Therefore, mathematical calculations on clinical IS symptoms in children of different ages are crucial for confirming the disease and initiating early treatment. Table 2 illustrates the clinical manifestations of stroke according to age. \begin{table}

Table 2: Clinical manifestations of IS in newborns and children (Number of cases = 148), abs., %. Further studies are required to confirm the diagnosis of stroke. Imaging findings, including brain CT scans, often do not reveal the presence of brain injury, largely depending on the timing of the examination. MRI scanning of the brain allows an assessment of the pathological focus topography and volume. During the study, it was observed that in newborns, the anterior cerebral artery and the middle cerebral artery were primarily affected, accounting for 228 cases (63.0%; 95% CI 60.46-65.54), along with the left cerebral hemisphere in 245 cases (67.7%; 95% CI 65.24-70.16). Multifocal brain injuries were identified in one-third of the children, totaling 119 cases (32.9%; 95% CI 30.43-35.37). Throughout the study, a wide range of outcomes was observed among patients in the acute phase of the disease, reflecting varying degrees of severity from mild to severe symptoms, often resulting in severe neuro-psychomotor impairment (Table 3). Of the 108 children examined, 82 (75.9%; 95% CI [71.79-80.01]) presented motor deficits, 45 (41.7%; 95% CI [36.96-46.44]) had convulsions, and 19 (17.6%; 95% CI [13.94-21.26]) experienced impaired consciousness. Additionally, among these children, 87 (80.6%; 95% CI [76.79-84.41]) had a unilateral stroke, and 77 (71.3%; 95% CI [66.95-75.65]) showed signs of middle cerebral artery injuries. The degree of neurological manifestations was assessed using the Amiel-Tison and Gosselin summary tables (classified as shown in Table 3) and the PedNIHSS scale. The mean value of the PedNIHSS scale was 7.8 points, with the scale ranging from 0 to 17 points. The statistical results of the calculated tests (\(\chi^{2}\) = 13.923, df = 4, and \(p\) < 0.01) were significant. The majority of children with IS exhibited a mild to moderate IS severity, with 89 cases (82.4%; 95% CI [78.74-86.06]) falling within this range. The results obtained from the assessment of the Amiel-Tison, Gosselin, and PedNIHSS
