What is Alzheimer's Disease?

Scientists aren’t absolutely sure what causes cell death and tissue loss in the Alzheimer's brain, but the plaques and tangles are prime suspects.

Does Memory Loss Always Mean Dementia?

Dementia is a broad category of symptoms that affect the brain and causes memory loss.

Early onset Alzheimer's

Although, Alzheimer’s is viewed as a disease of the elderly, up to 5% of Americans with Alzheimer’s have the early-onset variety, which can start to show symptoms as early as one’s 30s.

Blood test for Alzheimer’s? New antibody test could accurately detect Alzheimer’s before symptoms appear

Blood test for Alzheimer’s

US researchers have developed an antibody test that can precisely detect if Alzheimer’s exist in a person before the symptoms appear. The test set to be available soon, will give physicians a chance to intercede at the earliest stage of the disease when treatment is possible.

Alzheimer’s disease is the most common form of dementia. It is fatal and progressive. The accumulation of amyloid plaques and neurofibrillary tangles are the prime suspects behind damage and death of nerve cells that destroy a person’s memory and cognitive skills.

The cause of Alzheimer’s is unknown and there is no cure for the disease, but different drug and non-drug therapies can make a person live ably with the disease.

Alzheimer’s is the 6th leading cause of death in the United States. An estimated 5.3 million Americans have Alzheimer’s. [Read more Mushrooms May Be Effective In Fighting Off Aging]
In the UK, an estimated 850,000 people will have dementia by the end of 2015 and the number will rise to 1 million by 2025. Every year nearly 60,000 deaths are directly attributed to dementia.
However, there is no definitive blood test for Alzheimer’s that has been approved by the FDA.

The research presented by Dr. Robert Nagele, PhD, at the American Osteopathic Association’s Osteopathic Medical Conference and Exposition (OMED15) in Orlando, Florida explains how antibodies act as blood-based biomarkers in order to detect countless diseases and identify the progression stage of the stage.

The researchers based their work on the hypothesis that thousands of autoantibody present in human blood specifically sticks to blood-borne cellular waste produced by organs and tissues in the body.  

A person’s gender, age and the presence of particular disease plays a role on his or her autoantibody profile. Attribute changes in autoantibody caused by diseases can perform as biomarkers that exhibit the presence of the disease.

In Alzheimer’s, changes in the brain start to occur years before the symptoms appear. If the doctors are able to detect antibodies at the preclinical stage, it would give the patients a chance to work with the physicians to make lifestyle changes and receive treatments before symptoms appear. This process could eliminate or delay the most damaging symptoms.

While the cause of Alzheimer’s is unknown, researchers believe that a critical preventative measure can be taken by maintaining a healthy blood-brain barrier. [মধুর যত মধুর গুণাবলী]

Dr. Nagele points to the benefits of early detection of diseases because various conditions leading to vascular disease and risk factors for Alzheimer’s are similar. People who have preclinical disease can attempt to enhance their vascular health, such as controlling their diet, exercising and take steps to manage problems with blood pressure and weight in order to ward off slow progression of Alzheimer’s.

Other diseases such as Parkinson’s disease, multiple sclerosis (MS) and breast cancer could also be detected by this test. [Read more Eating alone may have dangerous effects on your health]


According to Jennifer Caudle, assistant professor of family medicine at Rowan University, physicians always endorse a healthy lifestyle to prevent diseases, but many people disregard the advice until a health crisis happens.
