Dehydroepiandrosterone: a neuroactive steroid

Area of Science:

• Neuroendocrinology
• Neurochemistry

Background:

• Dehydroepiandrosterone (DHEA) and its sulfate (DHEAS) are adrenal steroids also produced in gonads and the brain.
• DHEA readily crosses the blood-brain barrier and is synthesized locally within brain tissue.

Purpose of the Study:

• To provide an overview of dehydroepiandrosterone's actions in the brain.
• To highlight neurosteroid mechanisms and potential roles in brain disorders.

Main Methods:

• Literature review of DHEA's neuroactivity.
• Analysis of DHEA's conversion to active metabolites (testosterone, dihydrotestosterone, estradiol).
• Examination of DHEA's interaction with androgen and estrogen receptors and non-genomic pathways.

Main Results:

• DHEA influences mood, emotions, and behavior as a neuroactive hormone.
• DHEA exhibits neuroprotective and antiglucocorticoid properties.
• DHEA administration may improve well-being and aid in treating depressive disorders.

Conclusions:

• DHEA functions as a significant neurosteroid with diverse actions in the brain.
• Understanding DHEA's mechanisms offers prospects for managing various brain disorders.
• Further research into DHEA's role in neurodegenerative diseases is warranted.
