Assignment Question
Use only peer-reviewed sources. Alzheimer’s disease (AD) and Parkinson’s disease (PD) are common neurodegenerative diseases. They are debilitating conditions that affect the memory and movement of affected individuals, respectively. The incidence of AD and PD has been growing by leaps and bounds in the past 50 years and many have suggested a myriad of causes. However, some recent research has provided a link between neurodegenerative diseases and heavy metal toxicity.
1) What are heavy metals and how are they able to kill neurons (quote a primary source in a scientific/medical journal for 3 different heavy metals)?
2) What are the most common sources of these 3 heavy metals in everyday life?
3) Were these products in existence 100 or 200 years ago when the rate of neurodegenerative diseases was much lower?
4) Are these 3 substances known to cause or exacerbate other diseases besides neurodegeneration?
5) What can be done to prevent tissue damage from these substances? Organize answers by number.
