Study finds five distinct brain patterns behind depression

· Science

Researchers studying 263 people with depression identified five distinct brain profiles, each showing different patterns of communication between brain regions and associations with particular symptoms. The finding supports the view that depression may not be one biological condition but several different patterns of brain activity hiding under the same diagnosis. If confirmed, such profiles could eventually guide more precise treatment selection, moving psychiatry away from trial-and-error prescribing toward biologically informed subtyping. The work is part of a broader effort to find measurable biomarkers for mental illness, though translating brain-imaging profiles into routine clinical practice remains an open challenge.

Why it matters：It strengthens the case for biologically subtyping psychiatric diagnoses, which could reshape how treatments are matched to patients and how trials are designed.

Key points

  • The study examined 263 people with depression.
  • Five brain profiles were identified, each with different patterns of communication between brain regions.
  • The profiles were linked to different symptoms.
