Does particulate matter cause Alzheimer’s? US researchers present new study

Why do people get Alzheimer's disease? The disease has many reasons, according to US researchers. Among them: The pollution by fine dust. This threatens the diesel after the exhaust scandal new trouble.

Does particulate matter cause Alzheimer’s? 

Not only since the discussion about driving bans for cars with diesel engines, mankind deals with fine dust. Minute particles that are omnipresent in the air pollute the human lung and cause respiratory or cardiovascular disease. But does fine dust also have an effect on the brain?

Researchers from the US now want to have found a link between the burden of particulate matter and Alzheimer’s disease. According to the dust should be a trigger of the disease. They claim this in a new study. It was published in the ” Journal of Environment Research “.

Deposits in the brain

To prove this effect, the scientists looked at the brains of 203 younger deceased (1-40 years). At this point, it was ensured that all “subjects” came from Mexico City – a city with extremely high particulate matter pollution. According to the US Environmental Protection Agency (EPA), the pollution in Mexico City is well above the limit values.

The youngest brain examined belonged to an eleven-month-old boy. Already in such a young organ, the researchers found something remarkable: the autopsy revealed deposits of particulate matter in the brain, which could have led to Alzheimer’s in the future.

According to researchers at the University of Montana, Alzheimer’s disease begins in the brainstem of infants.

How do you recognize Alzheimer’s? 

Alzheimer’s is an autopsy in the brain that is visible through protein particles. These can not be dismantled. These particles are considered a disease feature long before the disease actually breaks out. If the protein particles are not broken down, they contribute to the fact that in the brains of affected people gradually die off healthy brain cells and so dissolve synapses between cells.
