how do genetics and family history contribute to Alzheimer’s risk?

Genetics and family history play a significant role in the development of Alzheimer’s disease. While the exact cause of Alzheimer’s is still unknown, scientists have identified several genes that can influence a person’s susceptibility to the disease.

One of the most well-known genes associated with increased risk is called apolipoprotein E (APOE). There are three forms of this gene: APOE ε2, APOE ε3, and APOE ε4. While everyone has two copies of the APOE gene (one inherited from each parent), inheriting one or two copies of the APOE ε4 variant increases the risk and lowers the age of onset of Alzheimer’s disease. On the other hand, inheriting the APOE ε2 variant may have a protective effect.

Family history also contributes to Alzheimer’s risk. Having a first-degree relative (such as a parent or sibling) with the disease increases a person’s likelihood of developing it as well. However, it’s important to note that having a family member with Alzheimer’s doesn’t guarantee that an individual will develop the disease.

It’s worth mentioning that genetics and family history are just two factors among many that contribute to Alzheimer’s risk. Other factors, such as age, lifestyle choices, and overall health, also play a role. If you have concerns about Alzheimer’s or its risk factors, it’s always a good idea to consult with a healthcare professional for personalized information and guidance.

Genetic blood pressure and cholesterol revealed to cause ‘Alzheimer’s’

Although medical experts do not have a clear answer to why alzheimer’s disease is a disabling disease, some reasons are attributed to it.

But now a new study has revealed that Alzheimer’s disease can also be caused by genetic problems of cholesterol and blood pressure.

According to the medical journal JAMA Network, experts reviewed the data of 450,000 people to find a link between genetic cholesterol and blood pressure with Alzheimer’s.

The people examined by the experts were from 11 different countries of Europe and about 40,000 of them were diagnosed with Alzheimer’s, while about 400,000 people did not have any Alzheimer’s disease.

When the experts reviewed the data, it was found that the people who suffered from Alzheimer’s had a higher amount of good cholesterol, which is commonly called HDL.

Similarly, systolic blood pressure levels were also found to be higher in people suffering from Alzheimer’s.

The problem of high cholesterol and blood pressure in all people with Alzheimer’s was genetic, that is, they inherited the problem from family diseases and complications.

According to experts, generally high levels of good cholesterol i.e. HDL protect against diseases like stroke and heart attack, but it is considered a risk for mental and mental diseases.

Similarly, experts said that increasing 10 units of low blood pressure is also likely to increase Alzheimer’s disease, but this problem can occur in people who have a genetic problem of blood pressure.

At the same time, experts clarified in the research that the above research cannot be considered ideal, because all the people involved in it belonged to the same region i.e. Europe region, but more research should be done in this regard so that good cholesterol and blood pressure are related to Alzheimer’s.

Experts also say that Alzheimer’s is usually caused by the growth of the protein ‘amyloid beta’ present in the plasma and this protein sometimes starts to grow a decade ago.

Although there is no authentic cure for this disease, medical experts try to reduce its severity through various medicines and exercises.

This disease affects the brain, memory is lost, often it preys on elderly people, but people of any age can have this disease and as it has been said that it is incurable, catching it at an early stage helps to avoid it.

What dangerous disease can the habit of putting a finger in the nose cause?

The habit of putting a finger in the nose is not only in children but also in some young and elderly people, which can also cause a disease that is not easy to get rid of.

A 2022 study revealed an unusual link between the habit of putting a finger in the nose and Alzheimer’s disease caused by brain cell infection.

The habit of putting a finger in the nose not only destroys the internal cells of your nose but also provides an easy way for bacteria to reach the brain through the nose, which affects the brain cells.

How Alzheimer’s begins is still a mystery, although a lot of research has been done on it.

Experts say that the habit of putting a finger in the nose could possibly be the cause of the onset of the disease.

A team of researchers led by scientists from Griffith University in Australia tested the bacteria called ‘Chlamydia pneumonia’ which can cause pneumonia in humans, some of the patients who suffer from Alzheimer’s, the same bacteria were discovered in the brain.

In a study conducted on mice, the researchers believed that the bacteria in the brain can reach there through the nose.

James St. John, a neuroscientist at Griffith University, said in a 2022 statement, "We first sent chlamydia pneumoniae bacteria directly into the brain through the nose, and then what we saw is potentially frightening for humans."

Scientists were surprised to see the bacteria spread rapidly in mice and engulf the nervous system, this infection occurs in 24 to 72 hours, showing that any virus or bacteria reaches the brain rapidly through the nose.

Although it is not certain that the effects will be the same in humans.

According to James St. John, we need to do this study in humans and confirm whether it is completely correct for humans as well.

Researchers say that this research has been proposed by many people but it has not yet been completed, we believe that the same bacteria is also in the human brain, but it is not final how it reaches the brain.

Researchers discover more benefits of oleic acid found in Olive oil

Olive oil contains oleic acid in the form of fatty acids that remove cancer, heart disease and Alzheimer’s

Just as turmeric is a curcumin chemical present in it, oleic acid in olive oil is also its most important ingredient. Now more medical benefits have been discovered.

All types of olive oil contain 70 to 80 percent of oleic acid. Now experts from the University of Seville, Al-Jaraf Institute and Costa del Civil Hospital in Spain have done an important study. According to scientists, oleic acid is found in the form of fatty acids in olive oil and has proved to be very useful for the heart.

Oleic acids energize cell membranes and molecules and also play an important role in antioxidants. Then in a very deep way, it prevents cholesterol, thus protecting against blood thickening and heart disease. On the other hand, to reduce inflammation in the body, it contains important components that repel the attack of cancer.

Prevention of Obesity

Oleic acid also plays an important role in preventing obesity and obesity. Apart from this, they also protect DNA abnormally. The same research has shown that olilithinol amide, an important component derived from oleic acid, has antioxidant and anti-inflammatory properties. Experts believe that this ingredient can be an important drug in preventing obesity. Apart from this, it also strengthens the immune system by keeping the cells in the best condition.

People who suffers regularly with viral infections can have neuro-diseases

A long and comprehensive study has shown that people who suffer from various viral infections multiple times are more likely to have neurodegenerative diseases.

Neurodegenerative diseases affect the central nervous part of the human body that is connected by the brain and spinal cord.

Neurodegenerative diseases are usually a combination of six diseases, but they can also include more diseases.

Such diseases include Alzheimer, Parkinson’s, dementia, multiple sclerosis, spinal muscular atrophy and lower body disease, but they can also have more diseases.

Neurodegenerative diseases are called mental and neurological diseases that affect memory, thinking, speaking, walking, walking and life routine, and there is no cure for such diseases yet, but health experts try to control them with various medicines.

It is generally believed that these diseases are caused by obesity, but a recent comprehensive study showed that people who suffer from viral infections multiple times in life are more likely to have such diseases.

According to research published in the medical journal Neuron, British experts reviewed medical data from 800,000 people in Finland and the UK to find a link between neurodegenerative diseases and viral infections.

Researchers first found people with the help of data who were suffering from neurodegenerative diseases.

Later, researchers reviewed the medical records of all these people and tried to find out how many of them had been treated for viral infections before falling prey to these diseases.

Experts found that most of Finland’s people who were suffering from neurodegenerative diseases were undergoing treatment for 45 different viral infections.

After this, the researchers also examined the medical records of people in Britain and found that people suffering from neurodegenerative diseases there were also undergoing treatment for 22 different viral infections.

Research has shown that viral infections are closely related to neurological and mental diseases and different viruses have the ability to weaken the human body by attacking its nerves.

Experts suggested that more research should be done on the above issue.

It should also be remembered here that there are currently more than 219 viral infections around the world that have the full potential to attack the human body and make it sick, while there are some infections that prove to be very dangerous.

Scientists from four countries have developed an antibody test to identify Alzheimer’s disease

The prevalent test to identify Alzheimer’s and dementia has its flaws, but now a team of international scientists has developed a new blood test that can reliably predict the disease accurately.

 

Traditionally, brain imaging, cell analysis, and other methods are used to identify Alzheimer’s. These include lumbar puncture, in which a tube can be inserted in the lower part of the waist and analyzed by taking cerebrospinal fluid coming from the brain. Then tau proteins and amuloids are detected in them. This process is very expensive and painful.

Your retina can reveal mental health or disease

New research on the eyes has revealed that the stripes on the back of the retina, a sensitive tissue that senses light in the eye, may be related to mental capacity and health.

The most important disease in this regard is Alzheimer’s which gradually destroys the mental capacity. The disease progresses quietly but it is too late when severe symptoms appear. However, the day is not far off when eye examination can predict the condition prematurely, which is a common and severe form of dementia.

According to Ashley Bert Young, a professor at the University of Otago in New Zealand, and her research colleagues, eye examinations can be used to diagnose mental illness, especially Alzheimer’s. According to him, mental condition and mental condition can be examined through the window of eyes.

Ten years ago, it was discovered that the retina of Alzheimer’s patients tends to get thinner and thinner. Then, in 2018, it was discovered that Alzheimer’s has three eye conditions, including cataracts and aging-related blindness or AMD.

The University of Otago began the study in the 1970s. One thousand babies born in the 70’s were enrolled in the study. All the children had their eyes opened in the same hospital. Now, 50 years later, 865 adults have been examined who underwent various eye scans at the age of 45. In addition, all participants underwent other eye tests.

In the final examination, the thickness of the layers of retina and ganglion cells of all participants was carefully noted. Now, those who had thin retinas performed poorly in the brain and acquisition tests, that is, even in adolescence and even in childhood, they were behind others in these tests.

But retinal detachment has not been linked to overall cerebral palsy. All the children were mentally retarded at an early age. But statistical analysis has shown that the abnormal decrease in retinal thickness indicates that there is some reduction in brain, mental and cognitive capacity.

However, scientists have stressed the need for further research and more extensive studies will be carried out in the next phase.
