Acute Treatment of Migraine: Expert Consensus Statements from the United Arab Emirates (UAE)

INTRODUCTION

Migraine, characterized by recurrent headaches and often accompanied by other symptoms like nausea, vomiting, and sensitivity to light and sound, significantly impacts patients' quality of life (QoL) and daily functioning. The global burden of migraines is reflected not only in terms of reduced QoL but also in the form of increased healthcare costs and missed work or school days. While UAE (United Arab Emirates)-specific consensus-based recommendations for the effective use of preventive calcitonin gene-related peptide (CGRP)-based migraine therapies have been published previously, an absence of such regional guidance on the management of acute migraine represents a gap that needs to be urgently addressed.

METHODS

A task force of eight neurologists from the UAE with expertise in migraine management conducted a comprehensive literature search and developed a set of expert statements on the management of acute migraine that were specific to the UAE context. To ensure diverse perspectives are considered, a Delphi panel comprising 16 neurologists plus the task force members was set up. Consensus was achieved using a modified Delphi survey method. Consensus was predefined as a median rating of 7 or higher without discordance (if > 25% of the Delphi panelists rate an expert statement as 3 or lower on the Likert scale). Expert statements achieving consensus were adopted.

RESULTS

The Modified Delphi method was used successfully to achieve consensus on all nine expert statements drafted by the task force. These consensus statements aim to provide a comprehensive guide for UAE healthcare professionals in treating acute migraine. The statements cover all aspects of acute migraine treatment, including what goals to set, the timing of treatment, treatment strategy to use in case of inadequate response to triptans, safety aspects of combining gepants for acute attacks with preventive CGRP-based therapies, special population (pregnant and pediatric patients) considerations, and the management of the most bothersome symptoms (MBS).

CONCLUSIONS

Adopting these consensus statements on the treatment of acute migraine can help enhance patient care, improve outcomes, and standardize treatment practices in the UAE. The collaborative effort of experts with diverse experiences in developing these consensus statements will strengthen the credibility and applicability of these statements to various healthcare settings in the country.

Safety and Tolerability of Combining CGRP Monoclonal Antibodies with Gepants in Patients with Migraine: A Retrospective Study

INTRODUCTION

The introduction of clacitonin gene-related peptide (CGRP) monoclonal antibodies (mAbs) has revolutionized the treatment of migraines. In clinical practice gepants might be considered as a valid option to treat acute attacks in patients with migraine who are treated with mAbs. However, the safety and tolerability of such a combination is not well addressed in the real-world setting. We designed this study to evaluate the safety and tolerability of combining CGRP mAbs with gepants in the management of migraines.

METHODS

This was a retrospective, real-world, exploratory study. The participants included within the study were adult (≥ 18 years) patients diagnosed with migraine. Screening for patients who were treated with at least one GCRP mAbs was done. Data was collected from one site, the American Center for Psychiatry and Neurology, Abu Dhabi UAE. A total of 516 patients taking CGRP mAbs were identified. Extracted data from patients' electronic medical records included patient demographics, migraine characteristics, prescribed treatments, and adverse events (AEs). The tolerability and safety of the combination therapy was evaluated on the basis of documented AEs.

RESULTS

Among the identified 516 patients, 234 were administered gepants in addition to the CRGP mAb (215, rimegepant; 19, ubrogepant). Eleven of the 234 patients switched from rimegepant to urogepant as a result of lack of efficacy; one patient switched from urogepant to zolmitriptan because of the lack of insurance coverage of the former medication. Among all the patients included in this study, three AEs were documented. These AEs were generally mild and transient and hence did not lead to discontinuation of treatment. Moreover, 42 of the 234 (17.9%) patients were switched from one class of CGRP mAbs to another at least once while continuing treatment with the assigned gepants.

CONCLUSION

The findings of this study demonstrate that combining CGRP mAbs with gepants is a safe and well-tolerated treatment approach for migraine. Future studies are warranted to further validate these findings and explore long-term outcomes.

Effectiveness of Switching CGRP Monoclonal Antibodies in Non-Responder Patients in the UAE: A Retrospective Study

Calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs) have shown promising effectiveness in migraine management compared to other preventative treatment options. Many questions remain regarding switching between antibody classes as a treatment option in patients with migraine headaches. This preliminary retrospective real-world study explored the treatment response of patients who switched between CGRP mAb classes due to lack of efficacy or poor tolerability. A total of 53 patients with migraine headache switched between three of the CGRP mAbs types due to lack of efficacy of the original prescribed CGRP mAbs, specifically eptinezumab, erenumab, and galcanezumab. Fremanezumab was not included due to unavailability in the UAE. Galcanezumab and eptinezumab target the CGRP ligand (CGRP/L), while erenumab targets CGRP receptors (CGRP/R). The analysis of efficacy demonstrated that some improvements were seen in both class switch cohorts (CGRP/R to CGRP/L and CGRP/L to CGRP/R). The safety of switching between CGRP classes was well observed, as any adverse events presented before the class switch did not lead to the discontinuation of treatment following the later switch. The findings of this study suggest that switching between different classes of CGRP mAbs is a potentially safe and clinically viable practice that may have some applications for those experiencing side effects on their current CGRP mAb or those witnessing suboptimal response.

Consensus-Based Recommendations on the Use of CGRP-Based Therapies for Migraine Prevention in the UAE

INTRODUCTION

Migraine is a common debilitating neurological disorder affecting a large proportion of the general population. Calcitonin gene-related peptide (CGRP), a 37-amino acid neuropeptide, plays a key role in the pathophysiology of migraine, and the development of therapies targeting the anti-CGRP pathway has revolutionized the field of migraine treatment.

METHODS

An expert task force of neurologists in the United Arab Emirates (UAE) developed and critically assessed recommendations on the use of CGRP-based therapies in migraine treatment and management in the UAE, based on available published literature. A consensus was reached for each statement by means of an open-voting process, based on a predefined agreement level of at least 60%.

RESULTS

The consensus recommendations advocate the need for guidelines for the appropriate use of CGRP-based therapies by defining patient cohorts and appropriate monitoring of therapeutic response as well as standardizing the initiation, assessment, and cessation of treatment. The consensus recommendations were primarily formulated on the basis of international studies, because of the limited availability of regional and local data. As such, they may also act as guidelines for global healthcare providers.

CONCLUSIONS

These are the first consensus recommendations for the UAE that address the use of CGRP-based therapies in the treatment and management of migraine, integrating both clinical evidence and medical expertise to enhance clinical judgment and decision-making.

Effectiveness and Safety of Eptinezumab in Episodic and Chronic Migraine Headache in the UAE: A Retrospective Study

INTRODUCTION

Eptinezumab is a humanized IgG1 immunoglobulin monoclonal antibody administered intravenously as a preventative migraine treatment. Previously conducted randomized, double-blind, placebo-controlled trials exhibited significant reductions in monthly migraine frequency among adults experiencing episodic and chronic migraine. The present study seeks to expand upon the current findings and to evaluate eptinezumab's efficacy as a preventative treatment for chronic and episodic migraine patients in the United Arab Emirates. This study is intended to represent the first real-world evidence and will hopefully serve as a valuable complement to the existing literature on the subject.

METHODS

This was a retrospective exploratory study. The participants included within the study were adult (≥ 18 years) patients diagnosed with either episodic or chronic migraine. Patients were categorized according to their history of previous preventative treatment failure. For the final assessment of treatment efficacy, we included only patients with a minimum of 6 months of clinical follow-up data. Patients were assessed at baseline for their monthly migraine frequency and assessed again at months 3 and 6. The primary objective was to evaluate the efficacy of eptinezumab in reducing migraine frequency among chronic and episodic migraine patients.

RESULTS

A total of 100 participants were identified, of whom 53 completed the study protocol at month 6. Of the total, 40 (75.47%) were female, 46 (86.79%) were Emirati locals, and 16 (30.19%) were pharmaceutically naïve, having never tried any prior preventative therapy. Additionally, 25 (47.17%) patients met the criteria for chronic migraine (CM), whereas the remaining 28 (52.83%) were diagnosed with episodic migraine (EM). The baseline monthly migraine frequency (MMD) was 12.23 (4.97) days across all participants, 15.56 (3.97) for CM patients, and 9.25 (3.76) for EM patients; by month 6, these frequencies reduced to 3.66 (4.21), 4.76 (5.32), and 2.68 (2.61), respectively. Overall, 58.49% of those enrolled experienced > 75% reduction in MMD frequency by month 6.

CONCLUSION

Patients enrolled in this trial experienced clinically significant reductions in MMD by month 6. Eptinezumab was well tolerated and with one AE of significance that led to discontinuation from the study.

Multicentre Observational Study of Treatment Satisfaction with Cladribine Tablets in the Management of Relapsing Multiple Sclerosis in the Arabian Gulf: The CLUE Study

INTRODUCTION

Inconvenient administration and side effects of some disease-modifying therapies (DMTs) for relapsing multiple sclerosis (RMS) can deter adherence. We evaluated treatment satisfaction with cladribine tablets (CladT) for RMS in the Arabian Gulf.

METHODS

This was a non-interventional, multicentre, prospective observational study in non-pregnant/lactating adults (aged ≥ 18 years) with RMS eligible for 1st treatment with CladT (EU labelling). The primary outcome was overall treatment satisfaction at 6 months (Treatment Satisfaction Questionnaire for Medication [TSQM]-14, v. 1.4), Global Satisfaction subscale. Secondary endpoints were TSQM-14 scores for convenience, satisfaction with side effects and satisfaction with effectiveness. Patients provided written informed consent.

RESULTS

Of 63 patients screened, 58 received CladT and 55 completed the study. Mean age was 33 ± 9 years; mean weight 73 ± 17 kg; 31% male/69% female; mostly from the United Arab Emirates (52%) or Kuwait (30%). All had RMS (mean 0.9 ± 1.1 relapses in the past year), mean Expanded Disability Status Scale (EDSS) 1.4 ± 1.2; 36% were DMT-naïve. Mean [95% CI] score was high for overall treatment satisfaction (77.8 [73.0-82.6]), ease of use (87.4 [83.7-91.0]), tolerability (94.2 [91.0-97.3]) and effectiveness (76.2 [71.6-80.7]). Scores were similar irrespective of DMT history, age, gender, relapse history or EDSS. No relapses or serious treatment-emergent adverse events (TEAE) occurred. Two severe TEAE occurred (fatigue, headache) and 16% reported lymphopenia (two cases of grade 3 lymphopenia). Absolute lymphocyte counts at baseline and 6 months were 2.2 ± 0.8 × 109/L and 1.3 ± 0.3 × 109/L, respectively.

CONCLUSIONS

Treatment satisfaction, ease of use, tolerability and patient-perceived effectiveness for CladT were high, irrespective of baseline demographics, disease characteristics and prior treatment.

Perampanel for the treatment of people with idiopathic generalized epilepsy in clinical practice

OBJECTIVE

This study was undertaken to evaluate perampanel (PER) when used under real-world conditions to treat people with idiopathic generalized epilepsy (IGE) included in the PERaMpanel pooled analysIs of effecTiveness and tolerability (PERMIT) study.

METHODS

The multinational, retrospective, pooled analysis PERMIT explored the use of PER in people with focal and generalized epilepsy treated in clinical practice across 17 countries. This subgroup analysis included PERMIT participants with IGE. Time points for retention and effectiveness measurements were 3, 6, and 12 months (last observation carried forward, defined as "last visit," was also applied to effectiveness). Effectiveness was evaluated by seizure type (total seizures, generalized tonic-clonic seizures [GTCS], myoclonic seizures, absence seizures) and included ≥50% responder rate and seizure freedom rate (defined as no seizures since at least the previous visit). Safety/tolerability was monitored throughout PER treatment and evaluated by documenting the incidence of adverse events (AEs), including psychiatric AEs and those leading to treatment discontinuation.

RESULTS

The Full Analysis Set included 544 people with IGE (51.9% women, mean age = 33.3 years, mean epilepsy duration = 18.1 years). At 3, 6, and 12 months, 92.4%, 85.5%, and 77.3% of participants were retained on PER treatment, respectively (Retention Population, n = 497). At the last visit, responder and seizure freedom rates were, respectively, 74.2% and 54.6% (total seizures), 81.2% and 61.5% (GTCS), 85.7% and 66.0% (myoclonic seizures), and 90.5% and 81.0% (absence seizures) (Effectiveness Population, n = 467). AEs occurred in 42.9% of patients and included irritability (9.6%), dizziness/vertigo (9.2%), and somnolence (6.3%) (Tolerability Population, n = 520). Treatment discontinuation due to AEs was 12.4% over 12 months.

SIGNIFICANCE

This subgroup analysis of the PERMIT study demonstrated the effectiveness and good tolerability of PER in people with IGE when administered under everyday clinical practice conditions. These findings are in line with clinical trial evidence, supporting PER's use as broad-spectrum antiseizure medication for the treatment of IGE.

Commentary: Consensus Guidelines on the Appropriate Use of Brand-Name and Generic Anti-Seizure Medication for the Management of Epilepsy in the Gulf Region

INTRODUCTION

The clinical, social, and economic burden of epilepsy is undeniable. Local guidance on epilepsy management is limited and needed to address the both use of anti-seizure medication (ASM) and switching practices which influence clinical outcomes.

AREAS COVERED

An expert panel composed of practicing neurologists and epileptologists from countries of the Gulf Cooperation Council (GCC) met in 2022 to discuss local challenges in the management of epilepsy and formulate recommendations for clinical practice. Published literature on the outcomes of ASM switching was reviewed along with clinical practice/gaps, international guidelines, and local treatment availabilities.

EXPERT OPINION

Improper ASM use and inappropriate brand-name-to-generic or generic-to-generic switching can contribute to worsening clinical outcomes in epilepsy. ASMs should be used for the management of epilepsy based on patient clinical profile, underlying epilepsy syndrome, and drug availability to ensure optimal and sustainable treatment. Both first-generation and newer ASMs can be considered; appropriate use is recommended from the beginning of treatment. It is critical to avoid inappropriate ASM switching to avoid breakthrough seizures. All generic ASMs should fulfill strict regulatory requirements. If needed, ASM changes should always be approved by the treating physician. ASM switching (brand-name-to-generic, generic-to-generic, generic-to-brand-name) should be avoided in epilepsy patients who have achieved control but can be considered for those uncontrolled on current medication.

A global survey on the attitudes of neurologists and psychiatrists about functional/psychogenic/dissociative/nonepileptic-seizures/attacks, in the search of its name

PURPOSE

We conducted an observational study to investigate the opinions of neurologists and psychiatrists all around the world who are taking care of patients with seizures [epilepsy and functional seizures (FS)].

METHODS

Practicing neurologists and psychiatrists from around the world were invited to participate in an online survey. On 29th September 2022, an e-mail including a questionnaire was sent to the members of the International Research in Epilepsy (IR-Epil) Consortium. The study was closed on 1st March 2023. The survey, conducted in English, included questions about physicians' opinions about FS and anonymously collected data.

RESULTS

In total, 1003 physicians from different regions of the world participated in the study. Both neurologists and psychiatrists identified "seizures" as their preferred term. Overall, the most preferred modifiers for "seizures" were "psychogenic" followed by "functional" by both groups. Most participants (57.9%) considered FS more difficult to treat compared to epilepsy. Both psychological and biological problems were considered as the underlying cause of FS by 61% of the respondents. Psychotherapy was considered the first treatment option for patients with FS (79.9%).

CONCLUSION

Our study represents the first large-scale attempt of investigating physicianś attitudes and opinions about a condition that is both frequent and clinically important. It shows that there is a broad spectrum of terms used by physicians to refer to FS. It also suggests that the biopsychosocial model has gained its status as a widely used framework to interpret and inform clinical practice on the management of patients.

Real-world experience of erenumab in patients with chronic or episodic migraine in the UAE

Background

Erenumab is a fully human monoclonal antibody and a highly potent, first-in-class calcitonin gene-related peptide receptor inhibitor approved for migraine prevention in adults. Randomised, placebo-controlled trials show that erenumab treatment results in clinically meaningful responses, including significant reductions in monthly migraine days. Real-world evidence of the effectiveness of erenumab in patients with migraine is accruing, but gaps remain, and findings may vary according to region. We evaluated the usage patterns and effectiveness of erenumab in real-world settings in patients with migraine in the United Arab Emirates (UAE).

Methods

This retrospective, observational real-world study enrolled patients ≥ 18 years with migraine who were prescribed erenumab in the UAE. Data were collected at baseline and Months 1, 3 and 6. The primary study objective was to characterise usage patterns of erenumab in patients with chronic migraine (CM) or episodic migraine (EM) in real-world settings in the UAE.

Results

Of the 166 patients, 124 (74.7%) were females. The mean (standard deviation) age at migraine onset was 29 (7.93) years. Seventy-one patients (42.8%) had CM and 95 (57.2%) had EM.

In the overall population, the mean monthly headache/migraine days (MHD) at baseline was 15.7 (8.45) and mean change from baseline was − 8.2 (8.83) at Month 1, − 11.0 (9.15) at Month 3 and − 11.3 (8.90) at Month 6. The mean change from baseline in monthly acute migraine-specific medication days (MSMD) was − 9.0 (8.07) at Month 1, − 9.7 (8.73) at Month 3 and − 10.7 (8.95) at Month 6. At all time points, most patients achieved at least 50% reduction in MHD (80%–91%) and MSMD (84%–94%).

Similar reductions in MHD and MSMD and clinical benefit in CM or EM were seen with erenumab monotherapy or erenumab add-on therapy, with or without dose escalation and for treatment naïve or ≥ 1 previous preventive treatment failures, with additional clinical benefit in the erenumab add-on therapy and dose escalation to 140 mg subgroups.

Conclusion

In this real-world study on erenumab use in the UAE, patients prescribed erenumab achieved clinically meaningful reductions in MHD and MSMD at all assessed time points. Erenumab was well tolerated with no new safety events.

ILAE definition of the Idiopathic Generalized Epilepsy Syndromes: Position statement by the ILAE Task Force on Nosology and Definitions

In 2017, the International League Against Epilepsy (ILAE) Classification of Epilepsies described the "genetic generalized epilepsies" (GGEs), which contained the "idiopathic generalized epilepsies" (IGEs). The goal of this paper is to delineate the four syndromes comprising the IGEs, namely childhood absence epilepsy, juvenile absence epilepsy, juvenile myoclonic epilepsy, and epilepsy with generalized tonic-clonic seizures alone. We provide updated diagnostic criteria for these IGE syndromes determined by the expert consensus opinion of the ILAE's Task Force on Nosology and Definitions (2017-2021) and international external experts outside our Task Force. We incorporate current knowledge from recent advances in genetic, imaging, and electroencephalographic studies, together with current terminology and classification of seizures and epilepsies. Patients that do not fulfill criteria for one of these syndromes, but that have one, or a combination, of the following generalized seizure types: absence, myoclonic, tonic-clonic and myoclonic-tonic-clonic seizures, with 2.5-5.5 Hz generalized spike-wave should be classified as having GGE. Recognizing these four IGE syndromes as a special grouping among the GGEs is helpful, as they carry prognostic and therapeutic implications.

Methodology for classification and definition of epilepsy syndromes with list of syndromes: Report of the ILAE Task Force on Nosology and Definitions

Epilepsy syndromes have been recognized for >50 years, as distinct electroclinical phenotypes with therapeutic and prognostic implications. Nonetheless, no formally accepted International League Against Epilepsy (ILAE) classification of epilepsy syndromes has existed. The ILAE Task Force on Nosology and Definitions was established to reach consensus regarding which entities fulfilled criteria for an epilepsy syndrome and to provide definitions for each syndrome. We defined an epilepsy syndrome as "a characteristic cluster of clinical and electroencephalographic features, often supported by specific etiological findings (structural, genetic, metabolic, immune, and infectious)." The diagnosis of a syndrome in an individual with epilepsy frequently carries prognostic and treatment implications. Syndromes often have age-dependent presentations and a range of specific comorbidities. This paper describes the guiding principles and process for syndrome identification in both children and adults, and the template of clinical data included for each syndrome. We divided syndromes into typical age at onset, and further characterized them based on seizure and epilepsy types and association with developmental and/or epileptic encephalopathy or progressive neurological deterioration. Definitions for each specific syndrome are contained within the corresponding position papers.

International League Against Epilepsy classification and definition of epilepsy syndromes with onset at a variable age: position statement by the ILAE Task Force on Nosology and Definitions

The goal of this paper is to provide updated diagnostic criteria for the epilepsy syndromes that have a variable age of onset, based on expert consensus of the International League Against Epilepsy Nosology and Definitions Taskforce (2017-2021). We use language consistent with current accepted epilepsy and seizure classifications and incorporate knowledge from advances in genetics, electroencephalography, and imaging. Our aim in delineating the epilepsy syndromes that present at a variable age is to aid diagnosis and to guide investigations for etiology and treatments for these patients.

Sudden unexpected death in epilepsy: A pilot study on neurologists' knowledge and experience in the Eastern Mediterranean region

Background- Sudden unexpected death in epilepsy (SUDEP) is an important concern in patients with epilepsy who are otherwise healthy. Current knowledge of SUDEP and attitudes of neurologists in the Eastern Mediterranean Region (EMR) towards discussing SUDEP with their patients remain unknown. Objective- We aimed at assessing knowledge, attitudes and factors affecting SUDEP discussion practices of neurologists practicing in the EMR. Methodology- An electronic and paper-based survey was sent to 350 neurologists practicing in the EMR. They were questioned about the frequency, timing, and factors affecting their willingness to initiate SUDEP discussion. We also included questions about perceived patient reactions towards SUDEP discussions and neurologists' preferred way to provide SUDEP information to their patients. Results- We received 132 responses from the 350 surveys sent out (response rate 37.7%). Our results showed that only 1.5% of the neurologists discussed SUDEP with "most" of their patients and their caregivers while 55.3% "rarely" or "never" discussed it. Factors such as additional epilepsy training and more years of clinical experience did not significantly affect the frequency of SUDEP discussion (p = 0.329, p = 0.728). A significant negative association between the number of patients seen per year and the frequency of SUDEP discussion was seen (P= 0.046). Based on their selection of known risk factors, 81% of neurologists were considered as having insufficient knowledge of SUDEP. The top three perceived reactions by the neurologists on SUDEP discussion were distress (74.2%), anxiety (70.5%) and depression (65.9%). Most neurologists initiated SUDEP discussion by themselves and preferred brochures/pamphlets, websites and training sessions to provide SUDEP information. Conclusion- Neurologists in the EMR rarely discuss SUDEP, and have limited knowledge about its risk factors. Upon discussing SUDEP, they overwhelmingly receive negative reactions but not always. Based on our findings, we believe an unintended knowledge gap exists on part of the neurologists. This, coupled with a lack of trained epilepsy nurses and patient education material in regional languages can also be attributed to poor SUDEP discussion practices in the EMR.

Position of Cladribine Tablets in the Management of Relapsing-Remitting Multiple Sclerosis: An Expert Narrative Review From the United Arab Emirates

The use of immune reconstitution therapies (IRT) in patients with relapsing-remitting multiple sclerosis (RRMS) is associated with a prolonged period of freedom from relapses in the absence of continuously applied therapy. Cladribine tablets is a disease-modifying treatment (DMT) indicated for highly active relapsing multiple sclerosis (MS) as defined by clinical or imaging features. Treatment with cladribine tablets is effective and well tolerated in patients with active MS disease and have a low burden of monitoring during and following treatment. In this article, an expert group of specialist neurologists involved in the care of patients with MS in the United Arab Emirates provides their consensus recommendations for the practical use of cladribine tablets according to the presenting phenotype of patients with RRMS. The IRT approach may be especially useful for patients with highly active MS insufficiently responsive to treatment with a first-line DMT, those who are likely to adhere poorly to a continuous therapeutic regimen, treatment-naïve patients with high disease activity at first presentation, or patients planning a family who are prepared to wait until at least 6 months after the end of treatment. Information available to date does not suggest an adverse interaction between cladribine tablets and COVID-19 infection. Data are unavailable at this time regarding the efficacy of COVID-19 vaccination in patients treated with cladribine tablets. Robust immunological responses to COVID-19 infection or to other vaccines have been observed in patients receiving this treatment, and treatment with cladribine tablets per se should not represent a barrier to this vaccination.

Complementary and alternative medicine in epilepsy: A global survey of physicians' opinions

PURPOSE

To investigate the opinions of physicians on the use of complementary and alternative medicine (CAM) in patients with epilepsy (PWE) worldwide.

METHODS

Online survey addressed to neurologists and psychiatrists from different countries.

RESULTS

Totally, 1112 physicians from 25 countries (different world region: Europe, North America, South America, Middle-East, Africa, Former Soviet Union Republics) participated; 804 (72.3%) believed that CAM might be helpful in PWE. The most commonly endorsed CAM included meditation (41%) and yoga (39%). Female sex, psychiatry specialization, and working in North and South America were associated with the belief that CAM is helpful in PWE. Two-hundred and forty five out of 1098 participants (22.3%) used/prescribed CAM to PWE; among them, 174 (71%) people perceived CAM to be less effective and 114 (46.5%) people found CAM to be safer than conventional antiseizure medications (ASMs). The most common reasons to prescribe CAM for PWE were: to satisfy the patient (49.9%), dissatisfaction with the efficacy (35.6%), and dissatisfaction with the adverse effects (31.2%) of conventional therapies.

CONCLUSION

Although the evidence supporting the use of CAM for the treatment of epilepsy is extremely sparse, most physicians worldwide believe that it could be integrated with the use of conventional ASMs, at least in some patients. High-quality controlled trials are warranted to provide robust evidence on the usefulness of CAM options in PWE.

Four-year survey of medically serious suicide attempters in Abu Dhabi

Background

It is well established that attempting suicide significantly increases a person's risk of completing suicide. The risk is considered to be particularly high in the first year after the attempt. Epidemiological information on suicide is scarce in the Middle East and the countries of the GCC region and there is a need to establish a reference point to measure future changes.

Aims

We examined the epidemiology of suicide attempters requiring inpatient care in Abu Dhabi to identify associated factors that could aid local suicide prevention strategies.

Methods

This 4-year (2011-2014) study of suicide attempters in the city of Abu Dhabi included all attempters assessed by the consultation-liaison team and admitted to the 3 main governmental general hospitals.

Results

We identified 364 suicide attempts with an annual incidence of 6 per 100 000 population. The mean age was 28.7 years. Females comprised 59.6% of the attempters and were more likely to be below age 30 years. Around 40% of the psychiatric diagnoses among attempters were related to stress and 17.9% to depression. Overdosing was the chosen method in 50.6% of the attempters, with 32.7% overdosing on paracetamol and females being more likely to use this method. Just over 13% of the attempters had made one previous attempt and 2.2% had made more than one.

Conclusion

Females younger than 30 years were at higher risk of attempting suicide, with overdosing on paracetamol as the preferred method. Stress-related diagnoses were predominant in the attempters.

Real-world retrospective study of effectiveness and safety of FINgOlimod in relapsing remitting multiple sclerosis in the Middle East and North Africa (FINOMENA)

OBJECTIVES

Evidence on the effectiveness and safety of fingolimod in real-world clinical practice in the Middle East and North African (MENA) region is limited. This study aimed to evaluate the effectiveness and safety of fingolimod in patients with relapsing-remitting multiple sclerosis (RRMS) in real-world setting in the MENA region.

PATIENTS AND METHODS

RRMS patients who had been treated with fingolimod for at least 12 months were retrospectively identified from the databases of 34 centers across the MENA region. Study outcomes included the annualized relapse rate (ARR), relapse-free rate (RFR), time to first and second relapses, mean change in Expanded Disability Status Scale (EDSS), proportion of patients with Magnetic Resonance Imaging (MRI) activity and no evidence of disease activity (NEDA)-3, retention of patients on treatment, as well as all safety measures.

RESULTS

A total of 806 patients were included: 66.34 % female; mean age 32.97 ± 9.62 years; mean disease duration 4.92 ± 4.66 years; mean fingolimod use 37.2 ± 16.7 months. Most patients had received previous disease-modifying therapy (79.65 %). Compared to the year preceding fingolimod initiation, RFR improved (33.00%-86.35%; p < 0.001), ARR decreased (0.84 ± 0.73 to 0.16 ± 0.45; p = 0.005), EDSS decreased (2.69 ± 1.74-2.01 ± 1.66; p < 0.001), and the proportion of patients with Gadolinium-enhancing T1 lesions decreased (57.84 % to 12.93 %; p < 0.001), after 12 months of fingolimod treatment. NEDA-3 was achieved in 41.3 % of patients. Median time to first and second relapses was not reached since 86.35 % and 98.39 % of patients had not experienced relapses for the first time and second time, respectively. Eight-hundred one (99.38 %) patients continued fingolimod treatment beyond 12 months. One-hundred thirty patients (16.13 %) experienced adverse events, mainly lymphopenia (5.46 %) and leukopenia (2.11 %), while 13 patients (1.61 %) experienced serious adverse events.

CONCLUSION

This study confirms the effectiveness and safety profile of fingolimod in real-world setting in the Middle East and North African (MENA) region.

Working restrictions and disability benefits eligibility in patients with functional (psychogenic) seizures: An international survey of physicians' opinions

OBJECTIVES

In this international study, we aimed to investigate the opinions of physicians dealing with patients with functional seizures (FS) worldwide on working restrictions and disability benefits eligibility.

METHODS

International online survey of neurologists/mental health professionals from Argentina, Venezuela, Colombia, Italy, France, Iran, Iraq, United Arab Emirates (UAE), Qatar, Saudi Arabia, Georgia, and Russia.

RESULTS

Six hundred and twenty-seven physicians from 12 countries participated in the study. Working as a neurologist was a predictor to think that patients with FS should not be counseled to avoid performing all jobs or professions as long as they have active disease (OR: 0.46; 95% CI: 0.30 to 0.68; p < 0.001). Having managed more than 200 patients was associated with the opinion that patients should not be counseled to avoid performing any type of work (OR: 2.17; 95% CI: 1.02 to 4.59; p = 0.043). Working as a psychiatrist/psychologist was associated with the idea that patients with FS should be qualified for disability benefits (OR: 1.97; 95% CI: 1.21-3.21; p = 0.006), and receive these benefits lifelong (OR: 0.43; 95% CI: 0.22-0.84; p = 0.014).

CONCLUSION

Neurologists and mental health professionals have different attitudes and opinions toward working restrictions and disability benefits for patients with FS. Further studies should investigate the reasons for these differences, and propose solutions to avoid discrimination and unequal access to employment and disability benefits.

Social aspects of life in patients with functional (psychogenic nonepileptic) seizures: An international study

PURPOSE

To explore various social aspects of life (i.e., employment, education, and driving) in a large sample of patients with functional seizures (FS) living in seven countries from four continents.

METHODS

In this retrospective study, we investigated adult patients with FS, who were admitted to the epilepsy monitoring units at centers in Iran, Qatar, USA, France, Georgia, Egypt, and United Arab Emirates (UAE). We studied the social aspects of life in the whole cohort. Then, we compared the social aspects of life between different world regions.

RESULTS

Four hundred and forty patients were included (241 from Iran, 56 from Qatar, 52 from France, 41 from the USA, 19 from UAE, 18 from Egypt, and 13 from Georgia). One hundred and twenty six people (30%) had college education, 142 (33%) were employed, and 101 (28%) drove a motor vehicle in their routine daily lives. People with FS and college education were more likely to report a history of sexual abuse compared with those with a lower education. Patients with no loss of responsiveness with their FS were more likely to be employed. Male patients and patients without aura were more likely to drive a motor vehicle in their routine daily lives. None of the social characteristics of the patients with FS showed significant differences among the two large culturally different groups (Muslim nations vs. Christian nations).

CONCLUSION

It appears that patients with FS across cultures have significant problems in their social aspects of life.

Disease-Modifying Drugs and Family Planning in People with Multiple Sclerosis: A Consensus Narrative Review from the Gulf Region

Most disease-modifying drugs (DMDs) are contraindicated in pregnancy. Management of MS is especially challenging for pregnant patients, as withdrawal of DMDs leave the patient at risk of increased disease activity. We, a group of experts in MS care from countries in the Arab Gulf, present our consensus recommendations on the management of MS in these patients. Where possible, a patient planning pregnancy can be switched to a DMD considered safe in this setting. Interferon β now can be used during pregnancy, where there is a clinical need to maintain treatment, in addition to glatiramer acetate. Natalizumab (usually to 30 weeks' gestation for patients with high disease activity at high risk of relapse and disability progression) may also be continued into pregnancy. Cladribine tablets and alemtuzumab have been hypothesised to act as immune reconstitution therapies (IRTs). These drugs provide a period of prolonged freedom from relapses for many patients, but the patient must be prepared to wait for up to 20 months from initiation of therapy before becoming pregnant. If a patient becomes pregnant while taking fingolimod, and requires continued DMD treatment, a switch to interferon β or natalizumab after a variable washout period may be prescribed, depending on the level of disease activity. Women who wish to breastfeed should be encouraged to do so, and interferon β may also be used during breastfeeding. There is a lack of data regarding the safety of using other DMDs during breastfeeding.

Clinical characteristics of functional (psychogenic nonepileptic) seizures: An international retrospective study

PURPOSE

We conducted a multicenter international cross-cultural comparative study to investigate clinical semiology and predisposing factors of functional seizures in a large cohort of patients living in different countries around the world. We hypothesized that semiology and predisposing factors of functional seizures differ between various world regions.

METHODS

We conducted this retrospective observational study in adults with functional seizures admitted to epilepsy centers in Iran, Qatar, USA, France, Georgia, Egypt, and United Arab Emirates (UAE). We assessed and compared the demographic and clinical seizure characteristics of these patients, according to the patients' reports and review of the ictal recordings during video-electroencephalogram (EEG) monitoring.

RESULTS

Five hundred nine patients were included (270 from Iran, 74 from Qatar, 63 from France, 43 from the USA, 22 from Egypt, 20 from UAE, and 17 from Georgia). Although all major manifestations of functional seizures (e.g., aura, loss of responsiveness, generalized motor seizures, ictal injury) were seen in all world regions, seizure semiology differed significantly across countries. Auras, ictal urinary incontinence, and ictal injury were more commonly reported by the American patients than patients from other world regions, whereas loss of responsiveness and generalized motor seizures were more frequently observed in the Iranian and American patients than the European and Arab patients.

CONCLUSION

Semiology of functional seizures seems to vary across various regions of the world; socioeconomic, cultural, ethnic, and religious differences may play an essential role in the modulation of functional seizures semiology across different nations and cultures.

High-efficacy therapies for relapsing-remitting multiple sclerosis: implications for adherence. An expert opinion from the United Arab Emirates

The number of disease-modifying treatments (DMDs) for relapsing-remitting multiple sclerosis has increased. DMDs differ not only in their efficacy and safety/tolerability, but also in the treatment burden of, associated with their initiation, route/frequency of administration, maintenance treatment and monitoring. High-efficacy DMDs bring the prospect of improved suppression of relapses and progression of disability, but may have serious safety issues, and burdensome long-term monitoring. Studies of patient preferences in this area have focused on side effects, efficacy and route of administration. Adherence to DMDs is often suboptimal in relapsing-remitting multiple sclerosis and there is a need to understand more about how the complex therapeutic and administration profiles of newer DMDs interact with these barriers to support optimal adherence to therapy.

Consensus recommendations for the diagnosis and treatment of multiple sclerosis: 2019 revisions to the MENACTRIMS guidelines

With evolving diagnostic criteria and the advent of new oral and parenteral therapies for MS, most current diagnostic and treatment algorithms need revision and updating. The diagnosis of MS relies on incorporating clinical and paraclinical findings to prove dissemination in space and in time, and exclude alternative diseases that can explain the findings at hand. The differential diagnostic workup should be guided by clinical and laboratory red flags to avoid unnecessary tests. Appropriate selection of multiple sclerosis (MS) therapies is critical to maximize patient benefit. The current guidelines review the scientific evidence supporting treatment of acute relapses, radiologically isolated syndrome, clinically isolated syndrome, relapsing remitting MS, and progressive MS. The purpose of these guidelines is to provide practical recommendations and algorithms for the diagnosis and treatment of MS based on current scientific evidence and clinical experience.

Multiple Sclerosis, Anxiety, and Depression in the United Arab Emirates: Does Social Stigma Prevent Treatment?

Background

Depression rates in the multiple sclerosis (MS) population in the Arab world have rarely been reported despite people with MS generally having higher rates of depression. We examined depression rates in 416 people with MS versus the general population of Abu Dhabi, United Arab Emirates, and their treatment.

Methods

A retrospective medical record review of 416 people with MS (age range, 16-80 years) followed up at four large government hospitals in Abu Dhabi was conducted to determine the percentage of people with MS diagnosed as having depression or anxiety.

Results

The depression rate in people with MS (10.8%) was close to that in the general population of Abu Dhabi. The adjusted odds ratios of depression by selected variables showed that there was a significant difference (P = .003) between females and males in reporting depression, with more females reporting depression than males. Greater MS duration was also associated with a higher likelihood of being depressed (P = .025). The anxiety rate in the cohort (4.8%) was lower than that in the general Abu Dhabi population (18.7%).

Conclusions

The depression rate in people with MS in Abu Dhabi was close to that of the general Abu Dhabi population, but the anxiety rate in people with MS was lower. Explanations for these low rates include possible underreporting by patients and physician factors such as time limitations in busy clinics. Cultural aspects such as strong family support systems and religious factors in this predominantly Muslim population are also possible factors that warrant further investigation.

Psychiatric Comorbidity in Neurological Disorders: Towards a Multidisciplinary Approach to Illness Management in the United Arab Emirates

Aim: To determine the prevalence of mood and anxiety disorders in undiagnosed patients attending neurological services, and detect rates of referral to and attendance of psychiatric services. Methods: Depressive symptoms and anxiety were assessed in 395 adult patients with primary diagnoses of neurological disorders. The Patient Health Questionnaire nine-item depression scale (PHQ-9), and Generalized Anxiety Disorder seven-item scale (GAD-7) were administered. Demographic details of the patients were recorded. Referral to and attendance of psychiatric services were recorded for patients scoring within the clinical range of depression and anxiety disorders (scores > 10). Results: There was a 39% prevalence rate of depressive symptoms, 34% rate of anxiety, and 35.4% concurrent rate of both disorders in this cohort. The referral rate to psychiatric services was 33.6%, and attendance rate was 47.8%. There was significant association between severity of psychiatric symptoms and referral to psychiatric services, as well as significant association between comorbid psychiatric symptoms and attendance to psychiatric services. Conclusion: Our results indicate similar prevalence rates of comorbid psychiatric symptoms to studies carried out in the Middle East and North Africa (MENA) region and relatively high attendance and referral rates to psychiatric services. Implications: The results shed light on the clinical profile of patients in this region and support the need for integrated collaborative medical services. Moreover, findings have important implications for health care policies pertaining to resource distribution and funding.

Suicide attempters in Abu Dhabi: Is criminal prosecution associated with patients' guardedness?

The objective of this study was to examine the relationship between legal status and guardedness in patients who attempted suicide in Abu Dhabi, United Arab Emirates. The consultation-liaison team assessed 355 patients admitted for suicidal/self-injurious behavior, recording their guardedness before knowing whether they were legally charged. Patients who were legally charged for the suicidal act (n = 139) were 1.6 times (p = .03) more guarded in volunteering information than patients who were not legally charged. Legally charging suicide attempters might have a negative impact on risk assessment and psychiatric care.

Prevalence and characteristics of transverse myelitis and neuromyelitis optica spectrum disorders in the United Arab Emirates: A multicenter, retrospective study

Objective

To determine the epidemiology and characteristics of transverse myelitis (TM) and neuromyelitis optica spectrum disorders (NMOSD) in Abu Dhabi, United Arab Emirates.

Methods

Retrospective chart review at four large government-run hospitals in Abu Dhabi between 2010 and 2016. Data collected included year of onset, presentation, laboratory results including aquaporin-4 immunoglobulin G (IgG)/myelin oligodendrocyte glycoprotein IgG antibodies and the occurrence of any relapses.

Results

A total of 46 individuals were identified. Of these, 23 (50%) were Emirati citizens. Within the overall group including pediatrics, the crude prevalence rate for monophasic TM was 1.0 per 100 000, and for NMOSD was 0.34 per 100 000. Incidence rates within the overall group for TM and NMOSD were 0.18 per 100 000 and 0.05 per 100 000, respectively. For Emirati citizens aged ≥20 years, the prevalence rate for monophasic TM was 2.46 per 100 000 and 1.76 per 100 000 for NMOSD, and the incidence was 0.57 per 100 000 and 0.17 per 100 000, respectively. The incidence of monophasic TM and NMOSD within the Emirati pediatric population (aged ≤19 years) was 0.18 per 100 000 and 0.06 per 100 000, respectively. The mean age of onset for monophasic TM was 36 years, and for NMOSD was 43 years. Nine patients had a positive aquaporin-4 IgG or anti-myelin oligodendrocyte glycoprotein IgG antibody result. Of the 30 participants with available laboratory cerebrospinal fluid analysis, 36.6% had elevated white blood counts (>5.0 × 10⁶/L), and 43% had elevated protein levels. A total of 19 participants had documentation of oligoclonal bands or IgG index, and just four (21%) had either oligoclonal bands or elevated IgG index.

Conclusion

The present study describes the epidemiology and characteristics of TM and NMOSD among populations in Abu Dhabi. The adult prevalence rate for Emirati citizens was 2.46 per 100 000 for monophasic TM, and 1.76 per 100 000 for NMOSD. The overall incidence was 0.18 per 100 000 and 0.05 per 100 000, respectively.

Pediatric Multiple Sclerosis in the United Arab Emirates: Characteristics From a Multicenter Study and Global Comparison

We delineate the clinical characteristics, incidence, and prevalence of pediatric-onset multiple sclerosis in Abu Dhabi, United Arab Emirates, from 2010 to 2014. Eighty-two patients (65% female) were identified. Fifty-three (64.6%) were Emiratis (45 from Abu Dhabi and 8 from 5 other emirates) and 29 were expatriates. Mean age of onset was 15.9 years overall, 15.3 years in males and 16.3 years in females. Patients with onset before age 12 years presented with visual symptoms while those with onset after age 12 years presented with a mixture of visual, motor and sensory symptoms. Interferon beta-1a was the most frequently used disease-modifying therapy (48%). In Abu Dhabi Emirati nationals, the age- and sex-adjusted prevalences were 26/100 000 for males and 36/100 000 for females. The total incidence in Emirati nationals from 2010 to 2014 was 2.3/100 000 for ages 10 to 14 years and 7.2/100 000 for ages 15 to 19 years. By comparison with international cohorts, the incidence of pediatric-onset multiple sclerosis in Abu Dhabi is higher whereas gender distribution is similar.

Depression and anxiety as determinants of health-related quality of life in patients with multiple sclerosis - United Arab Emirates

To study the impact of depression and anxiety on health-related quality of life (HRQOL) in patients with multiple sclerosis (pwMS) in the UAE. All consecutive patients attending the MS clinic over a fourmonth period, October 2014 through February 2015, at Sheikh Khalifa Medical city (SKMC) were asked to complete The World Health Organization quality of life abbreviated scale (WHOQOL-BREF), the Patient Health Questionnaire nine-item (PHQ-9) depression scale, and Generalized Anxiety Disorder seven-item (GAD-7) scale. These last two scales were used to screen for depression and anxiety disorders respectively. The study looked at significant variables associated with HRQOL, using multivariate analysis. Eighty patients were enrolled in the study. Both anxiety and depression had a strong positive correlation with HRQOL in univariate analysis. However, depression was the strongest predictor of HRQOL in the patients using linear multi-regression analysis. Screening and timely treatment of both anxiety and depression in MS patients should be a recommended policy when managing pwMS to improve their optimal care and ensure better quality of life.

Potential factors impacting health-related quality of life among patients with epilepsy: Results from the United Arab Emirates

PURPOSE

to investigate potential factors impacting HRQOL among PWE at a medical facility in the UAE.

METHODS

Depression, anxiety, and health-related quality of life were assessed in 160 adult patients with epilepsy from September 2014 to January 2015 at Sheikh Khalifa Medical City (SKMC). The World Health Organization Quality of Life abbreviated scale (WHOQOL-BREF), the Patient Health Questionnaire nine-item (PHQ-9) depression scale, and Generalized Anxiety Disorder seven-item (GAD-7) scale were administered. Demographic details including psychosocial factors were also obtained. Clinical details including seizure freedom, epilepsy type, epilepsy duration, and magnetic resonance imaging (MRI) results were recorded. Multivariate analysis was used to look at significant variables associated with HRQOL.

RESULTS

Depression, anxiety, seizure freedom, and the use of anti-depressants had significant positive correlation with HRQOL in univariate analysis. However, depression, followed by seizure freedom, had the strongest association with HRQOL in a multivariate regression analysis.

CONCLUSION

Depression and seizure freedom, followed by anxiety and anti-depressants use, were significantly correlated with HRQOL. These results underscore the importance of screening for psychiatric comorbidities in patients with epilepsy.

IMPLICATIONS

Screening for comorbid psychiatric disorders should be an essential component of the standard of care, and incorporated in the treatment plan for all patients with epilepsy. Factors contributing to psychiatric symptoms among PWE, such as maladaptive illness perceptions, non-adherence to anti-epileptic drugs (AED), and social stigma should be carefully addressed to achieve an optimal health-care plan.

How global MS prevalence is changing: A retrospective chart review in the United Arab Emirates

BACKGROUND

Multiple Sclerosis (MS) is an autoimmune disorder leading to central nervous system inflammation. Traditionally, reported MS prevalence rates in the Middle East are low. Few studies include age/sex standardization giving an unreliable estimate of regional prevalence.

OBJECTIVE

to determine the prevalence, incidence and characteristics of MS in Abu Dhabi, United Arab Emirates.

METHODS

A retrospective chart review was conducted at the four largest hospitals in Abu Dhabi Emirate between 2010 and 2014. Data collected included MS type, age and symptoms at onset, expanded disability status scale, treatment, laboratory findings and family history.

RESULTS

510 patients were identified consisting of 318 (62.2%) Emiratis and 192 (37.6%) expatriates. Total crude prevalence rate was 18/100,000 (95% CI: 10-30/100,000). Crude prevalence rate in Emiratis was 57.09 (95% CI:50 to 63/100,000) but increased to 64.44 (95% CI: 57 to 72/100,000) when age standardized. Age-standardized incidence rate in Emiratis was 6.0 MS cases per 100,000 person-years (95% CI: 5.5 to 6.5 cases per 100,000 person-years).

CONCLUSION

At 64.44/100,000, the Abu Dhabi Emirati population has one of the highest, most reliable prevalence rate on the Arab peninsula. Age/sex standardized prevalence rates, uncommonly reported in the Middle East, should be standard for all prevalence studies.

Fatal coma in a young adult due to late-onset urea cycle deficiency presenting with a prolonged seizure: a case report

Introduction

Unexplained hyperammonemic coma in adults can be a medical dilemma in the absence of triggering factors and known comorbidities. Ornithine transcarbamylase deficiency presents most commonly with hyperammonemic coma. Although a rare disorder, ornithine transcarbamylase deficiency is the most common of the urea cycle disorders, which can occur both in children, and less commonly, in adults. The urea cycle disorder is usually acquired as an X-linked trait, and very rarely, similar to our reported case, may be acquired as a “new” mutation. Mutations that lead to later-onset presentations may lead to life-threatening disease and may be unrecognized, particularly when the first clinical symptoms occur in adulthood.

Case presentation

We report the case of a previously healthy 17-year-old white man who developed a prolonged seizure and a rapid decline in mental status leading to coma over a 3-day period. Analysis of the OTC gene showed a 119G variant, which was identified in exon 2 of the OTC gene by sequencing.

Conclusions

A diagnosis of ornithine transcarbamylase deficiency should be considered in adult patients who present with unexplained hyperammonemic coma and for all adult patients presenting with cryptogenic new-onset seizure and laboratory finding of elevated blood ammonia levels. This reported case highlights the importance of early recognition of this potentially reversible cause of life-threatening encephalopathy, as timely recognition and appropriate treatment can be lifesaving.

Prevalence of depression and anxiety among patients with epilepsy attending the epilepsy clinic at Sheikh Khalifa Medical City, UAE: A cross-sectional study

Depression and anxiety are highly prevalent in patients with epilepsy (PWE), with prevalence rates ranging from 20% to 55%. Unfortunately, the rates, patterns, and risk factors have not been well studied in the Middle East and, to our knowledge, have not been studied at all in the UAE. We screened 186 patients attending an epilepsy clinic using standardized screening tools to determine the rates of both depression and anxiety and compared these rates with that of age- and sex-matched controls. Almost one-third of our patients scored in the depression and anxiety ranges, which was significantly higher compared with the age- and sex-matched controls. Using a multiregression model, none of the studied variables were associated with an increased risk of having either disorder. Depression or anxiety symptoms independently and significantly increased the risk of association with the other disorder. Almost two-thirds of patients with depression and anxiety were not prescribed antidepressant or antianxiety medications.

Does pyridoxine control behavioral symptoms in adult patients treated with levetiracetam? Case series from UAE

Behavioral symptoms are known side effects of levetiracetam. Previous case series in children and adolescents have demonstrated the potential effect of pyridoxine in ameliorating these symptoms. We retrospectively reviewed the charts of 51 patients treated with pyridoxine to control agitation and irritability following the introduction of levetiracetam. These symptoms were relieved in 34 patients (66.6%). Seventeen patients did not appear to benefit from this supplementation. This preliminary study suggests that pyridoxine might be an effective option across all ages for patients suffering from levetiracetam-induced behavioral side effects.

VNS terminating refractory nonconvulsive SE secondary to anti-NMDA encephalitis: A case report

Anti-NMDA receptor encephalitis (ANRE) has been previously reported as a rare cause of nonconvulsive status epilepticus (NCSE). Vagus nerve stimulation (VNS) is generally considered as a palliative treatment for patients with drug-resistant partial-onset epilepsy. Here, we report a case of refractory NCSE that was terminated after vagus nerve stimulator implantation. To our knowledge, similar cases have not been reported previously.

Language lateralization in a patient with temporal lobe epilepsy and callosal agenesis

The corpus callosum has been proposed as a mechanism of interhemispheric inhibition that allows language dominance to develop [1]. Callosal agenesis or dysgenesis provides a test of this hypothesis, as patients lacking a normal corpus callosum should also lack normal language lateralization [2]. We report pre- and postoperative functional magnetic resonance imaging (fMRI) and neuropsychological testing in a patient with partial callosal agenesis who underwent a right temporal lobectomy for medically refractory seizures.

Consensus recommendations for the diagnosis and treatment of multiple sclerosis: the Middle East North Africa Committee for Treatment and Research In Multiple Sclerosis (MENACTRIMS)

With evolving diagnostic criteria and the advent of new oral and parenteral therapies for MS, most current diagnostic and treatment algorithms need re-evaluation and updating. The diagnosis of MS relies on incorporating clinical and paraclinical findings to prove dissemination in space and in time, and exclude alternative diseases that can explain the findings at hand. The differential diagnostic workup should be guided by clinical and laboratory red flags to avoid unnecessary tests. Appropriate multiple sclerosis (MS) therapy selection is critical to maximize patient benefit. The current guidelines review the scientific evidence supporting treatment of acute relapses, radiologically isolated syndrome, clinically isolated syndrome, relapsing remitting MS, secondary progressive MS, and primary progressive MS. The purpose of these guidelines is to provide practical recommendations and algorithms for the diagnosis and treatment of MS based on current scientific evidence and clinical experience.

Midwakh-induced seizures: case series from UAE

Drug-induced seizures are rare causes of hospital admissions (Coleman, 2004). Various classes of drugs are reported to induce seizures either directly, due to their epileptogenic potential or due to drug withdrawal effect, or indirectly, due to systemic and CNS-related side effects (Thundiyil et al., 2011). Midwakh is commonly used among young Emiratis. However, its CNS-related adverse effects are not well studied. We report seven consecutive patients with a history of seizures provoked by smoking midwakh and a negative workup for epilepsy. Six of these patients had no further seizures after they had agreed to discontinue smoking midwakh.

Consensus guidelines for the diagnosis and treatment of multiple sclerosis

The diagnosis of multiple sclerosis (MS) is dependent on the presence of clinical and paraclinical evidence demonstrating dissemination of central nervous system lesions in both space and time, as well as the exclusion of other disorders. Diagnostic criteria were originally promulgated in 1965 by the Schumacher committee and modified subsequently by the Poser committee to include paraclinical evidence. The most recent criteria are the 2010 modifications of the 2001 McDonald criteria, which are focused on making an earlier diagnosis of MS. This article provides guidelines, derived from clinical experience as well as evidence-based medicine, for the diagnosis and management of MS with special emphasis on practices in the Middle East.

Guidelines for the Pharmacological Treatment of Peripheral Neuropathic Pain: Expert Panel Recommendations for the Middle East Region

Neuropathic pain (NeP) has been the focus of extensive basic and clinical research over the past 20 years. This has led to an increased understanding of underlying pathophysiological mechanisms and the development of new therapeutic agents, as well as a clearer definition of the role of established medications. To date there are no published treatment guidelines for NeP in the Middle East. A multidisciplinary panel of Middle East and international experts met to review critically and reach a consensus on how best to apply evidence-based guidelines for the treatment of NeP (mainly peripheral NeP) in the Middle East. The expert panel recommended pregabalin, gabapentin and secondary amine tricyclic antidepressants (nortriptyline and desipramine) as first-line treatments for peripheral NeP. Serotonin-norepinephrine reuptake inhibitor antidepressants, tramadol and controlled-release opioid analgesics were recommended as second-line treatments. There is a need to increase diagnostic awareness of NeP, use validated screening questionnaires and undertake more treatment research in the Middle East region.
