Landau-Kleffner Syndrome (LKS) is a rare, childhood neurological disorder characterized by a sudden or gradual development of acquired aphasia. This case study offers a unique opportunity to assess the changes in the auditory processing ability of a 12 year old male with LKS after two distinct auditory training programs, Fast ForWord® and Dichotic Interaural Intensity Difference (DIID) training...

Three experiments examined the effect of gaze shifts on overall performance and ear differences in dichotic listening. In the first two experiments, lights were switched on and off so as to induce rightward, leftward, or upward gaze during dichotic stimulation. The dichotic material consisted of musical passages in Experiment 1 and two kinds of verbal material in Experiment 2. Vertical eye move...

OBJECTIVES To describe magnetic resonance imaging characteristics in a large sample of subjects with mild cognitive impairment (MCI) and to investigate associations between these characteristics and cognition. DESIGN Cohort study. SETTING Baseline data of a randomized, double-blind, placebo-controlled clinical trial of galantamine in MCI. PATIENTS Included in the study were 896 subjects w...

INTRODUCTION Evaluation of the objective results in the clinical examination of central auditory disorders requires the use of reliable language tests which provide the means for the estimation of patients' audio-verbal communicative skills. MATERIALS AND METHODS The authors present a new set of more difficult language tests in Polish, including a filtered speech test, numeral and verbal dich...

OBJECTIVE To confirm that central auditory dysfunction (CAD) may be a precursor to the onset of Alzheimer dementia (AD). DESIGN Cohort study. SETTING Research study center. PARTICIPANTS Two hundred seventy-four volunteers from a dementia surveillance cohort were followed up for as long as 4 years after undergoing complete audiometric assessment. Twenty-one received a consensus diagnosis o...

Over the past two decades, a number of studies have been based on the dichotic temporal order judgment (TOJ) paradigm, to compare auditory temporal processing in various subpopulations to that of young, normal controls. The reported estimates of dichotic TOJ thresholds, expressed as the interstimulus intervals (ISIs) for 75 % accuracy among the controls, have varied. In the present study, we ex...

The objective of this study was to develop and evaluate the Polish digit triplet test for speech intelligibility screening. The first stage of the work deals with the preparation of the test and the recording procedure. The second part presents results of the digit triplets intelligibility measurement and retest data. The test consists of 4 statistically equivalent and phonemically balanced lis...

Individuals with MCI declined in performance over 6 months in the Clock-drawing (Clox 1) and the WAIS Digit Span tests, but not in the Dementia Rating Scale (DRS). Individual performance on Clox 1 and Digit Span did not correlate after 6 months. Performance on the Digit Span Test also did not correlate with the DRS, but performance on Clox 1 correlated with the DRS. Performance in Clox 1 was, t...
