The impact of nutritional, environmental, and lifestyle factors on neurological disorders: therapeutic implications and mechanistic insights
Abstract
Neurological disorders like Alzheimer's, Parkinson's, multiple sclerosis, and primary psychiatric conditions are complex, arising from a mix of genetic and modifiable risks. Growing evidence indicates that nutrition, environment, and lifestyle significantly influence disease development, progression, and treatment response. Nutrients such as vitamins, minerals, omega-3 fatty acids, and polyphenols affect neuroinflammation, oxidative stress, mitochondrial health, and neurotransmitter function. Dietary patterns like the Mediterranean and ketogenic diets offer protective benefits in clinical and experimental contexts. Meanwhile, environmental neurotoxicants-air pollution, heavy metals, pesticides, and endocrine disruptors contribute to neurodegeneration via oxidative damage, synaptic impairment, and epigenetic alterations. Lifestyle factors, such as physical activity, sleep, stress, and substance use, affect brain plasticity, neurogenesis, and metabolic health, thereby influencing disease progression over time. These factors often share common pathways such as oxidative stress, inflammation, vascular injury, mitochondrial dysfunction, and protein misfolding, underscoring the need for a comprehensive prevention and treatment strategy. Emerging therapies now incorporate personalized nutrition, lifestyle changes, and environmental risk mitigation alongside traditional drugs, supported by advances in multi-omics, digital health, and systems biology. Public health efforts to reduce…
