The Claim
In adults aged 50 and older with confirmed COVID-19 infection, pre-existing depression is not significantly associated with the overall likelihood of developing any long COVID symptom, but is associated with a higher number of symptoms among those who develop long COVID.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Among adults aged 50 and older who had confirmed COVID-19, those with pre-existing depression are not more likely to develop long COVID than those without depression, but they tend to experience more symptoms if they do develop long COVID.

In adults aged 50 and older with confirmed COVID-19 infection, pre-existing depression is not significantly associated with the overall likelihood of developing any long COVID symptom, but is associated with a higher number of symptoms among those who do develop them.
People with a history of depression have a brain and immune system that are already in a heightened state of inflammation and stress signaling. When they get infected with COVID-19, this existing state causes the body to overreact, leading to more widespread tissue irritation and nerve signaling problems, which results in more symptoms like pain, fatigue, and brain fog — even though it doesn’t make them more likely to get long COVID at all.
What the research says
1 studyPeople who were depressed before getting COVID aren’t more likely to get long COVID, but if they do get it, they tend to have more symptoms like headaches and body aches than others.
