Treatments with anticancer chemotherapeutic agents often are toxic to the cells of the brain, leading to memory loss and cognitive dysfunction that can persist long after the period of exposure. This condition, termed chemo brain, appears to be due to DNA damages that cause epigenetic changes in the brain that accelerate the brain aging process ...
Human brain in the sagittal plane Ventricles of the brain. Aging entails many physical, biological, chemical, and psychological changes and the brain is no exception to this phenomenon. These various changes have attempted to be mapped by conceptual models like the Scaffolding Theory of
In the brain, serotonin is a neurotransmitter and regulates arousal, behavior, sleep, and mood, among other things. [9] During prolonged exercise where central nervous system fatigue is present, serotonin levels in the brain are higher than normal physiological conditions; these higher levels can increase perceptions of effort and peripheral muscle fatigue. [9]
“Estrogen, particularly estradiol, the strongest form, plays a critical role in the brain’s health and functionality, earning it the title of the ‘master regulator’ of women’s brain health.
There has yet to be a distinct link between the two because it is hard to determine exactly how each aspect of aging effects the memory and aging process. However, it is known that the brain shrinks with age due to the expansion of ventricles causing there to be little room in the head. Unfortunately, it is hard to provide a solid link between ...
Aging is characterized by a progressive loss of physiological integrity, leading to impaired function and increased vulnerability to death. The hallmarks of aging are the types of biochemical changes that occur in all organisms that experience biological aging and lead to a progressive loss of physiological integrity, impaired function and, eventually, death.
Strength of natural selection plot as a function of age. The antagonistic pleiotropy hypothesis (APT) is a theory in evolutionary biology that suggests certain genes may confer beneficial effects early in an organism's life, enhancing reproductive success, while also causing detrimental effects later in life, contributing to the aging process.
It can make you feel tired and hungry, which can lead to unhealthy food choices. To combat this, Werner suggests munching on foods that stabilize blood sugar , lowering insulin levels to keep you ...
