Hearing loss and cognition: A protocol for ensuring speech understanding in neuropsychological assessment

Many neuropsychological tests involve auditory components including test stimuli and instructions. Hearing loss may adversely affect neuropsychological performance through participants not being able to adequately understand auditory stimuli or verbal instructions, thus hampering identification and accurate classification of cognitive impairment. Formal measures to quickly assess speech understanding are lacking. Herein, we describe a protocol developed to determine adequate speech understanding and report on the relationship between hearing loss and speech understanding performance.
