What is the Origin of Systemic Cognitive Degradation?

This term synthesizes observations from geriatric medicine, neuroendocrinology, and metabolic psychiatry, emphasizing the non-linear relationship between systemic health and brain function. It moves beyond isolated cognitive deficits to acknowledge the pervasive impact of peripheral factors, such as insulin resistance or chronic cortisol elevation, on central nervous system integrity. The term underscores the body-brain connection in healthspan.

What is the Mechanism of Systemic Cognitive Degradation?

Degradation is mediated by chronic systemic factors that compromise neuronal health, including sustained neuroinflammation, impaired cerebral glucose metabolism, and oxidative stress. Hormonal dysregulation, such as low thyroid hormone or chronic HPA axis activation, directly impairs hippocampal function and synaptic plasticity. Addressing the systemic root causes, like insulin resistance, is therefore a critical strategy for neurocognitive preservation.

Systemic Cognitive Degradation

Meaning

A broad clinical descriptor for the progressive, multi-domain decline in mental capacities, including memory, executive function, attention, and processing speed, resulting from chronic, underlying systemic dysregulation. This degradation is often a consequence of sustained hormonal imbalance, chronic inflammation, or metabolic dysfunction, rather than a primary neurological disease. It signifies a loss of neurological reserve and functional efficiency.
