Estrogen and Brain Function:

Mental Clarity Through Menopause


By Hana Paterno, ND | October 29, 2019

Today, mental clarity is vital not only to health, but to the ability to function well at work, home, and in the world at large. During the perimenopausal and menopausal transition, estrogen and progesterone levels decline, leading to a host of symptoms including loss of mental clarity. Brain fog is a commonly used term that describes this loss of mental clarity, in which sufferers experience difficulty with memory, word recall, and concentration. While there are multiple etiologies of brain fog, studies have shown that hormonal imbalance is a poignant factor.  

Estrogen promotes cognitive function in several ways, including the promotion of neuroplasticity, which is crucial for healthy brain function. Estrogen affects neuroplasticity by promoting neurotrophins, such as nerve growth factor (NGF) and brain derived neurotrophic factor (BDNF). Neurotrophins influence the survival, development, and function of neurons. As estrogen levels decline with age, NGF and BDNF also decline, leading to a decrease in neuroplasticity and thus, a decline in mental clarity. In addition to promoting neuroplasticity, estrogen helps to improve mitochondrial function, promotes ATP production, and helps to regulate glucose metabolism. It has antioxidant effects, protecting against reactive oxygen species, DNA damage, and cell death.  

Estrogen receptors have been found throughout the brain and many studies have demonstrated the effectiveness of estrogen replacement therapy on brain function, even showing preventative promise in Alzheimer's disease and improved cognition in Alzheimer’s patients. It has been shown to increase trophic (growth) factors, thereby decreasing beta-amyloid development within the brain. Estrogen also influences neurotransmitter systems such as serotonin, glutamate and acetylcholine, which affect learning, memory, and communication between neurons and other nerve cells. Transdermal estradiol demonstrates increased serotonin receptor binding in the right frontal cortex, enhancing executive function and psychomotor speed. 

If declining hormone levels or hormone imbalance is suspected in patients with brain fog, consider Doctor’s Data/Labrix salivary Comprehensive Hormone Profile which measures estrogen, progesterone, testosterone, DHEA, and diurnal cortisol. Salivary hormone testing can provide insight into a potential etiology to brain fog, which will help determine treatment considerations. Urinary neurotransmitter testing can be paired with salivary hormones to provide a more comprehensive evaluation of brain function.
