What is the Origin of Androgenic Effect on Cognition?

The understanding of this relationship stems from classical endocrinology and the subsequent development of neuroendocrinology, acknowledging the brain as a primary target organ for steroid hormones. Early clinical observations of cognitive changes following castration or androgen replacement therapy provided the empirical basis for this specialized field of study. Contemporary research focuses on the molecular pathways and receptor distribution within the hippocampus and prefrontal cortex.

What is the Mechanism of Androgenic Effect on Cognition?

Androgens cross the blood-brain barrier, binding to androgen receptors (AR) located in key brain regions involved in memory and mood regulation. This receptor binding alters gene transcription, influencing neurogenesis, synaptic plasticity, and the production of neurotrophic factors. Furthermore, testosterone can be aromatized to estrogen, which also plays a significant neuroprotective role, highlighting the complex, multifaceted nature of the androgenic effect on neuronal health and cognitive performance.

Androgenic Effect on Cognition

Meaning

This describes the influence that androgen hormones, primarily testosterone and its metabolites like dihydrotestosterone (DHT), exert on various domains of brain function. Androgens modulate cognitive processes, including spatial awareness, executive function, and verbal memory, through direct interaction with neuronal receptors. Maintaining optimal androgenic balance is recognized as critical for sustaining neurocognitive health across the lifespan, particularly in aging populations.
