Dichotic listening processing in patients with multiple sclerosis

Abstract

Background and Aim: Dichotic listening dis­orders occur secondary to interhemispheric tran­sfer dysfunction. Central processing tests such as staggered spondaic words (SSW) and dich­otic digits test (DDT) are recommended for the evaluation of dichotic listening in patients with multiple sclerosis (MS). The present study aim­ed to evaluate dichotic listening in subjects with MS by SSW and DDT.
 Methods: This cross-sectional study was con­ducted on 45 patients with MS, including 20 males (mean ± SD age: 35.95 ± 5.73 y) and 25 females (mean ± SD age: 37.40 ± 6.1 y) and their data were collected by the Persian version of SSW (P-SSW) and DDT. The results com­pared to 45 normal subjects age- and gender-matched as the control group.
 Results: In patients with MS, P-SSW quanti­tative and qualitative errors (except for Sm2 and reversals), errors were significantly more than the control group (p ≤ 0.001). Right and left ear scores in DDT for the patients with MS were significantly lower, and right ear advantage was significantly higher than that in the control group (p ≤ 0.001). The results also showed a significant correlation between the test of P-SSW and DDT in the left ear.
 Conclusion: The present study showed that patients with MS hav

 e lower performance in dichotic listening and binaural processing than normal peers. Identification of binaural proce­ssing deficit in patients with MS may lead to early rehabilitation and improving their function by facilitating auditory processing.

Behavioral assessment of auditory processing in adulthood: population of interest and tests - a systematic review

“…The criteria that led to the constitution of the "case group" are diverse and reflect conditions and/or characteristics that have already been described as etiological or comorbid factors for CAPD. This fact is justified because there is an etiological heterogeneity for CAPD (1) , which has been documented in cases of chronic metabolic (24,33) , vascular (59) , demyelinating (25) , hormonal (20) , psychiatric (28) , sleep (57) , learning (32) , and fluency disorders (27,29) .…”

“…The main focus of studies with CAP behavioral tests in young and middle-aged adults compared the auditory mechanisms as a function of a specific condition or pathology (e.g., diabetes mellitus, tinnitus, noise exposure, multiple sclerosis, stuttering, among others), usually with better performance by the healthy population (23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) . The approach to increasing age has been less explored, especially in adults without hearing loss.…”

Avaliação comportamental do processamento auditivo na idade adulta: população de interesse e testes - uma revisão sistemática

“…Os critérios que conduziram à constituição do "grupo caso" são diversos e refletem condições e/ou características que já foram descritas como fatores etiológicos ou comórbidas ao TPAC. Este fato se justifica uma vez que existe uma heterogeneidade etiológica para o TPAC (1) , já documentada nos casos de desordens metabólicas crônicas (24,33) , vasculares (59) , desmielinizantes (25) , hormonais (20) , psiquiátricas (28) , do sono (57) , de aprendizagem (32) e de fluência (27,29) .…”

“…O principal enfoque dos estudos com testes comportamentais do PAC em adultos jovens e de meia idade comparam os mecanismos auditivos em função de uma condição ou patologia específica (e.g. diabetes mellitus, zumbido, exposição a ruído, esclerose múltipla, gagueira, entre outros) usualmente com melhor desempenho para a população hígida (23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) . O enfoque do aumento da idade é menos explorado, principalmente em adultos sem perda auditiva.…”
