There is increasing and compelling evidence to suggest that brains weakened by either age or illness process auditory information slower than healthy ones.
Since a strong brain is essential for good hearing, diminished cerebral functions can result in poor auditory processing abilities, especially in older people.
This is especially true in situations where several conversations are carried out simultaneously. Listening and interpreting such mix of competing sounds is difficult even for those with normal hearing; for the hearing-impaired, it is all the more challenging.
However, various scientific studies demonstrate that "exercising" our brains with specially-devised mental "workout" routines, allow even older people to boost their cognitive abilities, including better hearing and speech interpretation.
There are many brain boosting exercises to choose from, including the six-step PositScience Brain Fitness computer program that uses cutting-edge research in neuroscience to increase brain plasticity and auditory processing skills.
And as in every exercise regimen, healthy nutrition also goes a long way in bolstering the brainpower. Good "brain" foods include whole grains, protein, fruits and vegetables, and keep foods with refined sugar and saturated fat to a minimum.
