RESUMO
In Canada, recreational use of cannabis was legalized in October 2018. This policy change along with recent publications evaluating the efficacy of cannabis for the medical treatment of epilepsy and media awareness about its use have increased the public interest about this agent. The Canadian League Against Epilepsy Medical Therapeutics Committee, along with a multidisciplinary group of experts and Canadian Epilepsy Alliance representatives, has developed a position statement about the use of medical cannabis for epilepsy. This article addresses the current Canadian legal framework, recent publications about its efficacy and safety profile, and our understanding of the clinical issues that should be considered when contemplating cannabis use for medical purposes.
Énoncé de position quant à l'utilisation du cannabis médical dans le traitement de l'épilepsie. L'utilisation du cannabis à des fins récréatives a été légalisée au Canada en octobre 2018. Parallèlement à ce changement de politique, de récentes publication visant à évaluer l'efficacité du cannabis dans le traitement de l'épilepsie, de même qu'une sensibilisation médiatique accrue en ce qui concerne son utilisation, ont eu pour effet d'augmenter l'intérêt du grand public à son égard. Le Comité médical thérapeutique de la Ligue canadienne contre l'épilepsie (LCCE), de concert avec un groupe multidisciplinaire d'experts et des représentants de l'Alliance canadienne de l'épilepsie, a ainsi élaboré un énoncé de position en ce qui regarde l'utilisation du cannabis médical dans le traitement de l'épilepsie. Cet article entend donc aborder le cadre légal qui prévaut actuellement au Canada et examiner de récentes publications s'étant penchées sur le profil sécuritaire et sur l'efficacité du cannabis. De plus, nous voulons apporter un éclairage au sujet des aspects cliniques dont il faudrait tenir compte au moment d'envisager l'utilisation du cannabis à des fins médicales.

BACKGROUND: Children and youth with epilepsy have long been subjected to excessive restrictions on extracurricular activities due to concerns over risk of injury. Over time physicians and medical regulatory associations have liberalized the advice given for people with epilepsy to promote independence, self-esteem and general health benefits of physical activity. Current evidence suggests that few restrictions are needed for children with epilepsy beyond water-related precautions and avoidance of very high-risk activities. However, more stringent restrictions on daily activities may be imposed by caregivers. This study was aimed at exploring current perceptions of parents regarding restrictions on activity for children with epilepsy and the child's perspective on restrictions related to the diagnosis. METHODS: A self-administered questionnaire was offered to a sample of parent-child dyads of children/youth with epilepsy attending summer camp for children with epilepsy age 8-18years. A 10-item validated HARCES Parent Scale of Childhood Epilepsy was completed by the parent/guardian and a modified-HARCES completed by the child. The primary objective was to assess the degree of restrictions placed on children with epilepsy from the perspective of child and parent assessed independently. Agreement of perceived restrictions between parent-child dyads was also determined. RESULTS: 21 parent/guardian-child pairs were recruited with mean age of children/youth 12.7years (range 9-16years). Total HARCES scores for parents and guardians ranged from 11-26 (x=16.5; SD 4.9) while total scores for children with epilepsy similarly ranged from 10-25 (x=15.2; SD 4.9). There were no differences in total parent scores when analyzed by child's age (<13 or >13years), gender, age of seizure onset, seizure frequency or seizure type. Total HARCES scores showed no agreement between parent and child pairs with correlation of 0.2798 (95% CI -0.173-0.635). CONCLUSIONS: Children and youth with epilepsy often face activity restrictions based on fear of perceived risk of injury. This small sample shows evidence that even more permissive parents and his/her children still feel limited by such restrictions. Parents and children do not perceive these restrictions in the same way despite similar education by physicians highlighting an important secondary role of epilepsy camps in targeting misperceptions and educating families on appropriate precautions.

PURPOSE: To compare the activity profiles of a nationally representative sample of individuals with epilepsy compared to the general population. METHODS: The Canadian Community Health Survey is a cross-sectional survey that uses a stratified cluster sample design to obtain information on Canadians 12 years of age or older. Data on activity and energy expenditure, among those aged 12-39 years, were compared for those who reported having epilepsy and the remainder of the population. RESULTS: Of the 53,552 respondents, 341 reported having epilepsy. There was no difference in the monthly frequency of leisure physical activity of >15 min duration between those who did and did not have epilepsy. The daily energy expenditure related to leisure physical activity was also similar between the two groups. The choice of leisure activity was similar, but those with epilepsy were more likely to use walking as a leisure physical activity and were less likely to be involved in ice hockey, weight training, and home exercise. DISCUSSION: These results suggest that the negative attitudes toward restricting access to physical activity do not appear to be adversely affecting the leisure activity of Canadian youth and young adults with epilepsy.

In adults, caffeine has been shown to enhance the effectiveness of most analgesics, including ibuprofen. This double-blind cross-over pilot study evaluated the effect of ibuprofen and caffeine compared with ibuprofen and placebo in 12 children with headaches. Patients completed diaries for both headaches. Outcome measures included a five-faces severity scale, a measure of clinical disability, and a scale of pain severity. Comparison of the cumulative response scores revealed a trend toward a greater response to ibuprofen-caffeine treatment of headaches (P = 0.14, P = 0.09, and P = 0.07 for the three measures, respectively). Further larger studies are needed to confirm this effect and to identify potential responders.

Polymicrogyria (PMG) is a heterogeneous malformation of cortical development characterized by excessive gyration and abnormal cortical lamination. Typically, bilateral forms have more severe developmental delay and early-onset epilepsy, but the full spectrum of severity remains ill-defined. We report two cases of right hemispheric PMG and neonatal-onset, drug-resistant seizures culminating in early death. Case 1 began having seizures on Day 1 of life that intensified in severity and proved resistant to numerous antiepileptic drugs. He underwent right functional hemispherectomy but died three weeks post-operatively due to ongoing seizures. Case 2 presented with seizures on Day 3 of life and required respiratory support for prolonged ictal apnoeas. Seizures were resistant to antiepileptic drugs and eventually led to respiratory arrest, once aggressive resuscitative measures were withdrawn. In both cases, seizures seemingly originated independently in both hemispheres. These cases represent a severe phenotype of unilateral hemispheric PMG with bilateral seizures.

Headaches are an extremely common complaint encountered in the pediatric population. The headache history establishes the diagnosis in the vast majority and most importantly identifies features suggesting a secondary cause. The headache history outlined will aid in headache classification and screen for ominous causes. A comprehensive headache examination is aimed at excluding secondary causes. Headaches resulting from serious organic causes are virtually always associated with neurologic signs at the time of presentation. Investigations are not routinely required for pediatric headache, but neuroimaging should be strongly considered in children with an abnormal neurologic examination or history worrisome for intracranial pathology. The management approach for children with primary headaches should focus on reassurance and education. Developing an individualized therapeutic strategy requires knowledge of the child's headache-related disability and impact on quality of life. Treatment should begin with a nonpharmacologic approach, which influences lifelong prevention and management of headaches. Pharmacologic interventions target both acute symptomatic treatment and prophylactic medications. Preventative treatment may be beneficial when headaches result in significant disability and impaired quality of life. The limited available evidence for prophylactic treatment options is reviewed. Research into pediatric headache prevention and management remains a priority given the potential lifelong morbidity associated with headache.

Data was analyzed from the nationally representative Canadian Community Health Survey. A total of 17,549 adolescents reported whether they had "migraine headaches" (response rate 99.9%) and in what exercise activities they participated. Those with migraine reported more daily activity than migraine-free peers when corrected for age and sex. They were as likely to play contact sports but were more involved in other noncompetitive activities, such as walking (P<0.001), gardening and yard work (P=0.008), jogging and running (P=0.002), and fishing (P=0.03). Canadian adolescents with migraine are therefore overall more active than their peers without migraine.

Familial paroxysmal nonkinesigenic dyskinesia (Mount and Reback syndrome) is characterized by episodes of dystonia and chorea, which are precipitated by fatigue, emotional stress, alcohol, or foods. We report two children from a large kindred with this condition who responded to sublingual lorazepam.

BACKGROUND: Although headaches in childhood are common, there are few data available on their long-term prognosis. We have monitored a group of patients since diagnosis in 1983. METHODS: Patients who were part of the 20-year follow-up study in 2003 were contacted, and data were collected using a standardized telephone interview. Details of headache characteristics and identified precipitants and alleviating factors were gathered. The most effective means of controlling the headaches were also recorded. RESULTS: Follow-up was achieved for 28 of 60 patients (47%). Over the 30 years since diagnosis, eight patients (29%) reported a complete resolution of headaches, including three whose headaches resolved between the 20- and 30-year follow-up studies. The type of headache varied over the 30-year time interval with only three patients maintaining the same headache type at all four time periods of 1983, 1993, 2003, and 2013. Only one patient used prescription medication as the primary method for controlling headaches. The most commonly used intervention was nonprescription analgesia, self-relaxation and/or hypnosis, and precipitant avoidance. CONCLUSIONS: Headaches persist in approximately 70% of children 30 years after diagnosis. Encouraging children to manage their headaches with simple analgesia and precipitant avoidance appears to have long-term benefits.

BACKGROUND: The International Classification of Headache Disorders-III beta includes a number of episodic syndromes associated with migraine. Those who treat pediatric headaches are aware of a number of other phenomena (such as the Alice in Wonderland syndrome) which are thought to occur as precursors of migraine. There is no available data on the course of these phenomena over the decades following childhood headache diagnosis. METHODS: Patients who were observed by one of the authors in 1983 were contacted by telephone in 1993, 2003, and 2013. Details were gathered regarding the presence and characteristics of ongoing headaches and about the presence of sleepwalking, motion sickness, and distortions of either time or space perceptions. RESULTS: Twenty-eight patients were monitored in 1993, 2003, and 2013. Ongoing headaches were reported by 71%. Sleepwalking was only present in one patient in 2013. More than a third still complained of motion sickness, and more than one quarter still experienced distortions of time. Distortions of space were still reported by nearly 20%. Reporting any of these phenomena was not consistent over time, with some patients reporting distortions for the first time in adulthood. There was no clear correlation with migraine, and patients with tension-type headaches also reported the phenomena. CONCLUSIONS: Motion sickness and distortions of both space and time persist into the fifth decade for many patients initially observed with headaches in childhood. The correlation with migraine is less clear than previously thought.

Understanding what patients and their parents want is essential to plan appropriate patient-centered care. Questionnaires were distributed to 500 consecutive children and parents seen for their first pediatric neurology consultation. Both patients and their families answered questions about their expectations of the consultation, their level of worry, and the Penn State Worry Questionnaire. The 5 most important issues for the parents were to get information, to work with the doctor to manage the problem, to have questions answered, to find out what was wrong, and to discuss the impact on the child's life. The children had very similar priorities. The 5 least important concerns for parents were to get a prescription, blood tests, to talk to others with similar problems, to get a radiograph/computed tomography/magnetic resonance imaging (MRI) and to be told nothing is wrong. The pediatric neurologists did well in anticipating these priorities but had more difficulty appreciating parent and patient level of worry.
