Proximity to major roads linked to increased risk of dementia, Parkinson’s, Alzheimer’s and MS

As a senior citizen whose family has Alzheimer’s Disease and other forms of dementia on both sides, I take these studies very seriously

Living near major roads or highways is linked to higher incidence of dementia, Parkinson’s disease, Alzheimer’s disease and multiple sclerosis (MS), suggests new research published this week in the journal Environmental Health.

Researchers from the University of British Columbia analyzed data for 678,000 adults in Metro Vancouver. They found that living less than 50 meters from a major road or less than 150 meters from a highway is associated with a higher risk of developing dementia, Parkinson’s, Alzheimer’s and MS—likely due to increased exposure to air pollution.

The researchers also found that living near green spaces, like parks, has protective effects against developing these neurological disorders.

Air pollution may be related to heightened dementia risk – Study

British researchers found that people exposed to increased levels of air pollution had 40 percent higher chances of developing dementia.

Air pollution is an established risk factor for heart disease/stroke and respiratory disease, but its potential role in neurodegenerative diseases, such as dementia, isn’t as clear.

The researchers used carefully calculated estimates of air and noise pollution across Greater London to assess potential links with new dementia diagnoses.

They looked at patient data on 131,000 Londoners aged 50 to 79, and based on their residential postcodes, the researchers estimated their yearly exposure to air pollutants. These were specifically nitrogen dioxide, fine particulate matter and ozone, as well as proximity to heavy traffic and road noise, using modelling methods validated with recorded measurements.
