Pylons: Linked to dementia
Tuesday November 11, 2008
By Nick Fagge
LIVING close to pylons and high-voltage cables doubles the risk of dying from Alzheimer’s disease and senile dementia, a study claims.
Researchers say they have found a direct link between the electromagnetic fields created by power lines and all types of dementia.
The study by doctors at Bern University’s Institute of Social and Preventative Medicine in Switzerland is the latest evidence pointing to the dangers posed by power lines.

The relation between residential magnetic field exposure from power lines and mortality from neurodegenerative conditions was analyzed among 4.7 million persons of the Swiss National Cohort (linking mortality and census data), covering the period 2000–2005. Cox proportional hazard models were used to analyze the relation of living in the proximity of 220–380 kV power lines and the risk of death from neurodegenerative diseases, with adjustment for a range of potential confounders. Overall, the adjusted hazard ratio for Alzheimer's disease in persons living within 50 m of a 220–380 kV power line was 1.24 (95% confidence interval (CI): 0.80, 1.92) compared with persons who lived at a distance of 600 m or more. There was a dose-response relation with respect to years of residence in the immediate vicinity of power lines and Alzheimer's disease: Persons living at least 5 years within 50 m had an adjusted hazard ratio of 1.51 (95% CI: 0.91, 2.51), increasing to 1.78 (95% CI: 1.07, 2.96) with at least 10 years and to 2.00 (95% CI: 1.21, 3.33) with at least 15 years. The pattern was similar for senile dementia. There was little evidence for an increased risk of amyotrophic lateral sclerosis, Parkinson's disease, or multiple sclerosis.

Living close to a powerline can double your chance of dying from Alzheimer's Disease
A large new study from Switzerland shows a significant dose-related increase in deaths from Alzheimer's Disease (AD) in people who have lived for a number of years within 50 metres of high-voltage overhead powerlines. The results of this new study considerably raises the stakes in the EMF-health debate by showing up a serious and wide-spread public ill health problem as being closely associated with power-frequency magnetic field exposure. The cost of dementia to the UK economy is estimated to be over £17 billion (GBP) per year.
