Did you mean Mendelian randomization?

Glossary Mendelian randomization

uses genetic variations to infer causal relationships in biology

Mendelian randomization is a research method that uses genetic variations to study the causal effects of a modifiable exposure (like diet or lifestyle) on a disease. By leveraging the random assortment of genes from parents to offspring, it mimics the design of a randomized controlled trial, helping to determine whether an observed association between a risk factor and a health outcome is likely to be causal rather than due to confounding factors.

community Hair Loss Causes Depression. Not Finasteride.

187 upvotes 7 months ago

Finasteride and Dutasteride do not cause depression or mood disorders; hair loss itself may be a more significant factor. Some users experience side effects from Finasteride, but it is generally well-tolerated.

community Hair Loss Ruins Your Mind: 10x rate of BDD. PF S is not real

in Research/Science 39 upvotes 7 months ago

Hair loss is linked to a higher rate of body dysmorphic disorder (BDD), OCD, and depression. Finasteride and dutasteride are not linked to increased suicidal risk, though some users report mental health side effects.
