Objective: To evaluate the long-term humoral immune response to Nipah virus (NiV) in a cohort of 25 survivors after 25 years of post-infection.

Methods: A total of 25 survivors of NiV infection from the 1998 outbreak were recruited for sample collection. The serum IgG antibody response to NiV antigens, specifically nucleocapsid (N), fusion glycoprotein (F) and attachment glycoprotein (G) was evaluated using ELISA.

Introduction: Psychiatric comorbidities such as depression and anxiety disorders are highly prevalent among people with epilepsy (PWE). These two co-occurring chronic illnesses could lead to double stigma and negatively impact every aspect of psychiatric and epilepsy care for PWE, especially in help-seeking behavior. We aimed to identify the socio-demographic and clinical factors contributing to reluctance to be referred to a psychiatrist among PWE.

Dengue virus is a flavivirus transmitted by the mosquitoes, Aedes aegypti and Aedes albopictus. Dengue infection by all four serotypes (DEN 1 to 4) is endemic globally in regions with tropical and subtropical climates, with an estimated 100-400 million infections annually. Among those hospitalized, the mortality is about 1%.

Objective: One of the objectives of the Intersectoral Global Action Plan on epilepsy and other neurological disorders for 2022 to 2031 is to ensure at least 80% of people with epilepsy (PWE) will have access to appropriate, affordable, and safe antiseizure medications (ASMs) by 2031. However, ASM affordability is a significant issue in low- and middle-income countries, preventing PWE from accessing optimal treatment. This study aimed to determine the affordability of the newer (second and third generation) ASMs in resource-limited countries in Asia.

Article Synopsis
  • Epilepsy is influenced by both genetic and environmental factors, with recent studies focusing on genetic risk variants and how they affect the balance between excitation and inhibition in the brain.
  • Researchers identified two specific genetic variants (GABRA1 and ERBB4) in a Malaysian Chinese family affected by genetic generalized epilepsy, which were linked to disturbances in this balance.
  • While all affected family members had both variants, those with only one variant showed no symptoms, indicating that the combination of both variants may lead to a greater risk of seizures and reinforcing the need for more research to confirm these findings.

Radiology-pathology correlation is essential for multidisciplinary collaboration in diagnosis and understanding the mechanism of CNS damage in infectious processes. The microscopic acute inflammatory processes are well established and are supplemented by a variety of less-invasive microbial and immunohistochemical investigations. Understanding the pathogenesis of pathogen spread and neuroinvasion, vascular and immune-mediated brain, and spinal cord damage are essential for interpreting radiological images.

Nipah virus (NiV) is a highly lethal zoonotic paramyxovirus that emerged in Malaysia in 1998. It is a human pathogen capable of causing severe respiratory infection and encephalitis. The natural reservoir of NiV, Pteropus fruit bats, remains a continuous virus source for future outbreaks, although infection in the bats is largely asymptomatic.

Background: This study aimed to determine the relationship among the clinical, logistic, and psychological impacts of COVID-19 on people with epilepsy (PWE), and the impact of COVID-19 on the quality of life.

Method: This is a cross-sectional anonymized web-based study on PWE, using an online questionnaire to assess the clinical, logistic, and psychological impacts of COVID-19, including Hospital Anxiety Depression Scale (HADS) and Quality of Life in Epilepsy Inventory (QOLIE-31).

Result: 461 patients were recruited, with a mean age of 39.
