Abstract

5-MeO-DMT may evoke temporary epileptiform activity linked to its unique effects.

5-MeO-DMT exhibits distinct subjective effects compared to typical psychedelics.
The acute and post-acute effects of 5-MeO-DMT resemble those observed during seizures.
Aberrant functioning of 5-HT receptors is noted in epilepsy, which 5-MeO-DMT may influence.
Reactivations of drug effects after 5-MeO-DMT could indicate recurrent epileptiform activity.
Further research is warranted to explore 5-MeO-DMT's therapeutic mechanisms.

Simplified

5-MeO-DMT is a tryptamine being developed as a potential antidepressant that may display a distinct therapeutic mechanism due to its unique pharmacology and subjective effects compared to typical psychedelics. In this article, we parallel the relatively distinct phenomenology and behavioral effects of the acute and post-acute effects of 5-MeO-DMT to those induced by epileptiform activity, particularly in instances within epileptogenic zones of the temporal lobes. This is done by reviewing aberrant 5-HTreceptor functioning in epilepsy, noting that 5-MeO-DMT has notable 5-HTreceptor agonist properties-and then comparing the acute behavioral and subjective effects induced by 5-MeO-DMT to those that occur in seizures. It might be that 5-MeO-DMT's therapeutic mechanism is partly mediated by evoking temporary epileptiform activity, suggesting a similarity to electroconvulsive therapy. It is also noted that "reactivations," the sudden re-experiencing of drug effects common after 5-MeO-DMT but not after typical psychedelics, may suggest that 5-MeO-DMT produces recurrent epileptiform activity. Overall, this review indicates that further evaluation of 5-MeO-DMT's unique mechanisms in research settings and among naturalistic users are warranted. 1A1A
