Summary (paraphrased)
Clinical studies indicate that former users of 5-alpha-reductase inhibitors carry a higher incidence of depressive symptoms and neuropsychiatric side effects than non-users, yet the mechanisms behind depression in former users — sometimes called post-finasteride syndrome — remain poorly understood. This review pulls together the association between 5-AR inhibitors and depression alongside candidate mechanisms, with emphasis on neurosteroid depletion and downstream effects on GABAergic and neurotrophic signaling. The authors note that the persistence of depressive symptoms after the drug is stopped points to lasting neurobiological changes rather than a transient pharmacologic effect. The paper is a PubMed-based literature synthesis rather than original research.
Why it’s in the corpus
Explicitly centers the depression-withdrawal link that the corpus tags heavily, and frames persistence as a lasting neurobiological change — directly on the neurosteroid/GABA-A axis.

This major review reconsiders progesterone and its 5-alpha-reduced metabolite allopregnanolone as central nervous system signaling molecules rather than mere reproductive hormones. It covers their synthesis in the brain, their potentiation of GABA-A receptor…
