Changes in Cerebellar and Frontal Cortex Predict Age-related Changes in Cognitive Processing Speed
The most consistent and pronounced factor that affects the cognitive abilities of older adults is a decline in processing speed, or the rate at which people can perform a task. Links between processing speed and changes in frontal lobe cortex, which appear to be mediated in part by cerebral vessel disease, have been reported previously.…

Age-related differences in auditory gap detection predicted by cognitive processing speed
Changes in auditory temporal processing are thought to be one reason why older adults have difficulty recognizing speech, especially in difficult listening conditions. Dr. Kelly Harris reports in the journal Hearing Research that changes in auditory temporal processing can be explained, in part, by changes in cognitive processing speed. Processing speed is the rate at…

Society for Neuroscience Press Release: Age-related difficulty recognizing words predicted by brain differences
Findings show speech recognition problems independent of hearing loss Washington, DC May 12, 2009 – Older adults may have difficulty understanding speech because of age-related changes in brain tissue, according to new research in the May 13 issue of The Journal of Neuroscience. The study shows that older adults with the most difficulty understanding spoken…
