Multiple sclerosis (MS) is a chronic autoimmune disease that impacts the central nervous system and can result in disability. Although the prevalence of MS has increased in India, diagnosis and treatment continue to be difficult due to several factors. The present study examines the difficulties in detecting and treating multiple sclerosis in India. A lack of MS knowledge among healthcare professionals and the general public, which delays diagnosis and treatment, is one of the significant issues. Inadequate numbers of neurologists and professionals with knowledge of MS management also exacerbate the situation. In addition, MS medications are expensive and not covered by insurance, making them inaccessible to most patients. Due to the absence of established treatment protocols and standards for MS care, India’s treatment techniques vary. In addition, India’s population diversity poses unique challenges regarding genetic variations, cellular and molecular abnormalities, and the potential for differing treatment responses. MS is more difficult to accurately diagnose and monitor due to a lack of specialized medical supplies and diagnostic instruments. Improved awareness and education among healthcare professionals and the general public, as well as the development of standardized treatment regimens and increased investment in MS research and infrastructure, are required to address these issues. By addressing these issues, it is anticipated that MS diagnosis and treatment in India will improve, leading to better outcomes for those affected by this chronic condition.

“…Das Halbfeld-VEP stellt ein Summationsbild des oberen und unteren Quadranten sowie des makularen NPN-und paramkularen PNP-Komplexes dar, wobei der makulare Anteil dominiert. Ein Ausfall der Fovea führt zu einer Demaskierung des paramakularen PNP-Komplexes (7, 15,28,32). Phaseninversionen von Komponenten des VEP können sowohl bei Reizung mit großen als auch bei Reizung mit kleinen Mustern beobachtet werden, wobei bei den Ableitungen mit großen Reizrnustem meist nur die frühen Komponenten mit Latenzen zwischen 50 und 70 ms betroffen sind.…”

“…Visual evoked potential (VEP) is recording the visual pathway electrical activity from the calcarine cortex to the optic nerve (Baiano & Zeppieri, 2023). Since having a healthy functional visual pathway from the retina to the cortex is essential for a normal VEP, demyelinating disorders can cause amplitude and latency abnormalities (Steczkowska et al., 2009; Tsoumanis et al., 2023).…”

IntroductionGeneralized joint hypermobility (GJH) can be the result of several hereditary connective tissue disorders, especially Ehlers–Danlos syndrome. Cerebrovascular manifestations are among the most common complications in this disorder, and understanding their extent can help better diagnosis and prevention of hazardous events. We investigated visual evoked potential (VEP) changes in patients with GJH and compared them with healthy individuals.MethodsOur case–control study included 90 patients who fulfilled the Beighton score (B score) for joint hypermobility and other 90 healthy participants. All of them went under VEP study, and the amplitude and latency of the evoked potential (P100) were compared to each other.ResultsThe Case group had significantly higher B score (7.18 ± 0.967 vs. 1.18 ± 0.712), P100 latency (110.23 ± 6.64 ms vs. 100.18 ± 4.273 ms), and amplitude (6.54 ± 1.26 mv vs. 6.50 ± 1.29 mv) compared with the Control group, but the difference was only significant regarding B score, and P100 latency (p‐value <.0001). Moreover, both latency and amplitude of P100 had significantly positive correlations with the B score in the Case group (p‐value <.0001), but such correlations were not found in the Control group (p‐value = .059).ConclusionOur study could reveal VEP changes, especially significant P100 latency in GJH patients without previous neurologic or musculoskeletal disorders. Whether these changes are due to GJH itself or are predictive of inevitable neurologic disease or visual pathway involvement, particularly Multiple Sclerosis needs further investigation with longer follow‐up periods.
