Lower risk of depression, dementia after getting hearing aids

Older adults who get hearing aids for a newly diagnosed hearing loss have a lower risk of being diagnosed with dementia, depression, or anxiety for the first time over the next three years. Getting a hearing aid is also linked to a lower risk of suffering fall-related injuries than those who leave their hearing loss uncorrected, a new study finds. Yet only 12% of those who have a formal diagnosis

Scientists also found that infection causes long-lasting learning and memory deficits in adult mice. The results demonstrate that the adult brain (and not only the developing brain, as previously thought) is attacked and damaged by ZIKV, and indicate the need to investigate memo
