Hope In The Face Of Subacute Sclerosing Panencephalitis: A Case Report Of Complete Remission With Isoprinosine, Nimra Shafique, Syed Muhammad Essa, Amanullah Kakar

Pakistan Journal of Neurological Sciences (PJNS)

Subacute Sclerosing Panencephalitis (SSPE) is a rare and relentless neurodegenerative disorder linked to persistent measles virus infection. We present a case of a 16-year-old female with gradually worsening rigidity, cognitive decline, and myoclonic seizures, minimally responsive to valproic acid. A history of measles infection at the age of two years emerged. Positive cerebrospinal fluid (CSF) IgG and IgM anti-measles antibodies, along with an elevated CSF/serum antibody index, confirmed SSPE. Treatment with Inosine pranobex and clonazepam yielded significant motor and seizure control improvements. This case highlights the importance of early SSPE diagnosis and tailored interventions, shedding light on clinical progression and …

Institute for Human Development, East Africa

Neurodevelopmental disorders (NDDs) are a group of conditions with their onset during the early developmental period and include conditions such as autism and intellectual disability. Occurrence of NDDs is thought to be determined by both genetic and environmental factors, but data on the role of environmental factors for NDD in Africa is limited. This study investigates environmental influences on NDDs in children from Kenya. This case-control study compared children with NDDs and typically developing children from two studies on the Kenyan coast. We included 172 study participants from the Kilifi Autism study and 151 from the NeuroDev study who had …

Managing Refractory Epilepsy In A Resource Limited Setting—Doing More With Less, Ruta Yardi, Kurupath Radhakrishnan, Pauline Samia, Janet Wilson, Amza Ali

Paediatrics and Child Health, East Africa

Drug-resistant epilepsy (DRE) disproportionately affects individuals in low- and middle-income countries (LMIC), where access to affordable and effective care remains a significant challenge. Patients with DRE face high healthcare costs, inadequate access to epilepsy surgery, and limited availability of trained professionals. This review explores a multifaceted approach to managing DRE in resource-constrained settings. Key strategies include rational polypharmacy with cost-effective antiseizure medications (ASM), implementation of dietary therapies like the ketogenic diet, and cost-conscious presurgical evaluations. Enhancing emergency care systems, particularly for conditions like status epilepticus, is critical, as is the development of standardized diagnostic and treatment protocols and training programs …

Paediatrics and Child Health, East Africa

Children with sickle cell anemia (SCA) frequently develop progressive neurocognitive impairment. We aimed to determine effects of hydroxyurea therapy on neurocognitive function in Ugandan children with SCA by comparing levels at enrollment to a planned 18-month interim assessment. Ugandan children (N=264) ages 3-9 years were enrolled from a SCA clinic and treated in a 30-month singlearm open-label trial with escalation to maximum tolerated dose (MTD). Primary outcome was the effects of hydroxyurea on cognition, attention and executive function, along with transcranial doppler ultrasound (TCD) blood flow velocity. Sibling controls (N=110) without SCA underwent neurocognitive testing in parallel to establish age-normalized …

Pakistan Journal of Neurological Sciences (PJNS)

Houge-Janssens syndrome 1 is a rare autosomal dominant disorder with approximately 100 case reports worldwide. Here, we present a case of a Pakistani toddler who presented with epilepsy and developmental delay. Family history was significant with reported and documented developmental delays in both father and elder sister, with subsequent improvement. Trio-whole-genome sequencing (WGS) and Sanger sequencing were performed, revealing a heterozygous LP variant NM_006245.4: c.626A>C, p.(His209Pro) in the girl. The same variant was also identified in her father and sister. This case sheds light on the variability of phenotypic expression amongst affected individuals and recommends the need for further …

High Dose Methylprednisolone In Children With Severe Headache In Viral Encephalitis: A Case Series, Abia Abdullah, Jay Kumari, Prem Chand

Pakistan Journal of Neurological Sciences (PJNS)

Severe headache is a common symptom in children with viral encephalitis (VE), yet effective symptom-specific therapies are limited. In this case series, we present three children of ages 15, 14, and seven diagnosed with VE who presented with severe headaches unresponsive to standard analgesics but showed significant clinical improvement following high-dose methylprednisolone therapy. Although this is not first line treatment, these cases suggest a possible role for methylprednisolone in alleviating severe VE-associated headaches. Further controlled studies are needed to establish its effectiveness and safety in such settings.

Blood Biomarkers In Down Syndrome: Facilitating Alzheimer's Disease Detection And Monitoring, Melissa Petersen, Lisi Flores-Aguilar, Elizabeth Head, Laia Montoliu-Gaya, Andre Strydom, Sarah Pape, Juan Fortea, Nicholas Ashton, Chinedu Momoh, Sid O'Bryant

Brain and Mind Institute

Blood-based biomarkers continue to be explored for disease detection, monitoring of progression, and therapeutic outcomes as the diagnostic determination of Alzheimer's Disease in Down Syndrome (DS-AD) remains challenging in clinical settings. This perspective highlights the current status of this effort. Overall, amyloid (A), tau (T), and neurodegeneration (AT[N]) blood-based biomarkers have been shown to increase with disease pathology for individuals with DS. Phosphorylated tau biomarkers (p-tau217, p-tau181) have been consistently shown to track disease progression for DS-AD and are likely good candidates for use in clinical settings. Biomarkers of inflammation (glial fibrillary acidic protein) also show promise; however, additional work …

New Onset Seizures Evolving Into Refractory Status Epilepticus In The Setting Of Covid-19: A Case Report, Mahira Mushtaq, Zuha Amin, Shafaq Saleem, Fowzia Siddiqui

Pakistan Journal of Neurological Sciences (PJNS)

The novel Coronavirus disease (COVID-19) has been shown to involve the nervous system (both central and peripheral), with or without respiratory involvement in multiple ways. Although not much is known about this disease yet, seizures and status epilepticus which may evolve into refractory status epilepticus have been associated with it along with other manifestations like encephalopathy, neuropathies etc. The mechanism for development of seizures with COVID-19 related disease is not entirely known however it can be the consequence of “cytokine release syndrome” or “cytokine storm” which has been associated with this virus. Patients with COVID-19 infection who develop resistant status …
