Older adults in Australia who were already experiencing mental health issues before the pandemic were more likely to develop anxiety and depression during the COVID-19 crisis, according to a new study. The research found that those who were financially stressed, had poor sleep, and felt a lack of control during the pandemic were more likely to experience symptoms of depression and anxiety. Interestingly, younger adults who were already experiencing mental health issues were more likely to develop symptoms during the pandemic, while older adults who were not previously experiencing mental health issues were more likely to develop symptoms as they aged.
