Objective: Pharmacotherapy including mood stabilizers and antipsychotics are frequently used in bipolar disorder (BD); however, the lack of consensus regarding the definition of polypharmacy hinders conducting comparative studies across different settings and countries. Research on Asian Prescription Pattern (REAP) is the largest and the longest lasting international collaborative research in psychiatry in Asia. The objective of REAP BD was to investigate the prescription patterns of psychotropic medications across Asian countries. The rates of polypharmacy and psychotropic drug load were also analyzed. Methods: The data collection was web-based. Prescription patterns were categorized as (1) mood stabilizer monotherapy: one mood stabilizer; (2) antipsychotic monotherapy: one antipsychotic; (3) simple polypharmacy: one mood stabilizer and one antipsychotic; and (4) complex polypharmacy: ≥ 2 mood stabilizers or/and antipsychotics. The psychotropic drug load in each patient was calculated using the defined daily dose method. Results: Among 2003 patients with BD (52.1% female, 42.4 years) from 12 countries, 1,619 (80.8%) patients received mood stabilizers, 1,644 (82.14%) received antipsychotics, and 424 (21.2%) received antidepressants, with 14.7% mood stabilizer monotherapy, 13.4% antipsychotic monotherapy, 48.9% simple polypharmacy, 20.3% complex polypharmacy, and 2.6% other therapy. The average psychotropic drug load was 2.05 ± 1.40. Results varied widely between countries. Conclusion Over 70% of psychotropic regimens involved polypharmacy, which accords with the high prevalence of polypharmacy in BD under a permissive criterion (2 or more core psychotropic drugs) worldwide. Notably, ≥ 80% of our sample received antipsychotics, which may indicate an increasing trend in antipsychotic use for BD treatment.

Background & Objectives: The literature on cerebral venous thrombosis (CVT) in South East Asia is limited. The objectives were to evaluate the clinical profile, predisposing factors and clinical outcome of the CVT patients in Malaysia. Methods: We conducted a retrospective descriptive study of the CVT patients admitted to the neurology ward. The clinical presentation, predisposing factors, radiological findings, treatment and prognostic characteristics were evaluated from the charts. Clinical outcome on discharge and six months was measured by Modified Rankin Scale (mRS) scores. Poor outcome and good outcome was defined as Modified Rankin Scale (mRS) scores of 3-6 and 0-2 respectively. Results: Forty nine CVT patients who presented between 2007 and 2017 were recruited. The mean age was 43.51±16.52. The patients consisted of 39 Malaysians (13 Indians, 12 Malays, 12 Chinese, one Iban, one Eurasian descent), and ten non-Malaysians. Thirty (61.2%) patients were women. The most common presenting complaint was headache (75.5%). Six percent had multiple risk factors, whereas 51% had idiopathic CVT. The most common predisposing factors were oral contraceptive pill use (18.4%), followed by infection (12.2%), especially central nervous system (CNS) infection (6.1%); 11.8% had prothrombotic disorder. The most common location for CVT was superior sagittal sinus (83.7%). On neuroimaging, 77.6% had parenchymal lesions, 53.1% had venous infarcts and 38.8% had intracerebral haemorrhage, one patient had CVT complicated by rare venous collateral channels. Poor outcome on discharge and at six months was 38.8% and 33.3% respectively. On univariate analysis, female gender (p=0.002), seizures (p=0.037) and cerebral oedema (p=0.018) were associated with poor functional outcome. On binary logistic regression, female gender (OR=14.50, 95% CI 2.10-99.94,p=0.003) and seizures (OR=6.54, 95% CI 1.33-32.07, p=0.017) were associated with poor outcome. Conclusion: The CVT patients in this study had a higher proportion of CNS infections. Poor outcome was independently associated with female gender and seizures.

Background: The literature on complementary and alternative (CAM) therapies in South East Asia is limited. The objective of the study was to evaluate the frequencies of CAM therapies in the Malaysian patients with migraine and tension-type headache (TTH). We also assessed the reasons for CAM use. Methods: This was a cross-sectional study. The study was conducted in a tertiary hospital in Malaysia. Consecutive patients presenting with migraine and TTH to the neurology clinic were recruited. Demographic characteristics were documented. Data on CAM use, including frequency and the reasons was collected. Results: Six hundred and eighty five patients (365 TTH and 320 migraine) were recruited. They consisted of 305 (44.5%) Malay, 174 (25.4%) Chinese, 169 (24.7%) Indian and 37 (5.4%) patients from other ethnic groups. A total of 478 (69.8%) patients, comprising 266 (55.6%) patients with TTH and 212 (44.4%) patients with migraine used CAM therapies. The most commonly used CAM therapies were medicated oil (355 patients, 51.8%) and massage (246 patients, 35.9%). The most common reasons for CAM use were reduction of pain (47.7 %), stress reduction (34.9%), and “cooling” effect (27.4%). Thirteen (4.1%) patients with migraine practiced reflexology, whereas 5 (1.4%) patients with TTH practiced reflexology (p=0.032). Twenty three (7.2%) patients with migraine took vitamin supplements compared to 13 (3.6%) patients with TTH (p=0.039). On univariate analysis, CAM use was significantly associated with ethnic groups (p=0.014), gender (p<0.0001), age (p=0.004), salary (p=0.014), educational level (p=0.003), and headache subtypes (p= 0.067). On logistic regression, married women were more likely to use CAM (OR=1.864, 95% CI 1.216-2.858, p=0.004). Conclusion: A large number of Malaysian headache patients used CAM. The most common reasons were reduction of pain, stress and “heatiness”. Medicated oil was most commonly used, followed by massage. Married women were more likely to use CAM, and this was the only determinant in this study.

Neuroschistosomiasis is an infection of the central nervous system caused by Schistosoma species and constitute a severe manifestation of the disease. Schistosoma japonicum is well-known cause of cerebral schistosomiasis and Schistosoma mansoni for spinal schistosomiasis. Although neuroschistosomiasis is not rare, reports on cerebral vasculitis associated with Schistosoma mansoni infection is scarce. With regards to schistosomiasis in Asia, most of the published literature has been on Schistosoma japonicum and the prevalence of Schistosoma mansoni in Asia is not well established. We report here a 54-yearold Rakhine woman with history of diabetes mellitus for more than ten years presenting with three recurrent stroke occurring over 2 months, twelve months after returning to Yangon from Rakhine, an endemic area for Schistosoma mansoni infection. Cerebral MRA revealed beaded appearance along left ACA and segmental narrowing beyond terminal ICA both sides, and contrast enhancement was noted at left frontal lobe with restricted diffusion on MRI brain. Serum serology testing for Schistosoma mansoni infection was positive. With oral praziquantel and high dose corticosteroid, aphasia and swallowing improved. This is the first report of delayed onset cerebral vasculitis associated with chronic Schistosoma mansoni infection in Asia.

The last review on epilepsy in Southeast Asian (SEA) countries was reported in 1997. This review aimed to update the understanding of epilepsy management in this region over the past 23 years. There has been significant increase in the epidemiological studies which reported a prevalence of 4.3-7.7 per 1,000 populations in this region. Reversible aetiologies of epilepsy such as head injury, birth trauma, cerebrovascular disease, and intracranial infections (neurocysticercosis or meningoencephalitis) are still prevalent, with a surge in autoimmune encephalitis. There was a surge in genetic studies which suggest ethnic variation. Treatment gap is still high especially in the rural and less developed areas, and the availability and affordability of newer anti-epileptic drugs (AEDs) is still a major challenge in SEA. Alternative medicine is a common practice but varies among different ethnic groups. AEDs hypersensitivity especially on the association between HLA-B*1502 and carbamazepine-related severe cutaneous reaction had been extensively studied and proven in nearly all SEA countries. However, HLA-B*1502 screening is not widely available in SEA and the cost-effectiveness of the screening is questionable. Stigma and its psychosocial consequences are still a major concern despite enormous efforts to study the public attitudes towards epilepsy and change of epilepsy naming in a few countries. The number and complexity of epilepsy surgery are progressing, but it is still under-utilized in many SEA countries, related to cost, cultural perception and lack of facilities. More resources should also be channelled in training adequate number of epileptologists who can spearhead epilepsy care around the region, as well as public education and research in epilepsy. In conclusion, there is an increase in epilepsy research in this region, gradual increase in trained neurologists and facilities, and efforts to reduce the knowledge and treatment gap, but the epilepsy management gap is still a battle to fight.

Objective: Epilepsy is understudied in Southeast Asian (SEA) countries. This systematic review aimed to determine the number of epilepsy publications performed in SEA and identify factors associated with research output in this region. Methods: Existing academic journal article searches were performed using PubMed, Scopus, Medline and Web of Science till 1st March 2018. Openness is determined by the use of English in medical school and overseas epilepsy fellowship. Results: A total of 702 epilepsy articles have been published in the last 50 years in the SEA region, with an exponential increase of publications after the year 1997, with the cumulative number doubled every 5 years. Only half (54%) were published in the journals with impact factor (IF) ≥1. Majority of the publications (48.2%) employed cross sectional design, followed by animal or laboratory studies (21.1%), with few randomized controlled trials and systematic review/meta-analysis studies (1.7% and 2.3%, respectively). Half (52.9%) of the publications were clinical studies. The number of papers with IF≥1 correlated positively with openness to international standard (R=0.720, p<0.05), and knowledge-based economy (p=0.01). Conclusion: Epilepsy research output in SEA is low in quantity and quality. The output is mainly related to the type of economy (knowledge-based or non-knowledge-based) and openness to international ideas and standard.

Stigma in epilepsy arises from the misconceptions and prejudices rooted in the patient’s culture and traditions. Upbringing also has an important impact on the quality of life of epilepsy patients. In Chinese tradition, the main purpose of life is to be a “gentleman” 君子, to fully express the true human nature. The essence of being a gentleman is “benevolence” and “virtue”. According to Zhuangzi’s concept of “virtue overcoming deformity” 德充符, virtue can prevail over physical deficiencies. Consistent with such a principle, a person with epilepsy should receive high honour if he can demonstrate the character of a “gentleman”. In - traditional Chinese culture, the sense of shame is the foundation of morality; “feeling shame” 知耻 and “being shameless” 无耻 are important moral concepts. A gentleman has a sense of shame, whereas a “petty person” 小人 is shameless. However, the ability to resist feeling inappropriate shame - “not feeling ashamed” 不耻 is also a trait of the gentleman. Thus, based on traditional Chinese philosophy, one should resist feeling ashamed for having epilepsy. Chinese culture emphasizes the importance of exerting vitality in the presence of adversity; people with epilepsy who do not feel ashamed of their deficiency is manifesting such a vitality. Traditional Chinese culture takes a positive attitude towards hardship and adversity, that it is essential for developing character and skills. Overcoming adversity requires responsibilities, the pre-requisite is personal freedom. Thus, allowing freedom and nurturing independence is consistent with traditional Chinese attitude to upbringing.

Moyamoya disease (MMD) was first described in 1957 as “bilateral hypoplasia of internal carotid arteries (ICAs)”.1 Aside from involving the intracranial arteries, MMD can also affect extracranial ICAs and external carotid arteries (ECAs).2-4 High resolution magnetic resonance (MR) vessel wall imaging (VWI) is increasingly being used to help with the diagnosis and characterization of the condition focusing mainly on intracranial vessels and extracranial ICAs.5-9 We present a case of a young woman with MMD, demonstrating vessel wall enhancement of nonstenotic maxillary branches of bilateral ECAs.

Non-bacterial thrombotic endocarditis (NBTE) denotes the presence of sterile non-infective vegetation on structurally normal, or subtly degenerate cardiac valves and is often associated with advanced malignancies. In gynaecological cancer in particular, NBTE has been most commonly associated with ovarian cancer.1,2 Here we report a rare but interesting case of NBTE in a patient with locally advanced cervical adenocarcinoma.

Background & Objectives: Arachnoiditis which involves the optic chiasm and optic nervecan rarely occurs in the patients with tuberculous meningitis (TBM). The primary objective of this study was to determine the incidence, assess the clinical and neuroimaging findings, and associations, understand its pathogenesis of these patients, and determine its prognosis. Methods: The patients admitted with TBM in the neurology wards of two tertiary care hospitals from 2009 to 2017 in Kuala Lumpur, Malaysia were screened. The patients with OCA and optochiasmatic tuberculoma were included in this study. We assessed the clinical, cerebrospinal fluid (CSF), imaging findings of the study subjects and compared with other patients without OCA or optochiasmatic tuberculoma. Results: Eighty-eight patients with TBM were seen during the study period. Seven (8.0%) had OCA and one (1.1%) had optochiasmatic tuberculoma. Five out of seven (71.4%) patients with OCA were newly diagnosed cases of TBM. The other two (28.6%) had involvement while on treatment with antituberculous treatment (paradoxical manifestation). The mean age of the patients with OCA was 27.3 ± 11.7. All the OCA patients had leptomeningeal enhancement at other sites. All had hydrocephalus and cerebral infarcts on brain neuroimaging. Three (42.9%) patients had cerebral tuberculoma at sites other than suprasellar and optic chiasm areas. On univariate analysis, the presence of OCA and optochiasmatic tuberculoma was associated with raised CSF opening pressure (p=0.014), younger age (p=0.024), cerebral infarcts (p=0.018) and hydrocephalus (p= 0.046). There was no statistically significant association on logistic regression. Only one (14.3%) patient had visual impairment. Conclusion: OCA and optochiasmatic tuberculoma were seen in 9% of a cohort of Malaysian TBM patients. They were more likely to be younger, have raised CSF opening pressure, cerebral infarcts and hydrocephalus, suggesting the association with a more severe exudative disease.
