Comprehension of grammatical and emotional prosody is impaired in Alzheimer's disease.
Previous research has demonstrated impairment in comprehension of emotional prosody in individuals diagnosed with Alzheimer's disease (AD). The present pilot study further explored the prosodic processing impairment in AD, aiming to extend our knowledge to encompass both grammatical and emotional prosody processing. As expected, impairments were seen in emotional prosody. AD individuals were also found to be impaired in detecting sentence modality, suggesting that impairments in affective prosody processing in AD may be ascribed to a more general prosodic processing impairment, specifically in comprehending prosodic information signaled across the sentence level. AD participants were at a very mild stage of the disease, suggesting that prosody impairments occur early in the disease course.
