Study Finds Heavy Metal Cadmium May Linked To Memory Issue
The heavy metal cadmium, which is found in the air, water, food, and soil, is known to cause health problems. A new study published in Neurology examined if thinking and memory skills were associated with cadmium exposure.
They found no association when they looked at the group as a whole. However, when looking at Black and white people separately, it found cadmium may be tied to problems with thinking and memory skills in white people. The study found no such association in Black people. The study does not prove that cadmium causes memory problems in white people; it only shows an association.
Cadmium is a highly toxic heavy metal that enters the body mainly through cigarette smoking, breathing polluted air, and food. It is released into the environment through industrial and agricultural activities.
The study involved 2,172 people with an average age of 64 and no problems with thinking or memory skills. Black people made up 39% of the participants and white people made up 61%. Levels of cadmium in the urine were tested at the beginning of the study. Participants took tests of thinking and memory skills every year and were followed for an average of 10 years.
During that time, 195 people developed cognitive impairment. When researchers looked at the overall group, they found no association between cadmium levels and cognitive impairment. However, when they looked at Black and white participants separately, they found that white people with high levels of cadmium were more likely to develop cognitive impairment. They found no association in Black people.
With participants divided into two groups based on cadmium levels, white people with high levels were twice as likely to develop cognitive impairment as those with low levels, even after adjusting for other factors that could affect cognitive impairment, such as physical activity, alcohol use and education. A total of 9.2% of those with high levels developed thinking and memory problems, compared to 6.7% of those with low levels.
