Post-Finasteride Syndrome: An Induced Delusional Disorder with the Potential of a Mass Psychogenic Illness?
Level 4 - case-series / case-control
Single case report accompanied by narrative commentary and expert hypothesis

What was done
The authors reviewed the concept and literature surrounding post-finasteride syndrome (PFS) and described a single clinical case of a 25-year-old male who developed persistent symptoms attributed to 5-alpha reductase inhibitor therapy after taking dutasteride for male androgenetic alopecia in a long-standing (over 20 years) dermatotrichology practice.
What was found
The abstract reports no quantitative data or statistical comparisons. Based on the single 25-year-old patient, the authors observed circumstantial features suggesting that PFS symptoms may represent a delusional disorder of the somatic type, potentially arising on a background of a histrionic personality disorder and high suggestibility.
Why it matters
This article articulates an alternative psychiatric and nocebo-driven hypothesis for post-finasteride syndrome symptoms, arguing against a direct pharmacological or neuroendocrinological toxic etiology.
Limits
The report is restricted to a single patient (n=1) who took dutasteride rather than finasteride, preventing any causal or epidemiological generalization. The proposed psychogenic and delusional mechanism is speculative, based entirely on subjective clinical impression without standardized psychiatric testing or controlled comparison.
