Background Epileptiform activities can cause transient or permanent deficits that affect the children during development and may be accompanied by neurodevelopmental disorders like specific language impairment. Objectives The objective of this study was to find if there is a possible association and the impact of epilepsy and epileptiform activity in children with specific language impairment. Patients and methods The study was conducted on 80 children suffering from specific language impairment and 80 age and sex match healthy control children. Computed tomography brain was performed and electroencephalography was recorded for children. Intelligence quotient level, cognitive age, social, and phoniatric assessment were done for all patients. Results Eighty children with specific language impairment (51 males and 29 females) with a mean age of 4.11 ± 1.93. Patients with specific language impairment showed significantly higher rates of abnormal electroencephalography (P = 0.006) and epilepsy (P < 0.001) compared to the control group. Spearman correlation demonstrated a highly negative significant relationship linking the language, intelligence quotient with abnormal electroencephalography and epilepsy (r = − 0.91, P < 0.01 and r = − 0.91, P < 0.01 respectively). Also, there was a moderately inverse significant relationship linking the cognitive age, social with abnormal electroencephalography, and epilepsy (r = − 0.70, P < 0.05 and r = − 0.65, P < 0.05 respectively). Conclusion Epileptiform activities even without epilepsy in preschool children may alter normal language function. Specific language impairment was associated with lower intelligence quotient levels, social, and cognitive age. Trial registration ClinicalTrials.gov ID: NCT04141332

The head-on collision between two quantum dust-acoustic solitary waves (QDASWs) in ultradense astrophysical objects has been investigated theoretically using the extended Poincaré-Lighthill-Kuo (PLK) method. The Korteweg-de Vries equations and the analytical phase shifts after the head-on collision of the two QDASWs in quantum dusty plasmas are obtained. Numerically, the obtained results demonstrate that the dust size distribution, the quantum corrections of diffraction and the temperatures of electrons and ions have strong effects on the nature of the phase shifts and the trajectories of the two QDASWs after collision.

Aim: To develop a time-efficient Arabic test battery for adult-onset chronic aphasia that provides information about the type and the severity of the disorder. Patient and Methods: A total of 90 participants were recruited and divided into 3 groups. The groups consisted of 30 adult-onset post-stroke chronic aphasic patients, 30 adult non-aphasic adults with central neurological disorders, and a group of 30 non-brain-damaged healthy adults. All participants were assessed using the Mansoura Arabic Screening Aphasia Test (MASAT), which consists of 4 main sections: (1) language expression abilities including repetition and naming items, (2) language comprehension questions, (3) fluency, and (4) reading, writing and calculation items. The content validity, internal consistency, clinical validity, and convergent validity of the MASAT were evaluated. Results: The MASAT demonstrated statistically high reliability and validity. The high α-values in all subtotal scores among the 3 groups were judged to denote excellent intercorrelation among the screening test items. Conclusion: The MASAT is a valid and a reliable brief assessment tool that can be completed on the first clinic appointment that detects the type and severity of Arabic-speaking aphasic patients.
