Glossary Neurosteroids

steroids produced in the brain that affect neuron function

Neurosteroids, also known as neuroactive steroids, are a class of steroids synthesized in the brain and nervous system. They play a crucial role in modulating neuronal activity, influencing mood, stress response, and cognitive functions by interacting with neurotransmitter receptors such as GABA and NMDA.

research Stress-Induced Deoxycorticosterone-Derived Neurosteroids Modulate GABA_AReceptor Function and Seizure Susceptibility

269 citations , May 2002 in “Journal of Neuroscience”

This study observed that acute stress in rats increased neurosteroid levels linked to enhanced GABA(A) receptor function, raising seizure thresholds, while similar effects were seen in mice with deoxycorticosterone administration.

research Neurosteroidogenesis Is Required for the Physiological Response to Stress: Role of Neurosteroid-Sensitive GABA_AReceptors

248 citations , December 2011 in “Journal of Neuroscience”

This study demonstrated that stress-derived neurosteroid THDOC shifts from inhibiting to activating the HPA axis under stress, presenting potential therapeutic targets for stress-related disorders.

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 Anticonvulsant Activity of Progesterone and Neurosteroids in Progesterone Receptor Knockout Mice

180 citations , June 2004 in “Journal of Pharmacology and Experimental Therapeutics”

This study found that progesterone's antiseizure effects in mice occurred primarily through conversion to allopregnanolone, rather than through the progesterone receptor, as evidenced by results in PR knockout mice.

research Testosterone modulation of seizure susceptibility is mediated by neurosteroids 3α-androstanediol and 17β-estradiol

136 citations , January 2004 in “Neuroscience”

This study found that testosterone increased seizure severity in mice and rats, with its neurosteroid metabolites playing a role in modulating seizure susceptibility.

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 - impact on Neurosteroids, which yes, \are important and not a garbage hormone

in Research/Science 163 upvotes 1 year ago

Finasteride may affect neurosteroids, impacting mood and sexual function, with varied user experiences. Some report side effects like depression and sexual dysfunction, while others find it effective for hair retention or prefer alternatives like Dutasteride or topical treatments.

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 5 alpha reductase type 1 is in brain tissue producing the main endogenous gabaergic allopregnanolone, not 2. How can finasteride as a 5ar2 lower that?

27 upvotes 1 year ago

Finasteride and dutasteride are discussed for hair loss, with concerns about their effects on neurosteroids and potential side effects like depression. Alternatives like topical estrogen and lifestyle changes are considered, with varying opinions on mental health and hair regrowth.
