STROKE, SEPARATION
Thirty-five children/adolescents diagnosed with stroke between 2003 and 2018 were identified, 25 of whom agreed to participate in the study and 24 of whom met the inclusion criteria (SG). In addition, 24 individuals with typical development (CG) were included. Therefore, this study included 48 participants.The entire sample suffered a stroke between 2 and 10 years of age, and it was found that in 91.67 % of the cases, the stroke occurred in early childhood (before four years of age). All participants were evaluated in the chronic phase after stroke, with the shortest follow-up time recorded at the time of the assessments being 1 year and the longest being 12 years after stroke. Most patients were girls, and the stroke was ischemic in the left cerebral hemisphere. The epidemiological profiles of the study participants are presented in Descriptive analysis of the epidemiological profile of participants in the experimental and control groups regarding age, sex, brain region, and type of stroke.Significant differences in auditory processing were observed between children diagnosed with stroke and those with normal development.With respect to DDT, the means and standard deviations for the “integration” variable analyzed in the right ear was SG: 76.83 ± 16.35 and CG: 99.90 ± 0.50, and for the left ear were SG: 82.67 ± 15.48 and CG: 99.00 ± 1.25. A comparative intergroup analysis revealed a statistically significant difference in integration capacity (For the “separation” variable, the results for the right ear were SG: 78.83 ± 14.36 and CG: 97.70±2.69, and for the left were SG: 90.33 ± 10.43 and CG: 97.10 ± 2.47. Regarding separation, there was a significant difference in the right ear (Percentage of correct answers for the integration (A) and separation (B) variables identified by DDT for the SG and CG. (*) Significant statistical difference, The students with typical development performed better on the FPT, obtaining a higher percentage of correct answers when compared to the children and adolescents diagnosed with stroke, in both “labeling” and “humming”. The average “humming” percentages and standard deviations for the SG and CG groups were 78.83 ± 9.36 and 93.20 ± 6.49, respectively. For “labeling,” the percentage of correct answers was 46.00 ± 15.38 for the experimental group and 83.73 ± 9.30 for controls. The differences between the modalities were statistically significant (Percentage of correct answers for PPS Humming and Labeling modalities for the SG and CG. * Significantly different (Children and adolescents with typical development also performed better in the electrophysiological assessment of the P300 test, and the differences were significant for latency and similar for binaural response amplitude.The mean and standard deviations of the latency, expressed in milliseconds (ms) in the right ear, for the SG and CG, were 495.96 ± 112.91 and 306.43 ± 11.90, respectively; (For the amplitudes, expressed in microvolts (µV), the following means were obtained in the right ear for the SG and CG: 16.07 ± 6.18 and 13.15 ± 4.78 respectively; (Latency (A) and amplitude (B) measured during P300 in groups SG and CG.
