The death rates due to dementia were higher in January and February of 2020 (before wave 1 of the pandemic started) than the average rates over the same period in previous years. This suggests other factors besides the pandemic may have contributed to the increased deaths due to dementia at the beginning of 2020. Knowing this, it is even more notable that during wave 2, both the death rates due to dementia and deaths with dementia were lower than rates during the same time in previous years (2015–19).
These lower death rates due to and with dementia during wave 2 of the pandemic may reflect the impact that stricter measures in place to combat the spread of the virus had on reducing the spread of other respiratory infectious diseases, which generally increase during the winter months. It may also reflect that the health and aged care system were more prepared by wave 2 of the pandemic.
