![]() ![]() Risk factors include exposure to blast, neurotrauma, hazardous noise, and ototoxicants. We will also conduct similar to the auditory, visual evoked responses to assess whether any electrophysiological abnormalities are specific to the auditory modality. Purpose A growing body of evidence suggests that military service members and military veterans are at risk for deficits in central auditory processing. We will compare these responses in the two groups to see if these are different and we will examine which response parameters and criteria are best in differentiating APD from non-APD children, and with what percentage of correct and false diagnostic hit rate (sensitivity and specificity). ![]() We will conduct auditory cortical evoked responses (EEG) and behavioural tests in 30 children with a diagnosis of APD from the Great Ormond Street Hospital Audiological Medicine clinic, and on 30 age and sex matched normal controls. To identify the brain parts (identified by analysing which parts of the top brain generate the auditory cortical responses -EEG ) that underpin test performance and clinical symptoms. normal age matched children, and if so, how good this test is in diagnosing APD.Īims: To identify impairment(s) underlying an APD and behavioural/EEG test paradigms for APD assessment that can be used in the clinic. This study will investigate if the electrical activity of the top part of the brain in response to complex sounds (ie “auditory cortical evoked responses“ referred to as EEG) is different in children with APD vs. APD is diagnosed on the basis of hearing tests that require a response from the child (behavioural or subjective), tests that assess the brain’s activity in response to sound (electrophysiological or “objective“) and additional assessments of language and cognition. Auditory Processing Disorder (APD) is a hearing/listening disorder resulting from abnormal brain function that may be associated with communication, learning, behavioural, emotional, and social difficulties. ![]()
