Scientists have demonstrated the possibility of detecting dementia from conversations in human-agent interaction. Their research shows how a machine can learn characteristics of sounds of elderly people who answered easy questions from avatars on a computer.

Older adults fitted with a cochlear implant to compensate for severe hearing loss have significantly poorer cognitive function than their normal-hearing counterparts. Hearing loss is a risk factor for cognitive decline, so this new finding suggests cochlear implants cannot fully…

Obesity leads to cognitive impairment by activating microglial cells, which consume otherwise functional synapses in the hippocampus, according to a study of male mice. The research suggests that microglia may be a potential therapeutic target for one of the lesser…
