Glossary Neurosteroid Synthesis

Neurosteroid synthesis refers to the production of steroid hormones within the brain and nervous system, which can influence various physiological processes, including mood, cognition, and stress response. In the context of hair loss, neurosteroids may play a role in modulating hair follicle biology and the hair growth cycle, particularly through their effects on androgen receptors and local hormonal balance. Key distinguishing characteristics of neurosteroids include their ability to rapidly affect neuronal function and their synthesis from cholesterol or other steroid precursors within the central nervous system.

research Neurosteroid Synthesis-Mediated Regulation of GABA_AReceptors: Relevance to the Ovarian Cycle and Stress

238 citations , February 2007 in “Journal of Neuroscience”

This study found that neurosteroids can reorganize GABA A receptors in mice, mimicking ovarian cycle changes, with the process being mediated by neurosteroid levels rather than direct hormone receptor activation.

research Inhibition of neurosteroid synthesis increases asphyxia-induced brain injury in the late gestation fetal sheep

100 citations , April 2007 in “Neuroscience”

This study found that treatment with finasteride in fetal sheep reduced the protective neurosteroid allopregnanolone, leading to increased cell death in the hippocampus following induced fetal asphyxia.

research Temporal lobe epilepsy exacerbation during pharmacological inhibition of endogenous neurosteroid synthesis

13 citations , February 2013 in “BMJ Case Reports”

This case report suggests that discontinuing finasteride, which may affect neurosteroids synthesis, improved seizure control in a woman with temporal lobe seizures.

research Corticosterone enhances the potency of ethanol against hippocampal long-term potentiation via local neurosteroid synthesis

11 citations , July 2015 in “Frontiers in Cellular Neuroscience”

This study found that corticosterone promotes neurosteroid synthesis in hippocampal neurons, which can lead to ethanol-mediated synaptic dysfunction even at moderate ethanol levels, potentially contributing to stress-related cognitive impairment from alcohol.

research Witnessed trauma exposure induces fear in mice through a reduction in endogenous neurosteroid synthesis

7 citations , March 2024 in “Journal of Neuroendocrinology”

In this study, researchers found that both direct and witnessed trauma in mice are associated with reduced levels of the neurosteroid allopregnanolone, potentially influencing PTSD outcomes, and that treatment with synthetic neurosteroids may mitigate fear responses linked to observed trauma.

community Androsterone as a Neurosteroid Replacement Strategy for 5α-Reductase Inhibitor–Associated Sexual and Affective Dysfunction

in Research/Science 36 upvotes 2 months ago

Androsterone may help with sexual and affective dysfunction from finasteride by replacing disrupted neurosteroids without increasing androgenic side effects. Controlled testing is needed to confirm its effectiveness and safety.

community Finasteride, Neurosteroids, and Neuroplasticity - have you noticed cognitive shifts or have you continued growing?

in Basic Questions 201 upvotes 3 months ago

The conversation discusses concerns about potential cognitive and emotional effects of finasteride, with the original poster planning to monitor their cognitive performance while using the treatment. A user responds that most people do not experience cognitive shifts, though some report subtle changes.

community What is the real impact of dutasteride on neurosteroids? A little review of 2 scientific datas

in Research/Science 21 upvotes 2 years ago

Dutasteride at 0.5 mg/day does not significantly alter allopregnanolone levels, but higher doses (2.5 mg/day) do. Dutasteride may also have anti-neuroinflammatory effects, but the impact on neurosteroids is still debated.

community Why do people here trust Kevin Mann?

36 upvotes 6 years ago

Concerns about finasteride's side effects on neurosteroids and brain health, with skepticism towards Kevin Mann's advice. Users discuss using finasteride, minoxidil, and RU58841 for hair loss, with mixed opinions on their safety and effectiveness.

community Low cortisol it is due the fin

7 upvotes 1 year ago

The user has been taking 1mg finasteride daily for a year with no improvement in hair loss and reports low cortisol levels, sleep issues, and anxiety changes. The conversation includes discussions on the potential effects of finasteride on cortisol and neurosteroids, with suggestions to consult a doctor and consider other factors.
