    TLDR Some hormone-related drugs may protect brain cells in Parkinson's disease differently in men and women.
    The document from August 1, 2016, explores the neuroprotective potential of estrogenic drugs and 5α-reductase inhibitors in Parkinson's disease (PD), with a focus on sex differences in PD incidence and progression. It reports that estrogen and compounds like raloxifene, progesterone, and dehydroepiandrosterone (DHEA) have shown neuroprotective effects in animal models, potentially mediated through estrogen receptors such as GPER1. The document also notes that 5α-reductase inhibitors like Dutasteride, which are used for benign prostatic hyperplasia and androgenic alopecia, have demonstrated neuroprotective effects in male mice. The findings suggest that these compounds could be optimized for personalized PD treatments based on sex, but more research is needed to fully understand their mechanisms and effectiveness. The research was supported by grants from the Canadian Institutes of Health Research and other scholarships.

      community DHT/Testosterone levels in scalp Fin VS Dut.

      in Finasteride/Dutasteride  60 upvotes 4 months ago
      Dutasteride raises scalp testosterone by 99%, which may not be ideal for those sensitive to all androgens. Some argue finasteride's balancing act might be better, while others believe dutasteride is superior for hair regrowth.

      community DHT and 5AR respect post, it's importance within the brain

      in Research/Science  111 upvotes 8 months ago
      The conversation discusses whether to use finasteride for hair loss, considering its role in inhibiting DHT and 5AR, which can affect brain function and mood. Some users report anxiety and depression from finasteride, while others do not experience these side effects and emphasize the importance of DHT for brain and prostate health.

      community Proof that finasteride messes with neurosteroids

      in Research/Science  230 upvotes 4 months ago
      Finasteride can impact neurosteroids, potentially causing depression and other side effects in some users. Despite these concerns, many continue using it for hair loss, with some switching to topical applications to mitigate side effects.

      community A hill on which I will die: The DHT itch absolutely exists

      in Research/Science  210 upvotes 6 months ago
      The DHT itch is linked to hair loss and persists despite finasteride use; switching to dutasteride helped alleviate the itch and promoted regrowth. Some users suggest seborrheic dermatitis as a cause and recommend treatments like medicated shampoos, vitamin D, and minoxidil.

      community Having androgen receptor density and sensitivity at wrong f*ing place

      in Satire  7 upvotes 1 month ago
      The conversation discusses hair loss treatments, focusing on the use of topical minoxidil, microneedling, finasteride, and dutasteride, while debating the role of testosterone and DHT in hair loss. It also touches on the potential liver health impacts of these treatments and the genetic sensitivity of hair follicles to androgens.
