Recent research revealed that the microbes in the human body’s intestines act as an early warning system to alert to the possibility of Alzheimer’s disease, indicating a possible method of diagnosis for millions of people with the disease around the world, according to a report by the “Science Alert” website.
The “gut microbiome” is the collection of microbes, which includes bacteria, viruses and fungi in the gut, and scientists believe its diversity is important to overall human health.
However, in certain circumstances, the ‘gut microbiome’ can also contain microbes that are harmful to our health.
In Alzheimer’s disease, two proteins, known as amyloid beta and tau, build up abnormally in the brain, and their presence leads to the characteristic memory loss and cognitive decline associated with the disease, with symptoms gradually worsening over time.
Scientists discovered that long before Alzheimer’s symptoms appear, differences and changes occur in the ‘gut microbiome’.
The scientists found that including gut microbiome data improved the algorithm’s ability to accurately diagnose preclinical Alzheimer’s disease.
And by analyzing a person’s “gut microbiome”, which only requires a sample of “stool”, the risk of developing Alzheimer’s disease can be assessed.
This would provide an “easy, non-invasive way” to identify people at risk of developing Alzheimer’s disease at an early stage, allowing them more time to plan and prepare for the future.
Alzheimer’s is a “brain disorder that worsens over time,” characterized by changes in the brain that lead to deposits of certain proteins, and is the most common cause of dementia, according to the Mayo Clinic website.
About 6.5 million people with Alzheimer’s disease live in the United States at the age of 65 and older, and there are more than 55 million people around the world with dementia, according to the United Nations.
