Over time, research has shown that air pollution is harmful to our health. Not only does it affect our heart and lungs, but it can also lead to deteriorating brain health.

Alzheimer’s and Parkinson’s diseases are two neurodegenerative diseases that can result from exposure to air pollution.

The correlation between air pollution and neurological diseases

Research has shown that air pollution can have adverse effects on the brain. Although the brain is a protected organ in the body, microscopic air pollutants can still penetrate the brain cells and cause damage.

The small particles known as PM 2.5 can enter the brain through the bloodstream, triggering inflammation in the brain’s cells. As a result of the inflammation, neurons can die, leading to cognitive decline.

Air pollution and Alzheimer’s disease

Alzheimer’s disease is a progressive disorder of the brain that causes memory loss and a decline in cognitive abilities. The disease is caused by the accumulation of beta-amyloid protein in the brain.

Studies have shown that long-term exposure to air pollution can lead to the accumulation of amyloid proteins in the brain, leading to Alzheimer’s disease. The accumulation of amyloid proteins is a result of exposure to airborne particles that can enter the brain and trigger inflammation, leading to the destruction of neurons which then leads to cognitive decline.

Air pollution and Parkinson’s disease

Parkinson’s disease is a disorder of the nervous system that affects the movement of the body. The disease is caused by the degeneration of dopamine neurons in the substantia nigra area of the brain.

Studies have shown that exposure to certain chemicals present in air pollution can cause oxidative stress in the brain, leading to the destruction of dopamine neurons. Lack of dopamine in the brain leads to the symptoms typical of Parkinson’s disease, including tremors and stiffness.

Preventing neurodegenerative diseases caused by air pollution

Although it may be challenging to avoid air pollution altogether, there are steps one can take to reduce exposure. These steps include:.

Avoiding areas with heavy traffic or industrial areas.
Using air filters in homes and offices.
Wearing masks when exposed to polluted air.
Using public transportation or investing in electric cars.

The future of research on air pollution and neurological diseases

Although research has shown that there is a correlation between exposure to air pollution and neurological diseases, the exact mechanisms by which air pollution leads to brain damage remain unknown.

The need for more research to determine the exact link between air pollution and neurological diseases is evident. Researchers and policymakers must come together to implement policies aimed at reducing the emission of pollutants and improving the quality of the air we breathe.

Conclusion

Poor air quality contributes significantly to Alzheimer’s and Parkinson’s diseases.

Exposure to air pollutants such as PM 2.5 and chemicals found in air pollution can lead to the accumulation of amyloid proteins in the brain, leading to Alzheimer’s disease. Additionally, exposure to certain chemicals in air pollution can cause oxidative stress in the brain, leading to the destruction of dopamine neurons, which leads to Parkinson’s disease.

Reducing exposure to air pollution can help to reduce the risk of developing these neurodegenerative diseases.
