Readers of the publication Trends in Neurosciences will already know today’s fact. For the other 99.9 percent of us, though, it is definitely interesting.

According to a story in the June 2016 edition, research has confirmed that “even relatively mild levels of hearing loss” can lead to cascading negative effects on the brain. Those effects can impact perception, comprehension and memory.

The thinking goes: the more effort it takes to listen and piece together what someone is saying (due to hearing loss), the more it impacts other cognitive operations, “such as remembering what has been heard.” It’s one huge reason why experts at Johns Hopkins recommend treating hearing loss sooner rather than later.
