    TLDR Neuroactive steroids may affect the risk and treatment of alcohol use disorders.
    The document from 2019 examines the role of neuroactive steroids, such as allopregnanolone and THDOC, in the brain's response to alcohol and their potential link to alcohol use disorders (AUD). It highlights that acute alcohol consumption can increase neuroactive steroid levels, which may contribute to alcohol's rewarding effects and protect against excessive drinking. However, chronic alcohol use can lead to a decrease in these levels, potentially increasing AUD risk. The document also notes that genetic variations affecting neuroactive steroid production may influence an individual's susceptibility to AUD. While the effects of ethanol on neuroactive steroid concentrations vary across species, brain regions, and types of exposure, the findings suggest that targeting neuroactive steroids could offer a new therapeutic approach for AUD. The number of participants in the studies referenced is not specified in the summary.

      community risks with finasteride and dutasteride

      in Research/Science  138 upvotes 2 weeks ago
      Finasteride and dutasteride have potential risks, including post-finasteride syndrome, but are commonly used for hair loss. RU58841, minoxidil, and needling are suggested as alternatives, though all treatments carry risks.

      community Proof that finasteride messes with neurosteroids

      in Research/Science  230 upvotes 1 year 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.

      Hair loss treatments, including microneedling, minoxidil, finasteride and RU58841; the efficacy of these treatments; criticisms of Kevin Mann's content related to his selective data presentation and biases towards certain treatments; and other topics such as DHT being labeled a "trash hormone" and critiques of other hairloss YouTubers.
