What is the Origin of DHEA Executive Function?

This concept stems from the field of neuroendocrinology, which investigates the influence of hormones on brain function, particularly the decline observed with age-related decreases in DHEA-S levels. DHEA is classified as a neurosteroid because it is synthesized de novo in the brain and modulates neurotransmission. The term directly links the presence of this specific steroid to the performance of complex cognitive tasks.

What is the Mechanism of DHEA Executive Function?

DHEA exerts its influence by acting as a positive allosteric modulator of the N-methyl-D-aspartate (NMDA) receptor, thereby facilitating excitatory neurotransmission and synaptic plasticity crucial for learning and memory. It also counteracts the effects of stress hormones like cortisol, helping to maintain neuronal health and reduce excitotoxicity in the hippocampus and prefrontal cortex. This neuroprotection directly supports the efficient processing required for executive function.

DHEA Executive Function

Meaning

DHEA Executive Function describes the specific, measurable impact of the neurosteroid Dehydroepiandrosterone (DHEA) and its sulfated form (DHEA-S) on the brain’s high-level cognitive processes. Executive function encompasses a set of mental skills, including working memory, cognitive flexibility, inhibitory control, and goal-directed behavior. Adequate DHEA levels are recognized as crucial modulators for maintaining the integrity and efficiency of these complex frontal lobe activities.
