Causes of Alzheimer’s Disease That You Must Know

Health & Wellbeing


There are many reasons you must know that can Causes To Alzheimer’s Disease, but what are those? 

Alzheimer’s disease occurs mostly in old age, but many other causes, such as head injury, Down’s Syndrome, genetics, and false lifestyle, increase the risk of Alzheimer’s disease development. The reason is similar for every cause the thickness of blood cells starts to change, amyloid protein plaques in the brain, and different areas of the brain shrink.

Our experts have mentioned most of the causes that might be the reason for Alzheimer’s disease. Keep reading to know more. 

Causes To Alzheimer’s Disease

Many causes could lead to Alzheimer’s disease. You must eat healthily and avoid drugs as they can lead you to memory loss at an early age.

So you must follow a healthy routine and lifestyle to avoid Alzheimer’s. However, within a time, you may develop symptoms of Alzheimer’s, and it increases as you grow older.

Here we have mentioned the cause of Alzheimer’s that you must know.

1. Aging

Most researchers have found the symptoms of  Alzheimer’s disease among older people around 60 to 65, and an average of 1/3 of those 85 age older already have Alzheimer’s disease. 

However, the risk among young people is less due to the brain producing immune cells to protect it from harmful neurons. Plus, most women have Alzheimer’s, and many studies confirm that it is possibly due to the loss of the hormone estrogen after menopause.

With age-related changes in the brain, scientists are finding the cause of simulating other kinds of brain cells and destroying neurons that cause Alzheimer’s in old age.

The reason is that your bones, skin, and brain weaken as you age. So, the atrophy shrinks or contrasts in certain brain parts, including vascular damage, inflammation, and brain-producing unstable molecules known as free radicals, breaking the energy production in brain cells. 

Although age is not the only risk factor among Alzheimer’s patients, some people go through a minor memory loss in their 90s which is a typical age factor. Aging people should receive therapy for Alzheimer’s disease hence symptoms occur. 

2. Genetical Changes

Genetics is the main reason most people in their 50s start to panic by forgetting something. However, it could be due to stress or a load of work. And later in age, genetics might be the reason for your memory loss. 

Moreover, most people develop Alzheimer’s disease because of genetics, but there is a slight chance of developing this disease. 

Parent genes can pass disease through the disease. So, Biological parents’ genes may impact their children, and they risk developing Alzheimer’s. 

If a person is inherent with a specific disease, then changes occur in genes one or more that can cause the disease. The genes pass infections such as Alzheimer’s, Sickle cell anemia, and cystic fibrosis. 

The genetic variant also causes or prevents the development of a specific disease or Alzheimer’s if genes change. However, if the genetic variant grows, disease risk facts but not directly called a genetic risk factor.

Moreover, changes or differences in genes can increase the possibility of infecting by disease, and that’s why most families have a history of illness. Genetic components can cause two types of Alzheimer’s early-stage and late-stage. 

3. Environmental and Lifestyle Facts

Your environment and lifestyle affect the brain and lead to Alzheimer’s disease. As per research, the reason beyond genetics for the development of Alzheimer’s disease can be hosted due to an unhealthy lifestyle, stress, and other factors.  

Heart disease, stroke, high blood pressure, and metabolic disease could lead to Alzheimer’s. However, we will understand through ongoing research about how and whether reducing the risk and factors of these health conditions help us to reduce the Alzheimer’s risk. 

Eating fat and junk food increases the chances of health issues leading to Alzheimer’s. So you must eat nutritious food, exercise daily, sleep eight hours, refresh mentally, and engage aids socially to stay healthy as you grow old.

Also, alcohol is must avoided as it can cause an increment in Alzheimer’s disease and other parts of the brain at an early age. 

Also, these exercises will reduce the risk of Alzheimer’s and cognitive decline. If you imply these healthy rituals early in life, it will change your brain and mental condition.

4. Down Syndrome

Down Syndrome is a higher risk of having Alzheimer’s disease because the genetic changes syndrome will provoke amyloid plaques to build up over time in the brain. And that can lead to Alzheimer’s disease in some cases. 

People with Down’s syndrome can develop Alzheimer’s in their 40’s or 50′. The activities in the brain are traced as they start to change, seen only in Alzheimer’s patients. 

Individuals with down syndrome get more changes in brain cells due to aging. And many different parts of the brain countered the extended impact of these two alterations. 

Alteration of neurons develops neurofibrillary tangles, flame-shaped formed mainly to reduce the cytoskeletal proteins. Beta/ A4 Amyloid- another protein, is traveled in large amounts around blood vessels in the shape of senile plaques and amyloid angiopathy. 

The expansion of neurofibrillary tangles and senile plaques follows an expected pattern. To describe in the hippocampus, the group of Down people will start developing these symptoms at the age of 13 to 71. 

However, It is Possibly that pathological changes happen 20-30 years go as the disease function grows from mild to extreme.

5. Head injury 

People with severe head injuries are at a higher risk of developing Alzheimer’s disease. 

Suffering from accidents that have hit your head forcefully could lead to head injury or brain injury. If you are knocked out -unconscious, vomiting, mood swing or behavioral changes, severe headaches, facing problems with memories, and crying are the symptoms that indicate head trauma. 

Furthermore, to cure this might require head surgery, but it increases the chances of Alzheimer’s disease. 

Head or brain injury or TBI, known as concussion, involves and tracks the changes in brain function and structure. This will lead to cognitive problems, for instance, difficulty in making a decision, damaged social function, and memory deficits.

However, minor TBI raises the risk factors for Alzheimer’s disease as previous studies haven’t confirmed neural degeneration in the brain and the extent of conditions transfer patterns.

After the brain injury, the thickness of the cortical happens in your brain and is associated bain age. The medication is required to thin the blood cells, reducing the symptoms of memory loss and verbal fluency.

6. Most effective therapy for Alzheimer’s

Light therapy eases the symptoms of Alzheimer’s and improvement in the condition. It has a light of the whole spectrum around 5000 Lux to 10,000 LUX that helps the brain’s circadian rhythm. 

Exposure to light therapy is highly encouraged when the weather is cold mainly in winter. Also, particular or disabled individuals can take that light therapy easily.  

It can improve sleep disrupture, nighttime wandering, fever, and many other related symptoms that have shown improvements after light therapy. 

Moreover, it can cure and improve the other disease that can lead to Alzheimer’s, such as depression, dementia of any stage, and SAD. It helps to prevent those dark thoughts and uplifts the mood. 

However, with any benefit, we still recommend consulting with your doctor. So, it can diagnose according to your health condition. 

Bottom Line 

From the age of 60 to 65, many studies report they discovered the causes of Alzheimer’s Disease in the brain. However, typical memory loss begins at 85 of age. As you age, your bones, brain, and everything starts to weaken, so you must consult a doctor or consider therapy. 

Moreover, usual forms of Alzheimer’s disease affect different brain parts. Sometimes, the first symptom of this disease starts from eyesight and vocabulary problems instead than memory loss.
