For the millions living with Alzheimer's or Parkinson's disease who also carry the weight of depression, medicine has long offered the wrong key for the lock. A landmark review in Molecular Psychiatry illuminates why: the depression that takes root in a degenerating brain is shaped by that brain's specific damage—particular circuits, particular molecular failures—not the generalized chemistry that standard antidepressants were built to address. The insight points toward a harder but more honest path, one where treatment is matched not to a symptom checklist but to the precise biology of each p

Patients with Alzheimer's and Parkinson's disease experiencing depression (35-42% of cases) currently receive ineffective treatments; precision medicine approaches could improve quality of life and slow cognitive decline, though may increase treatment costs initially.
Regulatory agencies may need to establish new approval pathways for biomarker-driven and circuit-targeted therapies; healthcare systems must invest in neuroimaging and diagnostic infrastructure; reimbursement policies may shift to support precision medicine approaches over standard antidepressants.
