Is Parkinson’s disease genetic or environmental?

Since I’ve started working on this project, many people have asked me if Parkinson’s disease is “genetic or environmental”. One of the most frequently cited studies on this question looked at twin brothers: identical twins versus fraternal twins. If one twin got Parkinson’s, would the other twin get it as well?

If Parkinson’s was genetic, we would expect both identical twin brothers to get Parkinson’s more often than both fraternal twin brothers. Why is this? Because identical twins share much more genetic information than fraternal twins, who share as much genetic information as regular brothers. More genetic information means more likelihood that both identical twins will share traits, including disease risk, that are caused or influenced by heritable factors.

So what did the study find? …read more

Zinc and Parkinson's

Do diets low in zinc cause Parkinson’s?

Do diets low in zinc cause Parkinson’s? If people are anything like yeast they may. Scientists found a protein clumping phenomenon in yeast that is similar to what is seen in Parkinson’s and Alzheimer’s. This particular clumping is caused by a deficiency in zinc. So scientists are now studying the association of zinc with Parkinson’s disease in humans. Vegetarians with diets rich in whole grains are often deficient in zinc.

  • Description: “Scientists have made a discovery that, if replicated in humans, suggests a shortage of zinc may contribute to diseases like Alzheimer’s and Parkinson’s, which have been linked to defective proteins clumping together in the brain.
