The progressive brain disorder known as Dementia remains one of the most mysterious conditions — researchers aren’t sure why some people get it, how to prevent it, or how to cure it. But in recent years, science has uncovered some intriguing clues, including some red flags in the blood which may indicate an increased risk of dementia. Several are within your power to change. Read on to learn more – and to ensure your health and that of others, don’t miss this one Sure Signs You’ve Already Had COVID.
In September, Japanese researchers published findings that 33 metabolic compounds in the blood in people with dementia are different than in older people with normal cognition. These compounds can lead to brain damage and they can help isolate a cause of dementia or allow for better diagnostic testing.
In a study published this fall the news PLOS BiologyAustralian researchers said they may have identified a possible cause of Alzheimer’s disease. The animal study found that excessive toxic fat-protein complexes in the blood can damage small blood vessels in the brain and leak into the organ itself, causing inflammation and killing brain cells. Making dietary changes or taking medications can reduce the amount of these toxins in the blood, which could reduce the risk of Alzheimer’s or slow the progression of the disease, the study’s lead author said.
According to a 2014 study published in Neurology, people with blood type AB are 82 percent more likely to develop thinking and memory problems that can lead to dementia than people with other blood types. The possible culprit: Factor VII, a protein that helps blood clot. People with AB blood have, on average, higher levels of factor VII than people with other blood types, and high levels of factor VII are associated with a higher risk of dementia.
In a study published last summer in Lancet Healthy Longevity, researchers found that high LDL (“bad”) cholesterol may increase the risk of developing dementia later in life. Looking at health data from more than 1.8 million people over the age of 40 followed for up to 23 years, scientists found that high LDL cholesterol levels in middle age were associated with an increased risk of dementia more than a decade later.
Several studies have linked uncontrolled diabetes with an increased risk of dementia. One of the latest: a study published in the journal last June Neurology, which found that older people who visited the hospital for high and low blood sugar events were six times more likely to develop dementia than people who had experienced neither. People who only had low blood sugar had a 75% higher risk of dementia than people without the condition, and people with only high blood sugar had more than twice the risk. “Our findings suggest that exposure to severe glycemic events may have long-term effects on brain health and should be considered an additional motivation for people with diabetes to avoid severe glycemic events throughout their lives,” said the lead author of the research.
