A new study is giving researchers hope that depression may someday be diagnosed with more than just questionnaires and conversations. Scientists now believe a simple blood test could help identify biological signs tied to depression, particularly emotional and cognitive symptoms that are often harder to measure.
The research focused on how certain immune cells age inside the body and found striking links between accelerated immune aging and mood-related symptoms such as hopelessness, loss of pleasure, and emotional exhaustion. Published in The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences, the findings could move mental health care closer to a future where depression is detected earlier and treated more precisely, as per a report by Science Daily.
