As we age, levels of key hormones like estrogen, progesterone, and testosterone begin to decline, which can have a significant impact on brain function. This hormonal imbalance has been linked to memory loss, cognitive dysfunction (brain fog), and the progression of neurodegenerative conditions such as Parkinson’s, Alzheimer’s, and dementia. These disorders are often driven by chronic inflammation and oxidative stress in the brain, processes that hormones help regulate. When hormone levels are balanced, the brain is better equipped to stay sharp, resilient, and focused. Because of this connection, hormone therapy is gaining attention as a supportive approach to protecting long-term cognitive health.
