New York University news release

Blood tests measuring the aging of certain white blood cells can predict cognitive and mood-related symptoms of depression, rather than physical symptoms.

Depression is diagnosed based on self-reported symptoms. While clinicians may run blood tests to rule out other health conditions, researchers have yet to identify an objective diagnostic biomarker that can signal early on that someone is experiencing depression.

Depression is more common in people with certain disorders that affect the immune system, including HIV. This may be a result of intersecting factors such as chronic levels of inflammation, stigma, and socioeconomics. Women with HIV have particularly high rates of depression, which can make it more difficult for them to engage in treatment and adhere to antiretroviral therapy.

To explore the biological underpinnings of depression in women with and without HIV, the researchers looked at measures of accelerated biological aging, which have been linked to both depression and HIV.
