Neuroplastic effects of pollution
Research indicates that living in areas of high pollution has serious long term health effects. Living in these areas during childhood and adolescence can lead to diminished mental capacity and an increased risk of brain damage. People of all ages who live in high pollution areas for extended periods place themselves at increased risk of various neurological disorders. Both air pollution and heavy metal pollution have been implicated as having negative effects on central nervous system (CNS) functionality. The ability of pollutants to affect the neurophysiology of individuals after the structure of the CNS has become mostly stabilized is an example of negative neuroplasticity.
__FORCETOC__
==Air pollution==
Air pollution is known to affect small and large blood vessels throughout the body.
High levels of air pollution are associated with increased risk of strokes and heart attacks.〔Hong et al., 2002 Y. C. Hong, J. T. Lee, H. Kim and H. J. Kwon, "Air pollution: a new risk factor in ischemic stroke mortality", ''Stroke'' 33 (9) (2002), pp. 2165–2169〕 By permanently affecting vascular structures in the brain, air pollution can have serious effects on neural functioning and neural matter. In dogs air pollution shows to cause damage to the CNS by altering the blood–brain barrier, causing neurons in the cerebral cortex to degenerate, destroying glial cells found in white matter, and by causing neurofibrillary tangles. These changes can permanently alter brain structure and chemistry, resulting in various impairments and disorders. Sometimes, the effects of neural remodeling do not manifest themselves for a prolonged period of time.
