Introduction: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting cortical and spinal motor neurons. There is a lack of optimal biomarkers to diagnose and prognosticate the ALS patients. C‐reactive protein (CRP), an inflammatory marker, has shown promising results in ALS patients.Materials and methods: PubMed, Embase, and Google Scholar databases were searched from 2000 to June 1, 2021 for suitable studies showing the relationship between CRP and ALS. The concentration of CRP levels was assessed between ALS patients and controls. Further, end outcomes like ALS functional rating scale (ALSFRS‐R), survival status, and mortality risks were assessed in relation to CRP levels.Results: Eleven studies including five case–control, five cohorts, and one randomized control study were assessed. There were 2785 ALS patients and 3446 healthy controls. A significant increment in CRP levels among ALS patients in comparison with healthy controls were seen in most of the studies. ALSFRS‐R and disease progression were found to be significantly correlated with CRP levels. Overall accuracy of CRP in CSF was 62% described in a single study.Conclusion: Although CRP has shown promise as a prognostic biomarker, extensive cohort studies are required to assess its prognostic value and accuracy in diagnosing ALS taking into account the confounding factors.

Background: Baseline stroke knowledge in a targeted population is indispensable to promote the effective stroke education. We report the baseline knowledge, attitude, and practice (KAP) of high school students with respect to stroke from Nepal. Materials and Methods: A self-structured questionnaire survey regarding KAP about stroke was conducted in high school students of 33 schools of Bharatpur, Nepal. Descriptive statistics including Chi-square test was used, and the significant variables were subjected to binary logistic regression. Results: Among 1360 participants, 71.1% had heard or read about stroke; 30.2% knew someone with stroke. 39.3% identified brain as the organ affected. Sudden onset limb/s weakness/numbness (72%) and hypertension (74%) were common warning symptom and risk factor identified. 88.9% would take stroke patients to a hospital. Almost half participants (55.5%) felt ayurvedic treatment be effective. 44.8% felt stroke as a hindrance to a happy life and 86.3% believed that family care was helpful for early recovery. Students who identified at least one risk factor were 3.924 times (P < 0.001, confidence interval [CI] = 1.867–8.247) or those who identified at least one warning symptom were 2.833 times (P ≤ 0.023, CI = 1.156–6.944) more likely to take stroke patients to a hospital. Conclusion: KAP of high school Nepalese students regarding stroke was satisfactory, and the students having knowledge about the risk factors and warning symptoms were more likely to take stroke patients to a hospital. However, a few misconceptions persisted.

Cerebral small vessel disease (CSVD) encompasses a broad clinical spectrum united by pathology of the small vessels of the brain. CSVD is commonly identified using brain magnetic resonance imaging with well characterized markers including covert infarcts, white matter hyperintensities, enlarged perivascular spaces, and cerebral microbleeds. The pathophysiology of CSVD is complex involving genetic determinants, environmental factors, and their interactions. While the role of vascular risk factors in CSVD is well known and its management is pivotal in mitigating the clinical effects, recent research has identified novel genetic factors involved in CSVD. Delineating genetic determinants can promote the understanding of the disease and suggest effective treatments and preventive measures of CSVD at the individual level. Here we review CSVD focusing on recent advances in the genetics of CSVD. The knowledge gained has advanced understanding of the pathophysiology of CSVD, offered promising early results that may improve subtype identification of small vessel strokes, has led to additional identification of mendelian forms of small vessel strokes, and is getting closer to influencing clinical care through pharmacogenetic studies.

With the outbreak of COVID-19 (coronavirus disease 2019) as a global pandemic, various of its neurological manifestations have been reported. We report a case of a 54-year-old male with new-onset seizure who tested positive for severe acute respiratory syndrome coronavirus 2 from a nasopharyngeal swab sample. Investigative findings, which included contrast-enhancing right posterior temporal lobe T2-hyperintensity on brain magnetic resonance imaging, right-sided lateralized periodic discharges on the electroencephalogram, and elevated protein level on cerebrospinal fluid analysis, supported the diagnosis of possible encephalitis from COVID-19 infection. The findings in this case are placed in the context of the existing literature.
