolarization that has been implicated in migraine and in progressive neuronal injury after stroke and head trauma. Using two-photon microscopic NADH imaging and oxygen sensor microelectrodes in live mouse cortex, we find that CSD is linked to severe hypoxia and marked neuronal swelling that can last up to several minutes. Changes in dendritic structures and loss of spines during CSD are comparable to those during anoxic depolarization. Increasing O2 availability shortens the duration of CSD and improves local redox state. Our results indicate that tissue hypoxia associated with CSD is caused by a transient increase in O2 demand exceeding vascular O2 supply.
