Non-pharmacologic and Mindful-Based Approaches for Pediatric Headache Disorders: a Review.

PURPOSE OF REVIEW: Headache disorders in children and adolescents are common. Among the different headache disorders, migraine and tension headache are highly prevalent and often debilitating. Pharmacological treatments for pediatric patients are often not approved or effective. Practice guidelines for prevention of pediatric headache and migraine are now incorporating information and recommendations regarding non-pharmacologic therapeutic options. Understanding the mechanism of action, safety, and efficacy of the non-pharmacologic as well as mindful-based therapeutic alternatives currently available for the management and treatment of headache and migraine may allow additional treatment alternatives for children with these conditions. RECENT FINDINGS: Studies have been published looking at non-pharmacologic treatments, and mindful-based approaches, namely relaxation, mindfulness meditation, yoga, and hypnosis as options for the treatment of headache and migraine, although there are few that examine these in children and adolescents. Several recent studies that have relevance to the care of children with headache and migraine are reviewed. Non-pharmacologic and mindful-based approaches for the prevention and treatment of headache and migraine in children show safety and efficacy data that is promising. Consider incorporating these multi-modal approaches into the therapeutic management strategies for the child or adolescent with headache and migraine. Additional prospective studies and/or randomized-controlled trials are necessary to further assess the efficacy and cost-effectiveness of these methods.

Surgical resection of hypothalamic hamartomas for severe behavioral symptoms.

Hypothalamic hamartomas (HHs) are associated with treatment-resistant epilepsy. Many patients also experience severe and sometimes disabling psychiatric problems. The most common behavioral symptoms consist of paroxysms of uncontrolled anger related to poor frustration tolerance. These can include violence, resulting in disrupted family or school relationships, and legal consequences including incarceration. In a large cohort of patients undergoing surgical resection of HHs for refractory epilepsy, 88% of families described an improvement in overall behavioral functioning [1]. Here, we describe four patients (three males, mean age=11.9 years) who underwent surgical resection of HHs largely for behavioral indications. Three patients had relatively well controlled seizures, and one had no history of epilepsy. All patients had striking improvement in their psychiatric comorbidity. HH resection can result in significant improvement in behavioral functioning, even in patients with relatively infrequent seizures. Further investigation under approved human research protocols is warranted.

Dissolving oral clonazepam wafers in the acute treatment of prolonged seizures.

Klonopin (clonazepam; Genentech Inc, South San Francisco, California) oral wafers are benzodiazepines with anticonvulsive and anxiolytic properties. Our institution has been prescribing clonazepam wafers for acute treatment of prolonged seizures for years. Patients' size determined dosing at 0.25, 0.5, 1, or 2 mg wafers. We proceeded to obtain evidence for efficacy. Hospital Institutional Review Board approval was obtained for anonymous patient survey. All children who had been prescribed clonazepam wafers over a 6-year period at our institution were mailed detailed questionnaires. Three hundred eighty-one questionnaires were mailed with 88 replies but only 56 with meaningful data. Average age was 12.1 years. There were 31 males. Efficacy was defined as stopping seizure within 10 minutes, >50% of the time. Thirty-eight of the 56 (68%) patients met this criterion. From these 38 patients, 19 (50%) had seizures stop within 1 minute. Overall results were comparable to Diastat (rectal diazepam; Valeant Pharmaceuticals International, Aliso Viejo, California). Clonazepam wafers are an effective acute therapy for prolonged seizures.

Intravenous levetiracetam in children with seizures: a prospective safety study.

In 2006, intravenous levetiracetam received US Food and Drug Administration (FDA) approval for adjunctive treatment of partial onset seizures in adults with epilepsy, 16 years or older. We have established the safety, tolerability, and dosage of intravenous levetiracetam in children. This prospective study included 30 children (6 months to <15 years of age). Patients were administered a single dose of intravenous levetiracetam (50 mg/kg, maximal dose 2500 mg) over 15 minutes. A blood level of levetiracetam was performed 10 minutes after the infusion. The treated children's average age was 6.3 years (range 0.5-14.8 years). The mean levetiracetam level was 83.3 microg/mL (range 47-128 microg/mL). There were no serious adverse reactions. Minor reactions included sleepiness, fatigue, and restlessness. An apparent decrease in seizure frequency across all seizure types was noted. The dose of 50 mg/kg was well tolerated by the patients and is a safe, appropriate loading dose.
