After age 75, seniors' mental health declines - especially empty-nesters

The mental health of China's senior citizens - particularly empty-nesters and those above age 75 - is not good and should get more attention, according to a report by the Chinese Academy of Sciences' Institute of Psychology.

The report, released in Beijing on Friday, found that senior citizens' mental health index drops dramatically after they turn 75.

The index, a general assessment of a person's mental status, typically rises as adults grow older, but 75 is a turning point at which things start to change, the report said.
