Alzheimer's and Pesticides: Growing Link

Several studies have shown a strong link between exposure to pesticides and herbicides and the development and rapid progression of Alzheimer’s dementia.

Similar studies have shown a link to other neurodegenerative diseases, such as:

• Parkinson’s disease

• ALS

• Polyneuropathy

• Multiple sclerosis

One early hint was that the incidence of Alzheimer’s was much higher among farmers, who are more frequently exposed to organophosphate and/or organochlorine insecticides than the rest of the population.

Studies have also shown that the brains of patients dying from Alzheimer’s had much higher levels of pesticides such as DDE, beta-HCH, and diedrin than the unaffected population.

Pesticides have a number of modes of action that can trigger brain injury, including producing high levels of free radicals and lipid peroxidation products, reducing brain energy production, activating brain microglia (immunoexcitotoxicity), triggering the production of beta amyloid (organophosphates such as chlorpyrifos) and hyperphosphorylated tau, pathological events in Alzheimer’s, and impairing antioxidant defenses.

One of the worst pesticides is glyphosphate (an ingredient in Roundup), which has been shown to trigger intense generation of free radicals and lipid peroxidation products within the brain and liver.

It also alters neural membrane function.

One of the major problems is that these pesticides accumulate in fatty tissue. The brain has very high levels of fat.

In addition, pesticides tend to accumulate in the environment, meaning they slowly increase their concentration in food, water, and air — even within cities.

Millions of tons of these pesticides are used every year, mainly for crops that are not used as foodstuffs but rather as ingredients, such as corn for making high fructose corn syrup.

Because these toxic substances accumulate, even low doses can be responsible for the rising incidence of Alzheimer’s we are now seeing.

The only answer seems to be organic farming until safer methods of insect, weed, and fungal control can be found.
