14 Speech Perception

15 Cognition and Hearing Loss 1999-2011, Frank R. Lin Audiometric Evaluation & DSST component of the Wechsler Adult Intelligence Test

16 Cognition and Hearing Loss 2014, University of Hong Kong Assessed: Pure-tone audiometry Hearing in Noise Test Mini Mental State Evaluation (MMSE) Orientation to time Orientation to place, Registration Attention calculations Recall, Language Repetition Complex commands

17 Auditory Deprivation

18 Treatment Aural Rehabilitation Amplification Hearing aids Bone anchored hearing aid (BAHA) Cochlear Implant Communication Therapy

19 Cognitive Improvements 2011, Kalluri & Humes Short-Term Interactions of Hearing Technology and Cognition Noise recall, neurological fatigue, auditory function Long-Term Impact of Hearing Technology and Cognition Diminishing sensory input

20 Cognitive Improvements 2010, Eulji University School of Medicine Speech related cognition Statistically significant Speech discrimination in background noise Not statistically significant

21 Cognitive Improvements 2005, International Journal of Audiology No statistical significance

22 My Future Studies “Window of opportunity” Degree of hearing loss Age impact on cognitive improvement with hearing aids
