What is the Origin of Cognitive Erosion?

This term bridges clinical neurology with endocrinology, describing the cumulative impact of systemic physiological stress on higher cortical functions. 'Erosion' metaphorically captures the slow, pervasive nature of this decline, contrasting with acute neurological events. It is frequently linked to long-term alterations in sex steroid or thyroid hormone signaling within the brain.

What is the Mechanism of Cognitive Erosion?

The erosion mechanism often involves impaired neurogenesis and synaptogenesis, processes highly dependent on factors like BDNF, which are themselves influenced by hormones like testosterone and estrogen. Chronic high cortisol levels can induce hippocampal atrophy, directly compromising memory circuits. Furthermore, compromised cerebral glucose utilization due to metabolic shifts exacerbates this functional decline.

Cognitive Erosion

Meaning

Cognitive Erosion refers to the gradual, progressive decline in executive function, memory consolidation, and mental clarity often observed in states of chronic hormonal imbalance or metabolic dysregulation. It represents the functional degradation of neuroendocrine feedback mechanisms and neural plasticity due to sustained suboptimal internal milieu. This condition manifests as reduced cognitive throughput and resilience.
