INTRODUCTION AND OBJECTIVES Hyperhomocysteinemia as a risk factor for hearing impairment, neuronal damage and cognitive impairment in elderly patients is controversial and is limited by the small number of studies. The aim of this work was determine if elderly patients detected with hyperhomocysteinemia have an increased risk of developing abnormalities in(More)
OBJECTIVE Dyslexia is the difficulty of children in learning to read and write as results of neurological deficiencies. The objective was to test the Phonological awareness (PA) and Sinusoidal amplitude modulation (SAM) threshold in children with Phonological dyslexia (PD). METHODS We performed a case-control, analytic, cross sectional study. We studied(More)
OBJECTIVE Compare if localization of sounds and words discrimination in reverberant environment is different between children with dyslexia and controls. METHOD We studied 30 children with dyslexia and 30 controls. Sound and word localization and discrimination was studied in five angles from left to right auditory fields (-90o, -45o, 0o, +45o, +90o),(More)
OBJECTIVE We hypothesized that if the right hemisphere auditory processing abilities can be altered in children with developmental dyslexia (DD), we can detect dysfunction using specific tests. METHOD We performed an analytical comparative cross-sectional study. We studied 20 right-handed children with DD and 20 healthy right-handed control subjects (CS).(More)
OBJECTIVE To identify the natural tendencies of hits and calculate the cutoff for a test group of central auditory processes (CAP): binaural fusion, filtered words, dichotic digits, frequency patterns and duration patterns and ambient sounds in normal 5-, 7-, 9- and 11-year-old children. MATERIAL AND METHODS We studied 369 children (738 ears) who attend(More)
OBJECTIVES The aim is to assess the ability to discriminate words, using two psychoacoustic verbal tests of central auditory processes in Spanish: Binaural Fusion Test (BFT in its Spanish version) and Filtered Word Test (FWT in its Spanish version) in children with dyslexia and controls. METHODS One group of 40 dyslexic children was receiving therapy for(More)
AIM To evaluate the results obtained from applying the monaural compressed speech test in Spanish at 75% and 100% in cases of stutterers and controls. SUBJECTS AND METHODS The study involved 50 cases with ages ranging from 8 to 36 years, 25 of whom were stutterers and 25 controls, who were paired one to one by age, sex and schooling. Severe cases of(More)
INTRODUCTION AND OBJECTIVE To identify the auditory or clinical test that has the best correlation with the ear in which we apply the monaural hearing aid in symmetric bilateral hearing loss. MATERIAL AND METHOD A total of 37 adult patients with symmetric bilateral hearing loss were examined regarding the correlation between the best score in speech(More)
AIMS In children with articulatory defects it is important to evaluate the central auditory level. We compared the results of the interwave intervals of brainstem auditory evoked potentials (BAEP) at 80 dB SPL (sound pressure level) and the latencies of the waves of long latency auditory evoked potentials (LLAEP) (vertex) in 5-year-old children with(More)
INTRODUCTION In this study, a new dichotic digit test in Spanish (NDDTS) was applied in order to identify auditory laterality. We also evaluated body laterality and spatial location using the Subirana test. SUBJECTS AND METHODS Both the dichotic test and the Subirana test for body laterality and spatial location were applied in a group of 40 children with(More)
