Study Notes

Impact of Diet and Exercise on Brain Health

Pathogenesis of many neurological disorders involves an energy component
Top 10 leading causes of death in the US in 2010 include heart disease, cancer, and Alzheimer’s disease
Metabolic disorders such as diabetes reduce brain capacity and increase the risk of neurological disorders
Chronic obesity is associated with structural brain changes and increased risk for neurological and psychiatric disorders
Rise in consumption of sugars is associated with increased incidence of obesity
Saturated fats and sugars, when consumed in excess, are associated with obesity, metabolic syndrome, and increased risk for Alzheimer’s disease and depression
Omega-3 fatty acids, particularly DHA, are crucial for brain structure and function, impacting learning, memory, emotions, and protecting against neurodegeneration
Exercise helps counteract the effects of unhealthy diets by restoring brain-derived neurotrophic factor (BDNF) and cognitive loss
Exercise improves brain function, decreases anxiety, improves focus and concentration, promotes growth of new brain cells, and protects the brain from aging and neurodegenerative diseases
Exercise reduces cognitive impairment in aging, increases brain volume, and improves cognitive performance
Diet and exercise have collaborative effects on the central nervous system and periphery, promoting membrane homeostasis, neuronal signaling, and synaptic plasticity
Epigenetic mechanisms mediate the complex interactions between genetic factors and the environment, influencing brain health and cognitive reserve
