Alzheimer’s disease affects over is the most common form of dementia. It is an irreversible, progressive condition that affects memory, cognitive abilities, and behaviour.
Patients with Alzheimer’s disease gradually lose their ability to function in day-to-day life without care and assistance.
According to the Alzheimer’s Association, more than 342,000 Australians are living with dementia—a number expected to increase to 400,000 in less than a decade.
Patients with Alzheimer’s disease gradually lose their ability to function in day-to-day life without care and assistance. The exact cause of the disease is not known, but many factors play a role. Amalgam fillings have been associated with increased risk of Alzheimer’s.
Studies are revealing that mercury poisoning can increase the risk of Alzheimer’s disease.
As a neurotoxin mercury exposure produces a number of harmful effects on the brain. It mainly increases oxidation damage which may have impacts
Increases cell death in the adult neural cells (4)
Depletes glutathione (antioxidant) pathway reducing the brain’s ability to protect itself
Harms lipid and protective layers
Damages DNA in the brain
Increases build-up of tau and amyloid plaques in the brain
These mechanisms are all associated with neurodegenerative disorders such as ALS (Amyotrophic lateral sclerosis) and Alzheimer’s disease.
While research is yet to show exactly the risk between mercury fillings and Alzheimer’s disease, those at high risk should consider their exposure to mercury from all sources.
One study in 1998 showed that increased blood levels of mercury could increase the cell death associated with Alzheimer’s disease (5)
