Effect of Mild Cognitive Impairment and Alzheimer Disease on Auditory Steady-State Responses
Introduction: Mild Cognitive Impairment (MCI), a disorder of the elderly people, is difficult to diagnose and often progresses to Alzheimer Disease (AD). Temporal region is one of the initial areas, which gets impaired in the early stage of AD. Therefore, auditory cortical evoked potential could be a valuable neuromarker for detecting MCI and AD. Methods: In this study, the thresholds of...
متن کاملTutorial Auditory Steady - State Responses
Background: The auditory steady state response (ASSR) is an auditory evoked potential (AEP) that can be used to objectively estimate hearing sensitivity in individuals with normal hearing sensitivity and with various degrees and configurations of sensorineural hearing loss (SNHL). For this reason, many audiologists want to learn more about the stimulus and recording parameters used to successfu...
متن کاملNeuromagnetic steady-state responses to auditory stimuli.
Steady-state magnetic responses to clicks presented at rates between 10 and 70 Hz have been recorded in healthy humans. The responses were highest in amplitude around 40 Hz. This amplitude enhancement is satisfactorily explained by summation of responses evoked by single clicks. The field maps suggest activation of the auditory cortex at all stimulus frequencies. Similar responses were obtained...
متن کاملAttentional Modulation of Auditory Steady-State Responses
Auditory selective attention enables task-relevant auditory events to be enhanced and irrelevant ones suppressed. In the present study we used a frequency tagging paradigm to investigate the effects of attention on auditory steady state responses (ASSR). The ASSR was elicited by simultaneously presenting two different streams of white noise, amplitude modulated at either 16 and 23.5 Hz or 32.5 ...
متن کاملAuditory steady-state responses and speech feature discrimination in infants.
PURPOSE The aim of this study was to determine whether there was a correlation between auditory steady-state responses (ASSRs) for complex toneburst stimuli and speech feature discrimination (SFD) abilities in young infants. STUDY SAMPLE Seventeen infants (mean age = 9.4 months) and 21 adults (mean age = 27 years) with normal hearing had ASSR and SFD tests. DATA COLLECTION The ASSR test emp...
