Genetic expressions, combined with neurochemical and metabolic changes and environmental insults, may result in the display of mental disorder characteristics. Evidence indicates that structural brain abnormalities can be related to some mental illnesses, such as schizophrenia, depression, and Alzheimer disease. Natural and manmade disasters, such as hurricanes, floods, violence, terrorism, war, and the global economic crisis are profound stress-inducing events that can lead to mental illness. Researchers reported high levels of PTSD among survivors.
