Abstract
PURPOSE This study investigated EEG alpha rhythm spectral power in children with Specific Language Impairment (SLI) and compared it to typically developing children to better understand the electrophysiological characteristics of this disorder. Specifically, we explored resting-state EEG, because there are studies that point to it being linked to speech and language development. METHODS EEG recordings of 30 children diagnosed with specific language impairment and 30 typically developing children, aged 4.0-6.11 years, were carried out under eyes closed and eyes open conditions. Differences in alpha rhythm spectral power in relation to brain topography and experimental conditions were calculated. RESULTS In the eyes closed condition, alpha rhythm spectral power was statistically significantly lower in children with specific language impairment in the left temporal (T5) and occipital electrodes (O1, O2) than in typically developing children. In the eyes open condition, children with SLI showed significantly lower alpha rhythm spectral power in the left temporal (T3, T5), parietal (P3, Pz), and occipital electrodes (O1, O2). There were no statistically significant differences between the groups in relation to the relative change (the difference between average alpha rhythm spectral power during eyes closed condition and average alpha rhythm spectral power during eyes open condition divided by average alpha rhythm spectral power during eyes closed condition) in the alpha rhythm spectral power between the conditions. CONCLUSION Lower alpha rhythm spectral power in the left temporal, left, midline parietal, and occipital brain regions could be a valuable electrophysiological marker in children with SLI. Further investigation is needed to examine the connection between EEG alpha spectral power and general processing and memory deficits in patients with SLI.

Abstract
BACKGROUND 22q11.2DS is the most common microdeletion syndrome in humans, usually associated with speech and language delay (SLD). Approximately 75% of children with 22q11.2 microdeletion have congenital heart malformations (CHM) which after infant open-heart surgery might lead to SLD. AIMS The purpose of this study was to determine whether factors associated with microdeletion contribute to SLD in children with 22q11.2DS. METHODS AND PROCEDURES We compared speech and language abilities of two groups of school-aged children: those with 22q11.2 microdeletion (E1) and those with the phenotype resembling 22q11.2DS but without the microdeletion (E2). An age-matched group of typically developing children was also tested. OUTCOMES AND RESULTS The obtained results revealed that children from group E1 have lower level of speech and language abilities compared to children from group E2 and control group. Additionally, mild to moderate SLD was detected in children from group E2 compared to children from the control group. CONCLUSIONS AND IMPLICATIONS The obtained results imply that both CHM after infant open-heart surgery and other factors associated with 22q11.2 microdeletion, contribute to SLD in patients with 22q11.2 microdeletion. Based on this, we could postulate that there is/are some potential candidate gene(s), located in the 22q11.2 region, whose function could be important for speech and language development.

Abstract
Objective:This study was a 15-year follow-up examination. Many patients with F 62.0 and post traumatic stress disorder (PTSD) have symptoms of depression. The authors’ objective is to analyze symptoms of depression in F 62.0 and PTSD.Method:The subjects were 200 male psychiatric patients at a Clinic of psychiatry medical center Banjaluka and psychiatry department of with war-related PTSD. Post traumatic stress syndrom-PTSS scale and 21-item Hamilton Rating Scale for Depression-HAMD was used to assess state measures of symptom severity; from 3 months to 15 years after returning from the war.Results:The symptoms of prolonged PTSS (with duration between six moths and two years) had been founded at 54%, and 32% of patients had no diagnosis PTSD. The enduring personality change after catastrophic experience (F 62.0) had been found at 14% patients (with duration more than two years), 19% met HAMD Diagnostic Criteria for major depressive disorder.The enduring personality exchange F 62.0 had been found at 8% patients and 16% met HAMD Diagnostic Criteria for major depressive disorder 15 years after returning from the war.Conclusions:The statistical relationship between level of combat exposure and PTSD symptoms at 15 years, suggests that it may take time for the consequences of traumatic exposure to become apparent. Moreover, degree of exposure may be important in predicting the eventual development of symptoms and precipitation of F 62.0 enduring personality exchange. Continued follow-up will address the evolution of PTSD symptoms in war related PTSD.
