Background and Aim: In most everyday settings, speech is heard in the presence of competing sounds and speech perception in noise is affected by various factors, including cognitive factors. In this regard, bilingualism is a phenomenon that changes cognitive and behavioral processes as well as the nervous system. This study aimed to evaluate speech perception in noise and compare differences in Kurd-Persian bilinguals versus Persian monolinguals.
Methods: This descriptive-analytic study was performed on 92 students with normal hearing, 46 of whom were bilingual Kurd-Persian with a mean (SD) age of 22.73 (1.92) years, and 46 other Persian monolinguals with a mean (SD) age of 22.71 (2.28) years. They were examined by consonant-vowel in noise (CV in noise) test and quick speech in noise (Q-SIN) test. The obtained data were analyzed by SPSS 21. Results: The comparison of the results showed differences in both tests between bilingual and monolingual subjects. In both groups, the reduction of signal-to-noise ratio led to lower scores, but decrease in CV in noise test in bilinguals was less than monolinguals (p < 0.001) and in the Q-SIN test, the drop in bilinguals’ score was
more than monolinguals (p = 0.002).
Conclusion: Kurd-Persian bilinguals had a better performance in CV in noise test but had a worse performance in Q-SIN test than Persian monolinguals.
Background and Aim: Vestibular rehabilitation is suggested as one of the effective treatments for vestibular-originated dizziness and vertigo. As there is a proven biologic link between vestibular symptoms and headache, headache improvement with vestibular improvement after vestibular rehabilitation is expected. The aim of the present study was examining vestibular rehabilitation effects on dizziness and headache in 9−15 year old subjects with a vestibular migraine.
Methods: Eight subjects with vestibular migraine were referred to Rofeideh Rehabilitation Hospital after diagnosis by a pediatric neurologist. They were evaluated via dizziness handicap inventory (DHI), headache impact test-6 (HIT-6) and dizziness and headache frequency. Then they received a home-based vestibular rehabilitation and after one month they were reevaluated.
Results: After vestibular rehabilitation for one month, changes in the DHI and HIT-6 score were statistically significant (p < 0.01). In addition, reduction in the dizziness and headache frequency in a month was statistically
significant.
Conclusion: As vestibular rehabilitation has noticeable effects on dizziness and headache, this treatment is introduced as an effective and non-invasive treatment in children and adoles-cents with a vestibular migraine.
