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.

,
January 2009 in “Epilepsia” In this study, status epilepticus in rats induced P450scc in hippocampal glia, which was associated with a delayed onset of spontaneous seizures, while inhibiting neurosteroid synthesis accelerated seizure onset if P450scc was significantly increased.

,
January 2008 in “Biological & Pharmaceutical Bulletin” In this study, finasteride dose-dependently inhibited stress-induced increases in allopregnanolone in rats, while enhancing 20alpha-reduction of progesterone without affecting 3alpha-dihydroprogesterone or 11-deoxycorticosterone levels.
81 citations
,
June 2006 in “Experimental Neurology” Neurosteroids may help prevent seizures in epilepsy.
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.

February 1999 in “PubMed” This study found that the anticonvulsant effects of progesterone against PTZ-induced seizures in mice require conversion to allopregnanolone, as shown by the reversal of these effects with a 5alpha-reductase inhibitor.
