AB is the least common blood type, found in about 4 percent of the U.S. population. The study found that people with AB blood were 82 percent more likely to develop the thinking and memory problems that can lead to dementia than people with other blood types.
No significant association between ABO blood groups and Alzheimer's disease was found by Renvoize11 or, more recently, by Vasan and collegues12. The interest in the link between ABO antigens and neurological disorders has been recently renewed thanks to two further published studies13,14.
Brain Function and Memory Loss
People who have blood types A, B, and AB are up to 82 percent more likely to develop cognition and memory problems — which can lead to dementia — compared to those with Type O.
Seventy-three percent are age 75 or older. About 1 in 9 age 65 and older (10.7%) has Alzheimer's. Almost two-thirds of Americans with Alzheimer's are women. Older Black Americans are about twice as likely to have Alzheimer's or other dementias as older Whites.
We all inherit a copy of some form of APOE from each parent. Those who inherit one copy of APOE-e4 from their mother or father have an increased risk of developing Alzheimer's. Those who inherit two copies from their mother and father have an even higher risk, but not a certainty.
Scientists believe that for most people, Alzheimer's disease is caused by a combination of genetic, lifestyle and environmental factors that affect the brain over time. Less than 1% of the time, Alzheimer's is caused by specific genetic changes that virtually guarantee a person will develop the disease.
Alzheimer's disease is thought to be caused by the abnormal build-up of proteins in and around brain cells. One of the proteins involved is called amyloid, deposits of which form plaques around brain cells. The other protein is called tau, deposits of which form tangles within brain cells.
The risk of developing Alzheimer's or vascular dementia appears to be increased by many conditions that damage the heart and blood vessels. These include heart disease, diabetes, stroke, high blood pressure and high cholesterol.
AB is the least common blood type, found in about 4 percent of the U.S. population. The study found that people with AB blood were 82 percent more likely to develop the thinking and memory problems that can lead to dementia than people with other blood types.
Of the eight main blood types, people with type O have the lowest risk for heart disease. People with types AB and B are at the greatest risk, which could be a result of higher rates of inflammation for these blood types. A heart-healthy lifestyle is particularly important for people with types AB and B blood.
Carriers of blood group 0 (I) are generally more resistant to diseases, with the exception of H. pylori-associated gastrointestinal diseases. Carriers of «antigenic» blood groups A (II), B (III), AB (IV) are more susceptible to development of infectious, cardiovascular and cancer diseases.
Previous studies have shown that for the overall U.S. population, Black Americans are roughly 1.5 to 2 times as likely than whites to develop Alzheimer's and related dementias.
Studies show that dementia risk is lowest in people who have several healthy behaviours in mid-life (aged 40–65). These behaviours include: ∎regular mental, physical and social activity ∎not smoking ∎drinking alcohol only in moderation ∎keeping a healthy diet.
As the exact cause of Alzheimer's disease is still unknown, there's no certain way to prevent the condition.
Some risk factors for dementia cannot be altered, such as increased age or family history. However, people can modify other risk factors to reduce risk. For example, smoking, obesity, and excessive use of alcohol are all risk factors for Alzheimer's disease and related dementias.
In the CAIDE study, coffee drinking of 3-5 cups per day at midlife was associated with a decreased risk of dementia/AD by about 65% at late-life. In conclusion, coffee drinking may be associated with a decreased risk of dementia/AD.
Not getting enough sleep for a long time may increase a level of protein in your brain called Tau, which is directly related to cognitive decline and can cause Alzheimer's disease. 3.
According to the Alzheimer's Research and Prevention Foundation, regular physical exercise can reduce your risk of developing Alzheimer's disease by up to 50 percent. What's more, exercise can also slow further deterioration in those who have already started to develop cognitive problems.
White foods, including pasta, cakes, white sugar, white rice and white bread. Consuming these causes a spike in insulin production and sends toxins to the brain. Microwave popcorn contains diacetyl, a chemical that may increase amyloid plaques in the brain.
Women are disproportionately affected by Alzheimer's disease (AD). Nearly two-thirds of the more than 5 million Americans living with Alzheimer's are women and two-thirds of the more than 15 million Americans providing care and support for someone with Alzheimer's disease are women.
