Abstract
Environmental exposures are widely recognized as major risk factors for human health. According to projections by the World Health Organization, climate change is expected to cause a significant increase in mortality within the next few decades. Environmental factors, including diet, weather, occupational exposures, and pollutants play a key role in human diseases affecting different systems, such as cardiovascular, pulmonary, gastrointestinal, and neurological. This narrative review explores the relationship between environmental stressors and neuropathological mechanisms, such as microglial and astrocytic activation, oxidative stress, and neuronal injury, involved in neuroinflammation and the associated neurodegeneration. The pathogenesis and progression of Alzheimer’s disease is discussed in detail, establishing a link between environmental stressors and neuroinflammation. A deeper understanding of these neuropathological mechanisms may guide the development of preventive and therapeutic strategies to safeguard brain health in the context of global environmental change.
