Environmental Pollutants and Aggressive Climatic Conditions:Combination Scaffolds of Brain Stroke

In the present scenario, health-related complications are worsening because of escalating environmental factors. Pollution of the earth has reached alarming levels. High motorization rate and unchecked industrial wastes produce massive environmental pollutants, which are the most profound factors for aggressive climatic conditions. Heat-trapping pollutants like carbon monoxide and chlorofluorocarbons are increasingly being emitted in the atmosphere. Many toxic pollutants, viz. sulphur dioxide, nitrogen dioxide, mercury and lead have crossed their threshold levels in urban and industrial regions. These pollutants have serious consequences on human health, affecting many organs and systems. They affect our respiratory system, circulatory system and nervous system by entering the blood stream. The blood–brain barrier of the central nervous system is also being disrupted due to sustained exposure. Ischaemia and haemorrhage are the most hazardous incidences of environmental pollutants in brain. It has now become a serious cause of morbidity and mortality. Pollutants like sulphur dioxide and carbon monoxide have a tendency to produce ischaemia and clump through inflammation and arterial blockage. Almost 40% of mortality is caused due to pollution-induced brain stroke. Hence, environmental pollutants are the leading cause of cerebral stroke and somatic disabilities.
