Neuroendocrine aging refers to the study of how changes in the endocrine system (hormones) and the nervous system affect the aging process. This research area focuses on understanding how changes in hormones and neurotransmitters can impact cognitive function, physical health, and overall well-being as individuals age. Researchers in this field investigate how age-related changes in the endocrine and nervous systems contribute to conditions such as cognitive decline, mood disorders, and age-related diseases. Additionally, they explore potential interventions and treatments to maintain or improve neuroendocrine function in older adults.
