Association between Body Mass Index and Migraine

European Neurology (2010)

José Francisco Téllez‐Zenteno Dave Rishi Pahwa Lizbeth Hernández‐Ronquillo Guillermo García‐Ramos Antonio Velázquez

Objective: To explore the prevalence of overweight and obesity in patients with migraine. Background: Previous studies support the concept that obesity is an exacerbating factor for migraine. Also, some studies have found an increased frequency of obesity and overweight in migraine patients compared to the normal population. Methods: We studied 1,371 patients with migraine and 612 controls. The migraine population was matched by gender with a healthy control group. Results: Mean age of patients with migraine was 38.0 ± 13.3 years and in the controls it was 34.8 ± 12.1 years. The percentage of females in both groups was similar (migraine 81.6% vs. control 83.3%, p = 0.40). The distribution of body mass index (BMI) in migraine patients and controls was as follows: underweight patients (BMI <18.5) 3.1% migraine versus controls 1.5%; normal (BMI 18.5–24.9) 44.8% migraine versus controls 47.1%; overweight (BMI 25–29.9) 38.3% migraine versus controls 33.7%; obese (BMI 30–34.5) 10.3% migraine versus controls 13.6%; morbidly obese (BMI 35) 3.4% migraine versus controls 4.2%. Overweight and obesity in migraine patients versus controls were statistically significant. No association was found between the disability and severity of migraine and BMI. Conclusions: This study did not find associations between severity or disability of migraine and BMI.

Demographic, clinical and comorbidity data in a large sample of 1147 patients with migraine in Mexico City

The Journal of Headache and Pain (2005)

José Francisco Téllez‐Zenteno Guillermo García‐Ramos F. Zermeño–Pöhls A Velázquez

The objective was to identify the sociodemographic and clinical characteristics of a large sample of patients with migraine in Mexico City. This cross–sectional study was performed in two tertiary centers in Mexico City and affiliated hospitals. We evaluated the presence of migraine through a standardised interview according to the criteria of the International Headache Society. We studied 1147 patients. The mean age was 37.1±13.6 (6–77) years. Nine hundred and twenty one patients were female (80%). The age of onset of migraine was 19.4±10.3 (1–69) years. Six hundred and four patients had migraine with aura (53%) and 543 without aura (47%). The female/male ratio was 4:1. One hundred and forty–seven patients had cardiovascular problems (13%), 72 had neurological problems (6%), 233 had gastrointestinal problems (20%) and 323 had psychiatric problems (28%). In this study we described the clinical characteristics of a large sample of patients with migraine in Mexico City. Our sample has similar characteristics to other countries.

[Injuries, accidents and mortality in epilepsy: a review of its prevalence risk factors and prevention].

PubMed (2011)

José Francisco Téllez‐Zenteno Rita Nguyen Lizbeth Hernádez-Ronquillo

Currently, there is intense clinical research into various aspects of the medical risks relating to epilepsy, including total and cause-specific mortality, accidents and injuries in patients with epilepsy and mortality related with seizures. Submersion injuries, motor vehicle accidents, burns, and head injuries are among the most feared epilepsy-related injuries. Published risk factors for injuries include the number of antiepileptic drugs, history of generalized seizures, and seizure frequency. In general, studies focusing on populations with more severe forms of epilepsy tend to report substantially higher risks of injuries than those involving less selected populations. On the other hand, studies based in non selected populations of people with epilepsy have not shown an increase frequency of injuries in people with epilepsy compared with the general population. Some studies have shown that patients with epilepsy are more frequently admitted to the hospital following an injury. Possible explanations include are more cautious attitude of clinicians toward injuries occurring in the setting of seizures; hospitalization required because of seizures and not to the injuries themselves; and hospitalization driven by other issues, such as comorbidities, which are highly prevalent in patients with epilepsy. This article reviews information about specific type of injuries such as fractures, burns, concussions, dislocations, etc. Finally this article review in a comprehensive way information of mortality in patients with epilepsy. Aspects of mortality discussed in this review are: epidemiology, causes of mortality, sudden death in epilepsy and prevention measures.

Bilateral hippocampal stimulation for intractable temporal lobe epilepsy: Impact on seizures and memory

Epilepsia (2009)

Richard S. McLachlan Susan Pigott José Francisco Téllez‐Zenteno Samuel Wiebe Andrew G. Parrent

The effect of continuous electrical stimulation of the hippocampus bilaterally on seizures and memory was assessed in two subjects with seizures from both mesial temporal lobes who were not candidates for resective epilepsy surgery. A double blind, randomized, controlled, cross-over trial design was utilized. Two electrodes with four contacts each were implanted along the axis of the hippocampus bilaterally. Simultaneous stimulation of all electrodes contacts was either on or off during each 3-month interval. Seizure frequency decreased by 33% in the two patients during stimulation and remained lower by 25% for the 3 months after stimulation was turned off before returning to baseline (p < 0.01). No consistent change in objective or subjective measures of memory occurred. No other adverse effects occurred. Seizure frequency is reduced both during and for a period after bilateral hippocampal stimulation, but the overall impact in this study is not as robust as has been previously reported.

Discontinuation of antiepileptic drugs after successful surgery: who and when?

Epileptic Disorders (2012)

José Francisco Téllez‐Zenteno Lizbeth Hernández‐Ronquillo Farzad Moien‐Afshari

Surgery is a highly effective treatment for some specific types of refractory epilepsy and once seizure freedom is achieved many patients and clinicians have to ponder whether to taper or discontinue antiepileptic drugs (AEDs). However, there is no standard practice or guidelines and practices vary widely. The few studies that have addressed this question are retrospective and lack randomised, controlled comparisons, making it difficult to draw any solid inferences. This review examines this topic by analysing key data based on the following: controlled studies which compare outcomes in patients with either withdrawn or unmodified AEDs after epilepsy surgery, non-controlled studies, information from meta-analyses and systematic reviews, surveys of clinical practice, and other relevant reviews. Between 12 and 32% of patients had seizure relapse following tapering or discontinuation of AEDs, which was not significantly different from 7 to 45% in patients without AED modification. In the event of seizure relapse upon tapering of AEDs, 45-92.3% restarted AED treatment and regained seizure freedom. The most consistent risk factors for seizure relapse were: age older than 30 years at the time of surgery, persistent auras, early drug tapering, seizure recurrence before a reduction of drugs, normal MRI, a longer period with epilepsy, absence of hippocampal sclerosis, and the presence of interictal discharges on EEG after surgery.
