What is the Origin of Cognitive Function Perimenopause?

This clinical concept arises from the intersection of endocrinology and neurocognition, recognizing the brain as a primary target organ for sex steroid hormones. The perimenopausal period, characterized by hormonal volatility, is a distinct biological event prompting these cognitive changes. The term emphasizes that these functional alterations are not solely age-related but are directly influenced by the reproductive aging process.

What is the Mechanism of Cognitive Function Perimenopause?

Estradiol exerts neuroprotective and neuromodulatory effects by interacting with estrogen receptors in the hippocampus and prefrontal cortex, areas vital for memory and executive function. The mechanism of decline involves the withdrawal of estradiol, which can lead to reduced cerebral glucose utilization, decreased synaptic plasticity, and altered neurotransmitter signaling. These physiological changes underlie the temporary or persistent decline in cognitive performance experienced during the menopausal transition.

Cognitive Function Perimenopause

Meaning

Cognitive function in perimenopause refers to the changes observed in executive functions, memory, attention, and processing speed during the transitional phase leading up to menopause. Many women experience subjective cognitive complaints, often described as “brain fog,” which are clinically linked to the fluctuating and eventual decline of ovarian hormones, particularly estradiol. These neurohormonal shifts impact the brain regions responsible for higher-order thinking and memory consolidation.
