The relationship between hearing loss and Alzheimer’s disease has been studied for many years. Previous studies have shown a negative correlation between the two. In our study, we investigated the relationship between the strength of the auditory radiation connections and the severity of cognitive decline. To do so, we assessed probabilistic tractography using DTI data of the primary auditory pathway. Further, we assessed the level of cognition using the Alzheimer's Disease Assessment Scale-Cog to determine the relationship between the auditory connections assessed in each patient and that patient’s level of cognitive decline. We found that FA and AD were positively associated with cognitive decline.
