An image of an older gentleman holding a phone up to his ear. He might have trouble processing speech.

Processing speech is essential to understand others. How does it affect the elderly?

As we get older, we begin to worry more and more about our bodies. What is ailing us and what will fail next? These are the questions that many of us have. For that very reason, scientists look into how our bodies operate to get not only a better understand but to fix our illnesses. The American Physiological Society performed a recent study examining the causes of age-related hearing loss and difficulties processing speech. Here is what they found.

Processing Speech Deteriorates

Processing speech is important. It helps us communicate effectively with others, especially when the volume changes in an area. Your hearing adapts to understand what someone is saying in noisy or quiet areas. A lot of what controls your hearing has to do with the brain. And when the brain malfunctions, your senses go as well.

The scientists at the American Physiological Society suspected that a decline in midbrain and cortical activity are responsible for hearing loss. So, they tested two groups using an electroencephalogram to measure mid-brain activity, and a magnetoencephalogram to measure the cortical activity. A group of younger adults around the age of 22 and another group of older individuals around the age of 65.

As expected, the older groups experienced difficulties processing speech. The environments noise level did not matter. Whether it was loud or quiet, the older group had trouble while the younger group took less time processing cues and speech. And these results show in the same in their brains.

The activity in the midbrain and cortex was low, showing that the health of these key areas is necessary to function. They help us process speech and understand others effectively. Hopefully, further research can tell us more. Aging can be difficult but it doesn’t have to stop us from living life. Maybe, it will be a sign to older adults to seek alternate options to hear from their physician.
